In recent years, with the continuous development of minimally invasive techniques, laparoscopic pancreatic surgery has also been widely used. Although the postoperative mortality rate of laparoscopic pancreatic surgery has been decreasing as the technology continues to improve and mature, the complication rate reported varies widely among centers.The definition and grading criteria of ISGPS on postoperative complications of pancreatic surgery are mostly proposed based on open pancreatic surgery, and most of the data of the later related studies are also for open pancreatic surgery, while the applicability of the definition and grading criteria in laparoscopic pancreatic surgery is still lacking in systematic The study The main purpose of this study is to investigate the applicability of the ISGPS definition and grading criteria for pancreatic fistula, postoperative bleeding and delayed gastric emptying in laparoscopic pancreatic surgery.
