Quantitative study of magnetic resonance imaging in common hepatic lesions / 中国普通外科杂志

ObjectiveTo evaluate the characteristics of MRI of common hepatic lesions by using measurement of T1,T2 and ADC on the MRI and DWI. MethodsMRI and DWI were obtained in 100 patients with common hepatic lesions, and T1,T2,ADCs and the ratios of the ADC of lesion/liver were estimated. (Results)Average T1,T2 and ADCs of hepatic lesions were as follows: hepatocellular carcinoma, (843.92167.75) ms , (73.9014.21) ms and(0.990.26)10~(-3)mm~2/s respectively; hepatic (metastasis), (946.89186.13) ms, (76.3919.76) ms and(1.170.32)10~(-3)mm~2/s (respectively); hepatic cavernous hemangioma, (1102.33213.12)ms, (142.3228.51) ms and (1.810.42)10~(-3)mm~2/s respectively; hepatic cyst, (1516.32617.84)ms ,(247.33112.52)ms and (3.110.38)10~(-3)mm~2/s respectively. The ratio of the ADC of lesion/liver:(hepatocellular) carcinoma was 0.890.17, and significantly lower than the ratio of hepatic metastases((1.27)0.21, P

Clinical features and surgical treatment of extrahepatic growing hepatocellular carcinoma / 中国普通外科杂志

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.

Heptocellular carcinoma with serum AFP level in 21?g/L to 200 ?g/L / 中国普通外科杂志

Objective To introduce clinical diagnostic specificity of hepatocellular carcinoma (HCC) with serum AFP level in 21*!?g/L to 200*!?g/L. Methods Making a literature summarizaton based on the papers review.Results and Conclusions (1) The AFP level more than 20*!?g/L can be used as a diagnostic criteria of HCC when existing liver space occuping lesion (SOL). (2) The clinical diagnostic criteria using AFP level more than 20 ?g/L instead of more than 200 ?g/L would be helpful to avoid misdiagnosis of HCC with the AFP level in 21 ?g/L to 200 ?g/L. (3) The Combination of AFP level more than 20 ?g/L with ultrasonography, CT scanning would have higher sensitivity and specificity than single diagnostic method.

Diagnosis and treatment of primary liver cancer with cancer thrombus of the bile duct / 中国普通外科杂志

Objective To study the diagnosis and treatment of primary liver cancer(PLC) with bile duct cancer thrombus (BDT). Methods The clinical data of 21 patients with PLC and BDT admitted in the past 8 years were analyzed retrospectively . Results The major clinical manifestations were the symptoms of primary liver cancer and obstructive jaundice. The correct diagnosis rate was 76.2% before operation. The diagnosis rate of B-us, CT, MRI, ERCP and PTC was 14.3%, 9.52%, 14.3%, 71.4% and 100% respectively. The operative procedures included hepatectomy with removal of BDT ( n =10), hepatectomy combined with extrahepatic bile duct resection ( n =5), thrombectomy through choledochotomy with TACE ( n =3), removal of BDT with HAI ( n =3). The 3,5-year survival rate were 43.20% and 24.60% respectively. Conclusions Multi-examinations should be applied in the diagnosis of PLC with BDT. The comprehensive therapy including surgery and other therapies must be adoptted for PLC with BDT.
