Tissue adhesives represent a group of natural and artificial compounds that are currently used for a variety of local applications including hemostasis, wound closure, and fistula repair. The most commonly utilized tissue adhesives in GI endoscopy include cyanoacry- lates, fibrin glues, and thrombin. Other adhesives, such as collagen-based sealants and PEG polymers, are beginning to be studied in various surgical disciplines and may one day find a role in endoscopic practice as well.
