ABSTRACT
Objective To evaluate the effect of application of combined hemihepatic inflow and hepatic veins occlusion in major liver resection.Methods The clinical data of 46 cases of large hepatic carcinoma who underwent liver resection were surveyed retrospectively.The hepatic pedicle of affected side and hepatic veins were dissected and controlled initially,then hepatectomy was performed under the condition of vascular exclusion of the affected side of liver.Results All the 46 cases suffered from hepatocellular carcinoma.The average size of the tumors was 8.3 cm(6-15 cm) in diameter.One main hepatic vein was invaded by tumor in 20 cases and 2 main hepatic veins were invaded by tumor in 14 cases.Among the 46 hepatectomies,right hemihepatectomy was performed in 16,right posterior lobe hepatectomy in 14,and left hemihepatectomy in 16 cases.The mean occlusion time of the hemihepatic pedicle was 30 min(10-45 min),and occlusion time of the hepatic veins was 20 min(10-30 min).The average blood loss was 540 ml(300-1 500 mL).Postoperative complications occurred in 14 cases,and all recovered after treatment.There was no mortality in this series.Conclusions Combined hemihepatic inflow and hepatic veins occlusion in major hepatectomy is a safe,effective and practical vascular exclusion method which can effectively reduce the blood loss and the incidence of the liver function failure.
ABSTRACT
Objective To evaluate the clinical values of selective hemihepatic vascular occlusion in hepatectomy for large hepatocellular carcinomas.Methods Forty patients with large hepatocellular carcinomas who underwent hepatectomy with selective hepatic inflow and outflow occlusion of tumor-bearing liver were retrospectively analyzed.Results All the 40 patients underwent hepatectomy successfully.The blood losts during the operation was 100-800 mL(average 360 mL).The operation time was 90-150 min(average 116 min).Intraoperative blood transfusion was not performed in twenty-five patients.All patients recovered completely and were discharged without liver function failure or other severe complications.There was no perioperative death.Conclusions Selective hemihepatic vascular occlusion in hepatectomy for large hepatocellular carcinomas is a safe and effective method with advantages of controlling hemorrhage,decreasing liver damage and gut barrier injury,avoiding air embolism and preventing metastasis.

ABSTRACT
Objective To study the clinical characteristics, diagnosis and treatment of extrahepatic growing hepatocellular carcinoma(HCC). Methods The clinical data of 11 patients with extrahepatic growing HCC were analysed retrospectively. Results The mean diameter of the tumors was (12.4?4.3)cm.All the tumors in the 11 patients had complete capsule formation. The numbers of tumors located in the left, right and caudate lobe of the liver were 6,3 and 2 respectively. Surgical treatment included segmentectomy in 6 cases , lobectomy in 4 cases, and unresectable in 1 case. The 1-, 2-, and 3-year survival rates were 80.1%,62.3%, and 47.6% respectively. Conclusions Although the size of extrahepatic growing HCC is large,the resection rate is high and prognosis is good. The resection of hepatic segments or lobes containing the lesion should be done in radical operation of this tumors.
ABSTRACT
Objective To improve the recognition of intrahepatic biliary cystadenoma.Methods The clinical manifestations,radiologic features,diagnosis and surgical treatment of 18 patients with intrahepatic biliary cystadenomaadmitted in our hospital during the recent 8 years were retrospectively analyzed.Results Four cases were discovered by general medical examination,while the other 14 patients had varying symptoms that included right upper abdominal discomfort or pain in 11 cases,abdominal mass in 3 cases,and jaundice accompaniedby fever in 2 cases.B ultrasound and CT scan showed intrahepatic cystic occupying lesions consistingof multilocular or single cyst,and usually with papillary structures in the cyst wall.All of 18 cases received surgical resection.The patholgic dingnosis was intrahepatic biliary cystadenoma in all the 18 cases,and 6 of them showed malignant change.The average survival time of maligmant patients was 35(27-58)months.Conclusions Preoperative diagnosis of intrahepatic biliary cystadenoma is difficult.Intrahepatic biliarycystadenoma is easy to develop into cystadenocarcinoma.Early surgical resection is necessary,and can effectively prevent recurrence or malignant transformation.
ABSTRACT
Objective To investigate the feasibility and significance of the re-operation for patients with recurrent primary liver cancer.Methods The clinical data of 58 patients with post-operative recurrence after initial operation for primary liver cancer in our hospital from January 2003 to December 2008 were analyzed.They were divided into re-operation group and the other treatment group,and the 1-and 3-year survival rates were compared.Results The 23 cases of re-operation group were all treated by local radical resection plus hepatic arterial chemotherapy pump implantation,and postoperative chemotherapy was given via hepatic artery chemoembolization pump line.The 35 patients of the other treatment group underwent radiofrequency ablation plus transcatheter hepatic arterial chemoembolization via femoral artery.The 1-and 3-year survival rates in re-operation group was 100% and 82.6% respectively,which was significantly higher than that of the other treatment group(82.9% and 45.7% respectively).Conclusions Re-operation is the treatment of choice for patients with tumor recrrrencr after radical resection of primary liver cancer,provided that the conditions are suitable and the timing of operation is appropriate.
