Minimally Invasive Surgery is Associated with Improved Outcomes Following Urgent Inpatient Colectomy.

Abstract

Objectives:The use of minimally invasive techniques for urgent colectomies remains understudied. This study compares short-term outcomes following urgent minimally invasive colectomies to those following open colectomies.Methods & Procedures:The American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) colectomy database was queried between January 1, 2013 and December 31, 2018. Patients who underwent elective and emergency colectomies, based on the respective NSQIP variables, were excluded. The remaining patients were divided into two groups, minimally invasive surgery (MIS) and open. MIS colectomies with unplanned conversion to open were included in the MIS group. Baseline characteristics and 30-day outcomes were compared using univariable and multivariable regression analyses.Results:A total of 29,345 patients were included in the study; 12,721 (43.3%) underwent MIS colectomy, while 16,624 (56.7%) underwent open colectomy. Patients undergoing MIS colectomy were younger (60.6 vs 63.8 years) and had a lower prevalence of either American Society of Anesthesiology (ASA) IV (9.9 vs 15.5%) or ASA V (0.08% vs 2%). After multivariable analysis, MIS colectomy was associated with lower odds of mortality (odds ratio = 0.75, 95% confidence interval: 0.61, 0.91 95% confidence interval), and most short-term complications recorded in the ACS NSQIP. While MIS colectomies took longer to perform (161 vs 140 min), the length of stay was shorter (12.2 vs 14.1 days).Conclusions:MIS colectomy affords better short-term complication rates and a reduced length of stay compared to open colectomy for patients requiring urgent surgery. If feasible, minimally invasive colectomy should be offered to patients necessitating urgent colon resection.
