Natural orifice transluminal endoscopic wedge hepatic resection with a water-jet hybrid knife in a non-survival porcine model

Figure 1 Colostomy on anterior wall of rectal junction and sigmoid colon. At the beginning of trans-annual natural orifice transluminal endoscopic surgery procedure, entry into the peritoneal cavity was via a 15-mm linear incision using the hook knife (cutting width set at 6 units and cutting interval set at 1 unit). The ideal access point was the junction of rectum and sigmoid colon at a distance of 15-20 cm away from the anus.
