Congenital Diaphragmatic Hernia: Experience and Results of Thoracoscopic Repair from a Tertiary Care Hospital

Abstract

Introduction Congenital diaphragmatic hernia (CDH) is one of the most common congenital anomalies encountered by pediatric surgeons. With the advances in the pediatric minimal access surgery, its role in the repair of CDH has also increased. We have been using thoracoscopy for the repair for CDH since 2015. We herein report our experience of CDH repair in newborns. Materials and Methods A retrospective review was conducted from July 2015 to December 2019 in the Department of Pediatric surgery after ethical approval from the institutional review board and included all the children with CDH who underwent thoracoscopic repair. The case records were used to assess the demographic details, type of defect, and early and late postoperative complications of thoracoscopy in CDH. Results Thoracoscopic repair was attempted in 29 patients of CDH. Eight (27.5%) patients converted to open procedure and were excluded from the study. Primary closure of the diaphragmatic defect was performed in 90.4% (19) patients. Also, 9.5% (2) children required mesh repair. There was no intraoperative death. Postoperative ventilation was required in 57.1% (12) children. The mean time on the ventilator was 3.03 ± 0.9 days. The mean age of children requiring postoperative ventilation was less compared with children who were extubated in the postoperative period (p = 0.032). The median follow-up in our study was 12 months and 28.5% of patients developed recurrence of the diaphragmatic hernia. All the children underwent laparotomy and repair of the diaphragmatic defect. Conclusion Thoracoscopic repair is a safe and effective option for the repair of CDH in children performed by surgeons with significant procedure experience.
