ABSTRACT
Transanal endoscopic microsurgery is a minimally invasive technique for the treatment of rectal lesions which was introduced by Buess. In this report the first clinical experience of transanal endoscopic surgery was performed by a single incision laparoscopic surgical port adapted through the anal canal. In single port surgery, the single incision laparoscopic surgical port has to be stitched around anal orifice. There is no need to use a fixation apparatus. In transanal endoscopic microsurgery procedure, a rigid rectoscope 40 mm in diameter is introduced into the anus by stretching anal sphincter. A single incision laparoscopic surgical port can be disposed through the anal canal where there is no harmful cause because it is made an elastic. The dissection in the transanal endoscopic microsurgery procedure needs specific equipment to improve the surgery; however we could complete the surgical dissection using standard laparoscopic devices with articulated ones. The other factor makes single port surgery easier than transanal endoscopic microsurgery procedure is insufflation. It is easy and controlled way to be insufflated by a particular pump and cheaper than any insufflators. Furthermore, in the operating room, the patient's position on the table was not a limiting factor. As a conclusion, we report that for selected patients, single port surgery can be performed using a single incision laparoscopic surgical port as an adjusted surgical technique. It gives safe and feasible way to remove benign and malign polyps and tumors up to 20 cm in the rectum.
