INTRODUCTION

Hidradenitis Suppurativa (HS), also known as acne inversa, is a chronic inflammatory condition that affects millions worldwide.1,2 HS is characterised by the development of painful nodules, abscesses and sinus tracts which can become infected and purulent.

Excruciating pain, reduction in range of motion (ROM) and issues with mental health and self-esteem are reported as significant, and detrimental to patient quality-of-life (QoL).3 The severity of HS is most often measured using the Hurley staging system, ranging from I-III. Stage I is characterised by the presence of abscesses without any sinus tracts or scarring. Stage II involves multiple abscesses or sinus tracts existing in a single area. In stage III, sinus tracts and scarring are interconnected, and multiple abscesses occur in the region.1 Figure 1 describes the different stages of the Hurley staging system.

(a) Hurley stage I HS with one or possibly two solitary nodules. (b) Hurley stage II HS with multiple abscesses. (c) Hurley stage III HS with diffuse and connected abscesses, sinus tracts and cicatrization.

For mild HS, management is typically conservative in nature, involving topical antiseptic wash or topical antibiotics such as 0.1% clindamycin.4 Other options for mild to moderate HS are the use of long course oral antibiotics, or in severe cases, treatment with biological agents such as tumour necrosis factor (TNF) inhibitors adalimumab or infliximab.5

Surgery is indicated when HS is not medically responsive and is considered the only definitive treatment for recurrent abscesses and sinus tracts associated with stage II-III HS.6 Currently there are a wide range of approaches available, however, there is no consensus on the timing and type of surgery that should be performed. As such, this review aims to critically evaluate the surgical methods of treating HS and their outcomes, as reported in the literature.

METHODS

The Ovid Medline and PubMed databases were used to search for relevant literature. Manuscripts with type I-V7 evidence were included. The search phrases used for both databases were as follows:

– (Acne inversa OR hidradenitis suppurativa) AND (surgery OR surgical) AND (management OR treatment) with the following filters applied: Last 10-years, Full text available in English.

Inclusion Criteria

1. The full text was available in English.
2. The literature was published in the last 10 years (2012- current).
3. The article was relevant to the surgical treatment of hidradenitis suppurativa with a surgical treatment defined as “the use of instrumentation or manual methods to make an incision or remove body tissues in the treatment of a pathological process”.
4. The primary outcome of “recurrence of HS after surgery” was reported.

Secondary outcomes assessed in included articles were: surgical complications, restriction in ROM post-surgery and QoL changes post-surgery.

Exclusion Criteria

– The article did not report whether recurrence occurred post-surgery.
– The recurrence rate was not linked to a defined surgery method.
– The article was a review.

RESULTS

The search yielded 326 results, 33 duplicates were removed, and 293 articles underwent title and abstract screening. The title and the abstract were assessed using the inclusion and exclusion criteria and 145 articles were sought for a full text review. Two articles could not be retrieved in English and thus only 143 articles were analysed in the full text review. During the full text review articles were read in full and assessed against the exclusion and inclusion criteria. At the end of this process 48 articles were included in the review. Figure 2 summarises the search.

Incision and Drainage/Deroofing

Procedures Incision and drainage (I&D) is typically used in more acute disease lesions either when only abscesses or nodules exist, such as Hurley Stage I disease. After thorough washout of the cavity, the wound is packed with dressings and allowed to heal secondarily.

Deroofing is a procedure in which a superficial portion of a nodule or sinus tract is excised, leaving the floor of the tract or nodule to allow for more rapid re-epithelisation with the wound left to heal by secondary intention. A skin tissue sparing excision and electrosurgical peeling (STEEP) technique is a type of deroofing whereby a HS lesion is removed in a layer-by-layer fashion until the floor of the tracts is left. Table 1 outlines the articles that performed I&D and deroofing procedures included in this review.

Surgical Excision

Surgical excision, either wide or radical, was the most reported surgical treatment. It was typically offered for Hurley Stage II or III disease. The wound was either allowed to heal by secondary intention (SIH), primarily closed, or reconstructed with a skin graft or flap. Wide excision typically detailed excision down to healthy tissue whereas radical excision typically referred to excision down to muscle fascia. Table 2 summarises the studies that used primary closure or healing by secondary intention following excision of HS.

