| 目的 提高肝外胆管梗阻性病变的超声显示率。方法 对肝外梗阻性黄疸而常规超声检查未显示出梗阻病变的77例患者实施生理盐水保留灌肠使结肠充盈成为肝外胆管的透声窗,然后采用腹部超声诊断仪寻找其后方的胆管梗阻病变。结果 灌肠成功的患者71例(灌肠成功率92.0%),能显示肝外胆管梗阻病变68例,显示率为96.0%。其中结石55例,肿瘤11例,炎性狭窄2例。仍有3例未能显示出肝外胆管梗阻病变。结论 被生理盐水充盈的结肠确能作为肝外胆管的透声窗,从而使肝外胆管梗阻病变的超声显示率显著提高。 |

| Objective To improve the detection rate of extrahepatic bile duct obstructive diseases by ultrasonography. Methods Seventy-seven patients were examined employing normal saline retention enema, in which the colon was filled with normal saline to make it as an acoustic window for extrahepatic bile duct, and then ultrasonic examination was performed to visualize the lesions behind the colon. Results Seventy-one patients (92.0%) were successfully examined by the retention enema method, and extrahepatic bile duct obstructive lesions were visualized in 68 patients with the sensitivity of 96%. Among them, 55 patients were with stones, 11 with tumors, and 2 with inflammatory stenosis. Three of 68 patients had not shown any obstructive pathological lesions. Conclusion The water-filled colon can be used as the acoustic window of extrahepatic bile duct, which makes the ultrasonic diagnosis much more sensitive to the extrahepatic bile duct obstruction. |
