METHODS： A total of 140 previously untreated cases of HCC were enrolled in this study from 1988 to 2002. The inclusion criteria were： a solitary tumor less than 4 cm in diameter or multiple tumors, fewer than four in number and less than 3 cm in diameter, without extrahepatic metastasis or vessel invasion. As general principles for the treatment of HCC, the patients underwent transcatheter arterial chemoembolization （TACE） prior to PEIT. After the initial treatment of the patients, ultrasonography and computed tomography were performed, and measurement of serum levels of α- fetoprotein （AFP） was determined. When tumor recurrences were detected, PEIT and/or TACE were repeated whenever the hepatic functional reserve of the patient permitted. We then analyzed the variables that could influence prognosis, including tumor size and number, the serum levels of AFP, the parameters of hepatic function （albumin, bilirubin, ALT, hepaplastin test, platelet number, and indocyanine green retention at 15 rain [ICG-R15]）, combined therapy with TACE, distant recurrence, and local recurrence. RESULTS： Univariate analysis identified the ICG test, serum levels of AFP and albumin, tumor size and number, and local recurrence, but not distant recurrence, as significant prognostic variables. In multivariate analysis using those five parameters, the ICG test, tumor size, tumor number, and local recurrence were identified as significant prognostic factors. In both univariate and multivariate analyses, the relative risk for the ICG test was the highest, followed by local recurrence. CONCLUSION： We found that local recurrence is an independent prognostic factor of HCC, indicating that achieving complete treatment for HCC on first treatment is important for improving the prognosis of patients with HCC. 2005 The WJG Press and Elsevier Inc.

Endoscopic ultrasound (EUS) is proposed to be a safe first line test of choice in the majority of patients. When interventions are needed to remove biliary stones, evaluate sphincter of Oddi or pancreas divisum, endoscopic retrograde cholangiopancreatography (ERCP) is recommended. Magnetic resonance cholangiopancreatography (MRCP) can be a suitable alternative from a diagnostic standpoint although may not be widely available. Finally, genetic testing is increasingly used to detect certain mutations that are associated with this diagnosis.展开更多

The first case had a mild pain in right upper quadrant of the abdomen; the second had no obvious symptoms. Physical examination revealed nothing abnormal. Both of them were diagnosed by magnetic resonance imaging angiography (MRA). One of the aneurysms was located at the main portal vein, the other, at the confluence of the superior mesenteric vein and the splenic vein, and these two places are exactly the most common locations of the extrahepatic portal vein aneurysm reported in the literature (30.7% each site). The first case underwent aneurysmorrhaphy and the second case, aneurysm resection with splenectomy. Both of them recovered soon after the operation, and the symptom of the first case was greatly alleviated. During the follow-up of half a year, no complication and adverse effect of surgical intervention was found and the color Doppler ultrasonography revealed no recurrence of the aneurysmal dilation. We suggest that surgical intervention can alleviate the symptom of the extrahepatic portal vein aneurysm and prevent its complications effectively and safely for low risk patients.展开更多
