A floppy baby with elevated right hemidiaphragm and large stomach bubble on chest radiograph: what’s the diagnosis?

A preterm neonate of 36 weeks’ gestation was born via emergency lower segment caesarean section, requiring respiratory support soon after birth. She was hypotonic from birth and was found to have a large gastric bubble and a raised right hemidiaphragm on X-ray. She reached full feeds through a nasogastric tube on day 3 of life but later developed severe gastro-oesophageal reflux with pulmonary aspiration. What is the likely diagnosis?
