Adequate submucosal exposure and visibility are vital for effective and safe endoscopic submucosal dissection (ESD) [1]. For lesions located on the gravitational side, the mucosal flap tends to collapse as the dissection proceeds which hinders subsequent operation [2]. Position change for gravity assistance is usually preferred in this circumstance, but not always applicable [3]. In this case, we present use of the water pressure method (WPM) to facilitate ESD of a rectal tumor on the gravitational side close to the dentate line ([Video 1]).
