门脉高压病人常因食管曲张静脉破裂发生上消化道大出血。近年来,由于急诊内窥镜的广泛开展,发现有相当一部分门脉高压上消化道大出血并非食管曲张静脉破裂所致,而是来自急性胃粘膜损害。因门脉高压对胃粘膜的影响,门脉高压病人比一般人更易发生胃粘膜损害,其出血量比较大 Patients with portal hypertension often have upper gastrointestinal bleeding due to rupture of the esophageal varices. In recent years, due to the extensive implementation of emergency endoscopy, it was found that a considerable portion of portal hypertension with upper gastrointestinal bleeding is not caused by esophageal variceal rupture, but from acute gastric mucosal damage. Due to the impact of portal hypertension on the gastric mucosa, portal hypertension patients are more prone to gastric mucosal damage than the average person, the bleeding volume is relatively large
