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. 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. 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.
Conventional techniques like suturing, tying off vessels, or cauterization can be difficult to use during MIS. This is where topical haemostatic products—particularly endoscopic powders—are essential for boosting visibility and rapid bleeding control.
Spotlight on Surgi-ORC®-Based Endoscopic Powder
Surgi-ORC® endoscopic powder is a standout, plant-derived, absorbable haemostat with robust clinical backing. 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
• Fast Bleeding Control: ORC speeds up clotting by promoting platelet adhesion
• 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
• 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.
Delivery Devices: Enhancing Precision in MIS
The choice of delivery device plays a major role in the powder’s performance during MIS. Most MIS procedures rely on bellows-type applicators for controlled and accurate powder delivery.
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.
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
• Surgeon Technique: Output depends on the speed and force used when compressing the bellows
Clinical Uses 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.
Endoscopic Powder is Commonly Used For:
• Laparoscopic liver resections
• Thoracic surgery procedures
• Gynaecology MIS surgeries
• 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
Research on SURGICEL® Powder in 103 surgical patients found:
• 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, 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.
From deep pelvic cavities to exposed liver surfaces or tight endoscopic sites, ORC-based powder provides the safe, adaptable solution surgeons need.
