Cecal volvulus in rural Kenya: delayed presentation contributes to high mortality

Abstract

Abstract Background Cecal volvulus, which is a torsion involving the cecum, terminal ileum, and ascending colon around its own mesentery, results in a closed-loop obstruction. It is a rare reported cause of adult intestinal obstruction. This study aimed to review the clinical presentation, management, and outcomes at a rural, resource-limited referral center. Methods We performed a retrospective review of all patients with a diagnosis of cecal volvulus between January 1st, 2009 and December 31st, 2019 at Tenwek Hospital in Bomet, Kenya. The outcome of survival was compared by the time to presentation. Mortality was also compared with prior reports of intestinal obstruction at our institution. Results Thirteen patients were identified with a mean age of 52 years and a mean symptom duration of 5 days. All patients presented with abdominal pain and distension. Seven patients (54%) presented with perforation, gangrene, or gross peritoneal contamination. Identified risk factors were Ladds bands with malrotation, adhesions, and a sigmoid tumor. Procedures included primary resection and anastomosis (7), damage control (3) with anastomosis on second-look in 2 of these, simple surgical detorsion (1), and surgical detorsion and cecopexy (2). There were four mortalities (31%), of which all had delayed presentation with perforation and fecal contamination. Delays to presentation were associated with mortality (p = 0.03). Cecal volvulus resulted in increased perioperative mortality compared to all intestinal obstructions presenting to the institution (p < 0.0001). Conclusions Cecal volvulus carries a high risk of mortality. A high index of suspicion and early consideration in the differential diagnosis of intestinal obstruction should be considered to reduce the mortality associated with the delay in preoperative diagnosis.
