Abstract

Transanal endoscopic microsurgery is a minimally invasive procedure for the pathologies in the rectum. Transanal endoscopic microsurgery
can be performed using a laparoscopic single port. In this study, we intended to represent our first case in which we used the singleport
laparoscopic transanal endoscopic microsurgery for the excision of a rectal polyp. The single port was incorporated into the anal canal and
then this port was fixed by sutures to the perianal area. The polyp was entirely resected with the help of standard and two angled
laparoscopic surgical instruments. There were no postoperative complications and the patient was discharged on the first postoperative
day. The histopathological examination revealed that focal high-grade dysplasia detected in the resection material surgical margins were
negative. As a result, resection of rectal polyp in the anal canal by applying single-port laparoscopic surgery with the help of hand tools was
found to be safe and feasible.
