Abstract
There is a strong rationale to develop locally-acting surgical treatments for digital ulcers (DUs) in patients with systemic sclerosis (SSc). Our aim was to examine the safety and efficacy of local surgical management for SSc-DU.A systematic literature review was carried out until to August 2022 using 7 different databases. Original research studies concerning adult patients with SSc-DUs, and local surgical treatments were analysed using the PICO framework. We included randomized controlled trials, prospective/retrospective studies, and case series (minimum of 3 patients) References were independently screened by two reviewers including assessment of the risk of bias using validated tools.Out of 899, 13eligible articles were included. Autologous fat (adipose tissue AT) grafting was the surgical modality most identified (7 studies, 1 randomized controlled double blinded trial and 6 prospective open-label single arm studies). The healing rate (HR) with autologous fat grafting (4 studies) was 66-100 %. Three studies reported autologous adipose-derived stromal vascular fraction grafting: HR of 32-60 %. Bone marrow derived cell transplantation in a single study showed 100 % healing rate over 4-24 weeks. Surgical sympathectomy was examined in 3 studies, prospective without comparator with a median healing rate of 81 %. Two surgical studies (of direct microsurgical revascularisation and microsurgical arteriolysis) showed 100 % healing of ulcers, with no complications.Several surgical approaches for SSc-DUs have demonstrated some degree of safety and effectiveness for DU healing. However, there are significant methodological issues. Future studies are warranted to rigorously investigate surgical interventions for SSc-DUs.
