【摘要】：目的:探讨口服胃窗超声造影剂对胆总管下段梗阻性病变的超声诊断价值。方法:对临床诊断为胆总管下段梗阻性病变的52例患者,腹部常规超声检查后,进行口服胃窗超声造影剂法检查,结果与手术或其他影像学检查对照。结果:常规超声检查有23例因腹腔胃肠道内气体干扰图像显示不清,无法做出诊断。口服胃窗超声造影剂法检查可较好地显示胆总管梗阻的部位和病变征象,除1例为临床少见的胆总管蛔虫诊断不准确外,其余均诊断准确。常规超声加口服胃窗超声造影剂检查,准确率为98.1%(51/52)。常规超声与口服胃窗超声造影剂法对胆总管梗阻部位和病变显示率差异有统计学意义(P0.05)。结论:使用胃超声造影剂检查可以减少对超声检查人员超声检查技术手法的依赖,大大提高胆总管下段的显现能力和对病变的诊断鉴别诊断能力,为临床腔镜术前手术方案的评估和选择提供简便、经济、准确的依据,适合在基层医院推广应用。
[Abstract]:Objective: to evaluate the value of oral gastric window ultrasound contrast medium in diagnosis of common bile duct obstruction. Methods: 52 patients with lower common bile duct obstruction were examined with oral gastric window ultrasound contrast medium after routine abdominal ultrasonography. The results were compared with those of surgery or other imaging examinations. Results: 23 cases were unable to make diagnosis because of gas interference images in abdominal cavity. The location and pathological signs of common bile duct obstruction could be well demonstrated by oral gastric window ultrasound contrast medium examination. Except for one case which was a rare clinical diagnosis of common bile duct ascariasis, the others were all accurate. Conventional ultrasound combined with oral gastric window ultrasound showed an accuracy of 98.1% (51 / 52). Conventional ultrasound and oral gastric window ultrasound contrast method for common bile duct obstruction and lesions showed significant difference (P0.05). Conclusion: the use of gastric ultrasound contrast agent can reduce the dependence on ultrasonic examination technique and improve the ability of displaying the lower part of the common bile duct and differential diagnosis of the lesions. It provides a simple, economical and accurate basis for the evaluation and selection of clinical endoscopic preoperative surgery, and is suitable for popularizing and applying in primary hospitals.
