Complete prevention of anastomotic leakage using total enteric flow diversion

Figure 3 Intraoperative operation diagram. A: Macroscopic aspect of a descending colostomy with ligation of supplying vessels at 1 cm above the anastomotic segment. Local ischaemia at the anastomotic site was created by ligating the supplying mesocolic vessels 1 cm above the anastomotic segment; B: Leakage test: After placing the tube, the balloon was infused with water to a pressure of 20 kPa. The water mixed with methylene blue did not leak into the proximal intestine.
