Objective: Hidradenitis suppurativa (HS) is a chronic inflammatory disease of the hair follicle. Its treatment often requires a surgical approach. The aim of our study was to evaluate the occurrence of post-surgical complications following a new standard of surgical management. This included presurgical lesion mapping by ultra-high frequency ultrasound (UHFUS) with a 70MHz probe. Postoperative management was based on the principles of HS-TIME (time, inflammation/infection, moisture, edges)., Method: A single-centre, retrospective study was conducted by the Department of Dermatology of the University of Pisa. Patients with moderate and severe HS, refractory to previous medical and surgical therapies, were enrolled. All of the patients were treated with wide surgical excision of lesions, previously explored through a UHFUS evaluation with VEVO MD (Fujifilm VisualSonics, Inc., Canada) using a 48MHz and a 70MHz ultrasound probe. Following surgery, all patients were treated with secondary intention healing following the principles of HS-TIME. For each patient, we assessed the occurrence of post-surgical complications at follow-up visit six months after surgery. For each patient we assessed the occurrence of early post-surgical complications at every follow-up visit after surgery until complete wound healing. The occurrence of delayed complications was then assessed in all patients with an observation time after complete healing of >3 months (n=23)., Results: A total of 26 patients were enrolled in the study. There were no reported cases of post-surgical bleeding or haematoma occurrence, while three (11.5%) patients developed minor surgical site infection. The average severity of pain decreased from a numerical rating scale of 5.3 immediately after surgery to 1.3 after four weeks. The average healing time was 33.3±16.8 days, and only five (19.2%) patients reported a complete wound healing time of >6 weeks. Focusing on delayed complications: 1/23 (4.3%) patient had hypertrophic scarring; 2/23 (8.7%) patients reported dysaesthesia; and 2/23 (8.7%) cases of clinical relapse were reported. No cases of limited mobility at the surgery site were registered., Conclusion: The findings of the study demonstrated the efficacy of a novel surgical protocol, including a preoperative ultrasound evaluation and appropriate postoperative wound management. Further prospective studies are needed to validate the observed results; however, we conclude that the low recurrence rates and post-surgical complications confirmed that our proposed protocol would represent an effective strategy for the management of patients with HS eligible for surgical therapy.

Hidradenitis suppurativa (HS) presents challenges in management due to its chronic nature and high risk of recurrence. Post-surgical wound care plays a crucial role in treatment, even if standardized methods for assessing and predicting healing times are lacking. The aim of the study is to introduce the Wound Area Severity Index (WASI) as a novel tool to guide clinicians in assessing postsurgical wound progression and predicting potential healing times. A team of wound healing experts assessed 93 post-surgical HS wounds resulting from wide excision and secondary intention healing. For each wound healing time, wound area, wound bed score (WBS), and WASI were evaluated. WASI includes four parameters: area, temperature, depth and wound Bed, each with four severity levels. The total WASI score ranges from 4 to 16. Spearman correlation and Kruskal-Wallis tests were employed for statistical analysis. WASI strongly correlated with wound healing time (rho: 0.813, p < 0.001). Higher WASI scores were associated with prolonged healing, while lower scores indicated almost healed wounds. The WASI score has proven to be more highly predictive of healing times when compared to the individual parameter of the Area (moderate positive correlation, r: 0.77) and the WBS (negative correlation, r: -0.72). A total WASI score of 4 corresponded to a median healing time of 7 days, while a score exceeding 9 suggested a median healing time of 56 days. WASI has proven to be a valuable tool for assessing and predicting healing times in post-surgical HS wounds. Its simplicity, cost-effectiveness, and ability to integrate multiple parameters make it a promising addition to wound care practice., (© 2024 John Wiley & Sons A/S.

There is concern for increased risk of adverse events, particularly periprosthetic joint infection (PJI), following total joint replacement (TJR) in patients with hidradenitis suppurativa (HS) because of a compromised skin barrier and bacterial colonization of lesions. We used the TriNetX health research database to identify patients who had undergone TJR with (n = 1760) and without (n = 1760) HS matched by age, sex, ethnicity, race and risk factors for PJI. Multivariate analysis was performed and revealed that 90-day risk of PJI, reoperation, wound dehiscence, delayed wound healing, emergency room visits and readmission were not increased among patients with HS who underwent TJR. Given these findings, dermatologists and orthopaedists should not defer TJR access for patients with HS, as risk of postoperative complications is not prohibitive., Competing Interests: Conflicts of interest S.G.K. is an advisory board member/consultant for AbbVie, Aslan Pharmaceuticals, Arcutis Biotherapeutics, Castle Biosciences, Celldex Therapeutics, Galderma, Genzada Pharmaceuticals, Incyte Corporation, Johnson & Johnson, Leo Pharma, Novartis Pharmaceuticals Corporation, Pfizer, Regeneron Pharmaceuticals and Sanofi and has served as an investigator for Galderma, Incyte, Pfizer, and Sanofi.

