第一阶段研究由吞钡造影中随机抽样的72例病人组成样本。所有病人均患有各种病因所致且较严重的慢性肝脏疾病。均在吞钡检查的三个月内做食管内窥镜检查。将X线检查结果与内窥镜表现做对照,以内窥镜检查作为参考,确定静脉曲张分度的X线定量标准。第二阶段研究为前瞻性研究,由47例病人组成,应用第一阶段研究使用的X线方法和得出的分度标准。该组亦在吞钡检查三个月内做了内窥镜检查。为了良好的涂抹食管粘膜,作者采用高密度
The first phase of the study consisted of a sample of 72 patients randomly selected from a barium swallow angiogram. All patients have a variety of causes and more serious chronic liver disease. Esophageal endoscopy was performed within three months of barium ingestion. The X-ray examination results and endoscopic performance as a reference to endoscopic examination as a reference to determine varicose vein indexing X-ray quantitative standards. The second phase of the study was a prospective study of 47 patients using the X-ray method and the resulting indexing criteria used in the first phase of the study. The group also performed endoscopy within three months of barium swallow examination. In order to smear esophageal mucosa, the author uses high density
