近几年来,研究焦点注意于门脉高压症病人胃粘膜的内镜和组织学表现。其表现特征计有中度或重度胃炎、出血性胃炎、糜烂性胃炎、急性胃病变和充血性胃病等。这些病变的重要性在于与10%～70%的门脉高压症患者出血发作有关。Papazian 等经内镜观察到红斑区被稀薄的黄色网状结构所镶嵌,他们称之为花斑结构,并且发现此特征比用食管静脉曲张诊断门脉高压更为敏感和特异。然而,早期的某项研究中。只注意到这个体征有高度特异性,但是敏感性极低,总的预期值只有70%。同样,胃粘膜标本活检所见的毛细血管扩张和膨胀,尽管被一些人认为有高度的预期价值,但另一些人却发现是没有特异性和诊断意义不大。因此,本文作者研究门脉高压病人胃粘膜的内镜和组织学表现的诊断敏感性和特异性。为了评估门脉高压症所致的胃粘膜表现的可靠性,作者研究了50例门脉高压症患者和1323 In recent years, research has focused on the endoscopic and histological findings of gastric mucosa in patients with portal hypertension. Its performance characteristics include moderate or severe gastritis, hemorrhagic gastritis, erosive gastritis, acute gastritis and congestive stomach. The importance of these lesions is related to bleeding in 10% to 70% of patients with portal hypertension. Papazian and other endoscopic observation of the erythema area is thin yellow network structure inlaid, they call the piebald structure, and found that this characteristic than with esophageal varices diagnosis of portal hypertension is more sensitive and specific. However, in a previous study. Only noticed that the signs of a high degree of specificity, but very low sensitivity, the total expected value of only 70%. Similarly, telangiectasias and dilations seen in biopsies of gastric mucosal specimens, although considered by some to be of high expected value, have been found to be nonspecific and of little diagnostic significance. Therefore, the authors investigated the diagnostic sensitivity and specificity of endoscopic and histologic findings of gastric mucosa in patients with portal hypertension. In order to assess the reliability of gastric mucosal manifestations due to portal hypertension, the authors studied 50 patients with portal hypertension and 1323
