Endoscopic Suturing Devices: Apollo OverStitch and Beyond (2026)
Clinical Bottom Line
| Suturing Platform | Primary Mechanism | Top Clinical Indications |
|---|---|---|
| OverStitch (Apollo) | Full-thickness dual-channel suturing via a mounted cap. | Bariatric revisions, fistula closure, large mucosal defect securement. |
| Over-The-Scope Clips (OTSC) | High-compression nitinol bear-trap deployment. | Acute perforations, massive bleeding, recurrent ulcerations. |
| Endoscopic Tack Systems | Helical tacks driven into tissue (e.g., X-Tack). | Closure of wide ESD defects where opposing margins are distant. |
Full-Thickness Closure in Flexible Endoscopy
The capability to execute robust, full-thickness suturing through a flexible endoscope has fundamentally blurred the lines between advanced therapeutic endoscopy and minimally invasive surgery. The Apollo OverStitch system remains a cornerstone, allowing endoscopists to place continuous or interrupted full-thickness polypropylene sutures.
Clinical Applications
Endoscopic suturing is highly efficacious in the closure of iatrogenic perforations and full-thickness resections (EFTR). Furthermore, it drives the field of primary endoscopic bariatric therapies (e.g., Endoscopic Sleeve Gastroplasty) and the revision of dilated gastric bypass anastomoses. Advanced tactile feedback and motorized suturing platforms emerging in 2026 continue to lower the historically steep learning curve for these devices.
