Colon adenoma recurrence after endoscopic high-frequency electric polypectomy / 中华消化内镜杂志

ABSTRACT

Objective To study the recurrence of colon adenoma after endoscopic high-frequency electric polypectomy.Methods The data of 238 patients undergoing endoscopic polypectomy between 2000 and 2008 were retrospectively analyzed.The cumulative recurrence rates at 0-2 years,＞2-5 years and ＞5-8 years after polypectomy,median recurrence time and main risk factors for recurrence were identified based on the features of adenomas detected on initial colonoscopy.Results The cumulative recurrence rates of adenoma at the surveillance examination were 61％,81％,and 84％ for the three intervals,respectively.On multivariate analysis,gender,age,extra-colonic tumor history,alcohol drinking history and adenoma number at initial examination were the independent risk factors of adenoma recurrence.Conclusion We suggest a 2-year surveillance interval for Chinese patients with colonic adenoma after the initial endoscopic polypectomy,a 20-month surveillance interval for males over 60 years old who have more than 2 sdenomas at the initial colonoscopy,and an even shorter interval for those with exira-colonic tumor history or alcohol drinking history.
