Background: Previous retrospective studies have demonstrated the effectiveness of parenchymal pre-compression in reducing pancreatic fistula after left-sided pancreatic resection; however, no multicentre RCT has been conducted. The aim of this study was to investigate whether pre-compression reduces grade B/C pancreatic fistula after left-sided pancreatic resection.
Methods: Between 23 March 2021 and 26 January 2023, patients scheduled for left-sided pancreatic resection were enrolled in a multicentre RCT at 13 hospitals in Japan. These patients were randomly assigned (1 : 1) to the pre-compression group or the non-compression group. The primary endpoint was the incidence of grade B/C pancreatic fistula and the secondary endpoint was it in the subgroup.
Results: Overall, 180 patients were assigned to the pre-compression group and the non-compression group (92 patients and 88 patients respectively) and 171 patients were analysed (88 patients in the pre-compression group and 83 patients in the non-compression group). Grade B/C pancreatic fistula was observed in 22 patients (12.9%), including 11 of 88 patients (12.5%) in the pre-compression group and 11 of 83 patients (13.3%) in the non-compression group (OR 0.94 (95% c.i. 0.38 to 2.31); P = 0.883).
Conclusion: A statistically significant difference in the incidence of grade B/C pancreatic fistula was not observed between the pre-compression group and the non-compression group.

Background: The International Study Group of Pancreatic Surgery has established the definition and grading system for postpancreatectomy acute pancreatitis (PPAP). There are no established machine learning models for predicting PPAP following pancreaticoduodenectomy (PD).
Aim: To explore the predictive model of PPAP, and test its predictive efficacy to guide the clinical work.

Background: Gastric cancer is the most common malignancy of the digestive system and surgical resection is the primary treatment. Advances in surgical technology have reduced the risk of complications after radical gastrectomy; however, post-surgical pancreatic fistula remain a serious issue. These fistulas can lead to abdominal infections, anastomotic leakage, increased costs, and pain; thus, early diagnosis and prevention are crucial for a better prognosis.
