[Iatrogenic hemobilia: clinical manifestation, diagnosis and management].

In the last 4 years, we had 8 cases of iatrogenic massive bleeding from the biliary duct following operations on the liver and bile ducts. It seemed to us that it was not an infrequent complication. In this communication, the clinical manifestations, diagnosis and management of the complications were presented with special emphasis on the importance of angiography in the diagnosis of this condition. In this series, 6 cases were treated successfully by trans-catheter embolization. It is believed that embolization is safe, reliable, and should be the procedure of choice in the treatment of this complication.

[Ethanol for hepatic arterial embolization (experimental study)].

In this experiment, 27 dogs underwent hepatic arterial embolization (HAE) with 99% ethanol in 10 (group A), 75% ethanol in 10 (group B) and 60% ethanol in 7 (group C). By the laparotomy, catheter was inserted into hepatic artery and ethanol at dose of 0.3 ml/kg was injected within 20 seconds. Arterial angiography was taken before and after HAE. The dogs were sacrificed in 1, 2, 4, 8 weeks. Liver specimens were examined grossly and microscopically. Both A and B group showed satisfactory results of embolization, but 99% ethanol caused severe damage to hepatocytes, perisinusoidal area and bile ducts. Eight of 10 dogs died of hepatic failure and infection within two weeks. 75% ethanol mainly occluded the smaller arterial branches. Hepatocellular and biliary tract lesions were slight and reversible. All the animals survived normally except two. Group C had some mild and limited liver damage and scattering thrombosis which might result from intima lesion. This article also discusses the clinical availability of ethanol HAE.
