PurposeThe aim of this study was to evaluate the laparoscopic approach and pre- and postoperative conditions as predictors of 30-day mortality and morbidity in elective colectomy.MethodsElective colectomies were identified in the 2005-2008 American College of Surgeons National Surgical Quality Improvement Program database. Multivariate logistic regression was used to model 30-day mortality and morbidity following elective colectomy. Propensity scores were calculated to decrease selection bias.ResultsDuring the period studied, 14,321 patients underwent open colectomy and 10,409 underwent laparoscopic colectomy. Factors that significantly influenced mortality included male gender [odds ratio (OR) 1.4, confidence interval (CI) 1.07-1.9]; age (OR 1.07, CI 1.05-1.08); comorbidities including dyspnea, ascites, congestive heart failure, dialysis, or disseminated cancer; and postoperative conditions including reintubation (OR 2.6, CI 1.6-4.0), renal failure (OR 3.8, CI 2.1-6.9), stroke (OR 6.44, CI 2.4-17.6), and septic shock (OR 13.1, CI 8.76-19.4). While laparoscopy was not independently associated with mortality, it was associated with decreased postoperative morbidity including reintubation (OR 0.74, CI 0.59-0.91), renal failure (OR 0.60, CI 0.4-0.91), septic shock (OR 0.74, CI 0.59-0.92), wound infection (OR 0.58, CI0.44-0.77), and pneumonia (OR 0.71, CI 0.59-0.86).ConclusionsBased on this analysis, laparoscopy was associated with a decrease in 30-day postoperative morbidity for colectomy. However, after adjusting for preoperative comorbidities and postoperative morbidities, laparoscopy did not independently influence mortality after colectomy.
