目的 :讨论肥厚性幽门狭窄的影像学表现及X线钡餐检查临床意义。材料与方法 :48例呕吐患儿分别行超声和X线钡餐检查 ,并与手术结果对照分析。结果 :48例患者超声诊断肥厚性幽门狭窄 ,47例经手术证实 ,1例X线钡餐检查及手术证实为胃窦部隔膜型狭窄。其中12例伴胃食管返流 ,2例伴食管裂孔疝。所有患者行幽门成形术后症状缓解或消失。结论 :超声和X线钡餐检查对于肥厚性幽门狭窄诊断均具有较高诊断准确性 ;钡餐检查并可同时发现胃食管返流及食管裂孔疝等疾病 ;超声和X线钡餐结合有助于明确诊断为手术提供依据。
Objective: To discuss the imaging findings of hypertrophic pyloric stenosis and the clinical significance of X-ray barium meal examination. Materials and Methods: Forty-eight children with vomiting were examined with sonography and X-ray barium meal respectively and compared with the results of surgery. Results: Forty-eight patients were diagnosed with hypertrophic pyloric stenosis by ultrasonography and 47 patients confirmed by operation. One case of X-ray barium meal examination and operation confirmed as antral ventricular septal stenosis. Among them, 12 cases had gastroesophageal reflux and 2 cases had hiatal hernia. All patients underwent pyloroplasty after symptom relief or disappearance. Conclusions: Ultrasonography and X-ray barium meal examination have high diagnostic accuracy for the diagnosis of hypertrophic pyloric stenosis; barium meal examination and simultaneous detection of gastroesophageal reflux disease and esophageal hiatal hernia and other diseases; combination of ultrasound and barium meal helps to confirm the diagnosis Provide the basis for surgery.
