ABSTRACT
INTRODUCTION: Colectomy is relatively common in inflammatory bowel diseases (IBD), occurring more in Ulcerative Colitis (UC) as compared to Crohn's disease (CD). The surgical outcomes among this mixed population of patients are not well understood. This study aims to determine the predictors of post colectomy surgical outcomes in this patient population. METHODS: Using the National Surgical Quality Improvement Project (NSQIP) demographics, preoperative and post-operative data were analyzed for all patients undergoing colectomy for either CD or UC. Multiple variables were linked to several outcomes including mortality, anastomotic leak, and reoperation post colectomy. RESULTS: A total of 5049 IBD patients that underwent colectomy were identified. Rate of reoperation and anastomotic leak were significantly increased with steroid intake with an Odds Ratio (OR) of 1.66 (95% Confidence Interval (CI) (1.26-2.19)) and 1.81 (95%CI (1.34-2.45)) respectively. As for 30-day mortality, it was significantly lower among patients on steroid (OR=0.41; 95%CI (0.19-0.86)). Comparing UC to CD, anastomotic leaks were less common among UC patients (OR=0.53; 95%CI (0.37-0.76)), but 30-day mortality was significantly more prevalent among UC patients (OR=8.11; 95%CI (4.22-15.6)). CONCLUSION: Among IBD patients undergoing colectomy, major surgical complications except 30-day mortality appear to increase with the use of preoperative steroids.
