Endoscopic Powder: A Game-Changer in Haemostasis for Minimally Invasive Surgery

Securing haemostasis effectively is essential for positive surgical outcomes. 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.

 

 

Why Bleeding Control in MIS is Difficult

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. The lack of space, restricted visibility, and absence of tactile cues make diffuse or irregular bleeding especially tough to address.

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
• 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

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

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.

 

 

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. 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

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
• Gynaecology MIS surgeries
• Endoscopic procedures like ESD
• Urological surgeries

Using endoscopic powder helps surgeons see better, stop bleeding quicker, and complete operations faster—often with less need for transfusions and better patient outcomes.

 

 

Clinical Evidence: Proven Performance of ORC Powder

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
• Excellent results across open and minimally invasive surgeries
• No complications such as rebleeding, thromboembolism, or side effects reported
• Surgeons found it easy to use, highly effective, and praised the precise delivery with little extra intervention needed

These findings confirm that SURGICEL® Powder is safe, efficient, and versatile, particularly for managing mild-to-moderate bleeding where traditional methods may fall short.

 

 

Summary

As MIS continues to evolve, so does the demand for advanced haemostatic tools. 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.
