Since transanal endoscopic microsurgery (TEM) was introduced in the mid-1980s, it has been well established that the technique is a safe and effective method to excise adenomas of the rectum. It is also clear that rectal carcinomas can adequately be resected using TEM techniques if appropriate patient selection criteria are employed. Many of these lesions would have previously required a laparotomy for removal. In addition, removal of other lesions such as carcinoids, rectal schwannomas, and rectal endometriosis has been described [1, 2, 3, 4]. Currently, the spectrum of uses for TEM is mainly limited to those just mentioned. With respect to extended applications, all that is required is creative thinking.
Currently, there are only scattered mentions in the literature reporting the use of TEM for conditions other than the excision of rectal tumors. Salm et al.  retrospectively reviewed 1,900 TEM-assisted procedures performed in Germany at 57 centers—of these, only 2.9%...
