内镜下乳头球囊扩张术在胆总管结石治疗中的应用

内镜下乳头括约肌切开术(EST)在胆总管结石治疗中已被广泛应用,但内镜下乳头球囊扩张术(EPBD)作为一种标准治疗方法仍不能为广大胆管内镜医师所公认。EPBD与EST相比主要的优点在于可以保留十二指肠乳头的功能。但是对于直径较大的结石,由于胆管开口相对较小,EPBD常需反复的机械碎石,另外EPBD术后胰腺炎发生率较EST高。现对EPBD在胆总管结石治疗中的价值进行综述。

Application of Endoscopic Papillary Balloon Dilation for Treatment of Common Bile Duct Stones
