A Parallel Randomized Clinical Trial for Comparison of Two Methods of Maggot Therapy, Free-Range Larvae and Larval-bag, in Diabetic Ulcer (Wagner 2).

This article focuses on a randomized clinical trial comparing two formulations of maggot therapy—free-range larvae and larvae enclosed in a larval-bag—for treating Wagner grade 2 diabetic foot ulcers. The study found that free-range larvae of Lucilia sericata significantly reduced wound healing time and increased the rate of necrotic tissue removal compared to larvae confined in bags, with median debridement times of 4 and 9 days, respectively. Both methods were similarly acceptable to patients and medical staff, though larval-bag therapy may be preferable for wounds where free-range larvae are contraindicated due to safety or practical concerns. The findings suggest that while free-range larvae offer more rapid wound debridement, larval-bags provide a viable alternative with broader applicability in clinical settings.
