Background:
Colonic diverticulitis shows a high recurrence rate.
Aims:
To assess the efficacy of three different therapeutic strategies in preventing diverticulitis recurrence.
Materials And Methods:
One hundred thirty patients suffering from Acute Uncomplicated Diverticulitis (AUD) (81 males, 49 females, mean age 64.71 years, range 40-85) were prospectively assessed. After obtaining remission, considered present when both endoscopic and histological damage were absent, the patients were treated with mesalazine 1.6 g/day (59 patients, group A), or rifaximin 800 mg/day for 7 days every month (52 patients, group B). Clinical, endoscopic and histological follow-up was performed after 6, 12 and thereafter every 12 months after diagnosis of AUD.
Results:
Seven patients were excluded from final evaluation because they were lost to follow-up. Fifty-five group A patients and 49 group B patients patients were available for the final assessment at the end of a 24-month follow-up. Sustained remission was significantly higher in group A with respect to group B.
Conclusions:
Patients taking mesalazine have lower risk of diverticulitis recurrence than patients taking rifaximin because of the lower prevalence of persisting endoscopic and histological inflammation.

A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the colonic...
