先天性胆总管囊肿术后十二指肠胃返流的动态观察

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２４ｈ胃食管双ｐＨ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２０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

Dynamic Observation of Duodenogastric Reflux in Postoperative Patients with Congenital Choledochal Cyst

Objective:Two different dynamic methods was used to monitor the characteristics of duodenogastric reflux (DGR)in postoperative patients with congenital choledochal cyst. Methods:Twenty-four hour dynamic gastroesophageal double pH monitor and hepatobiliary scintigraphy were combined to observe the occurrence of DGR in 17 normal children and 20 patients following different treatment methods.Results:The DGR incidence in cystectomy-hepaticoduodenostomy procedure group is higher than that in cystectomy-hepaticojejunostomy procedure.Pathology DGR usually occurs in fast and supine situation. Conclusion:According to the incidence of DGR,cystectomy-hepaticojejunostomy procedure has better long-term results than hepaticoduodenostomy procedure. The combination of the two methods will greatly improve the senstivity and specificity for the diagnosis of DGR.
