Abstract

Purpose

This systematic review focused on reasons for conversions in neonates undergoing thoracoscopic congenital diaphragmatic hernia (CDH) repair.

Methods

Systematic search of Medline/Pubmed and Embase was performed for English, Spanish and Portuguese reports, according to PRISMA guidelines.

Results

Of the 153 articles identified (2003–2023), 28 met the inclusion criteria and offered 698 neonates for analysis. Mean birth weight and gestational age were 3109 g and 38.3 weeks, respectively, and neonates were operated at a mean age of 6.12 days. There were 278 males (61.50%; 278/452) and 174 females (38.50%; 174/452). The reasons for the 137 conversions (19.63%) were: (a) defect size (n = 22), (b) need for patch (n = 21); (c) difficulty in reducing organs (n = 14), (d) ventilation issues (n = 10), (e) bleeding, organ injury, cardiovascular instability (n = 3 each), (f) bowel ischemia and defect position (n = 2 each), hepatopulmonary fusion (n = 1), and (g) reason was not specified for n = 56 neonates (40.8%). The repair was primary in 322 neonates (63.1%; 322/510) and patch was used in 188 neonates (36.86%; 188/510). There were 80 recurrences (12.16%; 80/658) and 14 deaths (2.48%; 14/565). Mean LOS and follow-up were 20.17 days and 19.28 months, respectively.

Conclusions

Neonatal thoracoscopic repair for CDH is associated with conversion in 20% of cases. Based on available data, defect size and patch repairs have been identified as the predominant reasons, followed by technical difficulties to reduce the herniated organs and ventilation related issues. However, data specifically relating to conversion is poorly documented in a high number of reports (40%). Accurate data reporting in future will be important to better estimate and quantify reasons for conversions in neonatal thoracoscopy for CDH.
