Background: Diaphragmatic plication is the most widely used surgical approach for treating congenital diaphragmatic eventration (CDE) in children. This study aims to assess current surgical practice for this pathology in children. Methods: Retrospective data analysis of a multicentric cohort of pediatric patients operated on for CDE between 2010 and 2021. Comparative description of the different surgical approaches and their outcomes, including robot-assisted thoracoscopic surgery (RATS). (Clinical TrialsNCT04862494). Results: 112 patients, aged 12 [5 - 21] months, were operated on for CDE. Diaphragmatic plication was performed using thoracoscopy or RATS in 69 (62%) cases, postero-lateral thoracotomy (PLT) in 15 (13%), and using an abdominal approach in 28 (25%). Relief of symptoms and improvement in the diaphragmatic level on chest radiographs were obtained in 88% and 90% of the cases, respectively. We recorded 32 peri- or early postoperative complications (29%) and eight recurrences of eventration (7%), but found no correlation between these complications and the surgical approach used. Compared to other approaches, PLT multiplied the duration of intravenous analgesia by three (96 vs 36h, p<0.0001), and the length of hospital stay by two (8 vs 4d, p = 0.002). Compared to thoracoscopy, RATS provided more perioperative hepatic injuries and equivalent short-term results, but all five patients remained symptomatic and two of them experienced chest wall deformities in long-term follow-up. Conclusions: Diaphragmatic plication via a minimally invasive thoracic approach may be the best treatment option for cases of symptomatic CDE. RATS emerges as a promising surgical approach, but further is required to confirm that it is, at least, not inferior to thoracoscopy.
