Abstract

Objective: Our aim was to assess the effectiveness of stromal vascular fraction (SVF) in treating scars using the latest meta-analysis.

Methods: We used PubMed, Embase, Cochrane, and Web of Science to search the studies used to evaluate the efficacy of SVF in scar treatment. At least one of the following outcome measures were reported: vascularity, pigmentation, thickness, relief, pliability, surface area, pain, itching and color.

Results: A total of four eligible articles comprising 145 patients (64 SVF patients and 81 non-SVF patients) were included. The findings of this meta-analysis indicated that SVF had significant therapeutic effects in terms of vascularity (SMD/MD, 95% CI: -1.12, -0.02; p = 0.04), itching (SMD/MD, 95% CI: -0.61, -0.13; p = 0.002), POSAS (SMD/MD, 95% CI: -5.93, -1.47; p = 0.001), and thickness (SMD/MD, 95% CI: -1.04, -0.35; p < 0.001). In terms of OSAS (SMD/MD, 95% CI: -9.14, 0.59; p = 0.09), pigmentation (SMD/MD, 95% CI: -1.02, 0.06; p = 0.08), relief (SMD/MD, 95% CI: -1.14, 0.16; p = 0.14), surface area (SMD/MD, 95% CI: -0.91, 0.26; p = 0.27), PSAS (SMD/MD, 95% CI: -7.20, 0.49; p = 0.09), pain (SMD/MD, 95% CI: -0.87, 0.07; p = 0.10), pliability (SMD/MD, 95% CI: -0.57, 0.01; p = 0.06), and color (SMD/MD, 95% CI: -1.78, 0.48; p = 0.26), there were no significant statistical differences.

Conclusion: In view of the heterogeneity and potential selective bias, further large-scale, prospective, and multicenter clinical trials are needed to confirm the efficacy and reliability of SVF in the treatment of scars.

基质血管成分治疗疤痕的疗效：系统回顾与荟萃分析。

目的我们的目的是利用最新的荟萃分析评估基质血管成分（SVF）治疗疤痕的有效性：我们使用 PubMed、Embase、Cochrane 和 Web of Science 搜索了用于评估 SVF 治疗疤痕疗效的研究。至少报告了以下一项结果指标：血管、色素沉着、厚度、缓解、柔韧度、表面积、疼痛、瘙痒和颜色：结果：共纳入了四篇符合条件的文章，包括 145 名患者（64 名 SVF 患者和 81 名非 SVF 患者）。鉴于存在异质性和潜在的选择性偏差，需要进一步开展大规模、前瞻性和多中心临床试验，以确认 SVF 治疗疤痕的有效性和可靠性。

期刊介绍： Skin Research and Technology is a clinically-oriented journal on biophysical methods and imaging techniques and how they are used in dermatology, cosmetology and plastic surgery for noninvasive quantification of skin structure and functions. Papers are invited on the development and validation of methods and their application in the characterization of diseased, abnormal and normal skin. Topics include blood flow, colorimetry, thermography, evaporimetry, epidermal humidity, desquamation, profilometry, skin mechanics, epiluminiscence microscopy, high-frequency ultrasonography, confocal microscopy, digital imaging, image analysis and computerized evaluation and magnetic resonance. Noninvasive biochemical methods (such as lipids, keratin and tissue water) and the instrumental evaluation of cytological and histological samples are also covered. The journal has a wide scope and aims to link scientists, clinical researchers and technicians through original articles, communications, editorials and commentaries, letters, reviews, announcements and news. Contributions should be clear, experimentally sound and novel.
