Detailed 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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Cook medical EMR Gel

Prospective study involving excised human stomachs and colon harvested from sleeve gastrectomies and colectomies performed for benign or malignant disease.

Different Cook submucosal injections of varying viscosities will be injected into different areas of the excised stomachs or colons.

Data collected will involve lifting characteristics and dissection adequacy of the varying viscosities of gel.
Drug: Cook Medical EMR Gel
Cook Medical EMR Gel will be injected submucosally into ex-vivo gastric or colonic tissue specimens
Other Names:
  • Cook Medical EMR Gel will be injected submucosally

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Lift Efficacy
Time Frame: 1 hour
Lifting characteristics which would be measured by height of the mucosa after submucosal gel injection.
1 hour

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Dissection Adequacy
Time Frame: 1 hour
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
