Minimally invasive (laparoscopic and robot-assisted) versus open approach for central pancreatectomies: a single-center experience

Abstract

Background There continues to be an interest in minimally invasive approaches to pancreatic surgery. At our institution, there has been a progressive change from an open to minimally invasive surgery (MIS) (laparoscopic, robotic, or laparoscopic-robotic) approach for central pancreatectomies (CP). The aim of this study was to evaluate surgical outcomes with open CP (O-CP) versus minimally invasive CP (MI-CP). Methods A retrospective medical review of patients who underwent CP between 1993 and 2018 at Yonsei University Health System, Seoul, Korea was performed. Short-term perioperative outcomes were compared between O-CP and MI-CP. Results Thirty-one CPs (11 open, 20 MIS) were identified during the study period. No difference was observed in admission days between O-CP and MI-CP (21.2 vs. 16.7 days, p = 0.340), although operating time was significantly increased in the MI-CP group (296.8 vs. 374.8 min, p = 0.036). Blood loss was significantly less in MI-CP vs. O-CP (807.1 vs. 214.0 mls, p = 0.001), with no difference in post-operative new-onset diabetes (9% vs. 5%). The overall post-operative pancreatic fistula rate was 25.8%, and no significant difference between O-CP and MI-CP or complication rates (45% vs. 40%) was observed. Conclusion Despite increased operative time, MI-CP is feasible and comparable to conventional O-CP with regard to surgical outcomes in well-selected patients.
