In our experience sepsis and hemorrhage are most often the result of leakage from the pancreaticojejunal anastomosis. In some cases this is due to the development of acute pancreatitis in the pancreatic tail. As discussed above, the only solution to this vicious cycle is sometimes surgical removal of the residual pancreas. If the gastric pH is kept elevated by antacid therapy, bleeding due to gastric ulcer- ation is rare. It can be prevented by dissecting these two vital structures with care and precision.

Pretied ligatures are best used to secure the stump of a structure that Pretied endoscopic suture ligatures are available and useful has already been divided or to ligate the base of an appendix. They are commonly loaded with continuity because you must be able to pass the loop over the chromic catgut because this material swells slightly as it structure to be ligated. As the loop comes into contact with tissue, it absorbs water and softens, becoming limp and therefore much more difficult to handle. Avoid this problem by keeping the loop away from tissue until you are ready to close it. Pass a grasper through another port and pass it through the loop of the pretied ligature (Fig. The loop is quite large, and drawing up on the tail to make the loop slightly smaller may facilitate this maneuver. Once the stump is surrounded, place the tip of the knot pusher against the base exactly where you want the knot to sit. Slowly tighten the loop while maintaining slight tension on the stump with the grasper (Fig. Withdraw the knot pusher through the trocar and pass endoscopic scissors down to cut the ligature.
