食管功能失调常用的检查方法为食管测压术和放射性核素食管通过功能测定。食管测压是有创性技术,并非完全生理状态下的检测,且引起病人不适。食管通过的放射性核素检查的诊断意义尚有争论。作者设计了一项前瞻性研究,测定放射学食管通过时间(ROTT)。选择72例与胃肠道疾病无关的病人,其中男性37例,女性35例,年龄13～67岁。受试者均无胃肠道(包括口、咽)症状,也未使用影响食管运动功能的药物。
Esophageal dysfunction commonly used test methods for esophageal manometry and radionuclide esophageal function determination. Esophageal manometry is an invasive technique that is not completely physiologically tested and causes discomfort to the patient. The diagnostic significance of esophageal radionuclide examination is still controversial. The authors designed a prospective study to determine the radiologic transit time (ROTT). 72 patients with gastrointestinal diseases were selected, including 37 males and 35 females, aged 13 to 67 years. The subjects had no gastrointestinal (including mouth, pharynx) symptoms, nor the use of drugs that affect esophageal motor function.
