Revolutionizing Bleeding Control: The Impact of Endoscopic Powder in MIS
Effective control of haemostasis is critical to the success of any surgical procedure. Besides reducing bleeding, proper haemostasis cuts down the chances of transfusions and post-surgical issues. 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
While MIS offers benefits such as shorter recovery and less scarring compared to open surgery, it brings new challenges. These positive factors, however, increase the complexity of haemostasis. 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. 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.
Key Benefits of Surgi-ORC® Endoscopic Powder
• 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
• 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
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
The choice of delivery device plays a major role in the powder’s performance during MIS. 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. By manually compressing the bellows, surgeons can apply a consistent amount of haemostatic agent directly onto the bleeding site without obstructing the surgical view.
Maximizing Effectiveness: Usage Tips
• Orientation: The angle of device orientation (vertical vs. horizontal) has a significant impact on the amount and spread of the powder. Surprisingly, orientation often affects performance more than the speed or force of compression
• Physical Properties of Powder: Particle size, flow characteristics, and moisture sensitivity also influence output
• Application Style: The surgeon’s technique and compression force also influence powder delivery
Where Endoscopic Powder Excels in Practice
When working in tight spaces or near fragile tissues, endoscopic powder is especially useful. Its flexible form lets it cover both wide wounds and tight spaces with equal efficiency.
Typical Applications:
• Minimally invasive liver surgeries
• Cardiothoracic
• 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]
These findings confirm that SURGICEL® Powder is safe, efficient, and versatile, particularly for managing mild-to-moderate bleeding where Endoscopic Powder traditional methods may fall short.
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.
