Since Miles described the combined abdominoperineal resection in 1908, his operation<br>has been the standard treatment for carcinoma of the rectum.<br>There has been recent interest, however, in the use of sphincter-saving procedure for<br>rectal carcinoma. Lesions in the middle or upper rectum can be managed with low<br>anterior resection, but low rectal carcinomas require local excision. Since local excision<br>of the primary tumor does not remove the areas of lymphatic spread, either the risk of<br>metastases must be minimal or additional treatment must be adminisered to control<br>regional disease. And so, curative local excision is indicated in accurately selected cases<br>of distal rectal cancer. A diagnostic, preoperative protocol was performed to assess the<br>histologic grade of the tumor, the depth of penetration in the rectal wall and the<br>presence of positive lymph nodes or distant metastases.<br>Along with digital examination, preoperative tests includes anoscope and biopsy,<br>barium enema, chest x-ray, C-T scan, colonoscopy and rectal endosonography, Now we<br>report a case of early rectal cancer which was treated with transanal full-thickness Disc<br>excision.<br>
