摘要 目的探讨内镜下乳头括约肌球囊扩张术(EPBD)在胆囊切除术后综合征(PCs)胆总管末端良性狭窄中的临床应用价值。方法选择诊断为PCS胆总管末端良性狭窄的患者84例,均行EPBD治疗,观察疗效和不良反应。结果84例中82例(97.6%)成功实施EPBD,2例(2.4%)未成功者为乳头冗长变形无法实施经内镜逆行胰胆管造影术。胆总管末端微小结石26例(31.O%),乳头炎性狭窄28例(33.3%),乳头旁憩室12例(14:3%),肝胰壶腹括约肌运动障碍(SOD)14例(16.7%),先天性小乳头4例(4.8%)。术后第1周:腹部症状消失74例,减轻4例(乳头旁憩室),无变化4例(SOD);磁共振胆胰管成像(MRCP)示胆总管内径恢复正常70例,减轻12例。术后第4周:腹部症状消失78例,减轻4例(SOD);MRCP示胆总管内径恢复正常76例,减轻6例。EPBD治疗后发生并发症6例(7.1%,6/84),其中轻症急性胰腺炎4例,乳头部出血2例,均经保守治疗痊愈。结论胆总管末端良性狭窄是PCS的常见病因,EPBD不但能进一步明确PCS的病因,而且能有效治疗PCS胆总管末端良性狭窄,该方法简便易行,安全可靠。
