影像学评价胃镜下幽门括约肌切开治疗先天性肥厚性幽门狭窄无效

目的 探讨影像学检查对胃镜下幽门括约肌切开治疗先天性肥厚性幽门狭窄(CHPS)无效的病因诊断价值.方法 回顾性分析9例胃镜下治疗CHPS术后反复呕吐患者的超声检查特点,并与泛影葡胺胃肠造影、胃镜检查结果进行比较.结果超声检查能量化比较术前、术后的改变,动态观察幽门管的功能;泛影葡胺胃肠造影对引起呕吐的其他消化系统疾病诊断准确;胃镜能及早期、准确观察到黏膜的病变,并引导治疗.结论超声检查具有无创、准确性高及价廉等优点,可作为胃镜下幽门括约肌切开术治疗CHPS无效的首选影像学评价手段.

Imaging evaluation of ineffectiveness in congenital hypertrophic pyloric stenosis after endoscopic pyloric sphincterotomy

Objective To investigate the value of imaging assessmentfor the etiological diagnosis of congenital hypertrophic pyloric stenosis (CHPS) ineffectiveness after endoscopic pyloric sphincterotomy. Methods Nine patients with recurrent vomiting after endoscopic treatment of CHPS were retrospectively analyzed, and the ultrasound characteristics were reviewed and compared with the results of Meglumine Diatrizoate gastrointestinography and gastroscopy. Results Ultrasound could observe the changes before and after surgery and pyloric function dynamically. Meglumine Diatrizoate gastrointestinography could accurately diagnose other digestive system diseases that caused vomiting. Endoscopy could detect early mucosal lesions accurately and guide treatment. Conclusion Ultrasound can be used as the first choice to assess CHPS ineffectiveness after endoscopic pyloric sphincterotomy.
