Single-center clinical analysis of laparoscopic pancreaticoduodenectomy and laparoscopic total pancreatectomy for treating pancreatic cancer / 中华胰腺病杂志

ABSTRACT

Objective:To analyze the safety and therapeutic efficacy of laparoscopic pancreaticoduodenectomy (LPD) and laparoscopic total pancreatectomy (LTP) in the treatment of pancreatic cancer.Methods:Clinical data of 87 patients with pancreatic head and neck cancer who underwent LPD or LTP in the Department of General Surgery at Peking Union Medical College Hospital from December 2018 to August 2023 were retrospectively analyzed. The surgical approach, operative time, intraoperative blood loss volume, conversion rate to open surgery, perioperative mortality, re-operative rate, rate of major postoperative complications, postoperative hospital stay, number of lymph nodes harvested, tumor pathological stage, R 0 resection rate, initiation of postoperative chemotherapy and survival outcomes were recorded. The follow-up period extended until September 2023. Results:Among the 87 patients, 78(89.7%) underwent LPD and 9(10.3%) underwent LTP. PV-SMV vascular resection and reconstruction was performed in 16 cases (18.4%), and 11 cases totally underwent laparoscopy. Five cases (5.7%) required conversion to open surgery. The mean operative time was 279.8±74.0 minutes, and the mean intraoperative blood loss volume was 520.1±743.2 ml. The overall length of hospital stay was 15.9±6.3 days, with a mean postoperative hospital stay of 11.5±6.0 days. The rate of major postoperative complications was 19.5%, including 4 cases (4.6%) of postoperative bile leakage, 6 cases (6.9%) of postoperative gastric emptying disorders, and 3 cases (3.4%) of postoperative bleeding. There was one case (1.1%) with secondary surgery and one case (1.1%) with perioperative death. Among LPD patients, 5 cases (6.4%) had postoperative grade B or higher pancreatic fistula. Advanced age (≥70 years) did not increase the incidence of perioperative complications. All patients achieved R 0 resection. The mean number of lymph nodes harvested was 25.9±11.4. The median time to initiation of postoperative chemotherapy was 2.13±1.43 months. The median overall survival was 16 months. Conclusions:In a high-volume center for pancreatic diseases, LPD and LTP are safe and feasible for the treatment of pancreatic cancer, which could achieve satisfactory anti-tumor efficacy and improve patients' prognosis.
