Abstract
Laparoscopic hepatectomy is considered a conventional method for treating benign and malignant liver diseases because it is a minimally invasive method. Despite its non-invasive aspect, bleeding and bile leakage occur in liver parenchyma tissue resection during the operation or in the post-operation period, indicating the requirement for high-grade hemostatic devices, such as ultrasonic surgical aspiration, bipolar electrocoagulation, etc. The lack of availability of these high-grade hemostatic devices prevents laparoscopic hepatectomy from becoming a generalized procedure in basic medical organizations. In view of the situation mentioned above, a suite of simple and easy hemostatic devices is developed in this protocol, which includes a harmonic scalpel, monopole electrocoagulation, and a single lumen catheter, to innovatively perform liver parenchyma tissue resection. First of all, the porta hepatis or hepatic pedicle is occluded intermittently by a single lumen catheter, followed by clamping for 15 min and releasing for 5 min. Subsequently, using the harmonic scalpel, clamping and crushing of the liver are done to cut off the hepatic parenchyma tissue and to reveal the intrahepatic arteries, veins, and bile ducts. Lastly, the bleeding spots are coagulated by using monopole electrocoagulation at each spot. Intrahepatic pipeline structures are then visible by using these methods, which could stop bleeding easily, reduce the incidence rate of bile leakage, and improve the safety and feasibility of laparoscopic hepatectomy. Therefore, the simple and easy hemostatic devices shown here are suitable for conducting procedures in primary medical institutions.
