ABSTRACT

Common technique which is used for trans-anal local excision is transanal endoscopic microsurgery. General concepts of transanal endoscopic surgery are also similar with single port operations. A single port device could provide the platform which is needed to insert trocars for placing laparocopic instruments while keeping the air in the rectal lumen during transanal local excision procedure. Hereby we described a technique for single port assisted trans-anal local excision by applying a manual air insufflator for excising a rectal remnant of a neuroendocrine tumor which remained after a polypectomy procedure.
