Abstract
The efficacy and safety of endoscopic submucosal dissection (ESD) for treating cervical esophageal carcinoma (CEC) are well recognized [1] [2]. However, performing ESD in the cervical esophagus remains challenging due to upper sphincter contraction and endotracheal intubation balloon compression. Herein, a deeper endotracheal intubation was applied to tackle this technical difficulty.
