Preliminary results of examination of the large bowel with the colonoscope

In 20 patients the colon was inspected with a CF-LB "Olympus" coloscope. The most frequent indication for colonoscopy were doubtful radiological changes in the colon requiring differential diagnosis. Thirteen patients were examined trying to inspect the whole colon and in 9 cases the cecum was reached after 10 to 60 min. In 3 cases colonoscopy demonstrated presence of colonic carcinoma (two tumors located in the cecum), and in 4 other cases this possibility was ruled out and it was possible, thus, to avoid exploratory laparotomy.
