Aim: For many physicians who ordinarily treat patients with colonic diseases, colonoscopy is considered a prime study interest. Developments in colonoscopic equipment and methods have led to a large number of endoscopic diagnoses and treatment for colorectal neoplasms. The purpose of this investigation is to evaluate the efficacy and outcomes of endoscopic treatment for colorectal neoplastic lesions. Methods: From September 1999 to May 2003, 11 447 consecutive colonoscopic examinations in 9 864 patients were gathered; totaling 5 502 endoscopic treatments for colorectal neoplasms. Macroscopic characteristics of the neoplasms were classified into protruded (n = 3 953), sessile (n = 1402), lateral spreading tumor (n = 139) and depressed lesions (n = 8). Snare polypectomy was conducted in 3 984 lesions, hot forcep removal in 1 368 lesions, and endoscopic mucosal resection in 150 lesions. Results: Histological diagnoses were 4 596 neoplastic lesions (4 376 adenomas and 220 adenocarcinomas) and 906 non-neoplastic lesions (891 hyperplastic and 15 inflammatory polyps). For the adenocarcinoma group, 31 instances involved submucosal invasion or resection margin, who received further operations, while 13 surgical specimens discovered no residual tumors. Three perforations and 96 bleedings were found following endoscopic treatment. No procedure-related mortality was found and no recurrent malignancy was found after 14-56 mo follow-up. Conclusion: To lower the incidence and mortality of colorectal cancer, endoscopic treatment for colorectal neoplasms is a simple and safe procedure.
