Portal hypertension is a serious complication of liver cirrhosis.<jats:italic> Objective<\/jats:italic>. To identify relevant endoscopic findings in patients with advanced cirrhosis and consecutive portal hypertension.<jats:italic> Methods<\/jats:italic>. This was a retrospective study of liver transplant candidates who underwent upper gastrointestinal endoscopy between April 2011 and November 2015.<jats:italic> Results<\/jats:italic>. A total of 1,045 upper endoscopies were analyzed. Portal hypertensive gastric and duodenal polyps were frequently observed and were associated with thrombocytopenia (p = 0.040; OR: 2.4, 95% CI 1.04\u20135.50), Child-Pugh score &gt; 6 (p = 0.033; OR: 2.3, 95% CI 1.07\u20134.92), Model for End Stage Liver Disease score &gt; 16 (p = 0.030; OR: 4.1, 95% CI 1.14\u201315.00), and previous rubber band ligation (p &lt; 0.001; OR = 5.2, 95% CI 2.5\u201310.7). These polyps often recurred after polypectomy; however, no malignant transformation occurred during the observational time until October 2017. The most common endoscopic finding was esophageal varices, observed in more than 90% of patients.<jats:italic> Conclusion<\/jats:italic>. Portal hypertensive polyposis is common in patients with advanced cirrhosis. Our data suggest that these polyps have benign characteristics.<\/jats:p>","DOI":"10.1155\/2018\/2182784","type":"journal-article","created":{"date-parts":[[2018,8,1]],"date-time":"2018-08-01T19:33:41Z","timestamp":1533152021000},"page":"1-7","source":"Crossref","is-referenced-by-count":17,"title":["Portal
