- Abstract
<bold>Background: </bold>Sonographic assessment before congenital diaphragmatic hernia repair has rarely been studied.<bold>Objective: </bold>To evaluate the accuracy of preoperative ultrasound in measuring the defect size and in anticipating the presence of a rim and thereby to determine ultrasound's usefulness in informing the surgical approach for definitive repair of congenital diaphragmatic hernia.<bold>Materials and Methods: </bold>We performed a retrospective review of the medical records of seven children with left congenital diaphragmatic hernia who had undergone ultrasound and definitive repair between 2014 and 2017 at our institution.<bold>Results: </bold>The estimated defect size by ultrasound to the actual defect size measured intraoperatively for each case were as follows: 23 × 25 mm to 20 × 26 mm (case 1); 23 × 30 mm to 20 × 30 mm (case 2); 43 × 25 mm to 30 × 30 mm (case 3); 21 × 23 mm to 20 × 25 mm (case 4); 19 × 24 mm to 10 × 30 mm (case 5); 32 × 33 mm to 30 × 50 mm (case 6); and almost total absence to 40 × 50 mm (case 7). Presence or absence of each part of the diaphragm rim evaluated by ultrasound was almost identical with the actual intraoperative findings. According to the ultrasound findings, we performed a successful thoracoscopic repair in cases 1-5 with relatively small defects and presence of all parts of the rim or absence of only posterolateral rim.<bold>Conclusion: </bold>There was good concordance between ultrasound findings and operative findings regarding the size of the defect and presence or absence of the diaphragm rim.
