Peroral traction-assisted natural orifice trans-anal flexible endoscopic rectosigmoidectomy followed by intracorporeal colorectal anastomosis in a live porcine model

Figure 2 Peroral traction-assisted transanal natural orifice trans-anal endoscopic surgery sigmoidectomy followed by intracorporeal colorectal end-to-end anastomosis under trans-gastric endoscopic guidance. A: A purse-string suture was placed around the top of the open proximal colonic segment after a stapler anvil was inserted; B: An endoloop was used to ligate the lateral rectostomy by endoscopy; C: The anvil was used to approach the stapler with the assistance of a rigid grasper; D: Endoscopic observation of the colorectal anastomotic tissue ring; E: View via laparotomy of the lower abdomen and pelvis showing colorectal end-to-end anastomosis; F: The resected sigmoid colon specimen.
