Background/aims: A new method of reconstructing the pancreatic stump after pancreatoduodenectomy (PD) is necessary to improve the postoperative mortality rate. Thus, we modified the pancreatoenteric procedure to reduce anastomotic leakage from the pancreatic stump after PD, and we conducted a study to evaluate the usefulness of the new procedure on the basis of patients' postoperative condition.
Methodology: We compared the postoperative condition of 21 patients who underwent PD with the new separated loop (SL) reconstruction (6 men, 11 women; mean age, 67.7+/-7.2 years) to that of 31 patients (12 men, 19 women; mean age, 66.8+/-10.3 years) who underwent PD with pancreatogastrostomy (PG). In the SL reconstruction procedure, the proximal jejunum is brought up behind the colon, and an end-to-side choledochojejunostomy is made with a single layer of interrupted sutures. Approximately 20cm of the jejunum is fitted with a fixed stomach tube for postoperative enteral feeding, and the cut proximal jejunum is positioned next to the pancreatic stump. A pancreatic tube is inserted into the lumen of the pancreatic duct and fixed without closing the pancreatic duct. Pancreatojejunostomy is achieved as an end-to-end anastomosis with the pancreatic stump telescoping into the proximal jejunum. Approximately 20cm of the jejunum is anastomosed side-to-end to the stomach, and end-to-side jejunojejunostomy is made to complete a Y-type reconstruction. Each patient's postoperative condition was also assessed on the basis of serum albumin (ALB), cholinesterase and total cholesterol (T-CHO) levels on postoperative days (PODs) 14 and 28.
Results: A high level of amylase in drainage fluid was noted in two (6.5%) and delayed gastric emptying in four (12.9%) of the patients in the PG group. There were no complications in the SL group. Postoperative levels of ALB on POD 14 and T-CHO on POD 28 were significantly higher than in the PG group.
Conclusions: The SL method is safe and does not induce complications after PD. Our results indicate that this method may provide a favored outcome.

The Arc of Bühler (AoB) is a rare anatomical variant in gastrointestinal vasculature where there is an aberrant anastomotic vessel between coeliac and superior mesenteric arteries. We present a rare case where AoB was noted intraoperatively to have haemodynamically significant flow in the context of coeliac artery stenosis, supplementing arterial supply to the hepatic artery proper via the gastroduodenal artery (GDA). An interpositional jump graft between the aorta and the GDA stump was created using the long saphenous vein, and flow was restored.

Background: The long-term survival rate of patients with pancreatic ductal adenocarcinoma has improved alongside the development of multidisciplinary treatment, and there is now demand for less invasive surgery that maintains postoperative pancreatic function. We evaluated the efficacy of pancreas-preserving distal pancreatectomy in terms of oncologic parameters and postoperative pancreatic function.
Methods: The data of 98 consecutive patients who underwent distal pancreatectomy for the treatment of pancreatic ductal adenocarcinoma between 2012 and 2022 in our institution were retrospectively analyzed.

Background: Consensus on the nomenclature and indications for reoperation for post-operative pancreatic fistula (POPF) after pancreatoduodenectomy (PD) is lacking. This study explores the available literature to classify the different types of reoperations and report outcomes.
Methods: A systematic literature search was performed, including articles from 2010 to 2024 reporting reoperations for POPF after PD.

Objectives: Choledochal cyst excision (CDCE) with hepaticojejunostomy is standard of care in choledochal cysts. Complications related to inadequate healing of distal stump like post-operative pancreatic fistula (POPF) and bleeds have not been addressed in literature. We report two decade experience with these complications following CDCE.

Background: Gallbladder cancer is a malignancy with a highly dismal prognosis, requiring optimal surgical strategies to achieve effective outcomes. We aimed to evaluate the outcomes of our algorithm-based decision-making approach based on image T-factors and intraoperative pathology of regional lymph node metastases and the bile duct stumps in patients undergoing gallbladder cancer resection.
Methods: A prospectively maintained database of patients who underwent gallbladder cancer resection between April 2001 and June 2022 was reviewed.
