Laser speckle contrast analysis (LASCA): a new device in the diagnosis and monitoring of surgical treatment of hidradenitis suppurativa.

Introduction: Laser speckle contrast analysis (LASCA) is a quite new and unique device which can find applications in multiple diagnostic approaches in dermatology and dermatosurgery. LASCA can be used in multiple approaches. We would like to make the world's first presentation of LASCA usefulness in hidradenitis suppurativa (HS) surgery based on a case series. Aim: To evaluate the usefulness of LASCA in the surgical treatment of HS. Material and methods: In HS surgical treatment at the Centre for Burns Treatment in Siemianowice Slaskie, Poland in 2019-2022, we performed standard preoperative, intraoperative and postoperative speckle laser examinations to assess the vascular perfusion of the surgical sites. The device used was Laser Speckle Contrast Analysis (Perimed AG). This study included 18 patients treated surgically at the Centre for Burns Treatment in Siemianowice Slaskie with specific LASCA findings. Results: As a result of the LASCA examination, we found 1) ischemia of the flap, and 2) local foci of HS, and we could also assess the healing process. Conclusions: LASCA is a great device with which we can evaluate wound healing after surgical procedures (STSG and skin local flaps). LASCA allows for early detection of post-operative complications like ischemia of the local skin flap.

Co-Graft of Acellular Dermal Matrix and Split Thickness Skin Graft-A New Reconstructive Surgical Method in the Treatment of Hidradenitis Suppurativa.

Hidradenitis suppurativa is a chronic disease that significantly reduces patients' quality of life. Patients are chronically treated with systemic therapies, which are often ineffective. Surgical treatment for severe cases of hidradenitis suppurativa is one option for affected patients. Surgical treatment has its limitations, and wound closure may be particularly problematic. This requires the use of reconstructive techniques. The methods of choice for wound closure are split-thickness skin grafts or local flaps reconstructions. However, each method has its limitations. This is a presentation of a new reconstructive surgical method in hidradenitis suppurativa surgery: the use of a co-graft of Acellular dermal matrix and split thickness skin graft as a novel method in wound closure after wide excisions, based on two cases. The results of this method are very promising: we achieved very fast wound closure with good aesthetic results regarding scar formation. In this paper, we used several examinations: laser speckle analysis, cutometer tests, and health-related quality of life (QoL) questionnaire to check the clinical impact of this method. Our initial results are very encouraging. ADM with STSG as a co-graft could be widely used in reconstructive surgery. This is a preliminary study, which should be continued in further, extended research.
