Pneumomediastinum as a complication of upper gastrointestinal endoscopy.
Secondary or complex pneumomediastinum following esophagoscopy is due to an esophageal perforation. Primary or simple pneumomediastinum may be caused by maneuvers such as coughing, gagging, swallowing, choking, and valsalva. These maneuvers are common during upper gastrointestinal endoscopy. Esophageal perforation is a potentially life threatening event, while simple pneumomediastinum is usually a benign self-limited disorder. Although the presentation may be similar, different morbidities compel prompt evaluation for distinction between these two entities and appropriate management. We present a case of pneumomediastinum that developed immediately following upper gastrointestinal endoscopy. Implications of diagnosis, management, and prognosis are discussed.
