[Advantages of transanal approach in low rectal cancer resections].

Laparoscopic surgery is proven equal technique to open rectal surgery. Despite advantages, some problems in case of low rectal surgery are existing: visualization of the pelvis, securing safe distal resection margin, preparing single stapled rectal stump with safe conjunction to the colorectal anastomosis. Approximately 500 procedures have been performed worldwide until today by applying Transanal Total Mesorectal Excision (TaTME) technique, which evolved from a combination of laparoscopy and transanal approach. TaTME presents a solution to the low and mid-level rectal cases. The transanal path provides a better opportunity for preparing safe distal resection margin, an easier way for making a secure distal stump closure, and also offers perfect visualization even in the most difficult area, supporting the aim of nerve-sparing. We present a case, where we performed a synchronous laparoscopic and transanal TaTME resection of a down-sized low rectal tumor at 5 cm, after neoadjuvant radio-chemotherapy. To the best of our knowledge, this was the first case in Hungary, when TaTME was administered in a synchronous way.
