由于骨盆的解剖结构，当肿瘤离肛缘有一定距离时，很难在直肠内进行局部切除。因此，我们开发了一种新的微创肿瘤切除技术。直径40 mm的直肠镜可在气体扩张的直肠腔内进行立体控制下的肿瘤切除。全层切除术可达段性切除及端端吻合术。在选定的病例中，局部切除小直肠癌可视为适当的治疗。然而，大多数局部切除癌时，切除腺瘤的计划，术后组织学显示carcinoma.Since 1983年，我们已经对326例患者，274人已被纳入前瞻性临床试验。术后病理证实74例为癌。该技术的优点是：在气体扩张的直肠内立体放大视野，可以在难以到达的手术区域内进行精确的手术。在术后期间，最小的不适和疼痛导致住院时间短。
The anatomy of the pelvis makes it difficult to perform local excisions in the rectum when the tumor is some distance from the anal verge. We have, therefore, developed a new minimally invasive technique for tumor resection. A rectoscope with a 40-mm diameter permits tumor resection under stereoscopic control in the gas-dilated rectal cavity. Excisions in full-thickness technique up to segmental resections with end-to-end anastomosis can be performed.In selected cases, local excision of a small rectal cancer can be regarded as appropriate treatment. However, most local resections of carcinomas are performed when removal of an adenoma is planned, and the postoperative histology shows a carcinoma.Since 1983, we have operated on 326 patients, 274 who have been enrolled in a prospective clinical trial. Definitive histologic examination proved that 74 of these tumors were carcinomas. The rate of severe complications in patients with carcinomas was 9%, and the mortality rate was 0%.The advantages of this new technique are: The stereoscopic magnified view in the gas-dilated rectum allows precise surgery in an operative field that is otherwise difficult to reach. During the postoperative period, minimal discomfort and pain result in a short hospitalization.
