Transanal endoscopic microsurgery was introduced by Buess and co-workers in 1984 for transanal removal of tumours up to 20 cm above anus. In the present study, 18 transmural and two mucosal resections were performed for rectal adenomas (16) and early rectal cancer (4). Median operation time was 85 minutes (55-140 minutes) and the median postoperative stay in hospital was 3 days (1-5). All tumours were removed radically and in none was there tumour involvement of the resection margin. There were no serious complications. After a median observation time of 10 months (1-17 months) there have been no recurrences. Functional results are excellent; none of the patients have developed incontinence. It is concluded that transanal endoscopic microsurgery (TEM) is an adequate method for removal of benign rectal tumours and, in selected cases, early rectal cancer.
经肛门内镜显微手术由布斯及其同事于1984年引入，用于经肛门切除距肛门20厘米以上的肿瘤。在本研究中，对直肠腺瘤（16例）和早期直肠癌（4例）进行了18例全层切除和2例黏膜切除。中位手术时间为85分钟（55 - 140分钟），中位术后住院时间为3天（1 - 5天）。所有肿瘤均被根治性切除，且切缘均无肿瘤累及。无严重并发症。中位观察时间为10个月（1 - 17个月），无复发情况。功能结果极佳；无患者出现失禁。结论是经肛门内镜显微手术（TEM）是切除良性直肠肿瘤以及在特定病例中切除早期直肠癌的一种合适方法。
