Diverticular colitis: diagnosis and management.
Diverticular colitis is a recently recognized nosological entity in which a chronic focal mucosal sigmoid colitis occurs in association with diverticulosis. It usually presents with rectal bleeding and may be difficult to distinguish clinically, endoscopically and pathologically from other segmental colitides including ulcerative, Crohn's, ischaemic, infective and NSAID-induced colitis as well as diverticulitis. Uncontrolled data suggests that most patients respond satisfactorily to treatment with a high fibre diet, antibiotics and/or aminosalicylates, but a minority with persistent or recurrent symptoms require sigmoid resection. This paper reviews the literature on diverticular colitis and concludes with an algorithm suggesting the optimal management of patients who present with rectal bleeding in association with segmental sigmoid colitis and diverticulosis.
