ABSTRACT
With the rapid development of laparoscopic techniques, the safety of laparoscopic surgery has gradually been recognized. Its advantages, including clear visualization, minimal trauma and faster recovery, are increasingly favored by surgeons and patients. Common postoperative complications of laparoscopic pancreaticoduodenectomy include pancreatic fistula, bleeding, gastric paresis, pancreatic insufficiency, and wound infection. Among them, postoperative pancreatic fistula and its related complications are the leading causes of mortality after laparoscopic pancreaticoduodenectomy. This article present an overview of the understanding of postoperative pancreatic fistula, combined with recent research progress in this field, to explore the potential mechanisms of pancreatic fistula occurrence and development, and also summarize the predictive models for postoperative pancreatic fistula and discuss the future trends in laparoscopic pancreaticoduodenectomy.
