Endoscopic Powder for Haemostasis: A Breakthrough in Minimally Invasive Surgery

Effective control of haemostasis is critical to the success of any surgical procedure. Beyond minimizing intraoperative blood loss, it significantly reduces the risks associated with transfusions and postoperative complications. Yet, minimally invasive surgeries—like laparoscopic and endoscopic interventions—make bleeding control more complex because of restricted maneuverability and visibility.
As surgical techniques continue to shift toward less invasive approaches, the need for effective, adaptable haemostatic solutions becomes increasingly critical—especially when conventional methods fall short.
The Haemostatic Challenge in MIS
Compared to open surgeries, MIS—such as laparoscopic and endoscopic procedures—offers numerous benefits like reduced recovery time and smaller scars. 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.
Suturing, tying, or cauterising are not always feasible in minimally invasive procedures. This is where topical haemostatic products—particularly endoscopic powders—are essential for boosting visibility and rapid bleeding control.
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
• Conformability: The powder’s granular shape adapts to wounds, covering both large and deep surfaces
• Plant-Derived and Safe: No animal or human materials, so lower immune or infection risk
• Bactericidal Properties: Acidic environment inhibits bacterial growth
• Biodegradable and Safe: Powder is absorbed with no toxicity, even near sensitive structures
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. 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. The bellows mechanism lets surgeons deposit powder accurately without blocking the field of view.
Key Considerations for Optimal Use
• Device Orientation: The angle of application (vertical/horizontal) affects how the powder spreads—often more than compression speed
• 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.
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:
• 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.
