Any infused/injected water rapidly mixes with any luminal blood and/or residue. But the viscous gel displaces luminal blood, clots and residue. Consequently, gel immersion endoscopy clarifies a bleeding source.

A large accessory channel with BioShield irrigator (US Endoscopy (STERIS), Ohio, United States) enables additional injection of gel with a therapeutic device in situ within the accessory channel.

The use of a distal attachment makes it easier to concentrate the gel in front of the scope.

Insufflation of the endoscope-balloon can stop a backflow of the gel, making it easier to push away blood, clots and residue.
Fig. 5
Fig. 5
The gel should be injected near the bowel wall, below the blood clots to clarify the bleeding point, especially in the stomach, because the bleeding originates from vessels on the wall. Injection in the center of lumen obscures the visual field.
