Elective Surgical Treatment of Diverticulitis

Elective surgical resection in cases of diverticulitis should be offered to patients who have experienced two episodes. High-risk patients such as immunocompromised individuals or transplant patients may warrant resection after one episode. It is controversial whether young patients or patients with right-sided diverticulitis need to be treated differently. Chronic diverticulitis can be successfully treated surgically in selected cases. Adequate surgical resection margins should include the top of the true rectum and the proximal extent of thickened inflamed colon to minimize the risk of recurrence. Careful operative planning and the use of proximal diversion if unsuspected significant inflammatory changes are encountered will improve surgical outcomes.
