Clinical Trial Summary

This is a study to determine how the viscosity (thickness) of an FDA approved gel affects the ease in which endoscopic mucosal resections (EMR) can be performed.

Description:

This is a study to determine how the viscosity (thickness) of an FDA approved gel made by Cook medical affects the ease in which endoscopic mucosal resections (EMR) - a type of endoscopic surgery performed for localised cancer - can be performed when the gel is injected submucosally. The lifting characteristics of the gel will be assessed by height and diameter and ease with which the subsequent EMR dissection can be performed. These characteristics would be assessed on excised human stomachs and colon, which are harvested during routine sleeve gastrectomy surgeries or colectomies, in an ex-vivo manner.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Lift Efficacy	Lifting characteristics which would be measured by height of the mucosa after submucosal gel injection.	1 hour
Secondary	Dissection Adequacy	Dissection adequacy which would be measured by time which the gel stays within the tissues. Anything less than one hour will be considered failure.	1 hour
