[Diverticula of the right colon. The diagnosis and treatment of complications].
BACKGROUND: Diverticula are localized in the right colon with a rate of 6.7-14% in Western countries. Two types of diverticula have been described in the right colon, on the basis of etiologic and pathological features: multiple diverticula and solitary diverticulum of the caecum. The most common clinical presentation of the right-sided colonic diverticula is an acute inflammatory complication, which is difficult to distinguish from other causes of right iliac fossa pain. METHODS: A survey of the literature is presented and personal experience relative to 4 cases of acute diverticulitis of the right colon observed over a 10-year period is described. RESULTS: In all the patients the preoperative diagnosis was acute appendicitis. In two cases the poor clinical conditions of the patients were associated with the free perforation of a solitary caecal diverticulum and diffuse faecal peritonitis. A temporary caecostomy was therefore required. In two cases a localized inflammatory mass was found around a perforated solitary diverticulum of the caecum. An ileocaecal resection was performed. CONCLUSIONS: The purpose of this study is to emphasize the epidemiological, etiologic and clinical features of right-sided colonic diverticula, and the diagnostic and therapeutic management of their complications.
