【摘要】 本文应用电视X线录象术对胆道运动进行动态观察。排胆动作表现为胆总管末端括约肌呈周期性、节律性的舒缩活动,排胆频率为4～8次/分,十二指肠往返蠕动以4～10次/分的频率进行,和括约肌舒缩活动以同步最常见。胆总管充满结石,壶腹嵌顿结石时,排胆动作减弱或消失。壶腹部肿瘤时排胆动作消失且胆总管末端呈僵硬状态。胆总管肠道吻合术后原来排胆频率依然存在。括约肌成形术呈完全性者,注射吗啡后无反应,十二指肠逆蠕动时肠内容物可倒入胆总管,不完全性者功能仍存在,注射吗啡后起痉挛作用。更多还原

【Abstract】 Cineradiography was used for depiction of bile propulsion into the duodenum through the rhythmic and cyclic contraction-relaxin activity of the distal sphincter of the common bile duct.The rhythmic contractions were seen to occur at a frequency of 4-8 times per minute synergizing with duodenal peristalses which occurred 4-10 times a minute.The frequency of intermittent bile discharge decreased or ceased when gallstones filled the common bile duct or when there was impaction of gallstones in the ampulla of Vater. If the latter was occupied by a tumor, the duct appeared stiffened, and activity ceased. After sphincteroplasty, intestinal content reflux into the common bile duct was seen, with partial resection, contractile activity may still be seen after injection of morphine. But, after complete sphincterectomy, not only is there still duodenal reflux, but there is also lack of response to injection of morphine.更多还原
