Intraoperative blood loss is a major concern during liver resection, and intraoperative blood transfusion is a significant
predictor of disease-free and overall survival after liver resection, whether opened or laparoscopic method. Pringle???s
maneuver is presently a useful method to reduce blood loss and decrease operative time. Generally, we performed Pringle???s
maneuver with Hemostatic forceps during liver resection of opened method. However, it is difficult to apply a sufficient and
effective Pringle???s maneuver under laparoscopic approach due to the narrow space. The aim of this study is to design a simple,
secure, and safe technique of intracorporeal Pringle???s maneuver to facilitate safer laparoscopic liver resection. The device of
loop was designed with two components, consisted of a lock and a plastic tube. The tip of the plastic tube was inserted into the
lesser sac and pulled through the foramen of Winslow, and the tip was then inserted into the lock, forming loop around hepatic
pedicle. The plastic tube was pulled to occlude the hepatic inflow and temporarily fixed with lock. Then, we would tighten the
lock with self-designed screwdriver to keep the loop tension. In animal experiments, we applied Doppler ultrasound to make
sure that blood flow was blocked completely. Our self-designed device intracorporeal Pringle???s maneuver can facilitate safer
laparoscopic liver resection.
