To evaluate factors related to conversion to open repair (OR) during thoracoscopic repair (TR) in congenital diaphragmatic hernia (CDH).


CDH subjects who were diagnosed prenatally or within 6 h of birth and underwent TR at our institution from 2007 to 2015 were reviewed. Two groups were defined: Group A, subjects who tolerated TR; and Group B, subjects who required conversion to OR.


Twenty-nine subjects (Group A, 20; Group B, 9) underwent TR. Patients’ demographics were not significantly different between the two groups. In Group A, pre-operative arterial blood gas analysis showed mean PaCO2 37.4 mmHg, mean pH 7.45, and mean PaO2 201.6 mmHg, which were not significantly different from those of Group B (PaCO2 40.6 mmHg, pH 7.43, and PaO2 251.1 mmHg). Two Group B cases required conversion due to cardiopulmonary instability. The remaining seven cases were converted for technical reasons (large defect in two, anterior location of the defect in two, bleeding from short gastric vessels or spleen in two, and insufficient operative view in one).


TR can be performed safely in selected cases of CDH. CDH with a large defect and/or an unusual location of the defect remains a challenge for pediatric surgeons.
