Objective: Augmenter of liver regeneration cloned from liver of weaning rat is a novel hepatic stimulator. It was reported that ALR mRNA expression was correlated with DNA synthesis of hepatocytes after partial hepatectomy, and could significantly promote the survial rate of intoxicated hepatitis rats.

The uncovered tracts and the liver wound surface were managed by some of the methods combined such as high frequency electrocoagulation, titanium clamp, suture, hemostatic gauze oppression, argon-beam coagulation, protein glue adherence, and Endo-GIA switcher. The total operative outcome, operating time, blood loss, postoperative complications and postoperative hospital stay were summarized in order to assess feasibility and safety of the clinical laparoscopic liver resection.Results: 1. Laparoscopic liver resection with clamp dissection method needs only the ordinary laparoscopic equipment. It has a low cost but causes a little more bleeding. 2. Laparoscopic liver resection operated by microwave tissue coagulation method had very little bleeding when dissecting hepatic parenchyma. The operative field is clear and the cost is low. It is a safe, convenient and effective method. 3. Ultrasound dissector is a relatively ideal appliance for laparoscopic liver resection at present because ofless bleeding during operation. But the speed is slow thus prolongs the operation time. Its separating intensity is not strong enough, and it can only be applied to patients without hepatic cirrhosis. 4. Ligsure has clamp dissection and electrocoagulation functions. It can carbonize hepatic tissue including the tracts whose diameters are less than 7mm. It has some advantage in dissecting. However, it has the shortcomings of the clamp dissector during coagulating. 5. Hand-assisted laparoscopic liver resection can make use of the flexibility and feeling of the operators left hand.

Methods: 1. Experimental laparoscopic liver resection: We selected pigs as experimental models aiming to approach human beings physiological and anatomical condition. After CO2 pneumoperitoneum was established, the ligaments around liver were dissociated. Livers were cut off by the methods such as clamp dissection, microwave tissue coagulator, ultrasound dissector, Ligsure dissection, hand-assisted, short abdominal incision laparoscopy-assisted, and Endo-GIA switcher. The operation time and bleeding volume were compared between different methods of laparoscopic liver resection. The advantages and limitations of different methods were summarized. 2. Clinical laparoscopic liver resection: 15 cases with tumors in segment V of anterior right lobe or segments II, III of left lateral lobe or segment IV of left internal lobe were selected in this study. The liver diseases included hepatocellular cancer, hepatic cavernous hemangioma and hepatic focal nodular hyperplasia. The ligaments around liver were dissociated after CO2 pneumoperitoneum established. Laparoscopic liver resection were carried out by some of the methods combined such as clamp dissection, microwave tissue coagulator, hand-assisted, short abdominal incision laparoscopy-assisted, ultrasound dissector, rotation and suction dissector.

The faciform ligament is an important sign of laparoscopic liver surgery and a way of collateral circulation of liver. The superior liver artery found and named in this research can be an important sign to judge the position of hepatic vein. The operation pathway by cutting down the perihepatic ligament next to the superior border of liver is a quick way with little blood. It is difficult to hurt diaphragm and hepatic vein, and the secundum porta hepatic can be showed clearly. As a rule, we break the hepatic vein in the hepatic parenchyma on laparoscopic hepatectomy. But in some situation, extrahepatic treatment was used.
