Gastric barotrauma induced by the Sellick maneuver performed to enable endoscopic submucosal dissection

A 55-year-old male underwent endoscopic submucosal dissection (ESD), under general anesthesia and orotracheal intubation, of a 22 mm Paris 0-IIa+0-IIb lesion located in the greater curvature of the medium/distal antrum. It was not possible to start the procedure after several attempts due to permanent belching and inability to maintain adequate gastric distension. ESD was only feasible after performing the Sellick maneuver (manual pressure application at the cricoid cartilage to occlude the upper esophagus), which allowed sustained gastric distension throughout the procedure (60 minutes).
