Maggot debridement therapy in chronic wound care.Hong Kong Med J. 2007 Oct; 13(5):382-6.HK
To review the current evidence on the mechanism of actions and clinical applications of maggot debridement therapy.
Literature search of PubMed and Medline was performed up to January 2007.
Original and major review articles related to maggot debridement therapy were reviewed. Key words used in the literature search were 'maggot debridement therapy', 'wound healing', and 'chronic wound management'.
All relevant English and Chinese articles.
The mechanism of such maggot therapy was shown to be due to the debridement, disinfection, and wound healing enhancement actions of maggot excretions/secretions. The efficacy of maggot debridement therapy in chronic wound management has been demonstrated in chronic venous ulcers, pressure ulcers, and diabetic ulcers. There is also a new delivery system for the excretions/secretions, which has been shown to be as effective as using live maggots.
Maggot debridement therapy has been shown to be a safe and effective means of chronic wound management. However, there are a number of limitations when considering its local applicability. Future development of the delivery system may help to overcome some of these limitations and improve its acceptability.