Objectives: Hidradenitis suppurativa (HS) is a chronic inflammatory condition characterized by painful nodules, draining tunnels, and fibrotic scarring in intertriginous, hair-bearing areas. The pathogenesis involves follicular occlusion and subsequent rupture, leading to uncontrolled inflammation. Treatment options for HS are limited and lack universal effectiveness. Laser hair removal (LHR) has been explored as a potential treatment; however, the efficacy and appropriate laser modalities remain unclear. This systematic review examined the efficacy and adverse effects of LHR in HS., Methods: A comprehensive literature search was conducted from inception to September 2023 in Ovid MEDLINE, Ovid Embase, and The Cochrane Library (Wiley) with predefined inclusion and exclusion criteria, and a meta-analysis was conducted., Results: Ten studies were selected (n = 227 total patients) and included six randomized controlled trials, two nonrandomized experimental studies, and two case series. Various laser modalities, including long-pulsed neodymium-doped yttrium aluminum garnet (Nd:YAG) (n = 115), intense pulsed light (n = 18), Alexandrite (n = 54), intralesional 1064 nm diode (n = 20), and combined fractional CO 2 and long-pulsed Nd:YAG laser (n = 20), consistently demonstrated significant improvement in HS disease severity, irrespective of the disease scoring method used. Minimal adverse effects (primarily mild pain and erythema) were reported. A meta-analysis of three studies utilizing long-pulsed Nd:YAG laser demonstrated a standardized mean difference in disease severity of -1.68 (95% confidence interval: -2.99; -0.37), favoring treatment with LHR for HS., Conclusions: Hair follicles are key in HS pathogenesis and all included studies showed a significant improvement in HS disease severity after LHR regardless of the laser device used, likely related to hair follicle unit destruction. HS is a complex and heterogenous condition, and multiple disease scoring methods complicate outcome comparisons across studies. However, LHR, utilizing various techniques, is an effective treatment option for HS with minimal adverse effects., (© 2024 Wiley Periodicals LLC.)

Background: Hidradenitis suppurativa (HS) is a systemic inflammatory condition associated with obesity, metabolic syndrome, and environmental factors. Bariatric surgery (BS) is effective in reducing weight and resolving obesity-related medical problems., Objectives: The aim of this case-control study is to evaluate the effects of BS on the occurrence and recurrence of HS in individuals with obesity., Setting: Nationwide administrative data study using the French national discharge database., Methods: We compared 297,776 individuals with obesity and without a history of HS who underwent BS (BS group) with 2,735,930 individuals with obesity who did not receive BS (control group) to assess the incidence of de novo HS. From the same database, we compared hospitalization rates for HS recurrence between 310 individuals with obesity and HS who had BS (HS&#95;BS group) and 3875 individuals with obesity who did not have BS (HS&#95;control group). Propensity score matching using the nearest-neighbor method was implemented to create comparable patient groups., Results: Individuals with obesity and without a history of HS who received BS exhibited a significantly reduced risk of developing de novo HS (RR = .736 [.639; .847]). Among patients with a history of HS, those who underwent BS had a nonsignificantly reduced risk of HS recurrence (RR = .676 [.369; 1.238]) compared with those who did not., Conclusion: BS reduces the risk of developing de novo HS and seems to have a protective effect on its recurrence in individuals with obesity, although the latter effect was not statistically significant., (Copyright © 2024 American Society for Metabolic and Bariatric Surgery.

Background: Hidradenitis suppurativa (HS) is a painful, chronic inflammatory skin condition. Patients experience exacerbations, leading them to present to the emergency department (ED) for incision and drainage. Direct injection of local anesthetic into these lesions is extremely painful and seldom provides adequate anesthesia. A modified method of the PECS II block can provide anesthesia to the skin of the axilla, making management of HS much less painful for the patient. We performed a bilateral modified PECS II block on a patient requiring incision and drainage of HS lesions in both axillae. She subsequently required no local anesthetic for the procedure., Discussion: The second injection of the traditional PECS II block involves the deposition of anesthetic in the fascial plane between the pectoralis minor muscle and the serratus anterior muscles. This injection targets the lateral branch of the intercostal nerves, which provide sensory innervation to the axilla., Conclusions: A modified technique of the PECS II block, in which only the second injection is performed, is a potentially effective method for anesthetizing the axilla of patients with HS prior to incision and drainage., Competing Interests: Declaration of competing interest None., (Copyright © 2024 Elsevier Inc.

Pilonidal disease and hidradenitis suppurativa affect healthy young adults, causing discomfort and pain that leads to loss of work productivity and should be approached in a personalized manner. Patients with pilonidal disease should engage in hair removal to the sacrococcygeal region and surgical options considered. Hidradenitis suppurativa can be a morbid and challenging disease process. Medical management with topical agents, antibiotics, and biologics should be used initially but wide local excision should be considered in severe or refractory cases of the disease., Competing Interests: Disclosures Authors have nothing to disclose., (Published by Elsevier Inc.)

