Kim, Lee, Chung, Lee, Shin, and Choi: Severe respiratory depression precipitated by unrecognized gastric perforation during endoscopic submucosal dissection under deep sedation - A case report -

摘要

Endoscopic submucosal dissection (ESD) is widely performed these days as the standard procedure for the treatment of early gastric cancer. During ESD, insertion and rotation of the scope, air insufflation, incision and hemostasis may provoke pain, which commonly requires either general anesthesia or moderate to deep sedation. Deep sedation precludes the need for general anesthesia, and can help endoscopists speed up the procedure compared to light sedation. But, there are risks of respiratory complication. We report a case of respiratory compromise caused by pneumoperitoneum from unrecognized gastric perforation during ESD under deep sedation.
