Application of hemihepatic blood flow occlusion via portal plate in resection of liver cancer

Objective To investigate the application value and safety of hemihepatic blood flow occlusion via portal plate in resection of liver cancer.Methods According to different hemihepatic blood flow occlusion techniques during operation,64 patients performed on the resection of liver cancer were divided into two groups.The patients in group A were treated with hemihepatic blood flow occlusion via portal plate,while those in group B with Pringle hepatic blood flow occlusion.The operation-related conditions,postoperative liver function and complication incidence of patients in two groups were compared.Results The total time of blocking blood flow in group A was significantly longer than that in group B,while the postoperative hospital stays markedly shorter than group B.The levelsof postoperative alanine aminotransferase(ALT),albumin(Alb)and total bilirubin(TB)showed significant changes in patients of two groups compared with treatment before,but the above indicators of patients in group A nearly returned to the preoperative level,and the levels of ALT and TB 1,3 and 7 days after operation in group A were significantly lower than those in group B,while Alb level significantly higher than group B.There were no deaths in two groups.Conclusion Hemihepatic blood flow occlusion via portal plate can effectively reduce the liver damage,promote postoperative recovery of liver function,and has a low incidence of complications.Hence,it is an ideal method to control hepatic blood flow in resection of liver cancer.