Background and Aims: Hidradenitis suppurativa (HS) is an inflammatory skin disease affecting apocrine gland-bearing sites of the body. Radiofrequency (RF) is a minimally invasive method that acts by minimizing thermal damage to the dermis, resulting in collagen synthesis and scar improvement. We systematically reviewed the efficacy and safety of RF in treating HS., Methods: A systematic search was performed up to November 18th, 2023, in PubMed/Medline, Ovid Embase, and Web of Science. Clinical studies with English full texts were included. The National Institute of Health (NIH) Quality Assessment Tool for clinical trials and Methodological quality and synthesis of case series and case reports by Murad et al. were utilized for critical appraisal., Results: Out of 55 identified studies, 11 met our inclusion criteria with 167 subjects who underwent RF therapy alone or combined with an intense pulsed laser (IPL), known as LAight®. LAight® significantly improved clinical outcomes in mild-to-moderate HS patients based on the Dermatology Life Quality Index (DLQI), International Hidradenitis Suppurativa Score System (IHS4), Pain-Numerical Rating Scale (NRS), and Hidradenitis Suppurativa Clinical Response (HiSCR). Moreover, RF therapy alone significantly alleviated the clinical manifestations in patients with mild-to-moderate HS. Additionally, fractional microneedling RF significantly decreased HS-associated inflammatory markers. RF was found to be safe with limited adverse events. However, in moderate-to-severe HS, RF has failed to yield satisfactory results., Conclusion: RF is a safe energy-based method with promising outcomes, especially for long-term application in mild-to-moderate HS. In moderate-to-severe cases, RF should be combined with a systemic medication for further beneficial impacts., (© 2024.

Hidradenitis suppurativa (HS) is an inflammatory follicular dermatological condition that typically affects the intertriginous and anogenital regions of the apocrine gland-bearing skin. The management of this chronic and recurring disease necessitates a combination of lifestyle changes, medication, and surgical approaches to achieve the best possible outcomes. While medical treatments are recommended for this multimodal disease, surgical therapy, which is the gold standard of treatment for HS, has proven to be the most effective treatment because it provides long-lasting local disease control, reduces the recurrence of lesions, and ensures complete healing of lesions. In the last decade, there has been exponential growth in research into various surgical techniques and reconstructive care, enabling patients to have more surgical options. There is a wide range of surgical management procedures available, such as incision and drainage, deroofing, excisional surgery, carbon dioxide laser therapy, and skin tissue-sparing excision with electrosurgical peeling. Among these surgical procedures, wide surgical excision is the best option since it can eradicate all the affected lesions. Meanwhile, the preferred approach to reconstruction at various anatomical locations remains debatable. Here, we review a variety of surgical treatments and reconstructive techniques for HS, particularly various flap techniques for the axillary, gluteal, and inframammary regions., (© 2024.

Introduction: Hidradenitis suppurativa (HS) is a recurrent, debilitating, chronic disorder of the pilosebaceous unit. Although advances in HS treatment have been made, more than 45% of patients remain dissatisfied with systemic treatment, and more than one-third are dissatisfied with surgical procedures., Objectives: A prospective, observational study on the deroofing procedures in HS with special attention paid to patient satisfaction and complications., Methods: HS lesions were assessed clinically and by the use of ultrasound. Patients reported outcomes, including pain, itch and satisfaction, were measured at 24 h post-surgery by a numeric rating scale (NRS) ranging from 0 to 10. Additionally, the timeline of objective wound closure reported by patients in (weeks), in addition to the need for any analgesics use, were both evaluated., Results: The mean closure time of the post-deroofing wound was assessed as 4.4 ± 1.9 weeks. A statistically longer time was necessary for complete closure in males than in females (4.9 ± 2.2 weeks and 3.9 ± 1.6 weeks, respectively; p = 0.046). The closure time correlated positively yet weakly with the HS tunnel's width (r = 0.27, p = 0.016) and length (r = 0.228, p = 0.044). Patients assessed mean pain at 24 h post-op as mild with 0.7 ± 1.2 points according to NRS, with no differences between sexes. Similarly, itch in the first 24 h was assessed as mild with 1.8 ± 1.1 points, without differences between sexes. No pain, itch or adverse events were reported after 1 week following deroofing. Moreover, no cases of wound infection were reported. An overall patient satisfaction was assessed as 9.9 ± 0.4 points (range 9-10 points)., Conclusion: Deroofing is an easy, effective and safe dermatosurgical procedure that does not require surgical experience or operating theatre. It is associated with no complications and very low post-op pain and should be part of holistic HS management., (© 2024 European Academy of Dermatology and Venereology.)

