Endoscopic sphincterotomy (ES) for common bile duct calculi (CBDC) was performed on 210 patients, and 190 of these were available for follow-up. One hundred seventy-three patients (91%) were successfully treated with ES alone, whereas 17 patients required operation. Stone size was of importance to attain complete clearance of CBDC as larger stones (greater than 1 cm) were significantly more difficult to extract endoscopically than smaller stones (p less than 0.01). A comparison between patients with one CBDC and those with two or more show a statistically significant difference in that the former group is easier to treat successfully (p less than 0.001).
对210例胆总管结石（CBDC）患者实施了内镜下括约肌切开术（ES），其中190例可进行随访。173例患者（91%）仅通过ES就成功治愈，而17例患者需要进行手术。结石大小对于实现CBDC的完全清除很重要，因为较大的结石（大于1厘米）在内镜下取出明显比小结石更困难（p<0.01）。单发性CBDC患者与多发性CBDC患者之间的比较显示出统计学上的显著差异，即前一组更容易成功治疗（p<0.001）。
