[Show abstract][Hide abstract] ABSTRACT: A modified per os double contrast examination of the colon was used in 62 elderly patients in whom conventional barium enema had been unsuccessful. We created endogenous gas generation instead of air insufflation by per os administration of a special mixture containing barium sulfate, lactulose and gastrografin. Good quality double contrast images of the colon were obtained after 12 hours in 59 of the 62 patients. The sensitivity of the method was 100% in 6 patients suffering from carcinoma and in 15 patients suffering from diverticular disease. However, the method failed to demonstrate small solitary polyps in 5 patients and it was also negative in another 27 patients. 7 of these had negative endoscopy and in the remaining a definite diagnosis was not established by any other method. It seems that this method may become an alternative for investigation of suspected colonic pathology in the elderly patients with difficulty in retaining the barium enema.
