An endoscopic manometric technique was used to determine the CBD-duodenum junction pressure profile before and immediately after endoscopic sphincterotomy in 13 patients with common bile duct stones. Premedication (meperidine, atropine, and diazepam) was given to all patients and endoscopic retrograde cholangiopancreatography was performed before endoscopic sphincterotomy. In the patients with intact papilla the features of the sphincter of Oddi motility were similar to those previously described for patients not given premedication or submitted to cholangiography before endoscopic sphincterotomy. Endoscopic sphincterotomy which was successful for immediate stone removal in 9 of 13 patients caused an immediate reduction of sphincter of Oddi motility in all patients, but abolished it in only 2 of them. The present results show that successful common bile duct stone extraction by means of endoscopic sphincterotomy can be accomplished without total abolition of sphincter of Oddi motility.
采用内镜测压技术测定了13例胆总管结石患者在内镜括约肌切开术前及术后即刻的胆总管-十二指肠连接部压力曲线。所有患者均给予术前用药（哌替啶、阿托品和地西泮），并在内镜括约肌切开术前进行内镜逆行胰胆管造影。在乳头完整的患者中，Oddi括约肌运动的特征与之前描述的未给予术前用药或在内镜括约肌切开术前未进行胆管造影的患者相似。13例患者中有9例通过内镜括约肌切开术成功即刻取出结石，这使得所有患者的Oddi括约肌运动立即减弱，但仅2例患者的Oddi括约肌运动消失。目前的结果表明，通过内镜括约肌切开术成功取出胆总管结石并不需要完全消除Oddi括约肌运动。
