【摘要】目的：研究饮清水对健康体检者胆囊超声检查的影响。方法：随机选择320例2019年1月至2019年4月在我机构进行健康体检者，分为饮水100ml组和饮水200ml组，每组160人，测量其空腹和分别饮水100ml和200ml后不同时间的胆囊容积，对比不同饮水量后胆囊容积与空腹胆囊容积相比有无显著变化。结果：饮水100ml后各时间胆囊容积与空腹胆囊容积相比无显著性差异，饮水200ml后各时间胆囊容积与空腹胆囊容积相比有显著性差异。结论：饮少量清水（≤100ml）对健康体检者胆囊的超声检查无显著影响。

【Abstract】Objective To Study influence of drinking water on ultrasonic examination of gallbladder for people receiving health check-up. Methods After random selection of 320 people who received health check-up in our institution from January 2019 to April 2019. It was divided into group of drinking 100ml water and group of drinking 200ml water， each group composed of 160 people， the gallbladder volumes were measured on an empty stomach and at different times after drinking water of 100ml and 200ml respectively， the  gallbladder volumes after drinking different volumes of water were compared to the gallbladder volumes on an empty stomach. Results There is no significant difference between  gallbladder volumes on en empty stomach and gallbladder volumes at different times after drink 100ml of water. There is significant difference between gallbladder volumes on en empty stomach and gallbladder volumes at different times after drink 200ml of water. Conclusion Drinking small amounts of water（≤100ml）has no significant influence on ultrasonic examination of gallbladder for people receiving health check-up.

健康體检者体检前都被要求禁食水6小时，禁饮水的原因是饮水可能对胆囊的超声检查产生影响，但是饮水究竟会对胆囊产生何种影响，笔者查阅中外文献未能查到相关资料。体检过程中有些体检者口渴难耐，但被告知严禁饮水，笔者及很多同事对此抱有疑问。饮少量水会对胆囊产生显著影响吗？胆囊容积的变化是观察胆囊有无改变的一个良好指标。基于循证医学的原则，笔者及同事自2019年1月至4月，对320例健康体检者饮水前后胆囊容积进行了测量，报告如下。

1.对象

随机选取2019年1月至4月参加我诊所健康体检的320名体检人员作为研究对象，其中男性235例，女性85例，年龄18-77岁，平均年龄（38.3±9.5）岁。随机分为两组，其中160例纳入饮水100ml组，此组中男性117例，女性43例，年龄20-67岁，平均年龄（38.4±9.8）岁。另外160例纳入饮水200ml组，此组中男性118例，女性42例，年龄18-77岁，平均年龄（38.2±9.1）岁。……
