Background/aims: Total pancreatectomy is rarely performed as the treatment of pancreatic carcinoma because of markedly impaired quality of life and poor prognosis. Intraductal papillary-mucinous tumor (IPMT) of the pancreas is characterized by extensive intraductal spread and favorable outcome even in its invasive stage. The role of total pancreatectomy was reappraised in the treatment of IPMT.
Methodology: A total of five Japanese patients with IPMT underwent total pancreatectomy and their clinical follow-up data were reviewed.
Results: Total pancreatectomy was performed due to massive involvement of the entire pancreas in two patients, positive surgical margins on frozen section in one, benign IPMT with concomitant pancreatic cancers in one and recurrent IPMT in the remnant pancreas after distal pancreatectomy for IPMT in the other. Three of them underwent total pancreatectomy of the Whipple type, another underwent total gastrectomy and the other underwent the pylorus-preserving method. Surgical margins were negative by histology and no lymph node metastases were evident. Two patients had severe infection including liver abscess in one and pneumonia in the other. The former died on postoperative day 82 and the latter was controlled by medical treatment and discharged on postoperative day 73. The other three patients had an uneventful postoperative course and were discharged from 29 to 62 days after the operation. Long-term follow-up of the four patients revealed that three patients had hypoglycemic attacks, two diabetic retinopathy and two fatty liver. The four patients were doing well from 683 to 4,140 days after the operation without signs of recurrence.
Conclusions: Total pancreatectomy would be indicated as a treatment of benign or malignant IPMT with extensive involvement when patients' condition permits and gives a chance of cure, although careful long-term medical care and follow-up are essential.

Background: Pancreatic ductal adenocarcinoma (PDAC) typically occurs in an older patient population. Yet, early-onset pancreatic cancer (EOPC) has one of the fastest growing incidence rates. This study investigated the influence of age and tumor location on postoperative morbidity and mortality in a large, real-world dataset.

Objectives: To evaluate the effects of postoperative pancreatic enzyme replacement therapy on fat digestion and absorption in patients following initial total pancreatectomy.
Methods: Data were retrospectively collected from patients who underwent initial total pancreatectomy at our department between 2012 and 2020. Fat digestion, absorption functions, serum nutritional markers, HbA1c levels, and hepatic steatosis before and after the initial total pancreatectomy were evaluated.

Article Synopsis
- The study examines the effects of intraoperative corticosteroids on postoperative complications in patients undergoing pancreatoduodenectomy (PD), finding no significant improvement in major complications or specific issues like pancreatic fistulas or infections.
- A meta-analysis of 5 studies involving 1,449 patients revealed no difference in outcomes between those who received corticosteroids and those who did not across various complications measured.
- The conclusion suggests that corticosteroids do not provide a protective advantage in this surgical context, emphasizing the need for further clinical trials to gather more robust evidence.

Introduction: Individuals with mental illness are at risk for poor surgical outcomes. Notably, the impact of preoperative assessment and optimization for high-risk surgical procedures remains a relatively understudied and evolving field. We sought to investigate the association between mental health assessment and postoperative outcomes.

Objective: The aim was to evaluate the sustainability of the pancreatic Enhanced Recovery After Surgery (ERAS) program and the effect of ERAS items on patient morbidity and hospital stay.
Background: The current ERAS guideline recommendations encompass 27 items to improve recovery after pancreatoduodenectomy (PD).
Methods: Patients who underwent pancreatic resection at the University Hospital Hamburg-Eppendorf between February 2016 and June 2023 were included.
