Abstract
Transanal endoscopic microsurgery (TEM) presents a minimally invasive procedure for local removal of large adenomas as well as early carcinomas of the rectum. 57 surgical departments/clinics, which practice this method in Germany were asked about their experience. 44 questionnaires were evaluated. Indications for the 1,900 recorded operations were 1,411 adenomas, 433 carcinomas (curative intention: 286; palliative intention: 147), and 56 other procedures. The conversion rate to laparotomy was dependent on the experience with this surgical method (1.2%-11.6%). A radical rectal resection as a second step was performed in 5.7% of patients in the case of advanced carcinoma in the histologic examination of the specimen. Complications appeared in 120 patients (6.3%), 77 patients (4.0%) recovered with conservative treatment, and 43 (2.3%) had to undergo surgery. The mortality rate was 0.2% (3/1,900 pts).
