Abstract: Objective To investigate the clinical feasibility and safety of the method of external pancreatic duct drainage in laparoscopic pancreaticoduodenectomy(LPD).Results The clinical data of 13 patients with LPD who underwent external pancreatic duct drainage at the Jingzhou Hospital Affiliated to Yangtze University from December 2021 to December 2022 were retrospectively analyzed.The surgical process and postoperative complications of the patients participating in this study were observed,and the clinical effect of external pancreatic duct drainage on improving various postoperative complications in patients with LPD were analyzed.Results All the 13 patients underwent laparoscopic surgery successfully and discharged from the hospital smoothly.The incidence of postoperative biochemical fistula was 15.38% (2/13).No complications of grade B and above pancreatic fistula and intraperitoneal hemorrhage occurred.The average postoperative hospital stay was (14±8.5) d,reoperation and mortality within 30 days after operation were 0.Conclusion External pancreatic duct drainage can effectively improve the occurrence of postoperative complications such as pancreatic fistula and hemorrhage in patients with LPD,and improve the safety of perioperative surgery,and is especially suitable for the early stage of LPD low-volume operation center.
