[Therapy of the pilonidal sinus--Primary wound closure or open wound after excision]

Abstract

The postoperative follow up of 177 operations in 162 patients with pilonidal sinus was investigated. After excision of the sinus a primary wound closure was performed in 80 cases; in 83 cases the wound was left open. After primary wound closure 40 % of the patients showed a primary healing of the wound. Although the remaining 60 % of the wounds healed secondarily the patients were not disabled longer and did not demonstrate more frequently recurrences than those with open wound management. As a consequence we recommend a primary wound closure after excision of a pilonidal sinus.
