胃镜下球囊扩张术治疗小儿十二指肠膜式狭窄

Gastroscopic balloon dilation of duodenal stenosis in children

目的探讨胃镜下球囊扩张术治疗十二指肠膜式狭窄的疗效。方法回顾分析我院2012年1至12月应用胃镜下球囊扩张术治疗十二指肠膜式狭窄4例病例，其中男2例，女2例，年龄4～37个月。均有呕吐病史。手术方法：胃镜直视下应用球囊扩张管，经十二指肠膜式狭窄隔膜孔，先用10mm直径球囊扩张管扩张隔膜，依次增加扩张管直径，直至隔膜完全扩开。结果4例经胃镜下球囊扩张术均成功扩开隔膜，无出血、肠穿孔等并发症发生。随访6～16个月，4例患儿均正常进食，无呕吐、腹胀表现，生长发育正常。消化道碘水造影检查无狭窄表现，均显示通畅。结论胃镜下球囊扩张术治疗十二指肠膜式狭窄，效果良好，值得进一步研究并加以推广。

Objective To explore the efficacies of gastroscopic balloon dilation in the treatment of pediatric duodenal stenosis. Methods Four patients with duodenal stenosis from January 2012 to December 2012 were retrospectively analyzed. Duodenum was dilated by balloon under gastroscopy. Such complications as bleeding and intestinal perforation were observed. And the follow-up studies in- cluded clinical symptoms, dietary and growth （weight ~ height）, follow-up gastroscopy and iodine water angiography. Results The diameters of duodenal diaphragm hole expanded from 12 to 16 mrrk And neither retraction nor obstruction was observed during follow-up. All of them had a normal diet without vomiting or bloating. And their growth and development were similar to those of other same- age children. Conclusions Gastroscopic balloon dilation is an effective non-invasive treatment for pedi- atric duodenal stenosis patients.
