APPLICATION OF THE GEL IMMERSION METHOD IN VARIOUS ENDOSCOPIC PROCEDURES

Abstract

The method of injecting a clear gel into the lumen, the gel immersion method, was first reported in 2016. The viscosity of the gel prevents it from rapidly mixing with blood, intestinal juice, and food residue. As a result, the space occupied by the gel provides a clear visual field. Viscoclear, the gel dedicated for this method, was launched in October 2020. In addition to endoscopic hemostasis, it has been used in other endoscopic procedures such as ESD, EMR, EUS, reduction of volvulus, and foreign body retrieval. Since the visual field can be secured even while the lumen is collapsed, the redundant scope loop is reduced and maneuverability is improved. A low intraluminal pressure is maintained; this may reduce the patientʼs discomfort and risk of complications.
