Perioperative Outcomes and Long-Term Survival of Laparoscopic Pancreaticoduodenectomy: A Retrospective Study of 653 Cases in a Single Institution

Introduction: Laparoscopic pancreaticoduodenectomy (LPD) is gaining wide acceptance within pancreatic surgery. However, longitudinal data are lacking. The aim of this study was to analyze and assess the short-term outcomes and long-term survival of LPD over a duration of 8 years. Methods: Patients who underwent LPD in our institution between November 2013 and September 2021 were included in this study. The perioperative outcomes were statistically analyzed. The long-term survival was studied over a median follow-up duration of 13 months. Results: In total, 653 consecutive patients treated at our institution were included, of which 617 cases underwent standard LPD and 36 cases underwent LPD with vascular resection. The rate of death in hospital, reoperation, postpancreatectomy hemorrhage, postoperative pancreatic fistula, and delayed gastric emptying were 4.4%, 10.3%, 11.9%, 12.9%, and 6.1% respectively. There were statistical differences in the intraoperative blood loss and transfusion, operation time, and the R0 resection rate between the LPD cases and LPD with vascular resection cases. A total of 526 cases were pathologically diagnosed of cancer. The 1-, 3-, and 5-year survival rates were 49.2%, 17.9%, and 17.9%, respectively, for pancreatic cancer with the median survival time of 12 months. The 1-, 3-, and 5-year survival rates were 76.9%, 60.8%, and 52.5%, respectively, for bile duct cancer with the median survival time of 35 months. The 1-, 3-, and 5-year survival rates were 80.2%, 62.2%, and 52.9%, respectively, for duodenal cancer with the median survival time of 53 months. The 1-, 3-, and 5-year survival rates were 72.5%, 54.5%, and 50%, respectively, for ampullary cancer with the median survival time of 55 months. Conclusion: LPD is a feasible and oncologically acceptable procedure with satisfying perioperative outcomes and long-term survival in a high-volume institution.
