Abstract

Objectives: To compare defect sizes in congenital diaphragmatic hernia (CDH) measured by postnatal ultrasound (US) between neonates who underwent thoracoscopic surgery and neonates who underwent open surgery and between neonates who underwent primary repair and those who underwent patch repair; additionally, to compare the accuracy of US diagnosis with that of surgical diagnosis for the location of the diaphragmatic hernia and the hernial contents. Methods: We included 8 neonates who underwent preoperative US evaluations of CDH. We compared anterior-to-posterior diaphragm defect sizes between thoracoscopic and open surgery approaches and between primary and patch repair by using the Mann-Whitney U test. The diaphragm was divided into 3 segments: anterior, lateral, and posterior. We evaluated the location of the diaphragmatic hernia and the hernial contents. Results: Four neonates who underwent open surgery had larger diaphragmatic hernias than those who underwent thoracoscopic surgery (mean ± SD, 30.5 ± 5.6 versus 16.3 ± 3.3 mm; P =.030). They were also larger in neonates who underwent patch repair than in those who underwent primary repair (33.0 ± 3.0 versus 17.6 ± 4.2 mm; P =.037). Detection of anterior and lateral diaphragm segments was consistent between US and surgical findings. Three of 4 neonates who underwent open surgery and all 3 neonates who underwent patch repair did not show the lateral segment. The hernial contents were also consistent between US and surgical findings. Conclusions: Postnatal US examinations of neonates with CDH could provide surgeons with useful information to determine the surgical approach and repair method. However, since our study cohort was small, further studies are needed with a larger number of neonates with CDH.
