Researchers comparing maggots with a standard "hydrogel" in treating leg ulcers found little difference.

Recent excitement over using maggots to speed up healing and even reduce MRSA infections in leg ulcers seems to have been premature, they said.

The British Medical Journal study is the first to compare maggots with standard treatment.

Leg ulcers can be very difficult to treat and after use of high-compression bandages only about half are healed within 16 weeks.

One common treatment is to use a water-based gel to keep the wound moist and promote the natural healing process.

Maggots, or larval therapy, are another option - but it can be more tricky to place them in the wound and they have to be specially ordered which takes a few days.