Background: Hidradenitis suppurativa (HS) is a debilitating chronic skin disease; its therapeutic approach often requires combined medical and surgical treatment., Methods: The aim of this study was to assess the efficacy and safety of the surgical approach combined with different pharmacological treatments, evaluating the proportion of patients achieving the hidradenitis suppurativa clinical response (HiSCR), along with the incidence of postoperative complications, and local recurrence. A retrospective study of HS patients (Hurley I-III) presenting at least one skin lesion requiring surgery was performed. Demographic and clinical data were collected (kind and anatomical location of lesion excised, type of surgical procedure). Further data included: Hurley stage and IHS4 at baseline and week 16, HiSCR at week 16 after surgery, ongoing therapy at the time of surgery (topical, systemic antibiotic, biologics), postoperative complications and local recurrence at week 16., Results: Forty-two patients with female predominance (66.7%, 28/42), with a mean age of 30.3 (SD±10.5) years, were enrolled. At week 16, 53% of patients achieved HiSCR, with baseline Hurley III inversely related to HiSCR achievement (P<0.05). No increased incidence of postoperative complications was detected. Three cases of local recurrence were reported at week 16., Conclusions: The results support the efficacy and safety of the combined therapy in the management of HS; no increased risk of complications emerged among patients concomitantly treated with biologics, compared to those on conventional systemic therapy or exclusively treated with surgery.

Hidradenitis suppurativa (HS) is a severe, debilitating, chronic inflammatory skin disease characterized by recurrent painful nodules, abscesses and draining sinus tracts in intertriginous areas. While this condition appears to stem from follicular unit dysfunction, its cause is multifactorial and the exact pathogenesis has yet to be fully elucidated. These factors make treatment selection challenging and contribute to variable therapeutic response among affected patients. Typical regimens consist of a combination of medical and surgical modalities, tailored to individual responses. However, HS is often refractory to traditional treatments, prompting the need for newer and more effective therapies. Herein, we review current and emerging HS therapies., Competing Interests: The authors have no conflicts of interest to declare.

Background: Hidradenitis suppurativa (HS) is a chronic, painful disease affecting flexures and other skin regions, producing nodules, abscesses and skin tunnels. Laser treatment targeting hair follicles and deroofing of skin tunnels are standard HS interventions in some countries but are rarely offered in the UK., Objectives: To describe current UK HS management pathways and influencing factors to inform the design of future randomized controlled trials (RCTs)., Methods: THESEUS was a nonrandomized 12-month prospective cohort study set in 10 UK hospitals offering five interventions: oral doxycycline 200 mg daily; oral clindamycin and rifampicin both 300 mg twice daily for 10 weeks, extended for longer in some cases; laser treatment targeting hair follicles; deroofing; and conventional surgery. The primary outcome was the combination of clinician-assessed eligibility and participant hypothetical willingness to receive each intervention. The secondary outcomes were the proportion of participants selecting each intervention as their final treatment option; the proportion who switch treatments; treatment fidelity; and attrition rates. THESEUS was prospectively registered on the ISRCTN registry: ISRCTN69985145., Results: The recruitment target of 150 participants was met after 18 months, in July 2021, with two pauses due to the COVID-19 pandemic. Baseline demographics reflected the HS secondary care population: average age 36 years, 81% female, 20% non-White, 64% current or ex-smokers, 86% body mass index ≥ 25, 68% with moderate disease, 19% with severe disease and 13% with mild disease. Laser was the intervention with the highest proportion (69%) of participants eligible and willing to receive treatment, then deroofing (58%), conventional surgery (54%), clindamycin and rifampicin (44%), and doxycycline (37%). Laser was ranked first choice by the greatest proportion of participants (41%). Attrition rates were 11% and 17% after 3 and 6 months, respectively. Concordance with doxycycline was 52% after 3 months due to lack of efficacy, participant choice and adverse effects. Delays with procedural interventions were common, with only 43% and 26% of participants starting laser and deroofing, respectively, after 3 months. Uptake of conventional surgery was too small to characterize the intervention. Switching treatment was uncommon and there were no serious adverse events., Conclusions: THESEUS has established laser treatment and deroofing for HS in the UK and demonstrated their popularity with patients and clinicians for future RCTs., Competing Interests: Conflicts of interest J.R.I. receives a stipend as Editor-in-Chief of the British Journal of Dermatology and an authorship honorarium from UpToDate.

Genital lymphoedema is a rare but debilitating and disfiguring complication of longstanding hidradenitis suppurativa (HS). Despite the existence of medical and surgical methods that offer varying success rates in a limited number of cases, no data exist about the use of complex decongestive therapy (CDT) in HS-related genital lymphoedema. This case report describes the treatment and outcome of a 56-year-old male patient with severe scrotal lymphoedema due to underlying HS (Hurley stage 3). The patient was unresponsive to various topical and systemic antibiotics and biological agents, including adalimumab and certolizumab pegol. When the patient was assessed, ixekizumab treatment for his HS was planned. He had progressive oedema in the genital area for two years with difficulty in wearing trousers and having sexual intercourse, and painful urination. CDT was recommended for three days a week concurrently with ixekizumab treatment. The patient and his wife were also educated about self-drainage techniques and skincare maintenance. After six sessions of CDT over 14 days, the patient demonstrated a significant reduction in scrotal measurements. He achieved a better scrotal contour, the degree of the buried penis was decreased, and urination was easier and painless. The findings of this case report showed that CDT was an easily applicable, practical and promising method that offered a rapid treatment response for HS-related genital lymphoedema.

Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease with a relapsing nature that has a significant impact on the patient's quality of life. The clinical presentation of the disease includes deep dermal abscesses and sinus tracts. Long-term affliction of the disease may lead to contractures, scars and fibrosis. Management is still challenging and varies from medical to surgical options. We report the following case of a man in his 30s who presented with severe HS in the axillae, groins, perineum and lower sacral region. The patient has been treated by excision of the whole lesions followed by using multiple fasciocutaneous flaps as a reconstructive method., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2023.

Purpose: Hidradenitis suppurativa (HS) is a chronic inflammatory disease characterized by painful and foul-smelling cystic nodules and sinus tracts in the apocrine gland-bearing regions. The treatment options include topical, intralesional, systemic, and surgical modalities. Currently, the most novel therapy is laser therapy to provide localized treatment without systemic adverse effects. However, data regarding patient outcomes after laser treatment are limited because of the low prevalence of this disease. This study aimed to evaluate the efficacy of laser therapy as a treatment modality for patients with HS., Methods: A retrospective review cohort analysis of patients with HS undergoing laser treatment between 2016 and 2021 was conducted. Patient demographics, lesion location(s), Hurley stage, age of onset and diagnosis, treatment length, type, outcomes, and complications were analyzed., Results: Ninety-four patients met the inclusion criteria; on average, patients were treated with 5.8 laser sessions for 14.8 months with no complications and minor blood loss. Hidradenitis suppurativa progression commonly starts during puberty, with a median onset of 13.8 years and diagnosis of HS at 16.2 years. All patients (n = 94) showed an improvement in HS disease severity: 59.6% completed treatment, 12.0% are currently undergoing treatment, and 26.0% were lost to follow-up., Conclusions: Laser therapy is an effective and safe therapy for HS leading to improved quality of life and should be considered in the treatment and management of HS., (Copyright © 2023 Wolters Kluwer Health, Inc.

Otherwise known as Verneuil's disease, hidradenitis suppurative (HS) is a severe dermatosis of heterogeneous appearance affecting 1% of the population. Its pathophysiology is multifactorial, involving genetic predisposition, inflammatory disorder and environmental elements. Its diagnosis is based on the association of three clinical characteristics: characteristic lesions, typical localizations, and the chronic and recurrent nature of the lesions. Given its diversified aspects, diagnosis can be difficult to achieve. As its manifestations often include abscesses, it is important for the surgeon to know how to detect this pathology. The development of biologics has improved treatment of this disease, treatment that necessitates a multidisciplinary medical and surgical approach involving dermatologists and proctologists as well as surgeons. The objective of this report is to synthesize what a surgeon will need to know so as effectively treat HS patients., (Copyright © 2023 Elsevier Masson SAS. All rights reserved.)

Background: Hidradenitis suppurativa is a chronic inflammatory skin disease characterised by recurrent inflammatory lesions and skin tunnels in flexural sites such as the axilla. Deroofing of skin tunnels and laser treatment are standard hidradenitis suppurativa interventions in some countries but not yet introduced in the United Kingdom., Objective: To understand current hidradenitis suppurativa management pathways and what influences treatment choices to inform the design of future randomised controlled trials., Design: Prospective 12-month observational cohort study, including five treatment options, with nested qualitative interviews and an end-of-study consensus workshop., Setting: Ten United Kingdom hospitals with recruitment led by dermatology and plastic surgery departments., Participants: Adults with active hidradenitis suppurativa of any severity not adequately controlled by current treatment., Interventions: Oral doxycycline 200 mg once daily; oral clindamycin and rifampicin, both 300 mg twice daily for 10 weeks initially; laser treatment targeting the hair follicle (neodymium-doped yttrium aluminium garnet or alexandrite); deroofing; and conventional surgery., Main Outcome Measures: Primary outcome was the proportion of participants who are eligible, and hypothetically willing, to use the different treatment options. Secondary outcomes included proportion of participants choosing each of the study interventions, with reasons for their choices; proportion of participants who switched treatments; treatment fidelity; loss to follow-up rates over 12 months; and efficacy outcome estimates to inform outcome measure instrument responsiveness., Results: Between February 2020 and July 2021, 151 participants were recruited, with two pauses due to the COVID-19 pandemic. Follow-up rates were 89% and 83% after 3 and 6 months, decreasing to 70% and 44% at 9 and 12 months, respectively, because pandemic recruitment delays prevented all participants reaching their final review. Baseline demographics included an average age of 36 years, 81% female, 20% black, Asian or Caribbean, 64% current or ex-smokers and 86% with a raised body mass index. Some 69% had moderate disease, 19% severe disease and 13% mild disease. Regarding the study's primary outcome, laser treatment was the intervention with the highest proportion (69%) of participants who were eligible and hypothetically willing to receive treatment, followed by deroofing (58%), conventional surgery (54%), the combination of oral clindamycin and rifampicin (44%) and doxycycline (37%). Considering participant willingness in isolation, laser was ranked first choice by the greatest proportion (41%) of participants. The cohort study and qualitative study demonstrated that participant willingness to receive treatment was strongly influenced by their clinician. Fidelity to oral doxycycline was only 52% after 3 months due to lack of effectiveness, participant preference and adverse effects. Delays receiving procedural interventions were common, with only 43% and 26% of participants commencing laser therapy and deroofing, respectively, after 3 months. Treatment switching was uncommon and there were no serious adverse events. Daily pain score text messages were initiated in 110 participants. Daily responses reduced over time with greatest concordance during the first 14 days., Limitations: It was not possible to characterise conventional surgery due to a low number of participants., Conclusion: The Treatment of Hidradenitis Suppurativa Evaluation Study established deroofing and laser treatment for hidradenitis suppurativa in the United Kingdom and developed a network of 10 sites for subsequent hidradenitis suppurativa randomised controlled trials., Future Work: The consensus workshop prioritised laser treatment and deroofing as interventions for future randomised controlled trials, in some cases combined with drug treatment., Trial Registration: This trial is registered as ISRCTN69985145., Funding: This award was funded by the National Institute for Health and Care Research (NIHR) Health Technology Assessment programme (NIHR award ref: 12/35/64) and is published in full in Health Technology Assessment ; Vol. 27, No. 30.

