    PURPOSE: To investigate the surgical safety and benefits of using the BirdView camera system with a wide field of view in robotic surgery for rectal cancer in a prospective clinical study. METHODS: This study included 20 consecutive patients who underwent robotic surgery at our institution between the years 2022 and 2023. The primary endpoint was perioperative safety, which was defined as the occurrence of adverse events, including other organ injuries and malfunctions, caused by the BirdView camera system. RESULTS: There were no injuries to any other organs caused by the console surgeon or assistant forceps during surgery. Surgical adverse events occurred in five cases (atelectasis, paralytic ileus, and anastomotic leakage) during the postoperative course. There were no cases of device failure or damage to the surrounding organs, including peritoneal heat damage. CONCLUSIONS: We believe that the BirdView system could be valuable in improving the safety of robotic surgery by enabling the observation of blind spots, thus preventing harm to other organs.

    We carried out a retrospective observational investigation to explore the association of endotheliopathy with coagulofibrinolytic reactions and the progression of disseminated intravascular coagulation (DIC) in adult trauma patients. We measured syndecan-1 (SDC-1), an indicator of endotheliopathy, and biomarkers of coagulofibrinolysis in 100 trauma patients immediately transferred to Ehime University Hospital. We evaluated the correlations between the coagulofibrinolytic parameters and SDC-1. We also investigated the association between SDC-1 elevations and the development of DIC, and determined the discriminators of DIC development. The median SDC-1 concentration was 82.7 (43.5-178.1) ng/mL. DIC developed in 16 patients (16.0%), and SDC-1 concentrations were significantly higher in DIC patients than in non-DIC patients (218.8 [134.5-798.2] ng/mL vs. 67.2 [39.6-114.5] ng/mL, p < 0.001). Receiver operating characteristic curve analysis revealed that the circulating SDC-1 level effectively predicted the progression of DIC, with an area under the curve of 0.862 (95% confidence interval [CI], 0.789-0.936). The optimal cut-off value was determined to be 92.5 ng/mL, yielding a sensitivity of 100.0% and a specificity of 67.8% (p < 0.001). A simple logistic regression analysis showed that a circulating SDC-1 concentration of > 92.5 ng/mL was significantly correlated with DIC progression (odds ratio [OR], 31.67; 95%CI: 3.97-252.31, p = 0.001). Many coagulofibrinolytic parameters were significantly correlated with SDC-1. Estimating the discriminators of DIC development by the least absolute shrinkage and selection operator (LASSO) and elastic-net regression analysis identified markers of coagulofibrinolytic activation, such as thrombin-antithrombin complex (TAT) and tissue plasminogen activator (tPA). A multivariate logistic regression model using TAT, tPA, and SDC-1 demonstrated that TAT and tPA, but not SDC-1, were independent factors predicting the development of DIC (TAT per 10 µg/L: OR, 1.14, 95%CI: 1.05-1.24, p = 0.003; tPA per 100pg/mL: OR, 1.03, 95%CI: 1.01-1.05, p = 0.003; SDC-1 per 10ng/mL: OR, 1.00, 95%CI: 0.99-1.01, p = 0.973). Mediation analysis showed that SDC-1 elevation was predominantly associated with the development of DIC indirectly through the increase in TAT (proportion mediated = 96.1%, p < 0.001), while there was no significant indirect effect of SDC-1 elevation on the role of TAT elevation in DIC development was observed (p = 0.340). The primary pathogenesis of DIC in the acute phase of trauma is likely driven by coagulofibrinolytic activation. Endotheliopathy, as reflected by elevated circulating levels of SDC-1, is strongly associated with coagulofibrinolytic responses. Although endotheliopathy may contribute to the early development of DIC through coagulation activation, its role appears to be limited.

    A rectovaginal fistula (RVF) is an abnormal tract between the rectum and vagina, which requires surgical intervention in many cases. Although there are many different therapeutic approaches for RVF depending on the patient's' condition, there are no established guidelines for the care of RVF. This study aimed to evaluate the results of laparoscopic colostomy in advanced cancer patients with RVF, and the safety and efficacy of this surgery. In this study, seven female advanced cancer patients with RVF were hospitalized and successfully treated with laparoscopic colostomy from 2015 to 2018 at our university hospital. Their data were retrospectively evaluated from their medical records. The early use of diverting stomas facilitated timely resumption of cancer treatment and enabled early treatment with chemotherapy or radiotherapy. Although vaginal stool leakage affected three patients, all patients recovered, experiencing neither pain nor infection during their cancer treatment. While colostomy was physically and mentally taxing for the patients, it improved the infection and pain caused by the RVF. We conclude that the early use of diverting stomas had two effects: a significant improvement in infection management and facilitation of the rapid resumption of cancer treatment.

