Endoscopic Powder for Haemostasis: A Breakthrough in Minimally Invasive Surgery
The ability to achieve reliable haemostasis is vital in every surgical setting. It not only limits blood loss during surgery but also lowers risks of transfusion and complications after the procedure. However, in minimally invasive surgeries (MIS)—such as laparoscopic and endoscopic procedures—haemostasis presents unique challenges due to restricted access, limited visibility, and anatomical complexity.
As more procedures move toward minimally invasive methods, there’s a greater demand for flexible, effective bleeding control solutions when traditional methods aren’t enough.
Challenges of Haemostasis in Minimally Invasive Surgery
Minimally invasive surgery provides advantages including faster healing and minimal scarring, but also presents new obstacles for bleeding control. However, these benefits come with the challenge of difficult bleeding management. Limited maneuverability, constrained visualization, and the absence of tactile feedback make it harder to manage diffuse or irregular bleeding.
Conventional techniques like suturing, tying off vessels, or cauterization can be difficult to use during MIS. That’s where topical haemostatic agents, especially endoscopic powder, come into play as vital adjuncts to improve visibility, control oozing, and speed up procedures.
Understanding Surgi-ORC® Endoscopic Powder
One of the most promising powdered forms—a plant-based, absorbable haemostat with a proven safety and efficacy profile. Originally launched as a sheet in 1943, ORC has now been adapted into powder to address the needs of current minimally invasive surgeries.
Advantages of Surgi-ORC® Endoscopic Powder
• Accelerated Clotting: ORC’s mechanism enhances platelet activity and clot formation
• Adaptable Coverage: Powdered ORC easily conforms to irregular or deep wound areas
• Plant-Derived and Safe: No animal or human materials, so lower immune or infection risk
• Antibacterial Action: Acidic pH helps kill bacteria at the wound site
• Biodegradable and Safe: Powder is absorbed with no toxicity, even near sensitive structures
Thanks to these features, Surgi-ORC® powder excels at controlling bleeding from small vessels in restricted surgical fields.
Delivery Devices: Enhancing Precision in MIS
The choice of delivery device plays a major role in the powder’s performance during MIS. Bellows pump applicators are commonly used for precise powder placement in minimally invasive settings.
How Bellows Applicators Function
Bellows applicators, which look like syringes, have various tip lengths for applying powder via laparoscopic ports. By manually compressing the bellows, surgeons can apply a consistent amount of haemostatic agent directly onto the bleeding site without obstructing the surgical view.
Key Considerations for Optimal Use
• Orientation: How you hold the device (vertically or horizontally) influences powder distribution more than how hard you squeeze
• Physical Properties of Powder: Particle size, flow characteristics, and moisture sensitivity also influence output
• Operator Technique: Delivery efficiency varies based on how quickly and forcefully the bellows are compressed [5]
Real-World Applications of Endoscopic Powder
When working in tight spaces or near fragile tissues, endoscopic powder is especially useful. Because of its conformability, surgeons can treat both broad raw surfaces and deep crevices with ease.
Common Uses Include:
• Laparoscopic liver resections
• Thoracic surgery procedures
• Laparoscopic gynaecologic interventions
• Endoscopic procedures like ESD
• Urological surgeries
By enhancing visibility and enabling faster bleeding control, endoscopic haemostats can shorten operative time, reduce the need for blood products, and contribute to better surgical outcomes [6].
ORC Powder: Efficacy and Safety in Studies
A clinical study of SURGICEL® Powder (an ORC-based agent) on 103 patients revealed:
• Hemostasis was achieved in 87.4% of cases at 5 minutes, and 92.2% at 10 minutes
• Strong performance in open and minimally invasive settings
• No complications linked to the product: no rebleeding, clots, or negative reactions
• Surgeons rated it highly effective and easy to use, with precise powder delivery and minimal need for additional intervention [3]
This evidence supports the safety, Endoscopic Powder efficiency, and flexibility of SURGICEL® Powder for difficult bleeding scenarios.
Conclusion
With minimally invasive surgery on the rise, there’s a growing need for innovative bleeding control solutions. Among these, ORC endoscopic powder has proven to be both efficient and easy for surgeons to use.
From deep pelvic cavities to exposed liver surfaces or tight endoscopic sites, ORC-based powder provides the safe, adaptable solution surgeons need.
