Laparoscopic Extracorporeal Knot-Tying for Uterine Vessel Occlusion during Hysterectomy with Cervical Cerclage in Large Uteri
0 Views •
2025
Here, we introduce a novel approach-Laparoscopic Extracorporeal Knot-Tying for Uterine Vessel Occlusion during Hysterectomy with Cervical Cerclage in Large Uteri. A laparoscopic extracorporeal knot-pusher is used to perform cervical cerclage, achieving complete occlusion of uterine arteries. Thereafter, the corpus uteri are excised to enhance visibility and facilitate the operative field.

This procedure performs long-lasting in vivo intracellular recordings from single neurons during physiologically relevant cerebral states and after complete abolition of ongoing electrical activities, resulting in an isoelectric brain state. The physiological constants of the animal are carefully monitored during the transition to the artificial comatose condition.

Access for long-term infusion in the superior mesenteric artery (SMA) of rats is a surgical procedure that consists of cannulation of a proximal branch of the SMA. The cannula exits from the abdominal wound and is tunneled through the subcutaneous space back to the interscapular fold.
FAQs
The knot tightens through coordinated movement of its suture components. Interlocking loops surround the tissue or vessel, and traction on the standing end reduces the loop’s space around the target. This sliding action lets the ligature cinch after it has been positioned, making the relationship between loop structure and applied tension central to secure closure.
A knot pusher transfers the already formed knot along the suture toward the intended site. This matters when the operative field does not permit direct hand placement or intracorporeal tying. Advancing the knot allows the surgeon to position the ligature at tissue or vessel level, after which tightening the standing end supports closure or bleeding control.
Security depends on how the loops engage the suture and how the knot responds when the standing end is pulled. If the knot can be advanced and then cinched at the target, it supports consistent approximation or ligation. These features help clinicians judge whether Roeder’s knot is appropriate when reliable closure is required during minimally invasive surgery.
Its principal procedural distinction is that the knot can be formed and advanced without requiring direct intracorporeal knot tying at the target site. The knot pusher provides the advancement step, while the sliding design permits cinching after positioning. This can be useful in laparoscopic or endoscopic work, where access for manual tying is limited.
Deployment begins by placing the interlocking loops around the tissue or vessel to be ligated. The formed knot is then advanced along the suture with a knot pusher until it reaches the intended location. Pulling the standing end cinches the loops around that target. The resulting ligature can support vessel control or tissue approximation.
Clinicians may choose this approach when a minimally invasive procedure requires a ligature for secure closure, tissue approximation, or control of bleeding. The technique is especially relevant to laparoscopic and endoscopic procedures because it avoids dependence on direct intracorporeal tying. Its value lies in combining targeted placement with tightening suited to restricted operative access.