    Thrombocytopenia frequently occurs in patients with sepsis. Disseminated intravascular coagulation (DIC) may be a possible cause of thrombocytopenia owing to its high prevalence and association with poor outcomes; however, it is important to keep the presence of other diseases in mind in sepsis practice. Thrombotic microangiopathy (TMA), which is characterized by thrombotic thrombocytopenic purpura, Shiga toxin-producing Escherichia coli hemolytic uremic syndrome (HUS), and complement-mediated HUS, is characterized by thrombocytopenia, microangiopathic hemolytic anemia, and organ damage. TMA has become widely recognized in recent years because of the development of specific treatments. Previous studies have reported a remarkably lower prevalence of TMA than DIC; however, its epidemiology is not well defined, and there may be cases in which TMA is not correctly diagnosed, resulting in poor outcomes. Therefore, it is important to differentiate DIC from TMA. Nevertheless, differentiating between DIC and TMA remains a challenge as indicated by previous reports that most patients with TMA can be diagnosed as DIC using the universal coagulation scoring system. Several algorithms to differentiate sepsis-related DIC from TMA have been suggested, contributing to improving the care of septic patients with thrombocytopenia; however, it may be difficult to apply these algorithms to patients with coexisting DIC and TMA, which has recently been reported. This review describes the disease characteristics, including epidemiology, pathophysiology, and treatment, of DIC, TMA, and other diseases with thrombocytopenia and proposes a novel practical approach flow, which is characterized by the initiation of the diagnosis of TMA in parallel with the diagnosis of DIC. This practical flow also refers to the longitudinal diagnosis and treatment flow with TMA in mind and real clinical timeframes. In conclusion, we aim to widely disseminate the results of this review that emphasize the importance of incorporating consideration of TMA in the management of septic DIC. We anticipate that this practical new approach for the diagnostic and treatment flow will lead to the appropriate diagnosis and treatment of complex cases, improve patient outcomes, and generate new epidemiological evidence regarding TMA.

    There are many reports on the positional relationship between the ileocolic artery and superior mesenteric vein (SMV). However, there have been no reports of anomalous venous confluence in the ileocecal vessel area. A 69-year-old man was diagnosed with cecal cancer on a preoperative examination of a lung tumor. We planned to perform surgery for the cecal cancer. Computed tomography angiography revealed an anomalous vein confluence in the ileocolic region. We performed robot-assisted ileocecal resection. Although the small intestinal vein was misidentified as the SMV at first, we confirmed the misidentification, identified the SMV on the dorsal side of the ileocolic artery, and ligated the ileocolic vessels with precise forceps manipulation during robotic surgery. Especially for cases with vascular anomalies revealed by preoperative computed tomography angiography, robotic surgery may be useful, as flexible forceps manipulation prevents vascular injury.

    In this study, a murine sepsis model was developed using the cecum ligation and puncture (CLP) technique. The expression of the proinflammatory cytokines tumor necrosis factor alpha (TNF-α) and interleukin-1β (IL-1β) in the brain increased 6 h after CLP but decreased 24 h later when elevated endogenous dopamine levels in the brain were sustained. Methyl-4-phenyl-1,2,3,6-tetrahydropyridine hydrochloride reduced dopamine levels in the striatum and increased mortality in septic mice. Dopamine D1-like receptors were significantly expressed in the brain, but not in the lungs. Intraperitoneally administered SKF-81297 (SKF), a blood-brain barrier-permeable D1-like receptor agonist, prevented CLP-induced death of septic mice with ameliorated acute lung injury and cognitive dysfunction and suppressed TNF-α and IL-1β expression. The D1-like receptor antagonist SCH-23390 abolished the anti-inflammatory effects of SKF. These data suggest that D1-like receptor-mediated signals in the brain prevent CLP-induced inflammation in both the brain and the periphery.

    BACKGROUND: Complete mesocolic excision (CME) and central vascular detachment are very important procedures in surgery for colorectal cancer. Preoperative and intraoperative assessments of the anatomy of major colorectal vessels are necessary to avoid massive bleeding, especially in endoscopic surgery. A case with a rare anomaly in which the middle colic artery (MCA) and ileocolic artery (ICA) had a common trunk is reported. CASE PRESENTATION: The patient was a 73-year-old woman diagnosed with ascending colon cancer on colonoscopy. Preoperative abdominal contrast-enhanced computed tomography confirmed that the MCA and ICA had a common trunk. She underwent laparoscopic ileocecal resection for the ascending colon cancer with D3 lymph node dissection. Intraoperative indocyanine green fluorescence imaging was conducted. After confirming vessel bifurcation, the ICA was dissected at the distal end of the MCA bifurcation. The patient has been followed as an outpatient, with no signs of recurrence as of 2 years postoperatively. CONCLUSION: A case of an ascending colon cancer with a unique vascular bifurcation pattern was presented. Preoperative and intraoperative evaluations of the major colorectal vessels are very important for preventing perioperative and postoperative complications.

    To investigate dysphagia after extubation in patients with severe coronavirus disease 2019 (COVID-19). We retrospectively examined patients with severe COVID-19 treated in our hospital between August 2021 and March 2022. Feeding outcomes were categorized into two groups-(1) total oral intake, and (2) difficulty in oral intake. To assess the feeding outcome, we used modified water-swallowing test (MWST) for all patients. However, in cases where aspiration or recurrent laryngeal nerve palsy was suspected, we conducted the fiberoptic endoscopic evaluation of swallowing after MWST. Patient data were collected from medical records. Forty-six patients with severe COVID-19 were included. Among the 46 patients, 14 (30.4%) experienced difficulties with oral intake. Older age, longer length of hospitalization, duration of mechanical ventilation, tracheostomy, diabetes, and higher serum levels of C-reactive protein (CRP) and procalcitonin (PCT) at the time of intubation were associated with difficulty in oral intake. The rate of difficulty with oral intake in patients with severe COVID-19 was 30.4%, which is not as high as reported in previous studies. Older age, longer duration of mechanical ventilation, tracheostomy, diabetes, and higher levels of CRP and PCT were associated with the prevalence of oral intake difficulty, suggesting that early attention should be paid to high-risk patients who have preexisting deterioration of swallowing function due to aging and comorbidities, or who have prolonged intubation or tracheostomy to prevent aspiration pneumonia.

