A comparison of outcomes of emergent, urgent, and elective surgical treatment of diverticulitis.

Overview

BACKGROUND: There is a controversy regarding the best urgent surgical treatment of colonic diverticulitis. We sought to compare outcomes of patients who underwent surgery for diverticulitis by the type of admission. METHODS: The National Surgical Quality Improvement Program databases were used to examine the clinical data of patients who underwent colorectal resection for diverticulitis during 2012 to 2013. Multivariate regression analysis was performed to identify outcomes of patients. RESULTS: We sampled a total of 13,510 patients admitted for diverticulitis who underwent colorectal resection, of which 7.8% had emergent and 19.7% had urgent operation. Patients with perforation (adjusted odds ratio [AOR] 188.56, P < .01) and preoperative sepsis (AOR 28.17, P < .01) had significantly higher rates of emergent surgery. Patients who underwent emergent operation had higher mortality (AOR 4.08, P = .04) and morbidity (AOR 2.14, P < .01). Emergent operations had a significantly higher risk of anastomosis leakage compared with elective operation (AOR 3.92, P = .02). CONCLUSIONS: Emergent treatment of diverticulitis is associated with a high morbidity and mortality. In the setting of emergent treatment of diverticulitis, colonic anastomosis without a stoma has a high risk of anastomosis leakage.
