Comparison of perioperative outcomes between laparoscopic and open pancreaticoduodenectomy: a single-center retrospective study / 中华肝胆外科杂志

ABSTRACT

Objective:This study aimed to compare the clinical outcomes of laparoscopic pancreaticoduodenectomy (LPD) versus open pancreaticoduodenectomy (OPD).Methods:The clinical data of 386 patients who successfully underwent pancreaticoduodenectomy at the People's Hospital of Zhengzhou University from June 2017 to December 2019 were retrospectively analyzed. According to the different surgical methods, patients were divided into the LPD group ( n=122) and the OPD group ( n=264). The differences in operation time, intraoperative blood loss, postoperative hospital stay, postoperative complications, postoperative oncology survival outcomes and prognosis between groups were compared. Results:Of 386 patients in this study, there were 232 males and 154 females, aged (57.8±11.0) years. The operation time of the LPD group was (330.69±80.55) min which was significantly longer than that of the OPD group (241.13±77.24) min. The intraoperative blood loss 300.00(200.00, 400.00) ml was also significantly less than the OPD group 400.00(262.50, 500.00) ml, and the length of postoperative stay in the LPD group (12.21±5.24) d was significantly less than the OPD group (16.61±6.63) d, (all P<0.05). There were 36 patients (29.51%) in the LPD group and 81 patients (30.68%) in the OPD group who developed postoperative complications, with no significant difference between groups ( P>0.05). Postoperative oncology outcomes showed that the number of lymph nodes dissected in the LPD group was significantly more than that in the OPD group [(12.65±5.03) vs (10.07±5.09)], ( P<0.05). There were no significant differences between the two groups in tumor pathology type, size, degree of differentiation and R 0 resection rates (all P>0.05). All patients were followed up for 6-36 months, with a median follow-up of 20 months. The survival rates of patients with malignant tumors after following-up for more than 1 year in the LPD group was 84.72%(61/72), that in the OPD group was 85.81%(133/155), with no significant difference between groups ( P>0.05). Conclusion:LPD was safe and feasible with its advantages of minimally invasiveness.