    BACKGROUND: Laparoscopic and robotic surgery for transverse colon cancer are difficult due to complex fusion of the foregut and midgut and variation of the vessels of the transverse colon. Although the vessels of the right colon have been investigated, middle colic artery (MCA) variation and the relationship with vessels around the transvers colon are unknown. We investigated variation of the MCA using computed tomography angiography (CTA) and cadaver specimen and the relationship between the superior mesenteric vein (SMV) and MCA using CTA. The classification of vessels around the transverse colon may lead to safer and reliable surgery. METHODS: This study included 505 consecutive patients who underwent CTA in our institution from 2014 to 2020 and 44 cadaver specimens. Vascular anatomical classifications and relationships were analyzed using CT images. RESULTS: The MCA was defined as the arteries arising from the superior mesenteric artery (SMA) that flowed into the transverse colon at the distal ends. The classifications were as follows: type I, branching right and left from common trunk; type II, the right and left branches bifurcated separately from the SMA; and type III, the MCA branched from a vessel other than the SMA. Type II was subclassified into two subtypes, type IIa with one left branch and type IIb with two or more left branches from SMA. In the CTA and cadaver studies, respectively, the classifications were as follows: type I, n = 290 and n = 31; type IIa, n = 211 and n = 13; type IIb, n = 3 and n = 0; and type III, n = 1 and n = 0. We classified the relationship between the MCA and left side of the SMV into three types: type A, a common trunk runs along the left edge of the SMV (n = 173; 59.7%); type B, a right branch of the MCA runs along the left edge of the SMV (n = 116; 40.0%); and type C, the MCA runs dorsal of the SMV (n = 1; 0.3%). CONCLUSIONS: This study revealed that The MCA branching classifications and relationship between the SMV and MCA. Preoperative CT angiography may be able to reliably identify vessel variation, which may be useful in clinical practice.

    RATIONALE: Venovenous extracorporeal membrane oxygenation (ECMO) is recommended for the treatment of critically ill patients with acute respiratory distress syndrome due to coronavirus disease 2019 (COVID-19). However, ECMO management can cause both bleeding and thrombotic complications. There are insufficient coagulofibrinolytic data for appropriate ECMO management in patients with COVID-19. PATIENT CONCERNS: A 48-year-old man with severe COVID-19-acute respiratory distress syndrome underwent long-term venovenous ECMO management for 48 days. Refractory oronasal bleeding developed on day 13, so the administration of unfractionated heparin was ceased for 29 days. DIAGNOSIS: The patient showed dynamic coagulofibrinolytic responses associated with ECMO management, as shown by fibrin/fibrinogen degradation products, soluble fibrin, thrombin-antithrombin complex, and plasmin-α2-plasmin inhibitor complex elevations, suggesting the development of ECMO-induced coagulopathy. INTERVENTIONS: We assessed coagulofibrinolytic markers to decide the appropriate timing for controlling excessive activation of coagulation by exchanging ECMO circuits. Moreover, viscoelastic hemostatic assays were used for adequate transfusion of blood products. OUTCOMES: Safe long-term ECMO management was completed, which was withdrawn on day 48. The patient was weaned off mechanical ventilation on day 57 and was transferred to another hospital for rehabilitation. LESSONS: Monitoring the coagulofibrinolytic status using markers and viscoelastic hemostatic assays may be effective for safe long-term ECMO management even without anticoagulant therapy.

    BACKGROUND: Tracheostomy is an important procedure for the treatment of severe coronavirus disease-2019 (COVID-19). Older age and obesity have been reported to be associated with the risk of severe COVID-19 and prolonged intubation, and anticoagulants are often administered in patients with severe COVID-19; these factors are also related to a higher risk of tracheostomy. Cricotracheostomy, a modified procedure for opening the airway through intentional partial cricoid cartilage resection, was recently reported to be useful in cases with low-lying larynx, obesity, stiff neck, and bleeding tendency. Here, we investigated the usefulness and safety of cricotracheostomy for severe COVID-19 patients. MATERIALS AND METHODS: Fifteen patients with severe COVID-19 who underwent cricotracheostomy between January 2021 and April 2022 with a follow-up period of ≥ 14 days were included in this study. Forty patients with respiratory failure not related to COVID-19 who underwent traditional tracheostomy between January 2015 and April 2022 comprised the control group. Data were collected from medical records and comprised age, sex, body mass index, interval from intubation to tracheostomy, use of anticoagulants, complications of tracheostomy, and decannulation. RESULTS: Age, sex, and days from intubation to tracheostomy were not significantly different between the COVID-19/cricotracheostomy and control/traditional tracheostomy groups. Body mass index was significantly higher in the COVID-19 group than that in the control group (P = 0.02). The rate of use of anticoagulants was significantly higher in the COVID-19 group compared with the control group (P < 0.01). Peri-operative bleeding, subcutaneous emphysema, and stomal infection rates were not different between the groups, while stomal granulation was significantly less in the COVID-19 group (P = 0.04). CONCLUSIONS: These results suggest that cricotracheostomy is a safe procedure in patients with severe COVID-19.

