Abstract:
Transanal excision of rectal polyps with laparoscopic instrumentation and a single incision laparoscopic port is a novel technique that uses technology originally developed for abdominal procedures from the natural orifice of the rectum. Transanal endoscopic microsurgery (TEM) is a well established surgical approach for certain benign or early malignant lesions of the rectum, under specific indications. Our technique is a hybrid technique of transanal surgery, a reasonable method for polyp resection without the need of the sophisticated and expensive instrumentation of TEM which can be applied whenever endoscopic or conventional transanal surgical removal is not feasible.
