Objectives: Colonoscopy is a popular tool for screening for colon cancer throughout the world. Theincidence of polypectomy and follow-up colonoscopy are persistently increasing but the studies aboutfollow-up test after polypectomy are still lack of its domestic sources. This study is designed to look intothe recurrence rate of colon polyps and risk factors after polypectomy. Methods: This is a retrospective study by reviewing medical charts of 147 patients who underwentpolypectomy and follow-up colonoscopy from Jan. 2000 to Mar. 2008. The Kudo classification was used todescribe the polyps found in the colonoscopy. The follow-up period was defined as the term betweenpolypectomy and the first colonoscopy follow up. Results: Seventy six point two percent of the enrolled patient were male and the mean age was 56.5 ±8.1. Mean follow-up period was 24.9 ± 13.7 (6 - 65) months. The cumulative recurrence rate of 1 year was11.6%. The rate of 2 years was 36.7% and that of 3 years was 55.8%. The number of polyps was the factorwhich statistically showed significant relation of its recurrence rate. The histological morphology characteristicof polyps could be one independent factor which may be associated to the recurrence of polyps. Conclusions: The importance of colonoscopy follow up after polypectomy was clearly emphasized throughthe cumulative recurrence rate of 55.8%. Therefore, there is a need for more domestic studies with a largenumber of patients about the recurrence of polyps after polypectomy.
