Impact of Resident Post-Graduate Year on Laparoscopic Cholecystectomy Outcomes

Abstract

Introduction Laparoscopic cholecystectomy is a minimal access procedure in which the gallbladder is removed by laparoscopic techniques. Effective training for laparoscopic surgery should focus on not only understanding the anatomy and procedural steps but also acquiring the specific gestures and techniques of this type of surgery that may differ from those used in traditional open surgery. The aim of our study was to analyze whether the laparoscopic cholecystectomy performed by surgeons in training is a safe procedure. Material and methods This is a retrospective review of 433 patients who were divided into two groups: laparoscopic cholecystectomies performed by trainees and those performed by senior surgeons. Results Around 66% of surgeries were performed by resident surgeons. There was no demographic difference between residents and senior surgeons. Operative time was significantly longer in the residents' group compared to senior surgeons' group (96 minutes vs 61 minutes; p<0.001). The overall intra- and post-operative complication rates were 3.1% and 2.5%, respectively, with no significant difference between the two groups (p=0.368 and p=0.223). Conversion to open laparotomy was required in 8% of cases in each group (p=0.538). The mean length of hospital stay after surgery was significantly longer in patients operated by residents (p<0.001). We did not notice any case of mortality in both groups.
