Colectomy for caecal and sigmoid volvulus: a national analysis of outcomes and risk factors for postoperative complications.

Abstract

Colonic volvulus is a common entity encountered by colorectal surgeons, but there are few reports of national data regarding postoperative outcomes. The aim of this study was to describe the volvulus population, 30-day outcomes following right- and left-sided colectomy and risk factors for postoperative complications. The American College of Surgeons National Surgical Quality Improvement Program Database from 2012 to 2015 was utilized to identify patients with the diagnosis of 'volvulus' who underwent right- or left-sided colectomy. Primary outcomes were overall morbidity and mortality. A total of 2175 patients were identified (661 right colectomy and 1514 left colectomy). Risk factors for complications following right-sided colectomy included: age, male gender, smoker, systemic inflammatory response syndrome, sepsis, septic shock and American Society of Anesthesiologsts class ≥ 4. Risk factors for complications following left-sided colectomy included: age, male gender, systemic inflammatory response syndrome, sepsis and septic shock. Several nonmodifiable risk factors were identified for complications following colectomy for volvulus. These risk factors can be used in patient/family counselling and discharge planning.
