Patients with acute diverticulitis can present with uncomplicated or complicated disease (figure 1). (See "Clinical manifestations and diagnosis of acute diverticulitis in adults".)

Acute uncomplicated diverticulitis is a self-limited and confined inflammatory process that may include a microperforation but excludes an abscess, macroperforation, and/or peritonitis. Complicated diverticulitis refers to a clinical presentation with inflammatory manifestations that include peritonitis, obstruction, perforation, and/or abscess formation. This topic review will focus on the nonoperative management of patients with acute uncomplicated diverticulitis. Epidemiology, pathophysiology, clinical manifestations, and management of complicated diverticulitis are reviewed elsewhere:

(See "Colonic diverticulosis and diverticular disease: Epidemiology, risk factors, and pathogenesis".)

(See "Clinical manifestations and diagnosis of acute diverticulitis in adults".)

(See "Segmental colitis associated with diverticulosis".)
