【摘要】 用９９ｍＴｃ亚氨基二乙酸（ＥＨＩＤＡ）肝胆显像诊断胆管囊肿并评价术后胆道功能状况，对１８例临床大多以腹痛、黄疸或腹部包块为主要症状的患儿行９９ｍＴｃＥＨＩＤＡ肝胆显像，其中１５例行Ｂ超检查。７例经阑尾间置胆道术后１～３个月行９９ｍＴｃＥＨＩＤＡ显像复查。胆管囊肿典型影像特征为类圆形或椭圆形放射性浓聚。９９ｍＴｃＥＨＩＤＡ显像对胆管囊肿的诊断符合率为８８９％（１６／１８）。７例术后复查，证实胆道排泄通畅。９９ｍＴｃＥＨＩＤＡ显像对胆管囊肿诊断具有较高的灵敏性及准确性，尤其对术后重建胆道功能的评价具有明显优势。更多还原

【Abstract】 PURPOSE To assess the value of 99m Tc EHIDA scintigraphy in diagnosis and follow up after surgery in pediatric patients with biliary cyst METHODS 99m Tc EHIDA scintigraphy were performed on 18 children who were clinically suspected with biliary cysts and repeat scintigraphy after surgery were given to 7 of them Among these 18 cases, 15 received ultrasonic examinations Final diagnosis in all cases were proved by surgery and pathology RESULTS The classical feature of biliary cysts in scintigraphy appeared as abnormal circular or ellipsoid “hot” areas The diagnostic coincidence rate were 88 9% (16/18) Repeated postoperative scintigraphy showed that biliary excretion became normal compared to preoperation CONCLUSIONS 99m Tc EHIDA scintigraphy may be a sensitive and accurate method in diagnosis of biliary cyst in children It may showed its advantage especially in evaluation of biliary functional change after operation更多还原
