This study revealed that even though the addition of NLD intubation does not provide significant benefits beyond probing alone for patients with simple CNLDO, in children with complex CNLDO, NLD intubation should be considered as a primary treatment due to its substantial increase in surgical success rates. Delaying the treatment would increase its success in patients with complex but not the simple CNLDO.
