Pharyngeal and upper esophageal sphincter (UES) manometry was performed in 15 patients with esophageal achalasia and compared with that in 10 healthy controls. Neither the pharyngeal contraction pressure nor the UES resting pressure were significantly different between the two groups, although the UES residual pressure in patients with achalasia was significantly increased compared with that in controls. Pneumatic dilatation of the lower esophageal sphincter (LES) was performed in these patients. After successful LES dilatation, the increased UES residual pressure in patients with esophageal achalasia decreased significantly. Our results suggest that UES relaxation in patients with esophageal achalasia is incomplete compared with that in healthy adults. This UES abnormality is not a primary defect but a secondary phenomenon.
对15例贲门失弛缓症患者进行了咽和食管上括约肌（UES）测压，并与10名健康对照者进行了比较。两组之间的咽收缩压和UES静息压均无显著差异，尽管贲门失弛缓症患者的UES残余压与对照组相比显著升高。对这些患者进行了食管下括约肌（LES）的气囊扩张术。LES扩张成功后，贲门失弛缓症患者升高的UES残余压显著降低。我们的结果表明，与健康成年人相比，贲门失弛缓症患者的UES松弛不完全。这种UES异常不是原发性缺陷，而是继发性现象。
