Diameters of the common bile duct (CBD) and common hepatic duct (CHD) were measured before and after endoscopic sphincterotomy (EPT) in 100 patients. There was a significant reduction of the lumen diameter in both the CBD and CHD (p less than 0.01) after EPT. A comparison between 32 patients without symptoms (such as pain, residual stones, and elevated levels of liver enzymes) and 19 patients with remaining symptoms after EPT, showed a statistically significant reduction in both CBD and CHD diameters (p less than 0.001) in the former group, and no statistically proven changes in the diameters in the latter group, since a change of less than 1.5 mm was not considered significant. Therefore, the absence of a reduction or a dilatation of the diameter of the CBD after EPT may suggest that these patients may have persisting complaints after EPT. Measurements on models (phantoms) show that body position of the patient during endoscopic retrograde cholangiopancreatography (ERCP) has little and negligible influence on the measured diameters of the CBD and CHD.
对100例患者在内镜括约肌切开术（EPT）前后测量胆总管（CBD）和肝总管（CHD）的直径。EPT后，CBD和CHD的管腔直径均显著减小（p<0.01）。对32例无症状（如疼痛、残余结石和肝酶水平升高）的患者与19例EPT后仍有症状的患者进行比较，结果显示，前一组患者的CBD和CHD直径均有统计学意义的减小（p<0.001），而后一组患者的直径无统计学证实的变化，因为直径变化小于1.5mm不被认为具有显著性。因此，EPT后CBD直径未减小或扩张可能表明这些患者在EPT后可能仍有持续的不适。对模型（模拟物）的测量表明，患者在内镜逆行胰胆管造影（ERCP）期间的体位对所测量的CBD和CHD直径影响很小且可忽略不计。
