title: Transanal endoscopic microsurgery via TriPort Access System with no general anesthesia and without sphincter damage.
abstract: The aim of this study was to develop a less-invasive transanal endoscopic microsurgery (TEM) operative technique that could be applied in severely ill patients. Modified technique of TEM operation with use of the TriPort Access System in place of the operative rectoscope was designed. Harmonic scalpel and regular laparoscopic instruments were used. Resection of the rectal stump tumor was performed. A 71-year-old male patient with recurrent adenocarcinoma T2N0M0 in rectal stump and ASA 4 was operated using presented technique with good outcome. Total operating time was 25 minutes. There were no adverse events during or after the procedure. Patient was fully mobilized directly after the procedure. Proposed technique can be performed in severely ill patients as it avoids anal sphincter divulsion and therefore general anesthesia. Standard laparoscopic instruments can be used at no extra cost and no need for additional skills.
