New approaches in laparoscopic surgery for colorectal diseases: The totally laparoscopic and single-incision approaches

Figure 2 Efficient purse-string stapling technique. A: A semi-circumferential colotomy is performed at the colonic wall just proximal to the forceps; B: Anvil insertion into the colon via a semi-circumferential colotomy: An anvil with suture is held by a grasper and fully inserted into the proximal colon; C: The accompanying needle is advanced through the anterior colonic wall; D: The suture is pulled out of the colon until all knots are completely exposed; E: While pulling the suture to the right side horizontally, the colon is clamped using a linear stapling device with disposable gastrointestinal cartridge; F: The colon is then transected by firing the instrument to secure the anvil on the colonic stump.
