However, a few studies have explored central pancreatectomy (CP) for non-reconstructed small remnant pancreases after PD. This study presents a case of CP without pancreatic reconstruction after PD. A 58-year-old man with cerebral palsy underwent PD for distal cholangiocarcinoma. Three years postoperatively, a 12-mm tumor was detected in the remnant pancreatic body and diagnosed as a pancreatic neuroendocrine neoplasm. Surgical resection was performed, because the tumor was enlarged and chemotherapy resistant. The afferent loop with pancreatojejunostomy anastomosis was dissected, and CP, including pancreatojejunostomy anastomosis, was performed. Given the remnant pancreas was hard and atrophic, the pancreatic tail was transected using a stapler without reconstructing the small remnant pancreas. The patient experienced no postoperative complications including postoperative pancreatic fistula, and the endocrine function of the pancreas was preserved. We present a case of remnant pancreatic CP that did not require reconstruction after PD. Preservation of the small remnant pancreas without reconstruction during CP may be feasible to maintain endocrine function in select patients after PD.","PeriodicalId":22096,"journal":{"name":"Surgical Case Reports","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2024-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142216625","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The diagnosis of PL requires a thorough medical history of laparoscopic myomectomies using a morcellator and the identification of typical magnetic resonance imaging (MRI) findings as uterine fibroids. Imaging diagnosis of PL is occasionally difficult when PL degenerates in various ways, owing to atypical findings on computed tomography (CT) and MRI. A 29-year-old woman with a history of laparoscopic myomectomy visited a local hospital with lower abdominal pain. A mesenteric tumor on the sigmoid mesentery was suspected on MRI, and she was referred to our hospital. CT scan showed strong early contrast uptake in the center of the tumor, and MRI T2-weighted images showed high signals at the tumor margins and low signals in the center, suggesting a schwannoma. PL was also part of the differential diagnosis because of the patient’s history of laparoscopic myomectomy. With a preoperative diagnosis of a sigmoid colon mesenteric tumor undeniably of malignant origin, laparoscopic resection of the sigmoid mesenteric tumor was performed. Histopathological examination revealed it to be a PL. We report a case of PL of the sigmoid mesentery with schwannoma-like findings on imaging that was treated laparoscopically. PL is sometimes difficult to distinguish from schwannomas because of the variety of imaging findings, such as uterine fibroids. PL should be considered in the differential diagnosis of mesenteric tumors following laparoscopic myomectomies, even if it does not show typical imaging findings, such as uterine fibroids.","PeriodicalId":22096,"journal":{"name":"Surgical Case Reports","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2024-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142216627","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
