Gastro-oesophageal reflux and hiatal incompetence were analysed in 191 patients using a new radiographic contrast medium, polyiodostyrene, with the same density (1.0 g/cm3) as ordinary gastric contents, and correlated with supplementary oesophagoscopy and intraluminal pressure measurements. A normal hiatus seems to be an important protection against gastro-oesophageal reflux. An incompetent hiatus involves a real risk for oesophagitis. A low-density, low-viscosity contrast medium improves the roentgenologic diagnosis of gastro-oesophageal reflux.
采用一种新型造影剂聚碘苯乙烯（其密度与普通胃内容物相同，为1.0克/立方厘米）对191例患者进行胃食管反流和食管裂孔功能不全分析，并与辅助食管镜检查和腔内压力测量结果相关联。正常的食管裂孔似乎是预防胃食管反流的重要保护因素。食管裂孔功能不全确实存在食管炎风险。低密度、低粘度的造影剂可改善胃食管反流的放射学诊断。
