Analysis of colonic adenomas recurrence after adenoma removes

Objective: Some neoplasms are missed in colonoscopy procedures make the colonic adenoma surveillance intervals difficult to put into practice. Our research tried to avoid the influence of missed neoplasms, analyzed the adenoma recurrence and provided surveillance suggestion for patients after polypectomy or other endoscopic therapy. Methods: A total of 303 patients with colonic adenoma and lesions remove between 2005 and 2009 were respectively analyzed, all patients were suggested colonoscopy within 6 months after initial colonoscopy and removed missed adenomas. Every patient underwent surveillance colonoscopies every 1-2 years to detect the adenomas recurrence. Results: The median recurrence time was 23 months, male patients, patients older than 60 years, patients with extracolonic tumor history; with alcohol history and patients with >= 3 adenomas has high risk of adenoma recurrence. Conclusions: The first surveillance colonscopy are suggested 24 months after initial colonscopy, if patients are male patients, older than 60 years, with extracolonic tumor history or drinking history in the mean time, shorter surveillance interval are suggested.
