We evaluated gallbladder contractility in 58 colicky infants and 57 age-matched controls. Gallbladder size was measured before and 1 h after feeding and the contraction index of the gallbladder was calculated. The results showed decreased contractility of the gallbladder in colicky infants: mean contraction index in colicky infants was 56% (95% confidence interval, 49-63%) and in controls 67% (61-73%). No difference was found in the fasting size of the gallbladder. Postprandial contraction was decreased in colicky infants examined in the evening (n = 14) compared with those examined in the morning (n = 44). Decreased contraction of the gallbladder was found in those colicky infants who presented colicky cry compared with colicky infants without symptoms at the time of examination. No structural abnormalities were found in the general abdominal survey. In conclusion, infants with colic have hypocontractility of the gallbladder. This indicates abnormal biliary tract physiology in association with infantile colic.
我们评估了58名患腹绞痛婴儿和57名年龄匹配的对照者的胆囊收缩功能。在喂食前和喂食后1小时测量胆囊大小，并计算胆囊收缩指数。结果显示，患腹绞痛婴儿的胆囊收缩功能下降：患腹绞痛婴儿的平均收缩指数为56%（95%置信区间，49 - 63%），而对照者为67%（61 - 73%）。空腹时胆囊大小未发现差异。与上午检查的患腹绞痛婴儿（n = 44）相比，晚上检查的患腹绞痛婴儿（n = 14）餐后收缩功能下降。与检查时无症状的患腹绞痛婴儿相比，出现腹绞痛哭闹的患腹绞痛婴儿胆囊收缩功能下降。在一般腹部检查中未发现结构异常。总之，患腹绞痛的婴儿胆囊收缩功能减退。这表明与婴儿腹绞痛相关的胆道生理异常。
