SUMMARY OBJECTIVE: The aim of this study was to evaluate whether laparoscopic adrenalectomy can be safely performed by senior residents (4 years and above) with the guidance of senior surgeons. METHODS: Patients who underwent unilateral laparoscopic transabdominal adrenalectomy between January 2012 and December 2023 were enrolled. Patients were divided into two groups. Patients’ demographic, clinical, and surgical data were recorded and analyzed. RESULTS: A total of 106 patients were enrolled in the study. Twenty of the patients were male, and 86 were female. The mean age was 51.8 (±standard deviation±12.1). In group 1, there were 83 patients (78.3%) who were operated on by a senior surgeon, and in group 2, there were 23 patients (21.7%) who were operated on by a senior resident. There was no significant difference between the two groups in terms of age, gender, and American Anesthesia Society score. A statistically significant difference was detected between the two groups in terms of mass diameter (p=0.042). In multivariate analysis, being operated on by a senior surgeon was not a risk factor for either postoperative complications or conversion to open surgery. CONCLUSION: In conclusion, laparoscopic adrenalectomy can be safely performed by senior residents under the supervision of senior surgeons.

Background/Objectives: The evolution of minimally invasive techniques has established advanced laparoscopic skills as an increasingly essential component of surgical curricula. However, the feasibility of senior residents performing technically demanding procedures such as Laparoscopic Colorectal Surgery (LCS) remains debated. This study evaluated the perioperative safety, short-term oncologic outcomes, and operative-time implications of supervised Laparoscopic Colorectal Surgery (LCS) performed by senior residents (post-graduate years 3 to 5 of a 5-year program). Methods: A retrospective observational cohort study of 136 patients undergoing curative-intent LCS for primary colorectal malignancy was conducted. Patients were stratified into a Specialist group (n = 102) and a Resident group (n = 34). Residents were senior trainees operating under the direct intraoperative supervision of experienced specialists. Perioperative metrics, patient safety endpoints, and short-term oncologic outcomes were compared. Results: The groups were demographically and pathologically well-matched, demonstrating similar distributions of advanced-stage (T3–T4) tumors and high Body Mass Index. Median operative time was significantly prolonged in the Resident group (340 vs. 290 min; p = 0.023). However, no significant differences were observed regarding the median length of hospital stay (9 vs. 8 days; p = 0.057), the incidence of anastomotic leakage (3.4% vs. 3.8%; p = 1.000), or positive surgical margin rates (5.9% vs. 10.8%; p = 0.517). No statistically significant difference in median lymph node yield was detected between the Resident and Specialist cohorts (17 vs. 16 nodes; p = 0.251). Conclusions: Under direct specialist supervision, resident-performed LCS was associated with no material difference in the measured short-term outcomes within this single-center supervised training model and the eligibility criteria used. The prolongation of operative time associated with resident participation appears to be a safe and acceptable aspect of surgical training.
