Endoscopic Powder: A Game-Changer in Haemostasis for 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. In minimally invasive surgeries like laparoscopy or endoscopy, controlling bleeding is especially challenging due to limited space, visibility, and anatomical intricacy.
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
While MIS offers benefits such as shorter recovery and less scarring compared to open surgery, it brings new challenges. But the same factors that make MIS appealing also make bleeding control more difficult. Reduced access, poor visualisation, and no sense of touch make handling bleeding in MIS more difficult.
Traditional methods—sutures, ligation, or electrocautery—are often impractical in these settings. Here, topical haemostats such as endoscopic powders become essential, helping to control bleeding and improve surgical efficiency.
Spotlight on Surgi-ORC®-Based Endoscopic Powder
Among haemostatic powders, plant-based, absorbable types like Surgi-ORC® have demonstrated both safety and effectiveness. Introduced decades ago as a sheet, oxidized regenerated cellulose (ORC) is now available in powder form for today’s MIS challenges.
Key Benefits of Surgi-ORC® Endoscopic Powder
• Effective Haemostasis: ORC facilitates platelet adhesion and aggregation to accelerate clotting
• Shape Plasticity: The granular structure of powdered haemostats and their shape plasticity allows them to conform easily to large and deep surface wounds
• Plant-Based Safety: Free from animal or human components, it reduces risks of immune reactions and disease transmission
• Antibacterial Environment: The oxidation process lowers pH, creating an acidic microenvironment that offers bactericidal benefits
• Fully Absorbable: Powder dissolves safely, posing no harm to nerves or vessels
These characteristics make Surgi-ORC® endoscopic powder an ideal choice for managing mild to moderate bleeding—especially capillary, venous, or small arterial oozing in confined spaces.
Optimizing Application with Delivery Devices in MIS
The delivery method is a critical yet often overlooked factor in a powder’s haemostatic performance. In MIS, bellows pump-based applicators are widely used to deliver endoscopic powder with accuracy and control.
Operation of Endoscopic Powder Applicators
These applicators—resembling syringe-like devices—are equipped with short or long applicator tips designed to deliver the powder through laparoscopic ports or trocars. Compressing the bellows dispenses a controlled amount of powder right onto the bleed, maintaining clear visibility.
Maximizing Effectiveness: Usage Tips
• Device Orientation: The angle of application (vertical/horizontal) affects how the powder spreads—often more than compression speed
• Powder Properties: The grain size and flowability, plus moisture sensitivity, impact delivery
• Operator Technique: Delivery efficiency varies based on how quickly and forcefully the bellows are compressed [5]
Real-World Applications of Endoscopic Powder
In surgical settings where access is limited or structures are delicate, endoscopic powder proves invaluable. Its adaptability allows direct application to large, raw surfaces or narrow anatomical crevices.
Typical Applications:
• Minimally invasive liver surgeries
• Cardiothoracic MIS cases
• Laparoscopic gynaecologic interventions
• Endoscopic submucosal dissections (ESD)
• Urologic procedures
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:
• 87.4% haemostasis at 5 minutes, rising to 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, 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. Endoscopic powder, particularly ORC-based formulations, stands out as a reliable, fast-acting, and surgeon-friendly solution for bleeding control.
No matter the complexity—be it confined spaces, delicate organs, or irregular wounds—ORC endoscopic powder ensures safe, effective bleeding control for today’s surgical demands.
