Epidemiology and endoscopic treatment of portal hypertension associated with ectopic varices / 中国内镜杂志

ABSTRACT

Portal hypertension (PH) was defined as an increase in portal pressure caused by various etiologies. The formation of portosystemic collateral circulation was a compensatory form of PH. Gastrointestinal varices were one of the clinical manifestations of PH, and which clould be broadly divided into esophageal varices (EV), gastric varices (GV) and ectopic varices (EcV). At present, it is found that EcV has difficulty in diagnosis, large amount of bleeding, difficulty in hemostasis and poor prognosis. So far, the study of EcV is very limited. There was no guideline and expert consensus on EcV treatment. This review will focus on the epidemiological features of EcV and the research status of endoscopic treatment.
