目前对食管静脉曲张破裂出血的原因仍了解甚少。有二种较为流行的说法:(1)因胃酸返流致食管粘膜糜烂出血;(2)因门静脉压力增高使粘膜下血管扩张破裂出血。有的作者经过活检和尸检研究,发现静脉曲张病人伴有食管炎,也有作者经实验研究认为仅仅静水压的改变不是出血的唯一原因。本文作者对食管静脉曲张破裂出血病人作食管横断术。将切下的食管环作垒层组织学检查,从而估价食管炎存在与否及其程度,并研究粘膜上皮内表浅的血管与出血的关系。作者对31例不同原因引起的门脉高压患者的食管环按一定标准制成全层的组织片,每例病人随机选择6
The cause of esophageal variceal bleeding is still poorly understood. There are two more popular statement: (1) due to gastric acid reflux esophageal mucosal erosion bleeding; (2) due to increased portal pressure to submucosal blood vessels rupture bleeding. Some authors after biopsy and autopsy studies found that patients with varicose veins associated with esophagitis, but also the author of experimental studies that only hydrostatic pressure change is not the only cause of bleeding. The author of the esophageal variceal bleeding for esophageal transection. The cut esophageal ring base layer histological examination, so as to assess the presence and extent of esophagitis and its extent, and to study the superficial mucosal blood vessels and bleeding relationship. The author of 31 cases of portal hypertension caused by esophageal ring of patients with a certain standard made of full-thickness tissue slices, each patient was randomly selected 6
