Review Meta Analysis
Meta-analysis of sonography in the diagnosis of inguinal hernias.
Groin hernias are common conditions, and there is a need for accurate imaging when the clinical diagnosis is not clear. A meta-analysis was undertaken to investigate the diagnostic accuracy of sonography in the diagnosis of inguinal hernias. After review of literature searches, 9 original articles were included. ⋯ In cases of diagnostic uncertainty, sonography offers value as an initial imaging modality. It has advantages over other radiologic methods, as it is inexpensive and has minimal complications. When the clinical diagnosis of an inguinal hernia is uncertain, sonographic findings should be interpreted in conjunction with clinical judgment, as its diagnostic accuracy is reduced in the absence of any clinically palpable hernia.
