The esophagus may become perforated during upper gastrointestinal tract endoscopy.
Risk factors for esophageal perforation during endoscopy:
(1) use of a rigid endoscope
(2) difficult intubation
(3) inexperienced endoscopist
(4) uncooperative patient (perhaps indicating inadequate sedation)
(5) elderly frail patients with abnormal anatomy
(6) therapeutic endoscopy (dilatation, etc) or biopsy
(7) presence of a Zenker's diverticulum
Clinical findings:
(1) pain
(2) dyspnea
(3) cyanosis
(4) dysphagia
(5) fever and tachycardia
(6) subcutaneous emphysema
(7) infection

(1) air in the mediastinum
(2) mediastinal widening
