The most common cause of regurgitation is reflux of acid from the stomach into the oesophagus while the patient is under anaesthesia.
Acidic fluid can provoke oesophagitis. This results in poor motility of the oesophagus, therefore water and food will accumulate in this structure.
In most cases, oesophagitis is self-eliminating and will resolve within two or three days.
Symptomatic treatment of oesophagitis includes feeding bland food, and administering sucralfate and antacids, for example ranitidine or omeprazole.
