Narrowing of the esophageal lumen often exists for months before being noted by the patient. Screening tests for such lesions would be useful, if applicable to office use. A magnetic disc tablet (14 mm in diameter and 5 mm thick) was fashioned by hand using dental acrylic material to enclose the magnet with a smooth watertight sheath. A magnetic detector was held on the anterior abdominal wall 2.5 cm below the xiphoid cartilage and 2.5 cm to its left. A significant change in reading indicated that the tablet had reached the cardia of the stomach. The magnetic tablet was readily detected in 11 patients without organic narrowing. Our method attempts to detect narrowing of the esophageal lumen by use of a magnetic disc tablet. Perhaps this will be of clinical usefulness in detecting esophageal disease before symptoms become apparent.
食管腔狭窄在患者注意到之前通常已存在数月。如果适用于门诊，针对此类病变的筛查测试将很有用。使用牙科丙烯酸材料手工制作了一个直径14毫米、厚5毫米的磁片，用光滑的防水护套将磁铁包裹起来。将磁探测器放在剑突软骨下方2.5厘米及其左侧2.5厘米处的前腹壁上。读数的显著变化表明磁片已到达胃贲门。在11例无器质性狭窄的患者中，磁片很容易被检测到。我们的方法试图通过使用磁片来检测食管腔狭窄。也许这在症状出现之前检测食管疾病方面具有临床实用性。
