چکیده مقاله:

Abstract: Many chronic non-healing wounds require targeted approaches rather than the standard conventional therapies. Maggot debridement therapy (MDT) or the use of maggots to treat wounds is one such therapy that has been in use for centuries. Larvae of the green bottle fly Lucilia sericata are used in MDT. An important step in assisting chronic non-healing wounds progress through healing is wound bed preparation. This is usually achieved by effective debridement technique to remove devitalized tissue, including slough and eschar. The methods of debriding a wound can be classified as surgical, autolytic, mechanical, enzymatic, or biological. MDT mainly helps in wound healing by debridement of necrotic tissue by both mechanical and biochemical means. Mechanical debridement is achieved by the mouth hooks of the maggots and their rough bodies that scratch the necrotic tissue. They may also secrete a mixture of proteolytic enzymes that lyse nonviable tissue, making it easier for the maggots to digest. MDT can be used for any type of chronic wounds that have moist slough or necrotic tissue on its floor where urgent surgical debridement (eg, necrotizing fasciitis) is not indicated, possible or refused by the patient. MDT should be used cautiously under close supervision near exposed blood vessels, organs, or wounds body cavities. Bleeding complications have been encountered with previous use of MDT, and close observation of the therapy is required when used in patients with bleeding tendencies, for example, Warfarin induced coagulopathy. The use of maggot debridement therapy has provided an effective method for removing non-viable tissue and in some cases, preparing the wound bed for surgical reconstruction intervention in order to achieve wound healing and full closure