    OBJECTIVES: Laryngeal complications have been reported after endotracheal intubation and prone positioning in patients with critical coronavirus disease 2019 (COVID-19), but their association is unclear. In this study, we investigated the rate of laryngeal complications in patients with COVID-19 compared to an alternative condition (control group). METHODS: We retrospectively analyzed the data of 40 patients who underwent endotracheal intubation for either COVID-19 or an alternative condition (control group). Data on age, sex, body mass index (BMI), cardiovascular disease (CVD) risk factors, use of prone therapy, duration of endotracheal intubation, and duration from extubation/tracheostomy to laryngeal evaluation were collected from medical records. RESULTS: There were no significant differences in BMI, frequency of CVD risk factors, duration of endotracheal intubation, or duration from extubation/tracheostomy to laryngeal evaluation between the two groups. In the COVID-19 group, all patients adopted the prone position. In comparison, only one patient in the control group adopted the prone position. Significant differences were observed between the two groups regarding the incidence of vocal fold immobility and laryngeal granuloma. CONCLUSION: Laryngeal complications were more common in the COVID-19 group than in the control group. Prone positioning may be a risk factor for these complications. LEVEL OF EVIDENCE: 4.

    PURPOSE: During the perioperative period, coagulofibrinolytic activation occurs, which occasionally results in thromboembolic complications. However, natural perioperative coagulofibrinolytic responses have not been well investigated. The present study examined perioperative coagulofibrinolytic changes and their association with the development of venous thromboembolism (VTE). METHODS: We retrospectively analyzed the changes in coagulofibrinolytic markers for 7 days in 70 patients undergoing elective colorectal surgery. To explore the natural coagulofibrinolytic response, we investigated patients not undergoing perioperative chemical thromboprophylaxis. RESULTS: Coagulation activation occurred from just after surgery to postoperative day (POD) 1, followed by a gradual decrease, but persisted to even POD 7. Fibrinolytic activity showed a tri-phasic response: activation, shutdown and reactivation. Consequently, fibrin/fibrinogen degradation product (FDP) and D-dimer levels continued to increase until POD 7. The development of deep vein thrombosis (DVT) was observed in 11 patients (15.7%). Postoperative sustained hyper-coagulation [soluble fibrin (SF) or thrombin-antithrombin complex (TAT) values on POD 7 > their normal limits] was significantly associated with the development of DVT (SF, p < 0.001; TAT, p = 0.001). CONCLUSION: We found initial coagulation activation and a tri-phasic response of fibrinolytic activity after colorectal surgery. Thus, physicians need to pay attention to these responses when attempting to prevent or treat VTE.

    BACKGROUND: The increasing age of patients with severe motor and intellectual disabilities (SMID) has become a serious concern. Few studies have investigated tumor treatment in this population. METHODS: Tumor treatments for 12 SMID patients were examined. RESULTS: Blood tests and ultrasonography were useful for screening. With regard to treatment, surgery for SMID patients was performed in the same manner as for patients without SMID, and the results were generally satisfactory, without major complications. Typically, cancer was diagnosed at an advanced stage, and many metachronous double cancers were observed. CONCLUSIONS: Treatment yielded satisfactory results for patients with SMID and their families. Future studies should examine the clinical significance of screening and tumor operative method for patients with SMID.

    Indocyanine green (ICG) fluorescence angiography has recently been reported useful as a method for predicting intestinal blood flow and may reduce anastomotic leakage. However, the quantification method for ICG fluorescence angiography has not been established. We usually measure the tissue oxygen saturation (StO2 ) in the intestinal tract via near-infrared spectroscopy, as it is able to measure the oxygen concentration accurately and immediately shows objective data. In this study, we propose that the time to reach the anastomotic site after intravenous ICG injection is an effective parameter for quantifying ICG fluorescence angiography from the comparison to the data of StO2 in the intestinal tract.

    BACKGROUND: We conducted a prospective observational study for investigating the changes in the 13th member of a disintegrin-like and metalloprotease with thrombospondin type 1 motif (ADAMTS13) and its association with the coagulofibrinolytic response in adult trauma patients. METHODS: In 39 trauma patients hospitalized for longer than 7 days, time-course changes in biomarkers of coagulofibrinolysis and systemic inflammation along with ADAMTS13 activity were examined. The patients were stratified into three groups based on ADAMTS13 activities on admission (day 0): normal group (≥70%), mildly decreased group (≥50 and < 70%) and moderately decreased group (< 50%). RESULTS: Among 39 patients with a median Injury Severity Score (ISS) of 20, 11 patients developed disseminated intravascular coagulation (DIC) and 16 patients required transfusion. Six of 39 patients (15.4%) showed moderate decreased ADAMTS13 activity to < 50%, and 20 patients (51.3%) showed mild drops (≥50 and < 70%). These changes in ADAMTS13 activity on day 0 were significantly correlated with changes in IL-6 and other coagulofibrinolytic markers such as platelet counts, prothrombin time and fibrin/fibrinogen degradation product (FDP). Antithrombin activity (AT) and serum albumin (Alb) level showed significantly positive linear correlations with ADAMTS13 activity (AT: r = 0.513, p < 0.001; Alb: r = 0.647, p < 0.001). Simple logistic regression analyses showed that ADAMTS13 activity, if less than 50%, was significantly correlated with the development of DIC (OR 7.499, 95%CI 1.121-49.242, p = 0.038) and the need for transfusion of fresh frozen plasma (OR 9.000, 95%CI 1.327-61.025, p = 0.028). CONCLUSIONS: ADAMTS13 activity decreased even in the early phase of trauma, which was complicated by coagulopathy and systemic inflammation. Furthermore, the decrease in ADAMTS13 activity was correlated with DIC and plasma transfusion.

