Evaluation of Blood as a Submucosal Cushion During Endoscopic Polypectomy and Mucosal Resection

This study has been completed.
Sponsor:
Information provided by (Responsible Party):
Johns Hopkins University
ClinicalTrials.gov Identifier:
NCT00583466
First received: December 20, 2007
Last updated: September 11, 2017
Last verified: September 2017
  Purpose
For removal of large flat lesions of the gastro-intestinal tract injection of a solution under the lesion creates a "safety" cushion and protects from damage to the gastrointestinal tract wall. Various solutions are currently used, but some of them are easy to inject but quickly dissipate (normal saline),other solutions are more longer lasting (hydroxypropyl methylcellulose, hyaluronic acid, etc) but are very difficult to inject and can be expensive and not always available. The investigators performed previously animal experiments which demonstrated that blood is easy to inject and creates a protective cushion which lasts longer than other fluids which are currently used for protective cushion creation.

Condition Intervention Phase
Large Polyps in the Gastrointestinal Tract Drug: Autologous blood injection Drug: Normal saline Drug: HPMC Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Evaluation of Blood as a Submucosal Cushion During Endoscopic Polypectomy and Mucosal Resection

Further study details as provided by Johns Hopkins University:

Primary Outcome Measures:
  • Duration of the Submucosal Cushion [ Time Frame: Immediately after the procedure, Up to 5 minutes ]

Enrollment: 18
Actual Study Start Date: May 2007
Study Completion Date: May 2008
Primary Completion Date: May 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: 1 Normal saline arm
Polypectomy with normal saline injected for submucosal cushion creation
Drug: Normal saline
Normal saline will be injected under the lesion to create submucosal cushion
Active Comparator: 2 HPMC arm
Polypectomy after injection of hydroxypropyl methylcellulose (HPMC) to create submucosal cushion
Drug: HPMC
Hydroxypropyl methylcellulose (HPMC) will be injected under the lesion to create submucosal cushion
Experimental: 3 Blood arm
Polypectomy after injection of autologous blood
Drug: Autologous blood injection
Autologous blood will be drawn from the patient and then reinjected under the lesion to create a safety cushion

Detailed Description:
For removal of large flat lesions of the gastro-intestinal tract injection of a solution under the lesion creates a "safety" cushion and protects from damage to the gastrointestinal tract wall. Various solutions are currently used, but some of them are easy to inject but quickly dissipate (normal saline),other solutions are more longer lasting (hydroxypropyl methylcellulose, hyaluronic acid, etc) but are very difficult to inject and can be expensive and not always available. The investigators decided to use blood drawn from the patient for injection under the lesion. The investigators performed previously animal experiments which demonstrated that blood is easy to inject and creates a protective cushion which lasts longer than other fluids which are currently used for protective cushion creation. Blood can also have local hemostatic action preventing from bleeding during polypectomy.
