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
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. Reduced access, poor visualisation, and no sense of touch make handling bleeding in MIS more difficult.
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.
Spotlight on Surgi-ORC®-Based Endoscopic Powder
Among haemostatic powders, plant-based, absorbable types like Surgi-ORC® have demonstrated both safety and effectiveness. ORC was first introduced in 1943 in sheet form and has since evolved to meet the demands of modern MIS through powder formulations.
Why Surgi-ORC®-Based Endoscopic Powder Stands Out
• Effective Haemostasis: ORC facilitates platelet adhesion and aggregation to accelerate clotting
• Conformability: The powder’s granular shape adapts to wounds, covering both large and deep surfaces
• No Animal Content: Plant origin means reduced risk of allergic or infectious complications
• Antibacterial Environment: The oxidation process lowers pH, creating an acidic microenvironment that offers bactericidal benefits
• Biocompatible and Absorbable: Completely resorbed by the body with no cytotoxic effects, even near nerves or vessels
With these properties, Surgi-ORC® endoscopic powder is perfect for mild-to-moderate bleeding, particularly from capillaries, veins, or small arteries in hard-to-reach areas.
Optimizing Application with Delivery Devices in MIS
How the powder is delivered greatly influences its effectiveness in surgery. In MIS, bellows pump-based applicators are widely used to deliver endoscopic powder with accuracy and control.
How Bellows Applicators Function
These applicators—resembling syringe-like devices—are equipped with short or long applicator tips designed to deliver the powder through laparoscopic ports or trocars. The bellows mechanism lets surgeons deposit powder accurately without blocking the field of view.
Key Considerations for Optimal Use
• Orientation: How you hold the device (vertically or horizontally) influences powder distribution more than how hard you squeeze
• 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.
Common Uses Include:
• Minimally invasive liver surgeries
• Thoracic surgery procedures
• 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. 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.
