A New Ligation Using the Double-loop Clips Technique Versus Traditional Techniques in the Treatment of Large Wounds After Endoscopic Resection

Feasibility of a New Ligation Using the Double-loop Clips Technique Versus Traditional Techniques in the Treatment of Large Wounds After Endoscopic Resection: a Prospective Randomized Controlled Study

Studies have shown that postoperative inflammation can be relieved by clipping the wound, and can reduce the bleeding rate and perforation rate.Scholars at home and abroad have proposed the use of adhesives and circular surgical lines to clamp the wound.In 2019, Satoshi Abiko and others proposed the use of double-loop clips technology to clamp the wound, and make double-loop clips of appropriate length outside the body.Therefore, our study is a prospective randomized controlled study to explore whether the double-loop clips technique is safe and effective for larger wounds in daily clinical work.