    INTRODUCTION: It is difficult to use a traction table during surgery for an ipsilateral displaced femoral trochanteric fracture following above-the-knee amputation. However, there are few reports regarding such cases. We describe the simple method we used for positioning the traction table and reducing fracture site during fixation surgery for a displaced femoral trochanteric fracture in this patient following above-the-knee amputation. CASE REPORT: An 80-year-old man was injured in a head-on collision with an oncoming vehicle. We diagnosed him with traumatic gastric perforation, multiple right lower leg fractures, and right lower leg severe crush wound. We performed right above-the-knee amputation and laparoscopic gastrorrhaphy for lifesaving purposes. Thereafter we performed internal fixation for the right femoral trochanteric fracture on the 5th day after the injury. In that operation, we first inserted a 2.4 mm Kirschner wire under fluoroscopic guidance 3 cm proximal to the femoral cut end and attached a horseshoe and traction rope to it. Then, we tightened the rope to the foot piece of the traction table and secured it. Although shortening of the bone fracture was reduced by traction, rotation control was impossible; therefore, the horseshoe was manually controlled through clean sheets during surgery to reduce rotational displacement. We performed internal fixation surgery using a trochanteric femoral nail in the usual manner. CONCLUSION: In the osteosynthesis surgery of displaced femoral trochanteric fractures following above-the-knee amputation, the method of inserting the Kirschner wire at the distal end of the patient's femur and pulling it through the rope enables surgeons to reduce fracture shortening. Reduction of rotational displacement was possible by controlling the horseshoe by hand. In this way, intramedullary nail fixation could be performed without trouble under fluoroscopic guidance.

    Sepsis is a leading cause of mortality in intensive care units due to multi-organ failure caused by dysregulated immune reactions. In this study, kinetic changes in the immune system were analyzed for 72 h in cecal ligation and puncture (CLP)-induced septic mice while preventing animal death by keeping body temperature. Increase of myeloid cells and decrease of B cells in circulation at 6 h after CLP were markedly observed. At the same time point, interleukin (IL)-10 expressing CD5+ regulatory B cells (Bregs) appeared. IL-10 and programmed death-ligand 1 (PD-L1) mRNA as well as IL-1β, IL-6 and interferon γ (IFNγ) mRNA was increased in the spleen at 6 h. A gradual decrease in Bcl-2 and abrupt increase of Bim expression in the spleen at the late phase were also found. These results showed that B lymphocytopenia with the appearance of Bregs is the earliest event, likely leading to immunoparalysis in sepsis.

    We analyzed the Nationwide Registry database on sepsis to examine the effects of an anticoagulation therapy, especially with rh-thrombomodulin (rh-TM) and/or antithrombin (AT) III agent, in septic disseminated intravascular coagulation (DIC) patients. In 3,193 patients enrolled after the exclusion, we investigated the association with in-hospital mortality using Cox proportional hazards models. DIC was diagnosed using the Japanese Association of Acute Medicine (JAAM) and the International Society of Thrombosis and Hemostasis (ISTH) criteria. To analyze the separate treatment effects of rh-TM and/or AT III, we excluded the data of 345 patients treated with all available anticoagulation treatments (rh-TM and/or AT III plus "other anticoagulants": protease inhibitors and heparin/heparinoids). The DIC criterion populations were as follows: JAAM DICs, n = 1,891 and ISTH DICs (overt DIC), n = 1,002. Septic DIC patients were divided into 3 groups: Group 1, no anticoagulation therapy for DIC; Group 2, received rh-TM and/or AT III; and Group 3, received only "other anticoagulants." In JAAM DIC patients, Group 2 did not show an independent association with a reduced risk of in-hospital mortality (hazard ratio [HR]: 0.86; 95% confidence interval [CI]: 0.73-1.01]) as compared with Group 1. However, in ISTH DIC patients, Group 2 showed an inverse association with the risk of in-hospital mortality (HR 0.74; 95% CI: 0.60-0.92) as compared with Group 1, but the same was not true for Group 3 (HR 0.73; 95% CI: 0.47-1.14). The present results support previous findings of the beneficial effects of anticoagulation therapies in septic DIC, also expands the importance of using rh-TM and/or AT agent for septic overt DIC.

