Oesophageal emptying was studied with scintigraphy, radiography, and the acid clearing test (ACT) in 18 patients reporting dysphagia and previously operated on with fundoplication. Radiography with contrast medium, isodense with water, revealed abnormalities in either motility or emptying capacity in 39% (7/18). A A barium meal showed abnormalities--that is, a tight repair, disruption of the fundoplication, or recurrence of the hernia--in 56% (10/18). The ACT was prolonged in 40% (6/15) of the patients. Pathological findings at scintigraphy with a solid bolus were found in 67% (12/18). Even if scintigraphy with a solid bolus is the method that identifies the highest number of patients with impaired oesophageal function among the tests used, it cannot differentiate between functional and anatomical disorders. A barium meal examination is the method of choice when an anatomical disorder is suspected.
对18例有吞咽困难且曾接受过胃底折叠术的患者，采用闪烁扫描、放射造影及酸清除试验（ACT）对食管排空情况进行了研究。使用与水等密度的造影剂进行的放射造影显示，39%（7/18）的患者存在动力或排空能力异常。硫酸钡造影显示，56%（10/18）的患者存在异常情况，即修复过紧、胃底折叠术破裂或疝复发。40%（6/15）的患者ACT延长。使用固体食团进行闪烁扫描时，67%（12/18）的患者有病理表现。即使在所用检查方法中，使用固体食团进行闪烁扫描能识别出最多食管功能受损的患者，但它无法区分功能障碍和解剖学疾病。当怀疑存在解剖学疾病时，硫酸钡造影检查是首选方法。
