Nonoperative management of right colonic diverticulitis using radiologic evaluation.
OBJECTIVE
Although a few reviews have been conducted, nonoperative management may be the mainstay of therapy for uncomplicated right colonic diverticulitis. With increasing use of radiological evaluation for diverticulitis, the status of the disease is becoming more accessible. In this study, clinical outcomes of nonoperative management for right colonic diverticulitis were assessed according to disease status using radiological evaluation.


METHODS
From April 2000 to March 2007, 296 patients were admitted for acute right colonic diverticulitis upon first attack and were treated with nonoperative management. The status of diverticulitis was classified using ultrasonography and/or computed tomography as inflamed diverticulum or phlegmon in 276 patients or pericolic abscess in 20 patients. Uncomplicated diverticulitis was defined as inflamed diverticulum or phlegmon. Length of hospital stay, antibiotic use, failure of initial therapy and the incidence of recurrence after nonoperative management were assessed.


RESULTS
The mean length of hospital stay and antibiotic use were 6 and 4.7 days respectively. All patients were successfully treated with the initial medical therapy and their hospital stays were uneventful. Of the 276 patients with an uncomplicated diverticulitis, two patients (1%) had a recurrence during follow-up that could be managed nonoperatively. Of the 20 patients with pericolic abscesses, four patients (20%) had a recurrence. One patient underwent laparoscopic ileocolic resection and the other patients were treated nonoperatively.


CONCLUSIONS
Nonoperative management may be the treatment of choice for right colonic diverticulitis with inflamed diverticulum or phlegmon. Diverticulitis with pericolic abscess should be treated with additional care.
