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.
