Summary
Platelet-rich plasma (PRP) therapy shows promise for treating recurrent anal fistulas, achieving a 60% closure rate. Preceding PRP with fistula drainage may improve outcomes in this sphincter-preserving approach.
Area of Science:
- Gastroenterology
- Regenerative Medicine
- Surgical Innovation
Background:
- Recurrent anal fistulas pose treatment challenges, often leading to complications like fecal incontinence.
- Sphincter-preserving techniques are increasingly favored to mitigate these risks.
Purpose of the Study:
- To evaluate the efficacy of platelet-rich plasma (PRP) therapy for recurrent cryptoglandular anal fistulas.
- To compare PRP efficacy with and without prior fistula drainage.
Main Methods:
- A prospective trial involving 18 patients with anal fistulas, divided into two groups.
- Group I received direct PRP injection; Group II received PRP after 7-day fistula drainage (polyurethane foam or negative pressure wound therapy).
- An average of three PRP doses were administered, with potential for more, and patients were followed for 12 months.
Main Results:
- Fistula closure rates were 50% in Group I and 70% in Group II.
- Overall, 60% of patients achieved fistula closure with PRP therapy.
- While not statistically significant, drainage prior to PRP application showed a trend towards better results.
Conclusions:
- Platelet-rich plasma (PRP) therapy achieved a 60% closure rate for recurrent anal fistulas, surpassing other sphincter-saving methods.
- Fistula drainage prior to PRP application is recommended for potentially enhanced outcomes.
- PRP therapy presents a promising novel treatment option for anal fistulas.

Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...

The platelet phase, the second stage of hemostasis, commences around 15-20 seconds after an injury. It follows and overlaps with the vascular phase, during which blood vessels constrict to minimize blood loss.
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...
