Uvular necrosis after upper endoscopy: a case report and review of the literature.
Uvular necrosis after endotracheal intubation or upper endoscopy is rare. We report here on a case of uvular necrosis and ulceration after endoscopy. The combination of ulceration and necrosis suggests uvular ischemia during endoscopy. The uvula may have been sandwiched between the shaft of the endoscope and the gum or hard palate, or may have been pressed against the posterior pharynx, leading to prolonged ischemia and resultant ulceration and necrosis. Uvular trauma can also be caused by oral pharyngeal suction. We recommend that post-endoscopy uvular necrosis should be managed conservatively based on the patient's symptoms. In all reported cases, and in the present case as well, the uvula healed and the symptoms resolved within 2 weeks (5 - 14 days) after the procedure. The uvula regained its normal appearance. Overall, these patients should have a good clinical outcome.
