General rules for recording endoscopic findings of esophageal varices were initially proposed in 1980 and revised in 1991. These rules have widely been used in Japan and other countries. Recently, portal hypertensive gastropathy has been recognized as a distinct histological and functional entity. Endoscopic ultrasonography can clearly depict vascular structures around the esophageal wall in patients with portal hypertension. Owing to progress in medicine, we have updated and slightly modified the former rules. The revised rules are simpler and more straightforward than the former rules and include newly recognized findings of portal hypertensive gastropathy and a new classification for endoscopic ultrasonographic findings.

The purpose of this study was to retrospectively clarify the current status in Japan of TACE using Lipiodol together with anticancer agents to treat hepatocellular carcinoma (HCC). We retrospectively surveyed 4,659 (average annual total) procedures for HCC over the years 2002-2004 at 17 institutions included in the TACE Study Group of Japan. The survey included six questions that were related mainly to TACE and Lipiodol for HCC treatment. The most frequently applied among the 4,659 procedures at the 17 institutions were TACE (2,310; 50%) and local ablation (1,395; 30%). Five of the institutions applied 201-300 procedures and 4 applied 101-200. Lipiodol was used in "all procedures" and in "90% or more" at seven and nine institutions, respectively. Almost all institutions applied 4-6 (mean, 5) ml of Lipiodol during TACE to treat tumors 5 cm in diameter. In conclusion, this survey clarified that TACE using Lipiodol and anticancer agents is a popular option for HCC treatment in Japan.

A case of malignant epithelioid hemangioendothelioma of the liver in a 48-year-old woman with severe portal hypertension and marked deformity of the liver is presented. This woman had a history of mild liver dysfunction since the age of 30 years, and abdominal distention, esophageal varices, splenomegaly and ascites since October 1996. Imaging examinations revealed liver deformity with severe atrophy of the left lobe and the anterior segment of the right lobe. Celiac arteriography showed narrowing and upward deviation of the proper hepatic artery, and occlusion of the left and right anterior hepatic arteries. Since March 1997, hepatic venography showed stenosis in the right hepatic vein truncus. Budd-Chiari syndrome was clinically diagnosed. She died in June 1997. The autopsy disclosed massive tumor embolism in the left and right anterior portal branches, few in the hepatic artery, and occlusion of the left and right anterior hepatic arteries. The extensive tumor embolism resulted in portal hypertension, and atrophy of the left lobe. The anterior segment of the right lobe was probably caused by the occlusion of both the hepatic arteries and the portal veins. The posterior segment of the right lobe, without massive tumor embolism in its portal branch, appeared hypertrophic.
