Results:  Among the 277 patients, the overall accuracy of EUS and MDCT for T staging was 74.7% and 76.9%, respectively. Among the 141 patients with visualized primary

lesions on MDCT, the overall accuracy of EUS and MDCT AP24534 in vivo for T staging was 61.7% and 63.8%, respectively. The overall accuracy for N staging was 66% and 62.8%, respectively. The performance of EUS and MDCT for large lesions and lesions at the cardia and angle had significantly lower accuracy than that of other groups. For EUS, the early gastric cancer lesions with ulcerative changes had significantly lower accuracy than those without ulcerative changes. Conclusions:  For the preoperative assessment of individual T and N staging in patients with gastric cancer, the accuracy of MDCT was close to that of EUS. Both EUS and MDCT are useful complementary modalities for the locoregional staging of gastric cancer. “
“Background and Aim:  Hepatocellular carcinoma (HCC) tends to metastasize to extrahepatic organs. Stomach involvement has been seldom reported and has always been considered as direct invasion. This study aims to propose a possible existing pathway for the hematogenous metastasis of HCC to the stomach. Methods:  Only seven cases with stomach involvement were found from 8267 HCC patients registered at our hospital between 2000 and 2007. Their laboratory data, the findings of computed

tomography and upper endoscopy, therapeutic procedures, such www.selleckchem.com/products/Sunitinib-Malate-(Sutent).html as esophageal variceal banding ligation (EVL), and transhepatic arterial embolization (TAE) were further studied.

Results:  All seven patients were male. Liver cirrhosis was found in six patients (6/7 = 85.7%), HCC with portal vein thrombosis (PVT) in six patients (6/7 = 85.7%), splenomegaly in five patients (5/7 = 71.4%) and esophageal varices in five patients (5/7 = 71.4%). Six patients underwent TAE and one patient underwent EVL before the development of HCC in the stomach. Four patients had HCC at the cardia, one patient at the anterior wall of the high body and two patients at the greater curvature of the high body, far away from the original HCC. 上海皓元医药股份有限公司 Six patients eventually developed distant metastasis. HCC with gastric metastasis developed 53–126 days after TAE in five patients and 74 days after EVL in one patient. Conclusions:  When cirrhotic patients with portal hypertension have HCC with PVT, a hematogenous pathway can exist for gastric metastasis of tumor thrombi involving hepatofugal flow to the stomach after TAE or EVL apart from the major pathway of direct invasion. “
“Idiopathic portal hypertension (IPH) is a rare cause of intrahepatic portal hypertension. Data on natural history and prognosis of IPH are limited. We sought to describe the complications and long-tem outcome of IPH by retrospectively studying 69 biopsy-proven cases of IPH. Mean duration of follow-up was 6.7 ± 4.6 years. All patients had evidence of portal hypertension (PH) at diagnosis, and 42% were symptomatic.
