BackgroundDiverticulosis of the right colon occurs in a small percentage of patients in Western countries. Clinical presentation of right-sided colon diverticulitis is indistinguishable from that of acute appendicitis, and the majority of patients undergo surgical intervention for presumed appendicitis. The liberal use of diagnostic radiological modalities whenever appendicitis was suspected led to correct diagnosis and also to more preoperative diagnosis of right-sided diverticulitis, which consented conservative medical therapy in cases of uncomplicated right-sided diverticulitis. The aim of the study was to report the outcome in patients with right-sided diverticulitis diagnosed nonoperatively using computed tomography scanning and treated conservatively.MethodsPatients with clinical and radiological diagnosis of cecal or right colon diverticulitis treated conservatively between January 2005 and December 2007 were included. The demographic and clinical data were retrospectively analyzed.ResultsFifteen patients were included in this study. The median age was 52 years (range, 34-72 years) and the duration of symptoms was 4 days (range, 1-9 days) before the diagnosis. The median hospital stay was 5 days (range, 1-9 days). All patients were successfully treated with medical therapy. During a median follow-up of 32 months (range, 24-52 months) only one patient (6.6%) had a recurrent attack, and he was successfully treated again with medical therapy.ConclusionThe routine use of the computed tomography scan for abdominal pain in the right lower quadrant, and whenever right-sided diverticulitis is suspected, improves diagnosis and reduces surgical interventions. The current study provides additional data in support of conservative therapy as the initial treatment in acute right-sided diverticulitis, even in cases of recurrence.
