A transanal approach to rectal polyp and cancer excision is often an appropriate alternative to conventional rectal resection, and has a lower associated morbidity. There has been a steady evolution in the techniques of transanal surgery over the past 30 years. It started with traditional transanal excision and was revolutionized by introduction of transanal endoscopic microsurgery in early 1980s. Introduction of transanal minimally invasive surgery made it more accessible to surgeons around the world. Now robotic platforms are being tried in certain institutions. Concerns have been raised about recurrence rates of cancers with transanal approach and success of subsequent salvage operations.
经肛门途径切除直肠息肉和癌症通常是传统直肠切除术的合适替代方法，且相关发病率较低。在过去30年里，经肛门手术技术不断发展。它始于传统经肛门切除术，20世纪80年代初经肛门内镜显微手术的引入使其发生了变革。经肛门微创手术的引入使世界各地的外科医生更容易掌握该技术。现在，某些机构正在尝试使用机器人平台。人们对经肛门途径治疗癌症的复发率以及后续挽救手术的成功率表示担忧。
