Acute bilateral parotid gland enlargement

Bilateral parotid swelling after upper gastrointestinal procedures is a very rare occurrence. It is a self limiting transient event following anaesthesia [1], oesophagoduodenoscopy, and bronchoscopy [2]. The cause for this condition is not known due to rarity of the condition. The possible causes are retention of secretions causing blockage of the parotid ducts, dehydration, parasympathetic stimulation during oesophageal intubation, venous congestion due to excessive coughing and straining during procedure. Knowledge of this event and the self limiting nature of the problem is important for the treating physician. We report two cases where bilateral parotid swelling following upper gastrointestinal endoscopy.
