Highlights

● Current innovation in gastrointestinal defect management falls into two main categories: clip-based mechanical compression devices and advanced high-precision endoscopic suturing systems. 

● Through-the-scope clips combined with auxiliary devices offer a strategic solution to overcome the size limitations inherent to single-device closure strategies for larger or complex defects. 

● Future technological development should focus on enhancing reliability, operability, cost-effectiveness, and overall user-friendliness of advanced endoscopic closure devices to broaden their clinical applicability.
