Abstract

Background/Aims: Conventional colonoscopy is limited in some patients with several causes, such as fixed angulation, extensive loop or adhesion. Therefore, small-caliber scopes are considered alternatives to unsuccessful conventional colonoscopy. The aim of this study is to evaluate the usefulness of gastroscope in patients with unsuccessful colonoscopy.
Methods: From May 2008 to April 2009, a total of 2,548 colonoscopies were performed in Wonkwang University Hospital. The gastroscope was used subsequently when conventional colonoscopy failed.
Results: There were 27 cases (1.06%) of unsuccessful colonoscopy. The causes of failure were assessed as fixed angulation of the sigmoid colon (59.2%, 16/27), excessive looping (14.8%, 4/27), stricture (14.8%, 4/27), sigmoid diverticulosis (7.4%, 2/27), and adhesion of transverse colon (3.7%, 1/27). The average time of intubation to cecum with the gastroscope was 7 minutes and 28 seconds (range, 2 to 20 minutes). With the gastroscope, 77.8% (21/27) were intubated to the cecum. The pain score of gastroscope was reduced, as compared with that of conventional colonoscopy (4.95 vs. 5.94, P<0.001).
Conclusions: Gastroscope would be a useful alternative tool in patients with unsuccessful colonoscopy.