Multiple tissue flaps have been described to reconstruct various defects. The flaps used were all variations of perforator flaps with different characteristics such as donor site and advancement method. In perforator flap reconstruction, perforator vessels are left intact as the flap is moved to its new location creating a “pedicle” that connects the donor site with reconstruction site that the flap has been moved to. This type of reconstruction is beneficial in HS cases as it allows for areas with wide defects to be reconstructed. Table 4 summarises the articles reporting flap use as part of the surgical management of HS.

Novel Techniques

Three novel techniques were identified in the literature search. These techniques involved removing diseased tissue using CO2 lasers using a layer-by-layer approach like the STEEP procedure. Table 5 summaries the articles using novel techniques.

DISCUSSION

There was no standardised treatment protocol for HS. Less invasive methods such as incision and drainage were offered for early HS (Hurley stage I) and were sometimes paired with the use of hydrogen peroxide or cryo insufflation with liquid nitrogen. These methods aimed to optimise healing by removing the bacterial load in the area. These treatments were effective in reducing pain and discomfort associated with HS lesions. However, they were also associated with a moderate rate of recurrence (19-30%). It should be noted that there was a small number of articles that reported I&D procedures and as such the recurrence rates are most likely not indicative of all I&D patients.

Deroofing procedures reported recurrence rates of 0 to 30% with the most common complication being post-surgical hyper-granulation.9,10 Recurrence in these procedures is thought to be related to unexcised diseased follicles that were either deep to the margins of the deroofing or from sinuses that were not completely deroofed9 or from previously normal follicles that have progressed to become diseased after the procedure. The success of deroofing procedures is heavily determined by the ability of the surgeon to identify and deroof all lesions in the area or patient factors such as the severity of HS or complexity of sinus networks. Deroofing appears to be a viable option for patients not suited to or not willing to undergo larger procedures, however, there have not been any large cohort studies examining efficacy, nor have there been any trials comparing it to other surgical methods.

Surgical Excision

Management after excision was varied. Primary closure and healing by second intention were associated with shorter operating time and required less follow-up monitoring, but were associated with high rates of recurrence, with rates between 18% and 75% in larger cohort studies (n>30). The reported complication rates varied significantly between the articles that examined methods using excision and repair with primary closure or healing by second intention. However, the most frequently reported complications were wound infections and post-operative pain.12,16,1822,24 Some proposed reasons for this were that secondary intention healing and primary closure were typically suited to smaller wounds. Limited excision is likely to leave some diseased follicles behind and thus leave a seed for recurrence. However, this has not been proven.

Most of the patients who underwent secondary intention healing or primary closure had HS of Hurley stage I-II and this may be because primary closure (PC) and SIH may not be possible for wide and deep wounds. More severe Hurley stage II or Hurley stage III HS typically encompass wider areas and have tracts extending deeper into the dermis or adipose tissue of the area and the large wounds left from complete excision of diseased tissue would be difficult to close using PC and may lead to significant restrictions in ROM. Wide excision with SIH or primary closure is most suited to less severe HS or smaller disease areas in regions that are easier to access or where ROM impairment is not as big of a factor.

Skin Grafts

Skin grafts were a commonly reported method of wound closure after wide or radical excision of HS. There were two main methods of skin grafting, immediate or delayed. In some delayed grafting methods, adjunct treatments such as vacuum dressing assisted NPWT, or dermal matrices, were used to aid granulation tissue formation and vascularisation of said tissue before grafting. The aim of this was to improve ROM and aesthetic outcomes by reducing scar contracture. These adjuncts were commonly used in axillary cases of HS where ROM impairment significantly impairs QoL.24,26,36

Most articles examined reported no recurrence of HS post excision and skin graft, however Ovadja et al21 and Mendes et al19 reported recurrence rates of 63% and 50% with samples sizes of 11 and 2 respectively. Similarly, to deroofing procedures, it is postured that local recurrence stems from incomplete removal of diseased follicles or from progression of healthy follicles to a diseased state. The most common complication was wound dehiscence, but the rates were highly varied between papers. Overall, skin grafting, especially when used after surgical excision was reported to be an effective treatment for HS with low recurrence and good outcomes functionally (low ROM restriction) and aesthetically, while being appropriate for HS of large areas. Thus, suggesting that these methods could be applied to HS of high severity in most areas of the body. It is noted however that delayed skin grafting with adjuvants requires a high-level of patient adherence, as these methods involve regular wound dressing management or temporary movement restricting braces such as 90-degree abduction shoulder braces to optimise the NWPT or extracellular matrix (ECM) adjuncts. As such, optimal treatment results require discussion on these points to be held before treatment is commenced.

