门脉高压(PHT)时常并发胃粘膜病变(GML),其发生率在50％以上,有20％～40％的PHT病人的上消化道出血(UGIB)源于GML。其包括急性溃疡、糜烂,类似淤点的多发性损害和弥漫性、出血性胃炎等。它既可引起致命性的上消化道大出血,也可发生缓慢,隐袭性失血而导致贫血。故近年来国内外对此方面的研究日益增多。 Gastrointestinal hypertension (PHT) often complicated by gastric mucosal lesions (GML), the incidence of more than 50%, 20% to 40% of PHT patients with upper gastrointestinal bleeding (UGIB) from GML. It includes acute ulcers, erosion, multiple lesions similar to bruising and diffuse, hemorrhagic gastritis and so on. It can cause fatal upper gastrointestinal bleeding, can also occur slowly, insidious blood loss and lead to anemia. In recent years, there are increasing researches in this area at home and abroad.