    BACKGROUND: Heat stroke induces coagulofibrinolytic activation, which leads to life-threatening disseminated intravascular coagulation (DIC). However, treatment strategies for DIC in heat stroke have not yet been established, and also, the time course changes in coagulofibrinolytic markers have not been thoroughly evaluated. We report a severe heat stroke case with DIC who was eventually saved by anti-DIC treatments in accordance with changes in coagulofibrinolytic markers. CASE PRESENTATION: A 45-year-old man was found unconscious outside, and his body temperature was elevated to 41.9 °C. For heat stroke, we performed an immediate tracheal intubation under the general anesthesia along with cooling by iced gastric lavage, cold fluid administration, and an intravascular cooling using Thermogard™. About 4 h after admission, his core temperature fell to 37 °C. We assessed coagulofibrinolytic biomarkers and treated in accordance with changes in these parameters. This case exhibited a biphasic change varying from an enhanced to a suppressed fibrinolytic type of DIC depending on the relative balance between fibrinolytic activation and the level of plasminogen activator inhibitor-1 (PAI-1). In the early phase with consumption coagulopathy and enhanced fibrinolysis, we transfused a large amount of fresh frozen plasma (FFP) and platelets with tranexamic acid, an antifibrinolytic agent, possibly providing relief for the bleeding tendency. Anticoagulant therapy using recombinant human thrombomodulin-α (rh-TM-α) and antithrombin III (ATIII) concentrate was especially effective for DIC with a suppressed fibrinolytic phenotype in the later phase, after which organ failure that included severe hepatic failure was remarkably improved. CONCLUSION: The present case may indicate the clinical significance of monitoring coagulifibrinolytic changes and the potential benefits of anticoagulants for heat stroke-induced DIC.

    PURPOSE: Screw fixation for unstable pelvic ring fractures is generally performed using the C-arm. However, some studies reported erroneous piercing with screws, nerve injuries, and vessel injuries. Recent studies have reported the efficacy of screw fixations using navigation systems. The purpose of this retrospective study was to investigate the accuracy of screw fixation using the O-arm® imaging system and StealthStation® navigation system for unstable pelvic ring fractures. METHODS: The participants were 10 patients with unstable pelvic ring fractures, who underwent screw fixations using the O-arm StealthStation navigation system (nine cases with iliosacral screw and one case with lateral compression screw). We investigated operation duration, bleeding during operation, the presence of complications during operation, and the presence of cortical bone perforation by the screws based on postoperative CT scan images. We also measured the difference in screw tip positions between intraoperative navigation screen shot images and postoperative CT scan images. RESULTS: The average operation duration was 71 min, average bleeding was 12 ml, and there were no nerve or vessel injuries during the operation. There was no cortical bone perforation by the screws. The average difference between intraoperative navigation images and postoperative CT images was 2.5 ± 0.9 mm, for all 18 screws used in this study. CONCLUSION: Our results suggest that the O-arm StealthStation navigation system provides accurate screw fixation for unstable pelvic ring fractures.

    BACKGROUND: We conducted a prospective observational study for investigating coagulofibrinolytic changes and mechanisms of antithrombin (AT) alternations in trauma. METHODS: Trauma patients hospitalized for more than seven days were analyzed for coagulofibrinolytic biomarkers. The patients were stratified into two groups according to AT activity level on admission (day 0), comprising normal AT and low AT patients. RESULTS: Thirty-nine patients (median Injury Severity Score 20) exhibited initial coagulatory activation and triphasic fibrinolytic changes. AT activity did not show a negative linear correlation with levels of thrombin-antithrombin complex (TAT), a marker of coagulation activity and AT consumption, but was strongly correlated with levels of albumin (Alb), an index of vascular permeability, on day 0 (r = 0.702, p <  0.001). Furthermore, Alb was one of the independent predictors for AT on day 0. IL-6 on day 0 and thrombomodulin (TM) levels during the study period, reflecting systemic inflammation and endothelial cell injury, respectively, were significantly higher in the lower AT group (n = 10) than in the normal group (n = 29) (IL-6, p = 0.004; TM, p = 0.017). On days 2 and 4, TAT levels in the lower AT group were significantly higher than in the normal group. CONCLUSIONS: Trauma caused clear triphasic coagulofibrinolytic changes. Decreased AT in the later phase might lead to a prolonged hypercoagulation. AT reduction in the initial phase of trauma is strongly associated with extravascular leakage as suggested by the association of Alb depletion with IL-6 and TM elevation, but not with AT consumption.

    Case: An increase in cerebrospinal fluid pressure (CSFP) is usually prominent in cryptococcal meningitis, which has a high mortality rate, so aggressive management to control CSFP is crucial. In this case, a 40-year-old-man survived cryptococcal meningitis treated with continuous spinal drainage under bispectral index (BIS) monitoring. He unexpectedly showed hypertension, went into a coma, and even loss his light reflexes due to CSFP elevation. His BIS values had abruptly dropped before developing these symptoms, but dramatically recovered after lumbar puncture drainage, suggesting that BIS monitoring could reflect cerebral function changes due to CSFP alternations. Outcome: Inducing continuous spinal drainage to control CSFP provided stable control of blood pressure and brain activity, which was continuously monitored by BIS, enabling us to provide prompt treatment. Conclusion: Cerebral depressions due to elevated CSFP may suddenly develop, so continuous spinal drainage is needed for preventing catastrophic events. Bispectral index could be useful for detecting early changes from CSFP elevation in meningitis cases with intracranial hypertension.

