Purpose This retrospective multicenter cohort study aimed to evaluate the clinical outcomes (mortality rate, operative time, complications) of elective laparoscopic cholecystectomy (LC) when performed by a surgical resident in comparison to experienced consultant in the backdrop of Italian academic centers. Methods Retrospective review of all patients undergoing elective LC between January 2016 and January 2022 at six teaching hospitals across Italy was performed. Cases were identified using the Current Procedural Terminology (CPT) code 5123 (LC without cholangiogram). All cases of emergency surgery, ASA score > 3, or when cholecystectomy was performed with another surgical procedure, were excluded. All suitable cases were divided into 2 groups based on primary surgeon: consultant or senior resident. Main outcome was complication rates (intraoperative and peri/postoperative); secondary outcomes included operative time, the length of stay, and the rate of conversion to open. Results A total of 2331 cases (1425 females) were included, of which, consultants performed 1683 LCs (72%), while the residents performed 648 (28%) surgeries. The groups were statistically comparable regarding demographics, history of previous abdominal surgery, operative time, or intraoperative complications. The rate of conversion to open cholecystectomy was 1.42% for consultant and none for resident ( p  = 0.02). A statistically significant difference was observed between groups regarding the average length of stay (2.2 ± 3 vs 1.6 ± 1.3 days p  = 0.03). Similarly, postoperative complications (1.7% vs 0.5%) resulted in statistically significant ( p  = 0.02) favoring resident group. Conclusions Our study demonstrates that in selected patients, senior residents can safely perform LC when supervised by senior staff surgeons.
