Portal flow steal occasionally persists even after the liver transplantation, which may reduce the portal flow and thus threaten the patients' outcome. Therefore, pre- and peri-operative detection of portal steal phenomenon requiring radiological or surgical interruption is essential for the liver transplantation candidates as well as for the recipients.

BACKGROUND AND AIMS: FibroScan(R) is a new medical device that noninvasively measures liver stiffness. The aim of this study was to assess the accuracy of the liver stiffness measurement by FibroScan(R) for making the diagnosis of liver fibrosis in patients with chronic viral hepatitis. METHODS: We studied 103 patients with chronic viral hepatitis B or C and they underwent FibroScan(R) and liver biopsy between October 2005 and August 2006. Liver fibrosis was staged on a 0-4 scale according to the Korean Society of Pathologists Scoring System. The diagnostic accuracy was assessed by analysis of the receiver operator characteristics (ROC). RESULTS: The liver stiffness was 3.5-57.1 kPa (mean: 11.8, SD: 8.9). The mean value of liver stiffness in each fibrosis stage group (F1, F2, F3 and F4) was 5.8+/-1.8 kPa, 11.3+/-6.8 kPa, 11.8+/-6.0 kPa and 23.4+/-16.5 kPa, respectively. Liver stiffness measured by FibroScan(R) showed reliable correlation with the liver fibrosis stage as confirmed by liver biopsy (r=0.56, p<0.001). The AUROC (95% CI) of > or = F2, > or = F3 and F4 was 0.93 (0.86-0.99), 0.72 (0.62-0.82) and 0.80 (0.67-0.92), respectively. The sensitivity and specificity of 7.5 kPa, which was the cutoff value for > or = F2, was 84% and 90%, respectively. CONCLUSIONS: FibroScan(R) is a reliable method for the diagnosis of significant fibrosis (> or =F2) and cirrhosis in patients with chronic liver disease. The liver stiffness measurement by FibroScan(R) showed good diagnostic performance for significant fibrosis.

BACKGROUND/AIMS: Transient elastography (Fibroscan, Echosens, France) is a new, simple, and non-invasive method to assess the degree of hepatic fibrosis by measuring liver stiffness. Recent reports have shown that liver stiffness measurement using Fibroscan allowed accurate prediction of hepatic fibrosis in patient with chronic hepatitis C. The aim of this study was to evaluate accuracy of Fibroscan for the detection of hepatic fibrosis in Korea with various etiologies of chronic liver disease by comparison with fibrosis assessed by histologic examination. METHODS: Fifty-four patients with chronic liver diseases, which were histologically confirmed within recent 6 months were enrolled. Etiologies were HBV, HCV infection, autoimmune hepatitis, and non alcoholic steatohepatitis. Hepatic fibrosis was graded on the basis of standard guideline proposed by the Korean Study Group for the Pathology of Digestive Diseases. RESULTS: Fibroscan values were significantly higher in F3 (16.96 kPa) and F4 (19.86 kPa) than others (p=0.003). Liver stiffness measurement was significantly correlated to the fibrosis stage (r=0.614, p<0.0001). CONCLUSIONS: Liver stiffness measurement by Fibroscan is a promising method for the assessment of hepatic fibrosis in chronic liver disease because it accompanies no complication.

BACKGROUND/AIMS: Bleeding from esophageal varices (EV) is a major cause of death in patients with liver cirrhosis. Endoscopic screening is recommended for diagnosing EV, but various noninvasive parameters can also be used to predict EV. The liver stiffness measurement (LSM), a noninvasive technique for estimating liver fibrosis, was recently reported to be strongly correlated with the hepatic venous pressure gradient. This study evaluated the usefulness of LSM for predicting the presence and size of EV in patients with cirrhosis. METHODS: The relationships of LSM with the presence and size of EV were analyzed in 112 patients with liver cirrhosis. Liver cirrhosis was diagnosed histologically or clinically. The presence and size of EV were assessed by endoscopy, and LSM was determined by the Fibroscan(R) technique. RESULTS: LSM was strongly correlated with the presence of EV (P<0.0001): the LSM value was 42.7+/-21.9 kPa (mean+/-standard deviation) in patients with EV (n=82) and 19.1+/-12.6 kPa in patients without EV (n=30). The area under the receiver operating characteristic curve was 0.818 (95% CI, 0.732-0.904) for predicting the presence of EV, and an LSM value of 19.7 kPa was predictive of the presence of EV with a sensitivity of 87%, a specificity of 70%, a PPV of 89%, and a NPV of 66%. However, there was a weak correlation between LSM and the size of EV. CONCLUSIONS: LSM is useful for predicting the presence of EV in patients with cirrhosis but not their size.

