Diverticular disease refers to the presence of colon diverticula. Its prevalence increases with age and in a few cases present as diverticulitis. Acute complicated diverticulitis is potentially mortal, since it can perforate and require emergency surgery. The treatment of choice is the excision of the perforated segment and the creation of a proximal colostomy. There are other therapeutic alternatives such as excision with primary anastomosis and novel approaches such as laparoscopic peritoneal lavage. We herein review the new treatments of acute diverticulitis.
