【摘要】 目的　比较诊断性腹腔灌洗 (DPL)、CT和B超对钝性腹部创伤诊断的准确性。方法　前瞻性分析 61例血流动力学稳定的钝性腹部创伤病例。病人入院后首先行B超和CT检查 ,之后再完成DPL。如 3项检查中有 1项阳性则剖腹探查 ,并将手术发现与检查结果作比较。结果　DPL ,CT ,B超对钝性腹部创伤诊断的敏感性、特异性、准确性分别为 97.4% ,81 .7% ,91 .8% ;97.3 % ,91 .3 % ,95.1 %及 92 .3 % ,90 .9% ,91 .5 %。 3项检查对钝性腹部创伤诊断的准确性相似 ,但B超与DPL和CT相比具有迅速、方便、重复性好、可在床旁进行等优点。结论　在对钝性腹部创伤的诊断中B超可以取代DPL ,CT可作为补充诊断手段更多还原

【Abstract】 Objective To compare the accuracy of diagnostic peritoneal lavage (DPL),abdominal computed tomographic(CT) scanning,and abdominal B ultrasound for the diagnosis of blunt abdominal trauma. Methods Prospective study was made on 61 hemodynamically stable abdominal injury patients.The patients received both CT and B ultrasound before DPL ,A laparotomy was done on the condition that one of the three examinations had positive finding.The surgical findings were compared with that of the diagnostic studies. Results The sensitivity,specificity and accuracy were 97.4%,81.7% and 91.8% for DPL; 97.3% 91.3% ,and 95.1% for CT;and 92.3%,90.9% and 91.8% for B ultrasound.Although the sesitivity,specificity,and accuracy of B ultrasound in the diagnosis of blunt abdominal trauma were similar to DPL and CT, B ultrasound had more advantages than DPL and CT. Conclusions B ultrasound can replace DPL.CT as a supplementary method in the diagnosis of blunt abdominal trauma.更多还原
