目的：探讨术前超声检查在医院船筛选外科手术患者中的应用价值。方法应用彩色多普勒超声诊断仪的腹部和高频探头，对来自医院船主平台和前出到访国巡诊的患者2568例，分别对腹部的胆囊、子宫附件或浅表肿块进行检查，筛选出230例超声声像图表现为良性肿块并进行手术的患者，将超声诊断结果与病理结果进行对照，对比超声诊断符合率。结果230例手术患者中声像图表现为胆囊结石3例，子宫肌瘤2例，附件肿块1例，浅表肿块224例，又分17种病变。手术标本病理证实230均为良性病变，超声诊断符合率100%。结论在医院船执行海外医疗活动中，将术前超声作为肿瘤病人术前筛选的常规检查，其诊断符合率高，将其列为术前风险评估的常规检查手段，可有效降低手术风险，为外事医疗活动的成功进行提供有力技术保障。“,”Objective To explore the value of ultrasound screening on the patient’s pre-operation condition on the hospital ship. Methods A total of 2,568 outpatients of the countries where the ship visited were screened with the abdominal and high frequency probe of the color Doppler ultrasonic diagnostic apparatus exam for abdomen gallbladder, uterine accessory or superficial masses. 230 of them were diagnosed as benign masses, and were selected for operation. The results of their ultrasound examination were compared with the pathological findings to find the coincidence rate. Results Of the 230 patients according to the ultrasound, there were 3 cases of cholecystolithiasis, 2 cases of uterine fibroids, 1 case of adnexal mass and 224 cases of superficial mass, and the results were divided into 17 kinds of diseases. All of the specimens were confirmed as benign masses pathologically which were consistent with the ultrasonography, and the coincidence rate was 100%. Conclusion During the hospital ship’s overseas mission, the ultrasonography is considered as being important in preoperative screening the benign tumor for its high accuracy, and it is highly recommended to be used as an routine examination method for preoperative risk assessment, which may effectively reduce the operation risk and provide strong technical support for the success of the mission.