OBJECTIVETo evaluate the predictive value of portal vein flow rate preoperative for portal vein thrombosis (PVT) after periesophagastric devascularization in hepatitis B cirrhosis-related portal hypertension.
METHODSFrom January 2007 to July 2008, 45 patients with portal hypertension caused by hepatitis B cirrhosis were performed splenectomy with peri-esophagogastric devascularization in the same medical group in West China Hospital of Sichuan University. The portal vein flow rate and the diameter of portal vein were measured with doppler sonography respectively before and after the operation. At the same time, the level of PT and PLT were detected. The weight of spleens were measured after operation.
RESULTSThirteen cases suffered from PVT postoperatively. Portal vein flow rate was significantly lower in patients with PVT postoperation than that in patients without PVT (P < 0.01). In patients with PVT (n = 13) postoperation, the preoperative portal vein flow rate was (19.5 +/- 5.3) cm/s. Among the 13 cases, there were 12 cases whose flow rate were lower than 25 cm/s, and 1 case whose flow rate was 32. 3 cm/s; In patients without PVT (n = 32), the preoperative portal vein flow rate was (9.6 +/- 8.0) cm/s. In patients with lower rate (n = 17), the incidence rate of PVT was 70.6%; in patients with higher rate (n = 28), the incidence rate of PVT was 3.6%. The incidence rate of PVT in patients with lower rate was significantly lower than patients with higher rate (P < 0.01). The diameter of portal vein in patients with PVT was significantly wider than patients without PVT. The diameter of portal vein was negative correlative with the portal vein flow rate. The value 25 cm/s was of diagnostic efficiency, the sensitivity was 92.3%, and specificity was 70.6%.
CONCLUSIONSThe portal vein flow rate preoperative can be used as an early predictor of portal vein thrombosis after periesophagastric devascularization in hepatitis B cirrhosis-related portal hypertension to give a guide to clinical work.

We report on a case of a 57-year-old male who underwent a curative resection for hepatocellular carcinoma (HCC) with histological confirmation of a spontaneously necrotized tumor. Initial serum AFP level was 4,778 ng/mL. A 3.7 cm hyperechoic mass in segment 6 of the liver was observed on ultrasonography and dynamic contrast-enhanced liver MRI showed a 3.7x3.1 cm sized HCC. He was scheduled to undergo curative surgical resection under the clinical diagnosis of an early stage HCC (Barcelona Clinic Liver Cancer stage A). Without treatment, the serum AFP level declined rapidly to 50 ng/mL over five weeks. He underwent curative wedge resection of segment 6 of the liver. Histology revealed complete necrosis of the mass rimmed by inflamed fibrous capsule on a background of HBV-related cirrhosis with infiltration of lymphoplasma cells. Exact pathophysiology underlying this event is unknown. Among the proposed mechanisms of spontaneous neoplastic remission of HCC, circulatory disturbance and activation of host immune response offer the most scientific explanation for the complete histologic necrosis of HCC in the resected mass seen in our patient.

BACKGROUND/AIMS: This prospective study aimed to determine if Doppler ultrasonography can be representative of hepatic venous pressure gradient (HVPG) in assessing the severity of portal hypertension and response to drug reducing portal pressure. METHODS: The HVPG and the parameters of Doppler ultrasonography including portal venous velocity (PVV) and splenic venous velocity, the pulsatility and resistive index of hepatic, splenic and renal arteries were measured in 105 patients with liver cirrhosis. In 31 patients the changes of hepatic venous pressure gradient and portal venous velocity after administration of terlipressin were evaluated. The patients who showed a reduction in HVPG of more than 20% of the baseline were defined as responders to terlipressin. RESULTS: Any Doppler ultrasonographc parameters did not correlate with HVPG. Both HVPG and PVV showed a highly significant reduction after the administration of terlipressin(-28.3 +/- 3.9%, -31.2 +/- 2.2% respectively). However, PVV decreased significantly not only in responders(31.7 +/- 2.4%) but also in nonresponders(29.5 +/- 6.1%). CONCLUSION: Doppler ultrasonography can not be representative of HVPG in assessing the severity of portal hypertension and response to drug reducing portal pressure in liver cirrhosis.

Breast cancer is a rare disease in men. We report a case of 53-year-old obese male, with known cryptogenic cirrhosis and hepatocellular carcinoma, presenting a tender mass on left breast. He was diagnosed with invasive intraductal carcinoma, which was consistent with a sporadic lesion. On the basis of previous literatures, obesity can be regarded as a cause for breast cancer even in men. However, there has been inconsistent data about link between liver cirrhosis and male breast cancer, which can be due to heterogenity in the etiology of cirrhosis. Through this case, it can be postulated that the risk for male breast cancer may vary according to the etiology of cirrhosis.
