Transanal endoscopic microsurgery (TEM) is performed with the use of a complex operative system, which allows the application of all surgical techniques for dissection and suturing inside the rectal cavity up to a height of 20 cm from the dentate line. Gas dilation and stereoscopic vision give an optimal overview during the procedure. In sessile adenomas and carcinomas within the region of the extraperitoneal rectum, full thickness excision is the standard procedure. The postoperative course is completely painless in all excisions at some distance from the dentate line. The complication rate is low compared with other procedures and the recurrence rate in sessile adenomas (3.5%) lower than in conventional surgery as a result of the precise dissection which is possible under the magnified stereoscopic vision. In PT1 low risk cancer we found one recurrence in 29 patients.
经肛门内镜显微手术（TEM）是使用一种复杂的操作系统进行的，该系统允许应用所有手术技术在直肠腔内距齿状线20厘米的高度范围内进行解剖和缝合。气体扩张和立体视觉在手术过程中提供了最佳的视野。对于腹膜外直肠区域内的无蒂腺瘤和癌，全层切除是标准手术。在距齿状线一定距离处进行的所有切除手术中，术后过程完全无痛。与其他手术相比，并发症发生率较低，并且由于在放大的立体视觉下可以进行精确解剖，无蒂腺瘤的复发率（3.5%）低于传统手术。在PT1低风险癌症患者中，我们在29例患者中发现1例复发。
