Abstract

Objective:To assess the accuracy of transabdominal sonography (TAS) and transvaginal sonography (TVS) in the diagnosis of ectopic pregnancy by meta-analysis.Methods:Literatures about transabdominal sonography (TAS) versus transvaginal sonography (TVS) in patients with ectopic pregnancy issued from January 1995 to December 2008 were retrieved and the effects were quantitatively estimated with fixed-effect model and random-effect model by meta-analysis.Results:In 22 trials,the diagnose accordance rate between TVS and TAS is significant,with the pooled RR 1.37 (95% CI 1.24～1.52).Conclusions:TVS was better in the diagnosis of ectopic pregnancy than TAS.
