Management of right-sided diverticulitis: A retrospective review from a hospital in Japan

Abstract

Patients with acute right-sided diverticulitis seldom require emergency surgery unless acute appendicitis is misdiagnosed preoperatively. Most cases of uncomplicated right-sided diverticulitis, even if it is recurrent, can be treated conservatively.

Characteristics of Colonic Diverticulitis and Factors Associated With Complications

“…Consequently, leftsided diverticulosis is more common in older patients. 25 in asians, diverticulitis occurs more frequently in the right colon, 26 a finding consistent with our results. in Western patients, however, diverticular disease usually affects the sigmoid and descending colon, with less frequent involvement of the cecum and ascending colon.…”

Risk factors for recurrence of right colonic uncomplicated diverticulitis after first attack

“…The recurrence rate after conservative management for right colonic uncomplicated diverticulitis varies among studies (approximately 7.1-20.5 %) [7,9,10]. The causes of recurrence are not yet understood.…”

Colonoscopy After Computed Tomography–diagnosed Acute Right-sided Diverticulitis May Be Unnecessary

“…1,2 In Japan, as in other Asian countries, more than half of the diverticulitis cases are right-sided. 3 No study has reported on the need for screening colonoscopy after diagnosing diverticulitis in Asian patients.…”
