大量的临床和实验观察支持门脉高压作用于胃粘膜可导致一种不同于胃炎的特殊的病,变。经内窥镜注射硬化剂治疗食道静脉曲张是否引起胃粘膜进一步充血或门静脉高压性胃炎出血,目前尚不清楚。为此作者用激光-多普勒血流仪测定了硬化剂治疗前后胃粘膜血流(GMBF)的变化,以研究可能产生的微循环改变。15例连续的门脉高压病人接受硬化剂治疗。其中8例为酒精性肝硬化,7例为肝炎后
A large number of clinical and experimental observations supporting the role of portal hypertension in the gastric mucosa can lead to a particular disease different from gastritis. It is not clear whether endoscopic injection of sclerotherapy for esophageal varices causes further hyperemia in the gastric mucosa or portal hypertensive gastritis. To this end the authors measured the changes of gastric mucosal blood flow (GMBF) before and after the treatment with a laser-Doppler flowmetry to study possible microcirculation changes. Fifteen consecutive patients with portal hypertension received sclerotherapy. Of these, 8 were alcoholic cirrhosis and 7 were hepatitis
