目的 :探讨飞行人员B型超声特点。方法 :对来院疗养的 4 46名飞行人员进行肝、胆、脾、肾等脏器B型超声检查。结果 :共检出异常病例 1 86例 ,阳性率为 4 1 7% ,其中 1 6 2例 (87 1 % )B超异常但无自觉症状。病种中以脂肪肝最为多见 (4 8 9% ) ,其次是肝、胆、肾脏结石 (1 7 7% )、肝、肾囊肿 (1 0 7% )和胆囊息肉样病变 (7 0 % )。阳性率随年龄增加而上升 (P <0 0 1 ) ,运输机飞行人员检出率最高 (4 7 3% ) ,其次是轰炸机飞行人员 (39 8% )。结论 :B型超声检查对早期发现飞行人员腹部疾病具有诊断价值
Objective: To explore the characteristics of B-mode ultrasound of pilots. Methods: 4 46 pilots coming to hospital for treatment of liver, gallbladder, spleen, kidney and other organs type B ultrasound. RESULTS: A total of 1 86 cases were detected abnormally, with a positive rate of 41.7%. Among them, 162 (87.1%) had abnormal B-ultrasound but no symptoms. Fatty liver was the most common type of disease (489%), followed by liver, gallbladder and kidney stones (17.7%), liver and renal cyst (17%) and gallbladder polypoid lesion (70% ). The positive rate increased with age (P <0.01). The highest detection rate was found in transport aircraft pilots (47.3%), followed by bomber pilots (39.8%). Conclusion: B-mode ultrasonography has diagnostic value for the early detection of abdominal diseases in pilots
