Colonic Diverticulitis
Introduction
Diverticulitis is inflammation with or without infection of a diverticulum, which can result in phlegmon of the bowel wall, Peritonitis , A colonic diverticulum is a saclike pouch of colonic mucosa and submucosa that protrudes through the muscular layer of the colon; because it does not contain all layers of the bowel, it is considered a pseudodiverticulum (see also Definition of Diverticular Disease ). Many people have multiple colonic diverticula ( Colonic Diverticulosis ). The incidence of diverticulosis rises with increasing age; it is present in 75% of people > 80 years. In people > 50 years, acute diverticulitis is most common among women; in those < 50 years, it is most common among men. Patients with HIV and those undergoing chemotherapy are at increased risk of developing acute diverticulitis ( Diverticula, Diverticulosis, and Diverticulitis (https://www.youtube.com/watch?v=TL9_WKuNfu0) by Osmosis (https://open.osmosis.org/) is licensed under CC-BY-SA 4.0 (https://creativecommons.org/licenses/by-sa/4.0/). Diverticula are usually asymptomatic but sometimes become inflamed (diverticulitis). One study reported that 4.3% of patients with documented diverticulosis developed diverticulitis over an 11-year follow-up period ( General references ). Diverticulitis that is managed nonoperatively can recur as either an acute or chronic process. The risk of a recurrent acute episode is up to 39%, although reported rates vary widely ( General references ). A large population-based study found that after an episode of acute diverticulitis the recurrence rate at 1 year was 8% and at 10 years was 22% (
