To demonstrate esophageal varices barium sulfate suspensions must coat the lower esophagus for as long as 5 to 10 minutes. This study compared the ability of five barium sulfate preparations to resist disappearance by inadvertent swallowing. Three of the special preparations for esophageal examination, Esophatrast, Barosperse Esophageal Paste, and HD-5000 performed satisfactorily. Examiner skill, persistence, and careful technique are the most important factors in examining the lower esophagus. The authors' procedure for examination of the esophagus for varices is described. It takes into account position, time, phase of respiration, occasional use of drugs, and procedures to insure good coating and relaxation of the lower esophagus.
为了显示食管静脉曲张，硫酸钡混悬液必须在食管下段停留5至10分钟。本研究比较了五种硫酸钡制剂抵抗因误咽而消失的能力。三种用于食管检查的特殊制剂，即食管造影剂、食管钡剂糊剂和HD - 5000，表现令人满意。检查者的技能、坚持性和仔细的技术是检查食管下段最重要的因素。文中描述了作者检查食管静脉曲张的程序。该程序考虑了体位、时间、呼吸阶段、偶尔使用药物以及确保食管下段良好涂布和松弛的操作。
