Patient demographics, disease characteristics, and treatment strategies were described. Short\u2010 (emergency surgery, operative morbidity, treatment failure) and long\u2010term (recurrence, elective operation) outcomes were reported.

Mean age was 51.2\u2009\u00b1\u200917.7 years. Eight patients (12.5%) self\u2010identified as being Asian. The majority of patients had uncomplicated disease (90.6%); six (9.4%) presented with complicated diverticulitis. Most cases were diagnosed by computed tomography (78.1%), while 17.2% were diagnosed intra\u2010operatively and 4.7% by pathology. Almost all patients diagnosed by computed tomography were managed nonoperatively. Fifteen patients (23.4%) were managed surgically: ten for suspected appendicitis, three for suspected colon mass, and two for diffuse peritonitis. After a median follow\u2010up of 74.8\u00a0months (IQR 30.2\u2013130.5), only two patients (3.1%) developed recurrent right\u2010sided diverticulitis.
