Article Title: Do prolonged operative times obviate the benefits associated with minimally invasive colectomy?
Abstract: BACKGROUND: Minimally invasive colectomy is associated with improved length of stay and decreased postoperative morbidity. Little is known regarding the impact of prolonged operative time on the benefits afforded by minimally invasive colectomy. METHODS: The American College of Surgeons National Surgical Quality Improvement Program procedure targeted colectomy dataset was queried to identify elective right and left colectomies performed between 2011 and 2017. Multivariable modeling was used to compare rates of composite 30-day death or serious morbidity, overall morbidity, mortality, anastomotic leak, surgical site infection, and length of stay for prolonged minimally invasive cases to those for average duration open cases. RESULTS: A total of 16,602 right colectomies and 36,557 left colectomies were identified. Median operative times for open and minimally invasive right colectomies were 107 min and 129 min (P .01), while that for open left colectomies was 128 min and 156 min for minimally invasive left colectomies (P .01). Cohorts were stratified by quartiles of operative time with the highest (fourth) quartile defined as a prolonged operating time. When compared with an average duration open colectomy, prolonged minimally invasive right colectomies and left colectomies were associated with decreased risk-adjusted rates of overall morbidity, surgical site infection, and with lesser lengths of stay (P  .05). Prolonged minimally invasive left colectomies were also associated with improved rates of composite 30-day death or serious morbidity relative to average open left colectomies (odds ratio 0.66, 95% confidence interval, 0.54-0.79). CONCLUSION: Prolonged operating times of an minimally invasive approach do not obviate the benefits of an minimally invasive approach to colectomy.