Hidradenitis suppurative is a chronic, refractory and recurrent dermatological disease. The disease should be managed by targeted surgical intervention on the basis of medical treatment. Currently, the surgical treatment methods include local treatments like incision and drainage, unroofing, laser therapy, intense pulsed light therapy, photodynamic therapy, as well as complete lesion resection such as skin-tissue saving excision with electrosurgical peeling and extended excision. The clearance range, therapeutic effect, postoperative complications, and recurrence risk vary among the different treatment methods. Local treatments cause less damage, but have high recurrence rates, and are mainly for mild to moderate hidradenitis suppurative patients. Complete lesion resections have relatively low recurrence rates, but may bring more surgical injuries, and postoperative reconstructions are needed, which are mainly for moderate to severe hidradenitis suppurative patients. In this article, the surgical treatment principles and various surgical treatment methods of hidradenitis suppurative are reviewed, to provide a reference for the diagnosis and treatment of this disease in clinical practice.

Background: Hidradenitis suppurativa (HS) is a common chronic condition that is often resistant to conservative treatment and requires a wide and aggressive surgical approach to prevent recurrence. A prospective study was performed comparing the outcomes of thoracodorsal artery perforator (TDAP) flap-based reconstruction and secondary intention closure (SIC) after wide local excision (WLE) of axillary HS., Methods: A prospective study was conducted on 68 patients with stage 3 axillary HS. Thirty-three patients underwent a WLE procedure and were left to heal by secondary intention (SIC group), and 35 patients underwent immediate reconstruction with a homolateral TDAP flap (TDAP group). Inpatient stay, healing time, postoperative complications rate, and pain were analyzed in both groups, comparing preoperative shoulder function (using Constant-Murley shoulder outcome score) and quality of life (using a dermatology life quality index) with postoperative shoulder function and quality of life., Results: Patients receiving TDAP flaps had significantly faster recovery, fewer complications, and fewer overall number of procedures than those who underwent SIC. All patients reported an improved quality of life after their operation. The TDAP group showed significantly more improvement than the SIC group ( P < 0.001). Patients receiving TDAP flaps reported a significant reduction in pain and discomfort and better shoulder function compared with patients in the SIC group ( P < 0.001)., Conclusions: WLE and TDAP flap-based reconstruction for axillary stage 3 HS provide optimal postprocedural functional results with a low complication rate. Complete remission of the disease was observed after the procedure. Despite the relatively slow learning curve of this procedure, the authors strongly recommend this technique as a very good option for the management of stage 3 axillary HS., Clinical Question/level of Evidence: Therapeutic, II., (Copyright © 2023 by the American Society of Plastic Surgeons.)

Background: Adalimumab, the only biologic registered for hidradenitis suppurativa, shows clinical response in up to 60% of patients, leaving many patients in need for other treatment options such as surgery., Objective: To compare the clinical effectiveness of adalimumab combined with surgery vs adalimumab monotherapy in patients with moderate to severe hidradenitis suppurativa., Methods: A pragmatic Randomized Controlled Trial was performed from August 2018 to July 2022. Primary outcome was the difference in mean International Hidradenitis Suppurativa Severity Score System reduction after 12 months of treatment with the difference in mean Dermatology Life Quality Index reduction as a key secondary outcome., Results: Thirty-one patients were included per arm. The mean International Hidradenitis Suppurativa Severity Score System at baseline was 23.9 ± 10.7 in the surgery group and 20.9 ± 16.4, in the monotherapy group. After 12 months of treatment the surgery group had a significantly greater reduction in International Hidradenitis Suppurativa Severity Score System compared with the monotherapy group (-19.1 ± 11.3 vs -7.8 ± 11.8, P < .001). Moreover, the surgery group showed a greater reduction in Dermatology Life Quality Index after treatment compared with the monotherapy group (-8.2 ± 6.2 vs -4 ± 7.7, P = .02)., Limitations: The study follow-up was too short to assess surgical recurrence rates., Discussion: Combining adalimumab with surgery resulted in greater clinical effectiveness and improved quality of life after 12 months in patients with moderate to severe hidradenitis suppurativa., Competing Interests: Conflicts of interest None disclosed., (Copyright © 2023 American Academy of Dermatology, Inc.

