FLOGEL® Enhancing Gentle Haemostasis in Endometriosis Care

FLOGEL® Enhancing Gentle Haemostasis in Endometriosis Care

 Endometriosis is a common, benign, estrogen-dependent condition affecting women of reproductive age. It often presents as ovarian endometriomas and may be associated with pelvic pain, dysmenorrhea, dyspareunia, infertility, or may be discovered incidentally during imaging or surgery.1,2

Surgical treatment options include fenestration with coagulation, laser vaporization, and laparoscopic cystectomy. Among these, cystectomy is generally considered the preferred approach, as it has been shown to reduce recurrence compared with drainage and ablation and is associated with better fertility outcomes.2,3 However, once the cyst is removed, achieving effective haemostasis from the ovarian bed can still be a challenging step in the procedure.

Why does the choice of haemostatic method matter in endometrioma surgery?

The method used to control bleeding during laparoscopic cystectomy for endometriosis can directly affect ovarian tissue. Choosing an approach that ensures effective haemostasis while minimizing tissue damage is essential to preserving ovarian function and long-term outcomes. After stripping the cyst wall, the subsequent bleeding of the ovarian stromal wound is usually controlled by bipolar coagulation or/and by suturing.4 The table below outlines the impact of different haemostatic methods on ovarian tissue.2–5

To make this step more tissue-friendly, surgeons are increasingly using topical haemostatic agents such as gelatin-based matrices (e.g., FLOGEL®). These agents help achieve effective bleeding control by promoting natural clot formation while minimizing trauma to the surrounding ovarian tissue, making them a useful support in ovarian endometrioma surgery.

What is FLOGEL®?


FLOGEL® is a flowable gelatin-based haemostatic matrix supplied in a prefilled syringe for fast bleeding control, usually within 2–5 minutes. The flowable nature of FLOGEL allows it to conform to irregular wound surfaces and reach difficult-to-access areas.

It closely adapts to the bleeding site and can be combined with thrombin to enhance and accelerate the body’s natural clotting process. By providing effective haemostasis without thermal injury, it offers a practical and tissue-friendly alternative to electrosurgical methods.

What does clinical evidence suggest?

A study of 20 patients undergoing laparoscopic endometrioma excision (cyst diameter 3–6 cm) compared haemostasis using a gelatin–thrombin matrix (n=8) with conventional haemostatic methods (bipolar forceps or CO₂ laser, n=12).

Key findings:3

Haemostasis was achieved in all cases within 3 minutes, with comparable outcomes to conventional methods (172 vs 182 seconds (about 6 minutes)) and no intra- or postoperative complications, bleeding, or transfusion requirements were reported.3

The study suggests that topical gelatin–thrombin matrix haemostatic agents may be a useful alternative to bipolar coagulation to reduce thermal damage to follicular or ovarian tissue and may help better preserve ovarian reserve after laparoscopic cystectomy for endometriosis.2,3

Conclusion:

FLOGEL® provides effective haemostasis during endometriosis surgery while avoiding thermal injury associated with bipolar coagulation. By supporting natural clot formation and minimizing damage to ovarian tissue, it may help preserve ovarian reserves following cystectomy. Its flowable, tissue-friendly design makes it a valuable adjunct for achieving gentle and effective haemostasis in ovarian endometrioma surgery.

Revolutionizing Surgical Hemostasis: Introducing Surgi-ORC® Powder (Absorbable Hemostatic Powder)

Image
  In modern surgery, efficiently managing perioperative bleeding is crucial. Uncontrolled surgical bleeding poses significant risks to patient health and leads to substantial clinical and healthcare resource burdens. This challenge is particularly pronounced with an aging population and the rising prevalence of comorbidities and anticoagulant use. To address these issues, topical hemostatic agents have emerged as vital tools, promoting hemostasis where conventional methods fall short. These agents vary widely in properties, mode of action, ease of use, safety, and cost. Their selection often depends on the specific surgical scenario, bleeding situation, and patient’s health status. Exploring Topical Hemostatic Agents The current array of topical hemostatic agents comprises several types, each designed to meet different needs in the surgical setting: Mechanical Agents:  These are regarded as the simplest, safest, and most cost-effective. They offer a structural framework for he...

Role of Surgi-ORC® Fibril and SURGISPON® in Posterior Fossa Tumor Resections

Image
  In posterior fossa tumor resections, Surgi-ORC® Fibril and SURGISPON® play crucial roles in facilitating a successful surgery and promoting optimal patient outcomes. Here's how they contribute to the surgical process: Hemostasis : One of the primary roles of both Surgi-ORC® Fibril and SURGISPON® is to assist in achieving hemostasis, which is the control of bleeding during surgery. Posterior fossa tumor resections can involve intricate procedures near sensitive structures such as the brainstem and cranial nerves, where bleeding must be carefully managed to maintain a clear surgical field and prevent complications. Surgi-ORC® Fibril and SURGISPON® are applied to bleeding surfaces to promote clot formation and minimize bleeding, thus enhancing visibility and surgical precision. Tissue Protection : During posterior fossa tumor resections, it's essential to protect delicate neural tissues from damage during surgical manipulation. Surgi-ORC® Fibril and SURGISPON® act as physical ba...
