title: Diagnostic value of automated 3D ultrasound for incisional hernia.
abstract: The automated volume scanning system (AVSS) has been applied in breast diseases, but its use in incisional hernias has not been reported. In this study, conventional handheld B-mode ultrasound (HHUS) and AVSS examined a total of 122 hernia defects in 78 patients. The results from two modalities were then compared with surgical findings for the purpose of assessing the diagnostic value of AVSS. Statistics showed that surgeries identified 38 small, 23 medium and 17 large incisional hernias. The results of AVSS completely agreed with surgical findings; however, HHUS misidentified nine large hernias as medium and seven medium hernias as large. AVSS proved to be more accurate than HHUS in measuring the length and width of the hernia. It also outperformed HHUS in both detecting the incisional hernias (91.8% vs. 78.7%, p = 0.00) and determining hernia contents (89.3% vs. 68.0%, p = 0.00). Moreover, the coronal images AVSS obtained clearly displayed the shapes of the hernias, with 46 being regular and 32 irregular. Overall, AVSS can be used as a promising diagnostic modality for incisional hernias.
