How should saline be injected to elevate sessile polyps during an endoscopic procedure?

Injecting saline at the distal end for foregut lesions is a preferred technique for elevating sessile polyps during an endoscopic procedure. This method ensures that the polyp is lifted effectively and can provide a clear view for resection. By targeting the distal end, the saline can create a cushion of fluid that aids in separating the polyp from the underlying tissue without distorting the lesion. This elevation is critical for safe and effective removal, especially in the foregut where anatomical considerations may complicate the procedure.

This technique also allows for better access and visualization of the base of the polyp, minimizing the risk of leaving behind any residual tissue or causing unnecessary trauma to the surrounding mucosa.
