Objective:
This study aimed to systematically evaluate maggot debridement therapy (MDT) in the treatment of chronically infected wounds and ulcers.
Methods:
We performed a meta-analysis referring to the PRISMA statement (Preferred Reporting Items for Systematic Reviews and Meta-Analyses). We searched for published articles in the following databases: PubMed, Web of Science, Embase, Wanfang (Chinese), and the China National Knowledge Infrastructure (CNKI). The latest search was updated on March 14, 2014. For dichotomous outcomes, the effects of MDT were expressed as the relative risk (RR) and 95% confidence interval (CI). For continuous outcomes with different measurement scales, we calculated the standardized mean difference (SMD). The pooled effects were estimated using a fixed effect model or random effect model based on the heterogeneity test. Subgroup analyses were performed according to the types of wounds or ulcers.
Results:
MDT had a significantly increased positive effect on wound healing compared with conventional therapies, with a pooled RR of 1.80 (95% CI 1.24-2.60). The subgroup analysis revealed that the combined RRs were 1.79 (95% CI 0.95-3.38) for patients with diabetic foot ulcers (DFU) and 1.70 (95% CI 1.28-2.27) for patients with other types of ulcers. The time to healing of the ulcers was significantly shorter among patients treated with MDT, with a pooled SMD of -0.95 (95% CI -1.24, -0.65). For patients with DFU, the SMD was -0.79 (95% CI -1.18, -0.41), and for patients with other types of ulcers, the SMD was -1.16 (95% CI -1.63, -0.69).
Conclusion:
MDT not only shortened the healing time but also improved the healing rate of chronic ulcers. Therefore, MDT may be a feasible alternative in the treatment of chronic ulcers.
Insights
Maggot debridement therapy (MDT) significantly improves chronic wound healing rates and shortens healing time compared to conventional treatments. This makes MDT a promising alternative for managing chronic ulcers.
Area of Science:
- Wound Care
- Infectious Diseases
- Regenerative Medicine
Background:
- Chronic wounds and ulcers pose significant clinical challenges.
- Infected wounds require effective therapeutic interventions to promote healing.
- Maggot debridement therapy (MDT) is an alternative treatment modality.
Purpose of the Study:
- To systematically evaluate the efficacy of maggot debridement therapy (MDT) for chronic infected wounds and ulcers.
- To compare MDT outcomes against conventional therapies.
Main Methods:
- A meta-analysis was conducted following PRISMA guidelines.
- Searches were performed across major scientific databases (PubMed, Web of Science, Embase, Wanfang, CNKI).
- Dichotomous outcomes were analyzed using relative risk (RR), and continuous outcomes using standardized mean difference (SMD).
Main Results:
- MDT significantly increased wound healing rates (RR 1.80, 95% CI 1.24-2.60) compared to conventional therapies.
- Healing time was significantly reduced with MDT (SMD -0.95, 95% CI -1.24 to -0.65).
- Subgroup analyses showed efficacy in diabetic foot ulcers and other chronic ulcer types.
Conclusions:
- MDT effectively shortens healing time and improves healing rates for chronic ulcers.
- Maggot debridement therapy presents a feasible alternative for treating chronic ulcers.
