Endoscopic Full Thickness Resection in the Lower GI Tract With the "Full Thickness Resection Device"

• Conditions: Colorectal Adenomas; Submucosal Tumors
• Interventions: Device: Endoscopic full thickness resection (EFTR)

• Registration Number: NCT02362126
• Lead Sponsor: Kliniken Ludwigsburg-Bietigheim gGmbH

Brief Summary

Observational prospective multicenter study to investigate efficacy and safety of endoscopic full thickness resection in the lower GI tract using a novel over-the-scope full thickness resection device.

Detailed Description

The FTRD ("Full Thickness Resection Device", Ovesco Endoscopy, Tübingen, Germany) is an over the scope device consisting of a transparent cap with a preloaded monofilament snare and and a 14 mm modified Over-the-scope Clip. The device is CE marked for full thickness resection in the lower GI tract.

The study was designed to investigate efficacy and safety of this device for full thickness resection of colorectal lesions.
