患胆囊息肉飞行人员与健康飞行人员的胆囊收缩功能比较

Contrast study of gallbladder emptying between pilots with polypoid lesions of gallbladder and healthy pilots

目的探讨飞行人员胆囊息肉患者组与健康飞行人员(对照组)胆囊排空功能的差异。方法对来院接受年度大体检的18例患有胆囊息肉的飞行人员及18例年龄、飞行机种、飞行时间相仿的健康飞行人员进行胆囊超声检查,分别于空腹状态下及脂餐后1 h测量胆囊最大长径、上下径、前后径,根据椭圆体公式计算空腹胆囊体积及脂餐后残余胆囊体积,计算胆囊排空率。比较两组之间胆囊排空率的差异。结果 PLG组18例,约占同期住院体检飞行人员(257例)的7.0%,总体上PLG组的胆囊排空功能显著低于正常对照组(P<0.05)。结论 PLG是飞行人员中的常见病,其发病可能与胆囊排空功能不良有密切关系。胆囊排空功能检查可以列为招飞体检及飞行员年度体检的常规检查项目。

Objective We planned to analysis the difference of gallbladder contractility between pilots with polypoid lesions of gallbladder r（PLG group） and healthy pilots（Control group）.Methods 18 pilots suffering from PLG and 18 healthy pilots with similar age,flying airplane and flying time were checked gallbladder contractility by colour B-ultrasound.The length（L）,depth（D） and the width（W） of the gallbladder were assessed after overnight fasting and 60 minutes after fat meal separately,the fasting volume（FV） and residual volume（RV） were calculated with the formula： V=（π/6）×L×D×W.The gallbladder ejection fraction（GEF） was calculated with the formula： GEF=（FV-RV）/FV×100%.The fasting-and post fat meal-GEF between the two groups of pilots were compared.Results The pilots with PLG（18 cases） shared 7.0% of all the hospitalized pilots（257cases） for medical examination in the same period.Generally the GEFs at 60 min after fat meal were significantly lower in the PLG group than that in the control group（P0.05）.Conclusion PLG was a common disease in airplane pilots,and its pathologic mechanism might be due to malfunction of gallbladder emptying.Functional examination of gallbladder emptying could be regarded as a routine examination item of recruit pilots and annual flight physical examination.
