Dr.Sreedharan Muniandy: I Heard Your Center Use Worm For Treatment, Is That True?
Maggot therapy, also known as larval debridement therapy (LDT), is an FDA-approved medical treatment in which sterilized maggots (typically from the Lucilia sericata species, or green bottle fly) are applied to chronic or infected wounds. These maggots help remove dead tissue, fight infection, and stimulate healing.
How Maggot Therapy Works
1. Debridement: Maggots secrete enzymes that break down necrotic (dead) tissue into a semi-liquid form, which they then consume, leaving behind only healthy tissue.
2. Antimicrobial Action: They release antimicrobial compounds that help kill bacteria, including antibiotic-resistant strains like MRSA (Methicillin-resistant Staphylococcus aureus).
3. Wound Healing Promotion: The movement of the maggots stimulates the wound bed, encouraging new tissue growth and reducing inflammation.
Uses of Maggot Therapy
• Diabetic foot ulcers
• Pressure sores (bedsores)
• Venous leg ulcers
• Infected post-surgical wounds
• Necrotic wounds that do not respond to conventional treatment
Advantages
• Effective against biofilm-forming bacteria that resist antibiotics.
• Selective debridement—only dead tissue is removed, preserving healthy tissue.
• Faster wound cleaning compared to some conventional methods.
• Non-invasive and cost-effective.
Challenges & Limitations
• Psychological discomfort for some patients.
• Requires frequent dressing changes (every 48–72 hours).
• Availability and regulation issues in some regions.
• May not be suitable for patients with bleeding disorders or severe infections that need immediate surgical intervention.
Recent Developments
New research is exploring genetically modified maggots with enhanced wound-healing properties and maggot secretions as potential injectable treatments.
