Abstract
AbstractAimA laparoscopic approach to total colectomy (TC) for inflammatory bowel disease (IBD) is being increasingly used, but data on its comparative benefits over open TC are conflicting. The aim of this study was to examine 90‐day outcomes following laparoscopic and open TC for IBD in a nationwide cohort after the introduction of laparoscopy.MethodIBD patients undergoing TC in Denmark from 2005 to 2017 were identified from the Danish National Patient Registry. We used Kaplan–Meier methodology to estimate mortality and Cox regression analysis to estimate adjusted mortality rate ratios (aMRRs) and adjusted hazard ratios (aHRs) of reoperation, readmission and intensive care unit (ICU) transfer, comparing patients undergoing laparoscopic versus open TC.ResultsWe identified 1095 patients undergoing laparoscopic TC and 1523 patients undergoing open TC. Following emergency TC, 90‐day mortality was 2.8% (1.6%–4.9%) after laparoscopic TC and 9.1% (7.0%–11.8%) after open TC. Ninety‐day mortality was 0.9% (0.3%–2.5%) after laparoscopic TC and 2.6% (1.5%–4.3%) after open elective TC. The aMRRs associated with laparoscopic TC were 0.45 (95% CI 0.25–0.80) in emergency cases and 0.29 (95% CI 0.10–0.86) in elective cases. Risks of readmission were comparable following laparoscopic versus open TC, both in emergency [aHR = 0.93 (95% CI 0.76–1.15)] and elective [aHR = 0.83 (95% CI 0.68–1.02)] cases, while risks of ICU transfer and reoperation were lower following laparoscopic TC, both in emergency cases [aHR = 0.53 (95% CI 0.35–0.82) and aHR = 0.26 (95% CI 0.15–0.47)] and elective [aHR = 0.58 (95% CI 0.35–0.95) and aHR = 0.37 (95% CI 0.21–0.66)] cases.ConclusionThe introduction of laparoscopic TC for IBD in Denmark was not associated with increased mortality or morbidity. In fact, laparoscopic TC for IBD may be associated with lower short‐term mortality and morbidity compared with open TC.
