Abstract

Purpose

Clinical outcomes in infants with congenital diaphragmatic hernia (CDH) may be improved by thoracoscopic repair. However, the limited domain and large diaphragmatic defects in neonates are obstacles. Here, we present a special knot-tying technique that facilitates a safe and efficient thoracoscopic CDH repair in neonates.

Methods

An extracorporeal slip knot is assembled after a stitch through the diaphragmatic edge, one end of the string is pulled, and the knot slides to reach the diaphragm easily without a knot-pusher. Then two more uncomplicated single-loop knots are performed to secure its tightness intrathoracically. Twenty-six consecutive neonates with CDH were treated by this technique. The technical advantages and clinical outcomes were evaluated.

Results

All 26 patients were treated successfully, including 6 patch-repairs and 1 case with associated extra-lobar pulmonary sequestration. The mean operative times with and without patch-repair were 149 ± 26 min and 95 ± 25 min, respectively. All cases were completed without conversion. No recurrence was observed at a median follow-up of 13.7 months (range 5.8–29.8 months).

Conclusions

This special knot-tying technique is easy to learn and does not require any additional devices. It is a simple and accessible technique that can facilitate thoracoscopic repair of neonatal CDH within the limited space and with patch-repair.
