摘　　要：目的探讨内镜治疗胆总管大结石机械碎石术成功率及结石复发率。方法采用经内镜机械碎石术治疗115例CBD大结石(≥2.0cm),并与同期388例非大结石病例(对照组)对比结石清除率和复发率。结果大结石组88例结石最大径为2.0cm～2.9cm,27例≥3.0cm;对照组150例结石<1.0cm,238例1.0cm～1.9cm。大结石组结石清除率(98.3%)与对照组(99.5%)无显著差异,平均操作例次(2.3次),明显多于对照组(1.4次)。平均随访72.1个月,大结石组结石复发率(16.1%)与对照组(6.1%)有显著差异(P<0.05),平均复发时间分别为18.7个月和24.8个月(P>0.05)。大结石组和对照组结石复发病例中,伴胆囊结石和行胆囊切除者分别占60%和80%,两者无显著差异(P>0.05)。结论EML治疗CBD大结石操作有一定难度,但结石清除率与对照组无显著差异,复发率显著高于对照组,结石>2.0cm复发率高,伴有胆囊结石与既往胆囊切除之间复发率无显著差异。Objective: To investigate the success rate and the relapse rate in the patients with large common bile duct stones treated by endoscopic mechanical lithotripsy (EML). Methods: In our study, we observed 503 patients with CBD stones who underwent endoscopic therapy from January 2000 to December 2002. Among them, 115 patients were in large stones group with CBD stone more than 2 cm and 388 patients were in control group with CBD stone smaller than 2 cm. We compared the clearance rate and the relapse rate of st...
