[Endoscopic obturation of esophagogastric varices with bucrylate. II. Morphologic study based on 12 autopsy cases].

Abstract

The authors report the results of postmortem histopathological studies in 12 patients who had been treated by endoscopic obliteration of esophagogastric varices with Bucrylate (isobutyl-2-cyanoacrylate). All patients had cirrhosis; 11 patients were Pugh classe C. Eleven patients had esophageal injections. Acute esophageal lesions were characterized by ulcerations in obliterated varices and diffusion of Bucrylate into the esophageal wall. Chronic lesions were characterized by disappearance of varices and Bucrylate, extending fibrosis of the esophageal wall and re-epithelialization of the mucosa. In one patient who had received gastric injections only, non ulcerated Bucrylate filled gastric varices were seen. Bucrylate seems to have a dual action on esophageal varices: immediate obliteration and acute necrosis of the vascular endothelium. Necrosis causes diffusion of Bucrylate through the esophageal wall, and later, secondary fibrosis whereas the product is progressively eliminated into the esophageal lumen.
