Figure 1 Stage T1b of early esophageal cancer visualized by regular EUS (the schematic diagram on the right). The lesion and infiltration depth in the submucosa were difficult to distinguish from the mucosa.

Figure 2 Submucosal saline solution injection (SSI) enhanced EUS of stage T1b of early esophageal cancer (EEC). Stage T1b EEC of visualized in the SSI + EUS mode (the schematic diagram on the right). After SSI, the boundary between the mucosa and submucosa became clear. The lesion and infiltration depth in the mucosa and submucosa were easily distinguished.
