The port-less technique (PLT) means only one or two ports are used; in most cases only the telescope would require a port. At our center, the VATS services were started in 2008, initially using the standard three-ports technique but shortly after this was replaced with PLT for all neonatal and pediatric VATS. The rationale of doing PLT was so that working instruments could move easier in the pediatric thoracic cavity. Furthermore, budget constraints did not allow us to purchase trocars of different sizes. Patients and methods: A review of all PLT cases was carried out at our institution from January 2008 to September 2018. We documented the diagnosis and type of surgery performed, age at surgery, number of ports used, conversion rate, morbidity and mortality as well as gross chest wall growth. Results: A total of 46 PLT cases were carried out; 16 were in neonates (34.7%). Conversion to thoracotomy occurred in five patients (10.8%). Diagnosis ranged from congenital anomalies like esophageal atresia to infective cause like empyema thoracis. Immediate morbidity occurred in four patients (8.7%) and there was one perioperative mortality (2.2%). The majority of PLTs (54%) were using two ports, and another 46% of PLTs were successfully carried out using one port. All neonatal and infant PLT cases were using one port (46%). Maximum follow-up was for 5 years and gross growth of chest wall was good. Conclusion: PLT is a feasible and safe technique for a variety of cases for neonatal and pediatric surgical intrathoracic pathology. We recommend PLT for all neonatal and pediatric VATS.
