Research progress in the selection of pancreaticojejunostomy suture in pancreaticoduodenec-tomy

Pancreaticoduodenectomy (PD) is the mainstay of treatment for periampullary space‑occupying disease. The occurrence of pancreatic fistula after PD is still an unsolved clinical problem, which seriously affects the safety of surgery. Various methods have been reported in clinical practice to reduce the incidence of pancreatic fistula, such as improving pancreaticoenteric anastomosis, using biological sealants, applying somatostatin analogs, and continuous peritoneal irrigation, etc., but the incidence of pancreatic fistula remains at 5%-30%. There are many risk factors related to pancreatic fistula after PD, in which reasonable selection of suture materials is an important factor and also an important factor affecting the curative effect of surgery. The authors analyze the characteristics and shortcomings of various sutures used in PD, in order to provide help to improve the safety of surgery and reduce the incidence of pancreatic fistula after PD.
