Randomized Controlled Trial
Randomized clinical trial of elective resection versus observation in diverticulitis with extraluminal air or abscess initially managed conservatively.
The aim of this RCT was to determine whether elective resection following successful non-operative management of a first episode of acute sigmoid diverticulitis complicated by extraluminal air with or without abscess is superior to observation in terms of recurrence rates. ⋯ The majority of patients observed following conservative management of diverticulitis with local extraluminal air do not require elective surgery. Registration number: NCT01986686 (http://www.clinicaltrials.gov).
