A case of adult idiopathic hypertropic pyloric stenosis whose radiographic study was repeatedly normal is presented. Only a functional test of gastric emptying disclosed the degree of outlet obstruction present. Vagotomy and pyloroplasty resulted in prolonged relief of obstructive symptoms and a return of the saline load test to normal. The saline load test may be of value when gastroduodenal x-rays or endoscopy do not reveal the cause or extent of gastric outlet obstruction.
本文报告一例成人特发性肥厚性幽门狭窄病例，其放射学检查结果反复正常。仅通过胃排空功能试验才揭示出存在的出口梗阻程度。迷走神经切断术和幽门成形术使梗阻症状得到长期缓解，盐水负荷试验结果恢复正常。当胃肠X线检查或内镜检查未揭示胃出口梗阻的病因或程度时，盐水负荷试验可能具有价值。
