Extracorporeal shock wave therapy (ESWT) favors healing of diabetic foot ulcers: A systematic review and meta-analysis.

AIMS

To investigate the efficacy and safety of extracorporeal shockwave therapy(ESWT) for diabetic foot ulcers(DFUs).

METHODS

Search in PubMed, EMBASE, the Cochrane Controlled Register of Trials (CENTAL), and Web of Science for randomized controlled trials (RCTs) published before August 8, 2023. All identified studies were screened following the selection criteria. Finally, we employed the STATA 14.0 software for conducting a meta-analysis to evaluate the efficacy and safety of ESWT.

RESULTS

A total of ten RCTs with moderate methodological quality were included for data analysis. The findings showed that ESWT was significantly associated with significantly complete healed ulcers (risk ratio [RR]: 1.57, 95 % confidence interval [CI]:1.26 to 1.95) and lower rate of unchanged ulcers (RR: 0.25, 95 %CI: 0.14 to 0.42) compared to controls. Subgroup analysis further revealed that ESWT was better than both hyperbaric oxygen therapy (HOT) and the standard of care (SOC). Moreover, ESWT also significantly improved the average transcutaneous partial oxygen pressure (TcPO2) (mean difference[MD]: 1.71, 95 %CI: 1.22 to 2.19, p < 0.001). However, the rate of ≥ 50 % improved ulcers and treatment-emergent adverse events (TEAEs) were not significantly different between the ESWT and controls.

CONCLUSIONS

ESWT has shown promising efficacy and a favorable safety profile in the treatment of DFUs.
