[Surgical treatment of hidradenitis suppurativa: a retrospective study of 93 cases].

INTRODUCTION: Hidradenitis suppurativa is a chronic disease, severe forms of which may be highly invalidating. Although wide surgery is usually considered the most effective curative therapy, few medical teams in France have extensive experience of this approach. Our aim was to evaluate the clinical history and the results of surgery in all patients operated with curative intent in an experienced centre.

PATIENTS AND METHODS: Medical records were reviewed for all patients operated between January 1985 and January 2007. In addition, the patients were contacted by telephone and/or letter and asked about their clinical history, the repercussions of their disease on their daily lives, postsurgical relapse and their overall satisfaction regarding surgery. Separate analyses were carried out for patients and for individual operated sites.

RESULTS: Of 93 patients followed-up for between one and 205 months (mean: 30 months), 209 anatomical sites were operated with curative intent, using either limited excision (i.e. including all visible lesions without margins) or wide excision (i.e. including all lesions with a significant margin). The disease had been present for an average of 7.6 years before surgical treatment, with onset seven years earlier in women. Most patients had previously received multiple and often unsuitable medical treatments. Patients' personal and professional lives were highly affected. Surgery required hospitalization for an average duration of 6.6 days, caused complications in 21% of cases and was often perceived as trying. Relapse in the operated areas occurred in 33% of cases and this was more frequent after limited excision. Nevertheless, 74% of patients were ultimately satisfied with their surgical treatment and most regarded surgery as the only really effective therapy.

DISCUSSION: Our study confirms the heavy repercussions of hidradenitis suppurativa on patients' day-life as well as the value of surgical management by experienced surgeons.

CONCLUSION: Wide excision remains the mainstay of therapy in extensive forms of hidradenitis suppurativa. However, this chronic, disseminated and recurrent disease continues to be insufficiently understood and innovative medical approaches, including the development of clinical trials, are required.
