Abstract
Gastrointestinal luminal defects, including perforations, leaks and fistulae, pose persistent obstacles in endoscopic therapeutic interventions. A variety of endoscopic approaches have been proposed, with through-the-scope clipping (TTSC), over-the-scope clipping (OTSC) and suturing representing the main techniques of tissue apposition. However, the heterogeneity in defect morphology, the technical particularities of different locations in the gastrointestinal (GI) tract and the impact of various parameters on the final outcome, do not allow distinct conclusions and recommendations on the optimal approaches for defect closure, and, thus, current practice is based on endoscopists experience and local availability of devices. This review aims to collect the existing evidence on tissue apposition devices, in order to outline the role of every device on specific indications.
