Observation of portal circulation through superior mesenteric vein by enteric coated capsule of thallium-201

Journal Article:

Abstract

A new method of oral administration of an enteric coated capsule of /sup 201/Tl (/sup 201/Tl-capsule) was developed to evaluate the portal circulation through the superior mesenteric vein (SMV). The /sup 201/Tl-capsule was not collapsed in the artificial gastric juice, whereas it melted soon after soaking in the artificial intestinal juice. In a clinical trial of 42 cases, /sup 201/Tl was satisfactory released in the duodenum in 36 cases where clear liver images were observed except in 1 patient. Heart to liver ratio (HL) at 60 or 90 min after duodenal release of /sup 201/Tl was 0.32+-0.07 (mean +-1 s.d.) in normal controls, 0.34+-0.12 in chronic hepatitis, 0.31+-0.12 in acute hepatitis, 0.45+-0.13 in liver cirrhosis and 0.48+-0.32 in cirrhosis with hepatocellular carcinoma. In 11 patients who had both oral and rectal studies with /sup 201/Tl, 7 showed a high HL ratio of more than 0.8 in the rectal study but only 1 showed a similarly high ratio of 1.07 in the oral study. In the group of varied liver disorders we have studied so far, it was found that most of the SMV blood flowed into the liver and the degree of portal systemic shunting (PSS) from the SMV was  More>>

In the group of varied liver disorders we have studied so far, it was found that most of the SMV blood flowed into the liver and the degree of portal systemic shunting (PSS) from the SMV was much smaller compared to that from the inferior mesenteric vein. The present study with oral administration of the /sup 201/Tl-capsule was of value in understanding portal circulation through the SMV, however, this technique seemed of limited usefulness for evaluating overall pathologic PSS.}
