Transient parotid gland swelling could happen as complication after per oral endoscopy or
intubation. We reported a 53-year-old man who developed transient unilateral parotid gland
swelling following esophagogastroduodenoscopy (OGDS) with dilatation of achalasia cardia.
The swelling of the parotid gland was transient and resolved completely without any
intervention.
