The radiological diagnosis of polyps in the presence of diverticular disease

Abstract

Double contrast Ba enemas in 20 patients with endoscopically proven polyps within a segment of diverticular disease were reviewed. Of the polyps 90% were detected. The increased density sign and negative shadow filling defect proved valuable in their detection. Antispasmodics are advised to distend the sigmoid and allow double contrast views to be obtained. With severe diverticular changes it may be impossible to exclude a polyp and if the patient complains of rectal bleeding, endoscopy is indicated.
