Objective:
Diabetic ulcers are a significant healthcare challenge, capable of diminishing quality of life, lengthening hospitalisation stay, and incurring substantial costs for patients and healthcare systems. Erbium-doped yttrium-aluminum-garnet (Er-YAG) laser has been evolving as a prospective intervention for addressing wounds of various aetiologies. Despite this, the literature remains limited in appraising the effectiveness of laser therapy specifically in diabetic wounds. This study investigates the impact of employing a spatially modulated Er-YAG laser as a therapeutic approach for treating diabetic ulcers.
Method:
In a single-arm study conducted from November 2017 to April 2023, patients with hard-to-heal ulcers were treated in a two-step approach of wound debridement using Er-YAG laser for ablation and biostimulation through deep tissue resonance using RecoSMA (Multiline laser system, LINLINE MS, Latvia) laser technology. Ulcers received weekly laser treatment, together with routine care until healing occurred and were then followed up to observe any recurrence. The primary outcome measure was wound closure; the secondary outcome measures were time to closure, and the number of laser treatments required. Data related to sociodemographic details, size and number of diabetic ulcers, and number of sessions related to laser treatment were collected using a predesigned, pretested questionnaire before initiating the treatment.
Results:
A total of 59 patients attending the clinic during the study period with diabetic ulcers were included in the study. The mean wound surface area at baseline was 25.7cm2 (median: 12cm2). The average number of sessions of laser treatment required was 4.41, ranging from 1-11. The size of the ulcer reduced with each session of laser treatment. The diabetic ulcers healed completely at the end of the treatment, indicating the effectiveness of the Er-YAG/RecoSMA two-step approach.
Conclusion:
Spatially modulated erbium YAG laser is effective as a therapeutic approach for treating diabetic ulcers.
