Endoscopic Mucosal Resection for Treatment of 30 Cases With Flat-type Colorectal Polyps

Objective:To study the value of endoscopic mucosal resection (EMR) for flat-type colorectal polyps. Methods: Thirty-six lesions in 30 patients with flat-type colorectal polyps were resected by EMR after magnifying endoscope and mucosa staining,and the therapeutic effects and adverse reactions were evaluated. Results: The maximum diameter of 36 lesions was 0.8~2.5 cm (mean 1.4±0.5 cm),32 lesions of which were one-time complete resection and four lesions were piece EMR. Bleeding occurred in 3 cases,and the Argon Plasma Coagulation (APC) and electrocoagulation were taken to stop bleeding,1 case of delayed postoperative bleeding,metal clips was used to stop bleeding after treatment. The colonoscopy after a month in 30 patients showed wound healing,no recurrence and residual lesions were found in these patients followed up for 6~12 months (average 9.3 months). Conclusions: Colorectal flat-type polyps can be effectively treated by EMR,and the method is simple,less traumatic,but safe and worthy to be popularized.
