Despite the continuous progress of surgical techniques, the optimization of pancreatic duct drainage remains a key factor in improving surgical success rates and reducing complications. Pancreatic fistula, as the most common and most serious complication after pancreaticoduodenectomy, has a significant impact on patient prognosis and quality of life.
