Non-operative treatment of right-sided colonic diverticulitis has good long-term outcome: a review of 226 patients

Original Article



Data highlighting the long-term outcome following an initial episode of right-sided colonic diverticulitis is lacking. This study aims to evaluate and follow up on all patients with right-sided colonic diverticulitis.


A retrospective review of all patients who were discharged with a diagnosis of right-sided colonic diverticulitis from January 2003 to April 2008 was performed.


A total of 226 patients, with a median age of 49 (range, 16–93) years, were admitted for acute right-sided colonic diverticulitis. The majority of the patients (n = 198, 87.6 %) had mild diverticulitis (Hinchey Ia and Ib). Seventy-three (32.3 %) patients underwent emergency surgery. The indications of surgery were predominantly suspected appendicitis (n = 50, 22.1 %) and perforated diverticulitis (n = 16, 7.1 %). Right hemicolectomy was performed in 32 (43.8 %) patients, while appendectomy, with or without diverticulectomy, was performed in the rest (n = 41, 56.2 %). There were seven patients who underwent elective right hemicolectomy after their acute admissions.Over a median duration of 64 (12–95) months, there were only nine patients who were readmitted 12 times for recurrent diverticulitis at a median duration of 17 (1–48) months from the index admission. The freedom from failure (recurrent attacks or definitive surgery (right hemicolectomy)) at 60 months was 92.0 % (95 % Confidence interval 86.1 %–97.9 %).


Right-sided diverticulitis is commonly encountered in the Asian population and often gets misdiagnosed as acute appendicitis. If successfully managed conservatively, the long-term outcome is excellent.
