Effectiveness of Through the Scope Dual Action Tissue Clips and X-tack Helix Suturing System for the Closure of Gastrointestinal Defects after Removal of Polyps
This clinical trial compares the effectiveness of Through the Scope (TTS) Dual Action Tissue (DAT) clips to the X-tack Helix suturing system as well as the ability to provide effective closure to gastrointestinal (GI) defects in patients undergoing removal of GI growths (polyps). Removal of polyps can prevent the development of cancer and may help avoid a more invasive surgical procedure. An endoscope, a thin, tube-like instrument with a light and a lens for viewing, is inserted through the mouth or anus and instruments are passed through channels within the endoscope to remove polyps. Once the polyp is removed , the left over tissue at the removal site (GI defects) can bleed. Closure of GI defects after resection can decrease the rate of bleeding. Closure of the GI defects can be done through the scope using DAT clips to clamp the edges of the tissue together. X-tack Helix suturing system uses tacks to secure the edges of the tissue together, with the first tack placed in the healthy tissue near the edge of the defect. Using through the scope DAT clips may be more effective than the X-tack Helix suturing system in closure of GI defects in patients undergoing removal of GI polyps.
