Dilatation of unobstructed extrahepatic bile ducts was observed in patients with conditions associated with intestinal hypomotility. For further investigation of this association, a prospective study was undertaken in which the common hepatic duct was measured in 15 patients before and 1 day after laparotomy, when all patients had postoperative paralytic ileus. A statistically significant (p less than 0.01) increase in the mean diameter of the hepatic duct was observed postoperatively. When compared with the preoperative measurement, the mean diameter of the duct almost doubled, from 3.3 to 5.9 mm. This phenomenon may be due to persistent contraction of the sphincter of Oddi that occurs when intestinal hypomotility eliminates the stimuli for cholecystokinin release.
在患有肠道动力不足相关病症的患者中，观察到无梗阻性肝外胆管扩张。为进一步研究这种关联，进行了一项前瞻性研究，对15例患者在剖腹手术前及术后1天测量肝总管，此时所有患者均有术后麻痹性肠梗阻。术后观察到肝总管平均直径有统计学意义的增加（p小于0.01）。与术前测量值相比，胆管平均直径几乎翻倍，从3.3毫米增至5.9毫米。这种现象可能是由于肠道动力不足消除了胆囊收缩素释放的刺激时，奥迪括约肌持续收缩所致。
