Secretin was injected into a feeding or nonfeeding artery of a gastrinoma and blood samples were taken from the hepatic vein (HV) or a peripheral artery (PA) to measure the changes of serum immunoreactive gastrin concentration (IRG). The IRG in the HV rose within 40 seconds and in the PA rose within 60 seconds after the injection of secretin into a feeding(More)
Changes in arterial and hepatic venous blood ketone bodies were investigated following transcatheter hepatic artery embolization (THAE) in patients with hepatocellular carcinoma. Acetoacetate/ beta-hydroxybutyrate ratio (ketone body ratio) in arterial blood was positively correlated with those of hepatic venous blood (r = 0.960, p less than 0.001), which(More)
To establish useful predictors of the intrahepatic recurrence of hepatocellular carcinoma (HCC) after partial hepatectomy, retrospective analyses of clinical and pathologic factors were done in 112 of 206 patients treated by partial hepatectomy. The absence or presence of intrahepatic recurrence was confirmed by a follow-up study. Cancer-free survival rates(More)
An emergency transthoracic transection of the esophagus was performed on a 62 year old man for hematemesis caused by rupture of esophageal varices. Hepatic functional reserve of this patient was classified as Child C. Postoperative celiac arteriography revealed an arteriovenous fistula between a branch of the gastroduodenal artery and a branch of the(More)
Hepatocellular carcinoma (HCC) was classified into the three types of expansive type "Exp", mixed type "Mix" and infiltrative type "Inf" according to the preoperative angiographic characteristics, referred to clinicopathological features. "Exp" type had less incidence of accompanied portal venous invasion and daughter nodules in comparison to "Inf" type.(More)
We have already shown that gastrinomas release gastrin when stimulated with secretin in vitro. In order to ascertain whether this is true in vivo and whether the reaction is clinically useful in the localization of gastrinomas, secretin was injected into a feeding artery of the gastrinoma in four patients, and blood samples were taken from a peripheral(More)
From May 1982 till Nov. 1984, we performed 90 hepatic resection for primary or metastatic liver tumor. Preoperative transcatheter arterial embolization (TAE) was performed on 14 of them. All resected specimens of 14 cases were examined histologically. Effectiveness of TEA was estimated by the ratio of the necrotic area to the whole area of the tumor.(More)
Indications for limited hepatic resection in patients with hepatocellular carcinoma were evaluated by retrospective and clinicopathologic analysis of postoperative cases. Particular attention was paid to hepatic functional reserve and long-term prognosis. In our department, in order to estimate the hepatic functional reserve, indocyanine green clearance(More)
The clinicopathological features showing the malignancy of hepatocellular carcinoma were investigated by retrospectively analyzing the postoperative prognosis after hepatic resection. The long-term prognosis was stongly affected by the existence of portal tumor invasion or intrahepatic metastasis as indicated by the following results. The 3-year cumulative(More)
