Endoscopic image showing superficial esophageal cancer, which was a flat lesion, 45 mm in diameter, located on the left midesophageal wall, and involving two-thirds of the circumference.

A good approach to the submucosal layer was secured due to the gel’s buoyancy.
Fig. 4
Fig. 4
Bleeding occurred slowly due to the gel’s viscous nature and further injection of the gel enabled good visualization (white arrow).
