Abstract

Introduction:Fishbone (FB) ingestion is a rare cause of gastrointestinal perforation. Herein, we report a case of FB-induced colonic perforation, in which the presence of a penile colonic carcinoma may have contributed to the development of the perforation. Case Presentation:An 83-year-old man was admitted to our hospital with severe abdominal pain during bowel movement. Computed tomography (CT) yielded a diagnosis of sigmoid colonic perforation due to FB and secondary peritonitis. Preoperative endoscopic examination suggested that the perforation was associated with a stalked colon tumor in the vicinity. After undergoing low anterior resection and sigmoid colostomy, the patient is currently doing well. Conclusion:The incidence of FB-induced colorectal-cancer-related perforation is expected to increase in the future owing to an aging society, the increase in the rates of colorectal cancer, and increase in fish consumption. This rare case suggests that preoperative examinations are important and that even relatively small polyps can contribute to gastrointestinal perforation caused by FBs. Older individuals should exercise caution during fish ingestion.

Abstract

Background Hepatectomy has a high risk of perioperative bleeding due to the underlying disease. Here, we investigated the postoperative impact of allogeneic blood transfusion during hepatectomy.Methods The surgical outcomes in 385 patients who underwent hepatic resection for hepatocellular carcinoma were retrospectively reviewed. The association of allogeneic blood transfusion with surgical outcomes and remnant liver regeneration data was analyzed.Results Eighty-six patients (24.0%) received an allogeneic blood transfusion and 272 patients (76.0%) did not. After propensity score matching, the incidence rates of postoperative complication (Clavien-Dindo grade >IIIA), posthepatectomy liver failure, and massive ascites were significantly higher for the group that received a blood transfusion than for the group that did not receive blood transfusion (P< .001, P= .001, and <.001, respectively). Postoperative measures of total bilirubin, albumin, platelet count, prothrombin time, aspartate aminotransferase, and alanine aminotransferase were significantly more favorable in patients without blood transfusion until day 7 after surgery. There were no correlations in the remnant liver regeneration at 7 days, and 1, 2, 5, and 12 months postoperatively between the 2 groups (P= .585, .383, .507, .261, and .430, respectively). Regarding prognosis, there was no significant difference in overall and recurrence-free survival between the 2 groups (P= .065 and .166, respectively).Conclusion Allogeneic transfusion during hepatectomy strongly affected remnant liver function in the early postoperative period; however, this was not related to the remnant liver regeneration volume. Despite that the allogeneic transfusion resulted in poorer postoperative laboratory test results and increased postoperative complication and mortality rates, it had no effect on the long-term prognosis.

Abstract

Background/aims: The natural history of pancreatic branch duct-type intraductal papillary mucinous neoplasms (BD-IPMNs) is still unknown. This retrospective study aims to determine the morphological changes of BD-IPMNs with attention to the history of surgical resection for extrapancreatic malignancies. Methods and materials: This study included 427 subjects with BD-IPMN at the Osaka Medical College from January 2001 to December 2019; 134 patients were included. The predictive factors for the progression of BD-IPMN based on morphological changes were evaluated by univariate as well as multivariate analyses. Furthermore, the clinical features of BD-IPMNs with progressive lesions during follow-up were investigated. Results: The average interval of follow-up was 35.8 months (with a range between 12.1 and 157 months). Disease progression occurred in 6 subjects (4.5%). In two of them (1.5%), IPMN-related invasive carcinoma was found. Multivariate analysis demonstrated that surgical resection for extrapancreatic malignancies was a significant predictor of BD-IPMN progression. Conclusion: The history of resection of extrapancreatic malignancies should be considered during the follow-up of BD-IPMN.
