Background The changing paradigm of surgical residency training has raised concerns about the effects on the quality of training. The purpose of this study is to identify if resident participation in laparoscopic adrenalectomy (LA) and open adrenalectomy (OA) cases is associated with deleterious outcomes. Materials and methods This is a retrospective study using the American College of Surgeons National Surgical Quality Improvement Program database. Data from patients undergoing LA and OA from 2005 to 2010 were queried. Preoperative variables as well as intra- and post-operative outcomes for each procedure were evaluated. Multivariate logistic regression was used to analyze if resident participation was associated with significant differences in outcomes, compared with no resident participation. Subset analysis was done to determine possible differences in outcomes based on the level of resident participating, divided into junior (Post Graduate Year [PGY]1-3), senior (PGY4-5), or fellow (≥PGY6) levels. Results A total of 3219 adrenalectomies were performed. Of these, 735 (22.8%) were OAs and 2484 (77.2%) were LAs. Residents were involved in 2582 (80.2%) surgeries, which comprised 1985 (76.9%) LAs and 597 (23.1%) OAs. Senior residents or fellows performed majority of the cases (85.2%). Mean operative time was significantly higher with resident participation in LA (P < 0.0001) and OA group (P < 0.0001). On multivariate analysis, resident participation was not associated with significant differences in the operative outcomes of 30-d mortality or postoperative complications after laparoscopic or OA. Conclusions Although resident participation does increase operative time in LA and OA, this does not appear to be clinically significant and does not result in adverse patient outcomes.
