Abstract

BACKGROUND/AIMS: The detection and removal of colorectal polyps are important for secondary prevention of colorectal cancer. We investigated the characteristics and histopathologic finding of polyps to better plan their management.
METHODS
We analyzed 334 patients who underwent polypectomies for 770 colorectal polyps between October, 2005 and April, 2007 at Bong Seng Memorial Hospital.
RESULTS
Colorectal polyps were frequent in the sixth decade in both sexes. The ratio of male to female patients was 1.72:1. Abdominal pain/discomfort was the most common symptom (34.4%), and the most common site of polyp localization was the rectosigmoid colon. Histopathologic examination showed tubular adenomas (54.6%), hyperplastic polyps (36.4%), and inflammatory polyps (5.6%). Adenomatous polyps were more common in patients with multiple polyps than in patients with a single polyp. Adenomatous polyps with villous histology were more common in patients with large polyps than in patients with small polyps. Non-neoplastic polyps were common before the fifth decade. Neoplastic polyps were common past the fifth decade.
CONCLUSIONS
In this study, tubular adenomas were frequently found on histopathologic examination, sessile type were frequently found on gross examination, and colorectal polyps were found principally in the rectosigmoid colon. Neoplastic polyps were more frequent in patients beyond the fifth decade. There fore colonoscopy examination is recommended for secondary prevention of colon cancer.
