How to close mucosal incisions?

This article provides an overview of the techniques for closure of the mucosal entry point following advanced procedures in the third space. The outbreak of natural orifice transluminal endoscopic surgery (NOTES) has significantly impacted the treatment of various benign and malignant conditions. Reliable and secure closure of the mucosal entrance is essential for avoiding serious adverse events.

Although small defects are typically closed using through-the-scope clips (TTSCs) or over-the-scope clips (OTSCs), challenges may occur with larger or transmural defects. Alternative methods, such as specialised stitches and full-thickness suturing systems, have been developed to address these challenges with promising results. Each method has its own pros and cons, and the choice of closure technique depends on various factors such as anatomical location, endoscopist expertise, costs, and clinical context.

By understanding the technical specifications of each closure device, endoscopists can make decisions that enhance patient outcomes and minimise the risk of complications associated with the approximation of defect edges. Continued research is essential to optimise the evolution of newer closure devices and techniques for advancing NOTES.
