S1914 Metaanalysis of Comparison of Shunt Patency and Clinical Outcomes Between Bare & Polytetrafluoroethylene (Ptfe) Stent in Transjugular Intrahepatic Portosystemic Shunt (Tips)

Abstract

A S L D A b st ra ct s and blood extravasation were the main histopathologic findings which had significantly increased following variceal obliteration. The morphometric study revealed significant increase (p<0.001) of the mean vascular area of ecstatic blood vessels in the gastric, duodenal and jejunal biopsies following variceal obliteration. Moreover, immunohistochemical expression of VEGF was, also, significantly increased (p<0.001) in the gastric, duodenal and jejunal biopsies after variceal obliteration. CONCLUSION: Portal hypertensive gastropathy and enteropathy are increased in frequency and severity after esophageal variceal obliteration.
