Abstract
Pilonidal sinus is not a rare disease for Japanese, though it more oftenly occurred in European people. We had experienced 4 cases of the disease one after another, and successfully treated the 2 cases of them with excision and W-plasty closure. The patients included 3 males and one female aged from 23 to 39 years. A 26-year-old male underwent simple excision and suture, however, 2 times of operations were needed for healing of the wound. Thus, the rest 3 patients were treated with Z- or W-plasty closure. These surgical procedures prevent an entering of fistula due to rotating movement of crena ani which causes pilonidal sinus, namely, these methods fundamentally remove the cause of the disease. Especially, W-plasty closure, when compared to Z-plasty, appears to be more rational in easy suture after excision.
