Two Cases of Aspiration Pneumonia after Endoscopic Submucosal Dissection / 대한소화기내시경학회지

ABSTRACT

The greatest advantage of endoscopic submucosal dissection (ESD) in the stomach is that it can be used to perform en bloc resection of a large gastric neoplasm. However, ESD is more technically difficult and more commonly associated with prolonged procedure time and complications than conventional endoscopic mucosal resection. Until now, only a few reports have considered aspiration pneumonia after ESD, which is rare, but can be fatal. We experienced two cases of aspiration pneumonia after ESD with a gastric neoplasm. One was treated by intensive care with mechanical ventilation, and the other by antibiotics only. Prevention is thought to be important for aspiration pneumonia after ESD; therefore, patients at high risk for aspiration pneumonia are urged to take precautions. We considered various factors contributing to aspiration under endoscopy, such as local pharyngeal anesthesia, procedural time, and bleeding.
