Aim: We evaluated a series of late-presenting congenital diaphragmatic hernia (Late-CDH) cases and assessed the reliability and risks of laparoscopic and thoracoscopic approaches for Late-CDH at a single institution. Materials and Methods: From 2005 to 2017, we experienced totally 11 patients with Late-CDH who received endoscopic repairs. We retrospectively surveyed the approach, defect size, operating time, and postoperative outcomes, including recurrence. Results: Eleven patients (Bochdalek, n = 10; Morgagni, n = 1) underwent a total of 14 endoscopic repairs (laparoscopy, n = 10; thoracoscopy, n = 4). The average defect size was ∼3.1 × 1.5 cm. In all 14 endoscopic repairs, patients received intracorporeal interrupted nonabsorbable stitches and extracorporeal knot tying were applied, without the use of an artificial patch. In the laparoscopic repairs, 7 patients received left-handed suturing when closing the diaphragmatic defect, because the reduced viscera lay directly below the posterior rim of the diaphragmatic defect, making it difficult to confirm the rim. In contrast, in the thoracoscopic repairs, the viscera were reduced over the diaphragmatic defect, so the surgeons could easily perform suturing. The average operating time was 172 minutes for laparoscopy and 194 minutes for thoracoscopy. No major intraoperative or postoperative complications occurred in association with either of the approaches. Among the 11 patients, 2 experienced a total of 3 recurrences (all after laparoscopic repairs). Conclusion: Although there were few differences between the laparoscopic and thoracoscopic approaches, because of the technical difficulty of the procedure and the possibility of recurrence with the laparoscopic approach, a thoracoscopic approach may be better for the repair of Late-CDH.
