Computer-assisted electrocoagulation: bipolar vs. monopolar in the treatment of experimental canine gastric ulcer bleeding.

abstract：BACKGROUND & AIMS:Dilutional hyponatremia is a frequent complication of cirrhosis partly because of nonosmotic vasopressin release. No effective therapy exists for this complication. Therefore, we investigated the effects of VPA-985, an orally active vasopressin V2 receptor antagonist, in patients with cirrhosis and di...