    BACKGROUND: Reports regarding arthroscopic fixation of the osteochondral fragments for elbow osteochondritis dissecans (OCD) are few. This study assessed the clinical outcomes of arthroscopic fixation of unstable osteochondral fragments by using absorbable pins over a postoperative period of at least 1 year. METHODS: The patients were 13 adolescent baseball players with a mean age of 14 years (range, 12-16 years) who underwent OCD of primary lesions at International Cartilage Repair Society grades III and IV. The patients were evaluated by using validated outcome measures at a mean follow-up period of 24 months (range, 12-50 months). RESULTS: The mean (standard deviation) score in the disability/symptom section of the Disabilities of the Arm, Shoulder, and Hand improved from 12.4 (6.0) before the surgery to 0.5 (1.2) after the surgery, and the sports section improved from 74.5 (25.4) to 1.4 (5.2). The mean (standard deviation) extension improved from -11° (10.8) to -2° (3.9; P < .001). The mean (SD) flexion improved from 129° (11.6) to 137° (5.6; P = .040). All patients were able to resume playing baseball, and 9 (69%) resumed playing at the same position as before their injuries. CONCLUSIONS: The clinical results of arthroscopic osteochondral fragment fixation in the teenaged baseball players with elbow OCD, albeit obtained over only a short period, were favorable. This arthroscopic treatment enables repair of lesions and is considered appropriate for unstable OCD during the adolescent growth spurt.

    CASE REPORT: A 43-year-old male was admitted to a regional hospital after being diagnosed with severe acute pancreatitis. The patient developed a pancreatic abscess with multiple organ failure. He was transferred to our hospital in critical condition. Computed tomography scans revealed enormous pancreatic abscesses expanding from the pancreatic body to the pelvic area. Pigtail catheters were inserted for percutaneous drainage. Even after the drainage, the abscesses did not improve. Percutaneous necrosectomy was performed using a resectoscope through a fistulous tract. After two necrosectomies, the CT scans showed remarkable decreases in the size of the cystic abscesses, and finally, no abscesses were detectable on the 117 th hospital day. CONCLUSION: We herein present the first description of a minimally invasive technique, using resectoscopy, for treating intractable pancreatic abscesses. Future studies are warranted to examine the efficacy and safety of this procedure for difficult cases, as presented in this report.

    A middle age man underwent immediate cardiopulmonary resuscitation (CPR) for ventricular fibrillation (VF) occurred in an ambulance. After arrival in a regional hospital, return of spontaneous circulation (ROSC) was achieved 82 minutes after the collapse. He was in coma even three hours after ROSC. So, he was transferred to our university hospital to receive therapeutic hypothermia (TH). An initial bispectral index (BIS) value suggested a favorable outcome. Thus we decided to aggressive therapies including TH of 34°C for 48 hours, followed by a very slow rewarming at the rate of 1°C per day. Eventually he was discharged from the hospital with good neurological state. This case shows us two points: 1) the importance of the chain of survival: CPR done immediately after the collapse, persistent CPR for refractory VF, followed by coronary interventions after ROSC, continuing care to the university hospital, 2) decision making for TH using BIS monitoring.

    症例は37歳,男性。ベゲタミン-AR配合錠の空包180錠分とともに,自家用車内で深昏睡状態で発見され搬送された。来院時,深昏睡で呼吸循環抑制も伴っており,血中フェノバルビタール濃度は149.04μg/mLであった。人工呼吸管理下に胃洗浄,腸洗浄,尿アルカリ化を図り,呼吸・循環動態は速やかに安定化したものの,血中濃度の低下は乏しかった。第4病日にBIS値が搬入時から持続していた40から緩徐に70〜80へと上昇し,それに伴い意識レベルの改善を認め,第5病日に血中濃度が77.07μg/mLと高値でありながらも,全身状態が安定し,かつ意識清明であったため,人工呼吸器離脱後,気管チューブを抜管した。本症例はベゲタミン-AR配合錠の常用者で,血中濃度と臨床症状の大きな乖離が認められた。一方,BIS値の変化は臨床経過と非常に一致した変化を示し,神経モニタリングとして有用であった。(著者抄録)

    飲食物による咽喉頭および食道熱傷は臨床上、しばしば経験されるが、その報告例は少ない。今回、我々は90℃の高温飲料の摂取後に緊急気道確保を要する咽喉頭熱傷および遅発性瘢痕狭窄を来した食道熱傷の1例を経験したので報告する。症例は28歳の男性。飲酒の席で約90℃のコーヒーを約200ml飲用し、呼吸苦・嚥下痛にて当院受診となった。来院時、上気道粘膜の腫脹が強く、喉頭ファイバーにて喉頭蓋および声帯の腫脹も認め、気道緊急の状態にあり、気管切開による緊急気道確保を行った。咽喉頭熱傷については、経時的に粘膜腫脹は軽快してきたものの喉頭蓋の腫脹が遷延し、容易に誤嚥する状況が続いた。喉頭蓋の腫脹改善とともに第39病日に気管切開チューブを抜去でき、その後も瘢痕形成などは来さなかった。食道熱傷について、受傷早期は食道穿孔等を来さずに経過したが、第25病日に吐血のため、上部消化管内視鏡検査をしたところ、下部食道を中心として食道全長に渡る粘膜の易出血性びらん、潰瘍所見を認めた。第40病日に再度上部消化管内視鏡検査を施行したところ、内視鏡通過は可能であったが、散在性に瘢痕狭窄所見を認めた。粘膜所見は治癒経過にあり、流動食より食事を開始し、第48病日の食道透視検査にて全体的に伸展不良を認めたが、普通食まで摂取可能となったため、第53病日に退院となった。しかしながら、その後も緩徐に食道狭窄は進行し、食道拡張術も奏功せず、第264病日に食道切除術施行となった。温熱熱傷においても、上気道閉塞および遷延する喉頭蓋腫脹に伴う嚥下障害に対する気道管理や、食道瘢痕狭窄に対する経時的な評価、治療が必要である。(著者抄録)

