title: Using negative pressure wound therapy following surgery for complex pilonidal disease: a case series.
abstract: Complex pilonidal disease, an uncommon manifestation of an anorectal condition, is characterized by chronic or recurrent abscesses with extensive, branching sinus tracts. Definitive treatment requires wide excision of all involved tissue followed by secondary intention healing or reconstructive surgery. All treatment options have unique advantages and disadvantages. Following recent reports that negative pressure wound therapy after surgery for complex pilonidal disease may be a useful alternative to moist saline dressing treatments, five patients (three men and two women, median age 21 years [range: 16 to 63 years]) with complex pilonidal disease (symptom duration range 6 months to 30 years) were treated on an outpatient basis. Following wide excision under general anesthesia, a portable negative pressure wound therapy device was applied. Mean wound defect size after excision was 11 cm x 4 cm x 5 cm, or 205 cm(3) (range 90 cm(3) to 410 cm(3)). Negative pressure wound therapy was used for an average of 6 weeks (range 4 to 9 weeks) and mean time to complete epithelialization was 12 weeks (range 9 to 22 weeks), including use of moist saline dressings post negative pressure wound therapy. Treatment was discontinued in one patient due to skin irritation. No other complications were observed. Long-term follow-up is required to assess the risk of recurrent pilonidal disease or wound failure following negative pressure wound therapy. Additional studies of negative pressure wound therapy in the management of pilonidal disease are warranted.
