A 51-year-old female diagnosed to have compensated chronic liver disease underwent endoscopy to assess variceal status. Endoscopy was unremarkable and uneventful. Thirty minutes postprocedure, she developed painless bilateral swelling over the parotid regions [Figure 1]. On palpation, there were no warmth, tenderness, crepitus, or signs of subcutaneous emphysema over the neck and chest. Bilateral parotid enlargement was confirmed by ultrasound. The patient was managed conservatively. She was allowed liquids 3 h after the procedure. The swelling spontaneously decreased in size by almost 30% after 2 h. The next morning, the patient was comfortable with complete regression of the swelling. Postendoscopy parotid enlargement is a transient complication that usually subsides within 24 h. The mechanisms postulated for postendoscopy transient parotitis are blockage of the salivary ducts by secretions, venous congestion caused by straining or coughing during the procedure,[1] the use of anticholinergic drugs or neuromuscular blockers, and reflex parasympathetic stimulation during the procedure leading to vasodilation in the parotid gland.[2] Head manipulations and prolonged duration of endoscopy are considered risk factors for the condition.[3] If the swelling does not resolve rapidly, further evaluation is suggested.{Figure 1}
