2025
In this video, we demonstrate suturing techniques — core suture and Q suture — to repair the foot flexor tendon in an ex vivo porcine model. Q sutures enhance the strength of the core suture in tendon repair and decrease gapping at the tendon repair site.

Source: Wang, L., et.al. Full-Endoscopic Isolation Zone Technique for the Treatment of Lumbar Disc Herniation. J. Vis. Exp.(2023)This video demonstrates a minimally invasive endoscopic procedure to treat lumbar disc herniation by removing the protruded nucleus pulposus and ruptured annulus fibrosus. The technique decompresses the affected nerve root, alleviates pain, and restores nerve function through targeted tissue resection and radiofrequency modulation.

Topical Airway Anesthesia for Awake-endoscopic Intubation Using the Spray-as-you-go Technique with High Oxygen Flow

2017
The topical anesthetic lidocaine was atomized using a high oxygen flow through the working channel of a flexible intubating endoscope to achieve topical airway anesthesia for awake endotracheal intubation. We prefer this modified spray-as-you-go technique for endoscopic intubation to classical bolus application because of higher patient satisfaction and better compliance.
FAQs
Successful closure depends on directing the needle across the tissue defect or between tissue layers, then bringing the suture edges into the intended position. The endoscope provides the access route, while the suture creates the approximating force. This coordinated movement allows the clinician to target the defect rather than broadly manipulate surrounding tissue.
After the thread has been passed, knots or a specialized closure device secure the approximation. This step converts a temporary suture position into a stable repair and can support different objectives, including closing a defect, reinforcing tissue, or addressing a procedure-related opening. The securing method therefore helps determine whether the tissue remains appropriately apposed.
Choosing whether to pass the needle across a defect or between tissue layers determines how tissues are brought together. A defect may require edge-to-edge approximation, whereas layer-to-layer placement can support reinforcement. This distinction matters because the method is not limited to one closure pattern; its value lies in matching suture placement to the tissue problem.
The workflow involves guiding the endoscope to the treatment site, directing the needle and suture to the selected tissue, passing the needle through or between the relevant surfaces, and securing the thread. The completed approximation, closure, or reinforcement then addresses the original defect or opening. These stages provide a minimally invasive alternative when conventional surgical access is undesirable.
Clinicians may consider this approach when a gastrointestinal perforation, mucosal defect, procedure-related opening, or selected bleeding source requires endoscopic treatment. It is also relevant when reinforcement is needed beyond an initial repair. The choice connects the local tissue problem with the goal of limiting access trauma while addressing the defect through an internal route.
In therapeutic endoscopy, the technique can provide targeted tissue closure, reinforcement, and control of selected bleeding sources. Its clinical significance comes from combining these repair functions with minimally invasive access. The result is not simply placement of a stitch, but support for tissue continuity at an internal site while reducing the access trauma associated with conventional surgery.
