  Purpose

Intraoperative bleeding remains a major concern during liver resection. Pringle maneuver is the most frequently used method to occlude inflow blood of the liver.However, experimental and clinical studies have shown than even short periods of clamping produce some degree of ischemia-reperfusion injury that can result in hepatocellular damage,this damage being especially important in patients with abnormal liver parenchyma such as steatosis and cirrhosis. The aim of this study was to evaluate whether the use of selective vascular clamping should be generalized to HCC patients and help to reduce the ischemia-reperfusion injury.

Arms Assigned Interventions
Active Comparator: Pringle's Maneuver
Patients with HCC received Pringle's Maneuver in hepatectomy.
Procedure: Pringle's Maneuver
The entire hilar pedicle was encircled with a rubber tape to perform a Pringle maneuver with a tourniquet.
Other Name: Pringle's Maneuver group
Experimental: Hemihepatic vascular Clamping
Patients with HCC received Hemihepatic vascular Clamping in hepatectomy
Procedure: Hemihepatic vascular Clamping
The portal vein,hepatic artery ,and biliary duct were dissected in the hilum by opening the peritoneal fascia. Either the right or left portal pedicle was isolated and encircled with a tourniquet or clamped with Shatinsky clamp. Separate clamping of accessory left hepatic artery was performed when present in controlling the left hemihepatic portal traid.
Other Name: Hemihepatic vascular Clamping group
Experimental: portal vein occlusion
Patients with HCC received portal vein occlusion in hepatectomy
Procedure: Portal vein occlusion
The proper hepatic artery was dissected first from the duodenohepatic ligament, portal pedicle was blocked with a rubber encircled through the posterior wall of proper hepatic artery and the bottom of duodenohepatic ligament.When aberrant hepatic arteries emerging from the superior mesenteric artery are found in duodenohepatic ligament ,they should be dissected and kept unobstructed.
Other Name: Portal vein occlusion group

Detailed Description:

From recent animal studies, it can be easily concluded that I/R injury of the liver may be a significant factor, which can promote the primary liver tumor recurrence and metastasis. If it is a truth in human, there must be a big challenge to the Pringle maneuver which was adopted routinely in hepatectomy in the past years. Pringle maneuver during hepatic resection may do harm to the liver function, make the tumor cell more aggressive and tend to recurrence. It is suggested that further strategies may be needed for the prevention and treatment of I/R injury ,early and late recurrences.Selective hepatic vascular clamping (SVC)such as hemihepatic vascular occlusion have been used to minimize ischemic injury during liver surgery, especially in patients with abnormal liver parenchyma. However,these procedure used is likely to depend on the surgeon's training or preference rather than on objective data, there is not any further reported data or RCT studies conducted about the postoperative outcome ,especially liver function.To address these issues,we designed a prospective randomized controlled trial comparing the complete hepatic vascular clamping (Pringle maneuver) and selective hepatic vascular clamping ( portal vein or hemi-hepatic occlusion) in patients undergoing hepatectomy. The main objective was to compare the liver I/R injury of two procedures to the postoperative liver function. The secondary objective was to evaluate the feasibility, safety, efficacy, amount of hemorrhage,postoperative complications ,disease-free and overall survival rate of the 2 procedures.
