Abstract:
1. 5 cm) sessile colorectal polyps referred for EMR. After submucosal injection of epinephrine, either en bloc or piecemeal snare polypectomy were performed. All resected specimens were retrieved for pathologic study. Follow-up colonoscopy was performed in all patients after EMR. Results All 157 polyps were removed completely. All lesions are larger than 1. 5cm, but 3 less than 1 cm on the submucosa of rectum. The largest one is 13 cm X 12 cm. No complication occurred. Histopathologic assessment of the resection specimens revealed the following: adenoma, 123; dysplasia, 80; mucosal carcinoma, 11; hyperplastic polyps, 20; rectal carcinoid, 3. Two patients who had rectal adenoma that was larger than 7cm recurrence happened at the resection site after 1 and 3 months follow-up respectively, than removed completely by hot biopsy forceps showed hyperplastic and villous adenoma on pathological study. No more residual tumor was detected for 6-12 months. Conclusion EMR with an intensive follow-up program is a safe and effective treatment for large sessile colorectal polyps and mucosal carcinoma.
