Full-endoscopic dural repair using drain catheter: technical note

Abstract

Background: Repairing dural tears through a uniportal endoscopic approach presents significant technical challenges. This technical note describes a novel endoscopic suturing technique using standard instruments commonly available in most operating rooms. Method: We describe the instrument preparation, operative steps, and a case illustration. The dural suturing technique is performed using standard endoscopic instruments with a custom-made knot pusher adapted from a No. 8 surgical drain catheter. Conclusion: Our proposed surgical workflow and suturing technique enable effective endoscopic dural repair without the need for specialized equipment. It offers a practical solution that may reduce the need for conversion to open surgery.
