Abstract
BACKGROUND: Multiple studies examining the impact of resident involvement on patient outcomes in general surgical operations have shown an associated increase in morbidity and operative time. However, these studies included basic and advanced laparoscopic and open operations. The aim of this study was to examine the impact of resident involvement on outcomes specifically in patients who underwent complex minimally invasive gastrointestinal operations. STUDY DESIGN: The American College of Surgeons NSQIP database was reviewed for patients who underwent laparoscopic colectomy and laparoscopic paraesophageal hernia and anti-reflux procedures between 2002 and 2010. Data were analyzed based on operations performed with a resident involved compared with those performed by an attending surgeon without resident involvement. Primary end points included risk-adjusted 30-day mortality, 30-day reoperation, and 30-day serious morbidity. Secondary end points were operative time, hospital length of stay, and 30-day overall morbidity. RESULTS: A total of 31,736 cases were analyzed; 63.3% of cases had a resident involved in the operation and 36.7% were performed by an attending without resident involvement. Operative time was significantly longer in cases performed with a resident (162 vs 138 minutes in attending-only cases; p < 0.01), however, there were no significant differences between groups with regard to hospital length of stay (4.5 vs 4.5 days, respectively). Compared with cases without resident involvement, risk-adjusted outcomes for cases with resident involvement showed no significant differences in 30-day serious morbidity (odds ratio = 1.03; 95% CI, 0.94-1.14; p = 1.0), 30-day mortality (odds ratio = 0.83; 95% CI, 0.60-1.15; p = 1.0), or 30-day reoperation (odds ratio = 0.93; 95% CI, 0.81-1.06; p = 1.0). CONCLUSIONS: Resident involvement in complex laparoscopic gastrointestinal procedures is associated with an increase in operative time with no impact on postoperative outcomes.