Treatment of hidradenitis suppurativa (HS) requires a combination of medical, surgical, and lifestyle interventions. Intense pulsed light (IPL) and lasers have been reported to be useful. The aim of this review is to find the evidence supporting IPL and laser treatment of HS and to provide guidance for the management of specific HS lesions. We searched PubMed and Web of Science for "laser" and "hidradenitis suppurativa" on April 6, 2022. Inclusion criteria were >10 patients, reported follow-up, English language, and human subjects with a diagnosis of HS. A total of 724 articles were screened, but only 17 studies qualified for inclusion (IPL (n = 4), Nd:YAG (n = 6), CO 2 laser (n = 6), and intralesional treatment (n = 2). The majority of the studies had a low (n = 10) or moderate (n = 7) evidence level. Treatment effect was noticed in studies using IPL and Nd:YAG (hair reduction). CO 2 laser was used for surgery with a success rate ranging from 70.7% to 96.7%. CO 2 laser is useful for surgery of stationary HS lesions, but it is difficult to draw a conclusion on the use of IPL and Nd:YAG (hair reduction) as the studies were too heterogeneous to perform a meta-analysis., Competing Interests: Declaration of Competing Interest Zealand University Hospital is a member of the European Reference Network on Rare and Undiagnosed Skin Disorders and the European Hidradenitis Suppurativa Foundation.

Hidradenitis suppurativa (HS) is a chronic, debilitating skin condition that is characterized by painful pustules, nodules, abscesses, and sinus tracts. The complicated and fast-evolving treatment of HS consists of a multi-tiered approach that includes, antibacterial, antihormonal, anti-inflammatory, and surgical options. Studies have demonstrated an earlier age of onset and increased prevalence of HS in patients with intellectual and developmental disability (IDD) compared to patients without IDD. To explore the use of an intensive multi-tiered HS management algorithm that requires monthly office visits, monthly intravenous therapy, and several daily treatment modalities in an HS population with IDD, we conducted an IRB-approved retrospective chart review of HS patients treated at the Albert Einstein College of Medicine-Montefiore HS Center (HSC) with diagnoses of concurrent IDD to investigate their demographic and diagnostic characteristics, as well as the spectrum of therapies employed in this cohort. A total of 22 HS patients with concomitant IDD, including trisomy 21, unspecified intellectual disability, autism spectrum disorder, and trisomy 13 were identified. Therapies utilized in this cohort for HS included topical and oral antibiotics, spironolactone, finasteride, oral contraceptive pills, infliximab, adalimumab, isotretinoin, intralesional and intramuscular triamcinolone injections, and excisional surgery. In conclusion, our findings indicate that despite the practical challenges, daily oral antibiotic regimens, anti-androgen combinations, oral retinoids, infliximab, adalimumab, and surgery collectively play important roles in treating HS patients with IDD. Our cases underscore the importance of utilizing the full range of modalities as the HS treatment algorithm continues to evolve., (© 2023.

Hidradenitis suppurativa (HS), a chronic disease of the apocrine bearing skin causing induration, pain, draining sinuses, and subcutaneous abscesses, significantly impairs patients' quality of life (QOL). Full-thickness excision followed by skin grafting of the involved area can be curative. Herein, we evaluated the impact of this surgical treatment on QOL and depression symptomatology. Adult patients (≥18 years) who consented to participate filled out the dermatology quality of life (DLQI) and the Patient History Questionnaire (PHQ-9) at consent and at 1, 6, and 12 months post-initial evaluation and surgery. Demographics, HS, admission, and operative information were collected. Sixteen patients were included. Subjects were mainly white (81.3 %) and female (56.3%) with a median age of 38.2 (Interquartile range: 34.2-54.5); 62.5% were obese (BMI= 39.7 [28.4-50.6]). Half of the subjects presented with HS in 2 or more areas. Six patients were still undergoing surgeries at 6 months. One-, six-, and 12-month follow-up surveys were obtained from 14, 11, and 8 subjects for DQLI and from 14, 9, and 5 subjects for PHQ9. DLQI scores significantly decreased at 6 months compared to baseline, which indicates QOL improvement (10 [4-20] vs 15.5 [12-21.8], P = .036). Although not significant, PHQ9 scores tended to decrease. For those with the worst disease, DLQI significantly decreased at both 6 (P = .049) and 12 months (P = .047) compared to baseline. Despite a small sample size, our data suggest that aggressive surgical treatment improves the QOL of HS patients. Further studies are warranted to confirm our findings., (© The Author(s) 2022.

