Context: Total pancreatectomy with islet autotransplantation (TPIAT) is a definitive management for intractable pain in patients with chronic pancreatitis (CP). Islet autotransplantation (IAT) allows for the preservation of beta cells to prevent complications of long-term diabetes.
Objective: Our study follows TPIAT recipients for up to 12 years to determine the efficacy of the procedure completed with an off-site islet isolation facility.
Methods: Patient demographics, mixed meal tolerance test measures, glycosylated hemoglobin, insulin requirements, and homeostatic model assessment for insulin resistance values were collected prior to surgery and at the most recent follow-up assessment.
Results: Forty-four patients (median age, 46.0 years; range, 20-78 years) underwent TPIAT for CP. At an overall median follow-up time of 845.5 days (range, 195-4470 days) 8 patients were insulin independent and 36 patients were insulin dependent. At the most recent follow-up time point, islet yield per kilogram was the strongest indicator of insulin independence. Homeostatic model assessment for insulin resistance values were comparable between insulin independent and dependent cohorts.
Conclusions: Our long-term follow-up data suggest that IAT can effectively reduce insulin requirements and improve postoperative glycemic control.

Prepancreatic postduodenal portal vein discovered in a pediatric patient undergoing total pancreatectomy with islet autotransplantation: a case report and review of literature.

Department of Abdominal Transplant and Hepatopancreatobiliary Surgery, Nationwide Children's Hospital, Columbus, OH, United States.
Background: Prepancreatic postduodenal portal vein (PPPV) is a rare anatomic variant where the portal vein (PV) runs anterior to the pancreas and posterior to the duodenum. Only 20 cases of PPPV, all in adults, have been reported in literature. We report the first case of PPPV in a pediatric patient discovered intraoperatively during total pancreatectomy with islet autotransplantation (TPIAT) and the third known case in which the PPPV could be isolated intraoperatively.

Background: Pancreatic resections for pancreatic neuroendocrine tumors (pNET) may experience a higher complication rate than for pancreatic ductal adenocarcinoma (PDAC). This study aimed to determine the rate of the novel composite "Ideal Outcome" measure after resection for pNET, using PDAC as reference.
Methods: This observational cohort study included all consecutive patients after pancreatic resection for pNET and PDAC using the nationwide Dutch Pancreatic Cancer Audit (2014-2021).

Background: Post-pancreatectomy acute pancreatitis (PPAP) is an early acute inflammatory process of the pancreatic remnant that is associated with a series of downstream pancreas-specific complications. This study aimed to investigate the relationship between postoperative serum C-reactive protein (CRP) levels and the occurrence of PPAP after pancreaticoduodenectomy (PD).
Methods: Consecutive patients who underwent PD between January 1, 2020, and May 31, 2022, were retrospectively analyzed.
Total Pancreatectomy for Locally Advanced Pancreatic Adenocarcinoma with Coeliac Trunk Resection and Retrograde Gastric Revascularization Through Aorto-Hepato-Spleno Allograft.

Department of HPB Surgery and Liver Transplantation, Hôpital Beaujon, Assistance Publique-Hôpitaux de Paris (AP-HP), Université de Paris-Cité, Clichy, France.
Background: Locally advanced pancreatic adenocarcinomas (LA-PDAC) are more frequently operated now than in the past because of new regimen chemotherapy and improvement in surgical technique. Resection of the coeliac trunk (CT) during pancreatoduodenectomy (PD) or total pancreatectomy (TP) is not routinely done owing to the risk of liver and gastric ischaemia. In this video, a patient with LA-PDAC underwent TP with CT resection and retrograde gastric revascularization through the distal splenic artery.

Background: Delayed gastric emptying (DGE) is a frequent complication of pancreatoduodenectomy (PD) and is associated with prolonged hospital stay, readmission, increased hospital costs and decreased quality of life. However, the pathophysiology of DGE remains unclear.
Methods: This is a retrospective study of patients who underwent PD for pancreatic or periampullary tumours.