Flap Reconstruction

The aim of using flaps was to allow for large areas of radical excision to excise as much diseased tissue as possible, while having a method of reconstruction that would be able to close the site and allow for good functional outcomes. Flaps help achieve this goal as having their own blood supply, flaps can be used to cover large areas while also being unlikely to exhibit any contraction and thus are unlikely to impair ROM in the long-term.57

The use of flaps does pose some challenges. Procedures involving flaps take significantly longer than other options such as skin grafting and are often more complicated with considerations for the flap donor site, flap blood supply, flap advancement and long-term flap monitoring, needing to be made. Within this study, flaps were typically reported to be used for cases of axillary HS or gluteal/groin HS where the lesion area was large. The flaps used were local or perforator flaps with no free flaps being reported. Recurrence rates were generally low with the majority of articles reporting rates between 0% and 7%, however, a small number of articles reported higher recurrence rates of 18%-53% with moderate patient sample sizes (n=25 to n=100). Complication rates varied with reports ranging from no complications to 42% complication rates post-surgery. Of the reported complications, wound dehiscence and minor flap necrosis were the most reported and highlight the complexities of constructing flaps with adequate blood supply and underlining the need for long-term surveillance of the flap. Positive functional outcomes were widely reported especially in axillary cases of HS. Shoulder ROM was reported to range between 160° of abduction and full ROM post-surgery and the reporting of contracture was rare, occurring along scar lines along the flap’s border in some cases but did not significantly hinder ROM. Overall flap reconstruction was effective at preserving ROM and covering areas of wide excision like those found in the treatment of severe HS. Of note however, is the increase in complexity in surgery and treatment follow-up when using flaps.

Novel Techniques

The novel techniques identified revolved around laser ablation or removal of diseased tissue. Hazen et al55 and Mikkelsen et al56 examined the use of CO2 laser to ablate diseased tissue while Abdel Azim et al54 examined CO2 laser ablation and Nd:YAG laser treatments. Nd:YAG lasers work by emitting a wavelength or radiation that is highly absorbed by hair follicles and thus theoretically destroys or partially cauterises the follicle. Recurrence rate varied, ranging from 0 to 45% with CO2 laser treatment, while Nd:YAG monotherapy was reported to have a 80% recurrence rate. A positive characteristic of laser ablation is that the ablation of tissue also provides a haemostatic effect like electrocautery which could be beneficial during treatment of wide areas or areas with a higher bleeding risk.

LIMITATIONS

There were several factors that prevented quantitative comparison between articles reporting different surgical treatment methods. Reporting of outcomes was incredibly varied. There was no standard follow-up time, no standard set of reported outcomes and recurrence rate was often variable even when comparing articles examining similar procedures. Ununiform reporting was further compounded by the heterogenous nature of HS with differing disease morphology and patient co-morbidities making each case slightly different and not directly comparable to other patients. The inclusion of all articles with evidence levels of type I-V meant that novel and small sample size procedures could be assessed and discussed but also meant that quantitative comparisons would not be reliable. Comparisons between QoL improvement could not be made as this was not widely reported and a common scale for assessing this was not adopted between studies.

CONCLUSION

Surgical management is an effective treatment for HS. It has the potential to be curative even in severe cases of HS. Factors such as surgeon preference, disease severity and patient goals influence what treatment is offered. Despite this, most methods share the same principle of excision of as much diseased tissue as possible. For Hurley Stage I lesions, incision and drainage is the less invasive option that is effective in managing symptoms such as pain. For Hurley Stage II-III lesions, wide excision with reconstruction seems to be a curative option that preserves function of the affected area. However, there are currently no randomised control trials comparing different methods and this is likely due to the heterogenicity of disease morphology and lack of defined treatment algorithm.