Hidradenitis suppurativa (HS) is a painful, inflammatory skin disease that has historically been understudied in the pediatric population. Procedural interventions, such as surgical excisions, skin grafts, and lasers, are important for comprehensive HS disease management. However, there is a lack of data on procedural treatments for HS in pediatric patients. The purpose of this study was to conduct a systematic review of the literature on the efficacy and safety of procedural treatments for HS in pediatric patients. In April 2022, MEDLINE and EMBASE databases were searched for articles on the efficacy of procedural treatments for HS in patients <18 years of age. Two independent reviewers extracted data from relevant studies. From 1974 to 2021, 23 articles with 81 patients were identified. Patients' Hurley stages included stage I (9.1%, 1/11), II (36.4%, 4/11), and III (54.5%, 6/11). The most extensively studied procedural interventions include negative pressure wound therapy (n = 30), surgical excision with skin graft/flap (n = 19), and endoscopic electrode or laser treatment (n = 11). In all, promising response rates for procedural management strategies were observed in the literature but the findings were largely based on case reports/series. Randomized controlled trials (RCTs), especially those geared toward minimally invasive procedural treatments, are needed to help guide clinicians on the most efficacious treatment modalities for pediatric patients with HS., (© 2023 The Authors.

The loss of efficacy of adalimumab, one of the most commonly used biologics for the treatment of hidradenitis suppurativa/acne inversa, is not news to the scientific community, and it should be noted that the number of cases not responding to this agent has been progressively increasing in recent years. We present a 45-year-old patient with hidradenitis suppurativa/acne inversa (Hurley II-III) with a complaint duration of 3 years who has been on adalimumab 40 mg weekly for 9 months. The lack of improvement in the clinical condition as well as the progression of the disease within the ongoing biologic therapy led to the need for repeated hospitalizations and the additional introduction of intravenous treatment with a regimen of antibiotics (Ertapenem, Metronizadol, Ceftriaxone), zinc, colchicine, and pain relievers. During these hospitalizations, a partial improvement was found, which was not durable and required the parallel administration of antibiotics, colchicine and zinc in combination with adalimumab in an outpatient regimen. Several attempts at surgical treatment/incision in non-specialized units were also made, and these too remained generally unsuccessful or with a nondurable, unsatisfactory clinical outcome. Due to the subsequent consecutive worsening of the symptomatology, the patient was admitted for evaluation of the clinical condition and optimization of treatment. Surgical treatment was performed by surgical deroofing under general anaesthesia, concurrent with discontinuation of adalimumab/antibiotic application and long-term remission was achieved. Surgical deroofing has also been shown to be an effective therapeutic option in the loss/lack of efficacy of adalimumab in patients with hidradenitis suppurativa (Hurley II-III). In the case of therapeutic resistance or worsening of symptomatology in patients with acne inversa within adalimumab therapy, other advanced alternatives such as golimumab, anakinra, etanercept are available. The efficacy of these second-line agents is also questionable due to the development of resistance to them as well, which in turn necessitates the frequent switch to third-line agents such as: Ustekinumab, Tildarkizumab, Certolizumab or Ixekizumab. The future will show to what extent this "trust" could be justified and whether in practice the surgical approach will once again displace the so-called "modern options" as the reasonable next basic and reliable alternative. The disadvantage of modern biological therapy is mainly due to the loss of efficacy/development of resistance over time, multiple side effects and frequent recurrence after discontinuation of treatment. In contrast, in the case of specific, stage-oriented, specialized surgical treatment of hidradenitis suppurativa/ acne inversa, in the form of surgical deroofing, for example, the results are long-lasting and in the case of recurrences: the latter are much more easily managed by dermatosurgery/surgery again. The effect achieved after this type of manipulation is essential for the patients' quality of life and guarantees to a large extent also prevention of the development of keratinocyte tumours in the areas affected by chronic inflammation. Precisely because of the aforementioned facts, in a serious number of patients this type of treatment could be considered as a priority. The rethinking of the guideline and the staging of surgical modalities as first-line therapy could, in a serious number of patients, have a positive effect. Swap for surgery seems to be a good alternative.

There is a lack of studies assessing whether wide excision surgery in hidradenitis suppurativa affected areas is useful for the global control of the hidradenitis suppurativa. We aimed to find whether surgery results were a better global control on the disease activity in both, the area where the surgery is performed and distant areas. We evaluated the disease course of 17 patients with hidradenitis suppurativa who underwent wide excision of complex fistula tracts between October 2018 and January 2022 at the Hospital Universitario de la Princesa, Madrid. We found that wide excision of complex fistulas produces an overall positive effect on the inflammatory activity in hidradenitis suppurativa that may be important to achieve an adequate control of the disease., (Copyright © 2023 AEDV.
