title: [Effect of porto-azygous disconnection with or without low esophageal transection on esophageal varices and portal pressure].
abstract: 73 cases of cirrhotic portal hypertension treated in 4 years period (1982-1986) were followed by endoscope. Varices showed very little chance to disappear completely, and little difference in results between porto-azygous disconnection and that in combination with lower esophageal transection. The pressure of disconnected coronary vein on stomach side showed considerable elevation than that before and also in combination with lower esophageal transection. Continuous observation of portal pressure changes during and after operation for 4 days showed variations of amplitude suggesting redistribution of portal circulation. Judging from the series of postoperative events in follow-up, particularly rebleeding from recurrence of varices, there was renewed collateral circulation developed in the area of porto-azygous connection irrespective of the means of interruptions.
