causes of upper gastrointestinal bleeding in patients with esophageal varices report of 161 nonalcholic cases

ABSTRACT

Introduction: It is generally appreciated and continues to be cited in standard textbooks of medicine that the source of Upper gastrointestinal bleeding [UGIB] in-patients with Esophageal Varices [EV] is usually nonvariceal. Although some recent reports are not in agreement with this conclusion, these reports come from western countries in which ethanol is the leading cause of cirrhosis and [EV]. Alcohol per se has many acute and chronic effects on esophagogastroduodernal mucosa, which may be a source of [UGIB]. Therefore conclusions regarding the source of [UGIB] in these patients may not be necessarily true in nonalcoholics with portal hypertension [PH] and [EV]
