"Nutcracker esophagus" is a newly described esophageal motor disorder seen in some patients with chest pain and/or dysphagia and characterized manometrically by normal primary peristalsis with distal contractions of high amplitude. The radiographic and manometric examinations in 20 patients with nutcracker esophagus were correlated. Normal primary peristalsis was observed radiographically in 16 patients, and a nonspecific motor disorder was diagnosed in the remaining four patients. Mild-to-severe nonspecific tertiary activity was seen in about half of the patients, esophageal wall thickness was normal. It is concluded that nutcracker esophagus is primarily a manometric diagnosis made in the appropriate clinical setting, and that the radiographic findings are normal or nonspecific.
“胡桃夹食管”是一种新描述的食管运动障碍，见于一些胸痛和/或吞咽困难患者，其测压特征为原发性蠕动正常，但远端收缩幅度高。对20例胡桃夹食管患者的影像学和测压检查结果进行了相关性分析。16例患者影像学检查显示原发性蠕动正常，其余4例诊断为非特异性运动障碍。约半数患者可见轻度至重度非特异性第三收缩波活动，食管壁厚度正常。结论是，胡桃夹食管主要是在适当临床背景下作出的测压诊断，影像学表现正常或非特异性。