    【はじめに】手術部位感染(SSI)は入院期間の延長や更なる合併症のリスクにもつながるため、SSIの低減は重要課題である。近年、抗菌作用をもつトリクロサンをコートした吸収糸が発売され、当院では2010年8月より開腹手術の体腔内縫合糸および筋膜閉鎖縫合糸を通常の吸収糸(Vicryl)から抗菌縫合糸(Vicryl Plus)へと変更した。【目的】胃癌手術において抗菌縫合糸の使用がSSIの発生予防に有用か否かを検証する。【対象と方法】通常の吸収糸を使用した2009年8月から2010年7月までの胃癌手術症例(Vicryl群)107例と抗菌縫合糸を使用した2010年8月から2011年7月までの胃癌手術症例(Vicryl Plus群)85例とで患者背景やSSI発生率を比較検討した。なお、皮膚切開法、抗菌剤投与、筋膜閉鎖法に関しては両群で差はなかった。【結果】臨床病理学的因子の性別、ASAスコア、BMI、進行度は両群で差はなく、手術因子の出血量、リンパ節郭清にも差はなかった。年齢とSSI risk index、手術時間に関しては、むしろVicryl Plus群で高かった。SSI発生率は、Vicryl群が13例(12.1%)で、Vicryl Plus群が6例(7.05%)であり、両群で統計学的な有意差は検出されなかった。ただし、深部切開創および体腔SSIの発生率に関してはVicryl群で12例(11.2%)、Vicryl Plus群で3例(3.5%)と、Vicryl Plus群で有意に深部・体腔SSIの発生が少なかった(p=0.048)。【まとめ】胃癌手術において、抗菌縫合糸の使用はSSI低減に有用である可能性が示唆された。(著者抄録)

    本研究の目的は, 敗血症病態における免疫反応の動態の解明, 特に未だ詳細な病態が把握されていないBregをはじめとする免疫抑制機構の把握として研究を開始した. これまでに敗血症におけるB細胞の急性期の動態について, マウスCLPモデルを用いて研究を行い, 敗血症早期にBリンパ球減少が起こる中, PD-L1を発現し, IL- 10を産生するBregが増加することを見い出した. Bリンパ球減少による抗体産生低下が起こり, 更にBregによるIL-10産生やPD-L1/PD-1によるTリンパ球, 単球の 免疫抑制が敗血症における免疫抑制病態の重要な要素の一つであることを報告した (Biochem Biophys Res Commun. 2020; 523(1):202-207.). IL-5は腹腔のBリンパ球の維持に関与している. しかし, 敗血症病態におけるIL-5の関与は詳細には知られていない. 現在 IL-5 Venus, KOマウスを用いたCLPによる敗血症病態の腹腔内での免疫反応について検討しているところである. これまでに, IL-5 KOマウスにおいて, WTマウスに比しCLPによる生存率の低下, 細菌処理能の低下を確認した. CLP後の腹腔内においても急激なBリンパ球の低下が見られ, CLP時のTリンパ球やILC-2などCLP時のIL-5産生細胞をいくつか同定した. 今後さらに,肺組織への影響も加え, IL-5の敗血症病態に影響するメカニズムの解明を進め, 治療応用につなげられるように研究を進める予定である.

    8-12週のWistar系雌ラットを用いて、Th12レベルでの脊髄損傷モデルを作成した。損傷作成後直腸温を37℃で1時間維持する群と39℃で1時間維持する群を作成した。脊髄損傷受傷後6、24、48、72時間で損傷脊髄部のTNF-αを抽出しELISA法にて含有量を測定した。また各群でBBBスケールを用いて72時間後の後肢運動機能を評価した。損傷脊髄部のTNF-α含有量はコントロール群に比較して受傷後6時間以降、72時間まで増加していた。TNF-α含有量は直腸温を37℃に維持した群と 39℃に維持した群間では有意な差は認められなかった。また後肢運動機能も両群間で有意な差は認められなかった。

    本研究は急性病態における血液凝固線溶動態を解明し、その治療応用を目的としている。今回、急性病態下にある患者血液で、凝固線溶系マーカー及び炎症・血管内皮細胞障害関連の各種マーカーを解析した。急性病態において、ほぼ同様に侵襲に伴う凝固亢進やt-PAやPAI-1による線溶亢進から抑制への変化などの血液凝固線溶動態を捉えた。特に熱中症や腹膜炎に伴うDICに関しては、凝固線溶動態を指標とした治療戦略・効果判定が有用であった。更に、これらの凝固線溶異常と血管内皮細胞障害との関連を明らかにした。今回の結果は、DICなどの凝固線溶異常の病態解明と治療戦略構築に必須なものであると考えられる。
