By using ultrasound we were able to observe any increase in the size of human gallbladders during feeding. In 91 of 123 cases (74%), the gallbladder expanded for a short time prior to contraction during feeding. The examination on eight patients after gastrectomy and seven patients after a medically induced vagotomy revealed contraction only in response to feeding. In seven normal adults, 200 ml of air injected rapidly into stomach through a gastric tube was seen to induce gallbladder expansion. These results suggest that the gallbladder expands in response to feeding via a cholinergic vago-vagal reflex.
通过超声检查，我们能够观察到进食期间人体胆囊大小的任何增加。在123例病例中的91例（74%）中，胆囊在进食期间收缩前短时间内扩张。对8例胃切除术后患者和7例药物性迷走神经切断术后患者的检查显示，仅在进食时出现胆囊收缩。在7名正常成年人中，通过胃管将200毫升空气快速注入胃内，可见胆囊扩张。这些结果表明，胆囊通过胆碱能迷走-迷走反射对进食做出扩张反应。
