To assess the sensitivity and specificity of ultrasonography in differentiating causes of acute right lower quadrant pain in women of child-bearing age by taking surgical outcome as the gold standard.
The descriptive analytical study was conducted at PNS Shifa Hospital, Karachi, from July to December 2008, and comprised female patients of child-bearing age who presented with acute right lower quadrant pain and underwent surgery after ultrasonography. SPSS 10 was used for statistical analysis.
Of the 75 patients, 54(72%) patients were symptomatically and sonographically positive to have either acutely inflamed non-compressible appendix or focal fluid collection in right lower quadrant with normal pelvic viscera. Sensitivity of 94% and specificity of 84% were calculated.
Ultrasound had a sensitivity and specificity justifying its usage as a good diagnostic tool in emergency situations to avoid undue surgical interventions.
以手术结果作为金标准，评估超声检查在鉴别育龄期女性急性右下腹疼痛病因方面的敏感性和特异性。
2008年7月至12月在卡拉奇的PNS Shifa医院进行描述性分析研究，纳入出现急性右下腹疼痛且在超声检查后接受手术的育龄期女性患者。使用SPSS 10进行统计分析。
75例患者中，54例（72%）在症状和超声检查方面显示为急性炎症性不可压缩阑尾或右下腹有局灶性液性聚集且盆腔脏器正常。计算得出敏感性为94%，特异性为84%。
超声的敏感性和特异性证明其可作为紧急情况下避免不必要手术干预的良好诊断工具。
