RESUMO

BACKGROUND: Several large-scale studies have assessed endovascular and surgical treatment methods for nonocclusive mesenteric ischemia (NOMI); however, the prognostic factors for NOMI remain unclear. Therefore, this study aimed to evaluate risk factors for in-hospital mortality among patients with NOMI who underwent laparotomy and to examine therapeutic strategies that may improve the prognosis. MATERIALS AND METHODS: In this multicenter retrospective study, the authors reviewed the electronic medical records retrieved from the inpatient database of patients with NOMI at eight district general hospitals between January 2011 and January 2021. A total of 88 patients who underwent laparotomies were divided into survivor and nonsurvivor groups, and statistical analysis was performed to determine clinical and physiological factors. RESULTS: Exploratory laparotomy based on second-look surgery was the first treatment choice. The overall mortality rate was 48.8%, with a male-to-female ratio of 1.1:1. The median Sequential Organ Failure Assessment (SOFA) score was 8 [interquartile range: 3.75-14.2], and the median SOFA scores were 5 [3-7] in the survivor group and 13 [9-17.5] in the nonsurvivor group. Univariate analysis revealed a significant difference in BMI ( P <0.001), hypoglycemia ( P =0.0012), previous cardiovascular surgery ( P =0.0019), catecholamine use ( P <0.001), SOFA score ( P <0.001), platelet count ( P =0.0023), and lactate level ( P <0.001). Logistic regression analysis using the factors with significant differences revealed that SOFA score ≥10 (odds ratio 23.3; 95% CI: 1.94-280.00; P =0.013) was an independent prognostic factor. In addition, catecholamine use was suggested as a factor with a SOFA score greater than or equal to 10. CONCLUSION: This study confirmed that a SOFA score of greater than or equal to 10 may be associated with increased mortality. While closely monitoring low blood pressure and renal dysfunction, survival rates may be improved if surgical intervention is performed before the SOFA score reaches greater than or equal to 10.

RESUMO

Development of acquired factor V (FV) inhibitor is a rare coagulation disorder. Production of heteroantibodies against bovine FV, a contaminant in fibrin tissue adhesives, is a common cause of this condition in the field of surgery. The development of recombinant thrombin eliminated contamination of bovine FV, and infrequent use of bovine thrombin has decreased the risk of FV inhibitor development. Here, we report the case of a 43-year-old man who had marked prolongation of prothrombin time and activated partial thromboplastin time after surgery. Mixing coagulation studies with normal plasma and patient's plasma suggested the presence of an inhibitor. Clotting factor assays revealed that FV activity decreased to <1% with positive FV inhibitor titer (9.2 Bethesda units). The diagnosis of the FV inhibitor was confirmed. Overt bleeding was not observed during the course of hospitalization. His coagulation abnormalities rapidly normalized without any medical intervention. A careful review of his medical records revealed that no tissue adhesives were used in the patient, and the FV inhibitor would likely be autoantibodies. Antibiotic use during the perioperative period or the surgical procedure itself may trigger the occurrence of FV inhibitors. This case highlights that FV inhibitor may develop after the surgical procedure even without a history of the use of fibrin tissue adhesives. Surgeons and hematologists should be aware that this rare but potentially life-threatening condition may occur after the surgical procedure.

RESUMO

Appendiceal intussusception is an uncommon pathologic condition. We report herein a case of appendiceal intussusception induced by appendiceal carcinoma. A 76-year-old woman was admitted to hospital because of epigastric pain. CT scan showed multiple concentric ring sign in ascending colon and enhanced tumor in transverse colon. Colonoscopy showed invagination of polypoid lesion which was pushed back to cecum endoscopically. Laparoscopy-assisted ileocecal resection with regional lymph node dissection was performed for cecal cancer. During surgery, the appendix was found to be inverted completely into the cecum. The tumor was 70×35 mm in size in the cecal cavity, and the appendix had completely invaginated into the cecum at its base. Histopathologic examination revealed early appendiceal carcinoma. The patient is healthy without recurrence.

RESUMO

A 76-year-old man visited our hospital with complaints of appetite loss and diarrhea. Abdominal computed tomography (CT)showed a large transverse colon tumor at the splenic flexure and a gastrocolic fistula. Upper gastrointestinal series and gastroscopy demonstrated a type 2 tumor in the transverse colon and a gastrocolic fistula as the scope was inserted into the transverse colon. Colonoscopy showed a type 2 tumor of the rectum. Based on the diagnosis of advanced transverse colon cancer with gastrocolic fistula and synchronous rectal cancer, a one-stage curative operation was performed. Pathologically, both cancers were well-differentiated adenocarcinomas, but the transvers colon cancer was partially mucinous. Lymph node metastasis was absent. Gastrocolic fistula complicating colon cancer is rare, to our knowledge, with only 29 cases reported in Japan. A curative operation was performed in 73%of these cases, including ours, and lymph node metastasis was observed in only 22%. This suggests that colon cancer with a gastrocolic fistula might undergo less lymph node metastasis despite increased invasion depth, and that a curative operation for the colon cancer and gastrocolic fistula should be considered.
