Risks of transesophageal endoscopic ultrasonography-guided biliary drainage

Abstract

Summary of Event: Pneumoderma, mediastinal emphysema, and bilateral pneumothorax were developed in the patient who had undergone trans-esophageal endoscopic ultrasonography-guided rendezvous technique. Chest drainage was performed immediately. Teaching Point: Transesophageal approach carries the potential risks of severe complications such as mediastinal emphysema, mediastinitis, and pneumothorax. To prevent puncturing through the esophagus, clipping the esophagogastric junction using a forward-viewing scope before procedure is very useful. In cases of inadvertent transesophageal puncture, devices other than the needle should not be passed through the site.
