Background: Endoscopic submucosal dissection has become popular. However, this can cause serious complications. In this case, esophageal perforation caused bilateral tension pneumothorax.
Case: A 60-year-old man with esophageal adenoma underwent endoscopic submucosal dissection under general anesthesia. The peak airway pressure was 25 cmH2O after induction but abruptly increased to 40 cmH2O after 30 min. Respiratory sounds were barely heard. The lack of lung sliding in either (right-dominant) lung on ultrasound. Within minutes, oxygen saturation and systolic blood pressure decreased to 52% and 70 mmHg. Emergent needle thoracostomy, followed by chest tube insertion, was performed on right chest and his vital signs stabilized. Upon transfer to intensive care unit, oxygen saturation and blood pressure decreased again; therefore, a left chest tube was inserted.
Conclusions: Pneumothorax due to esophageal perforation can lead to life-threatening tension pneumothorax. Anesthesiologists should be aware of the risks and emergency treatment. Ultrasound can be useful for immediate bedside patient-care decisions.
