目的 :利用不同的二种动态检测方法研究不同术式的先天性胆总管囊肿术后病儿十二指肠胃返流的特点。方法 :采用 2 4h胃食管双 p H动态检测结合持续性核素静脉注射肝胆闪烁显像技术 ,检测 2 0例不同术式的先天性胆总管囊肿术后病儿及 17名正常儿十二指肠胃返流 (duodenogastric reflux,DGR)出现情况。结果 :二种术式中囊肿切除 ,肝总管十二指肠吻合组 (H- D吻合组 ) DGR发生率高于囊肿切除 ,肝总管空肠 Roux- Y吻合组。病理性DGR多发生于空腹卧位。结论 :从术后 DGR发生率来看 ,囊肿切除 ,肝总管空肠 Roux- Y吻合组的远期效果优于后者 ,二种动态检测方法结合应用能提高诊断的灵敏度和特异性。
OBJECTIVE: To study the characteristics of duodenogastric reflux in children with congenital choledochal cysts of different surgical procedures by using two different dynamic detection methods. Methods: Twenty-four cases of congenital choledochal cyst postoperative children and 17 normal children twelve fingers were enrolled in this study. The 24 h gastroesophageal varices biopsies combined with continuous nuclide injection of hepatobiliary scintigraphy were performed. The occurrence of duodenogastric reflux (DGR). Results: The incidence of DGR was significantly higher in HCC duodenum anastomosis group than that in cyst excision and Roux-Y hepaticojejunostomy group. Pathological DGR occurred in fasting decubitus. Conclusion: The postoperative DGR incidence, cyst excision, Roux-Y hepatic duct jejunostomy group long-term effect is better than the latter, two dynamic detection methods combined with the application can improve the diagnostic sensitivity and specificity.
