In pilonidal disease, the surgical plan depends on how complex the disease is. When there is a complicated pilonidal cyst with sinus tracts and an associated abscess, the treatment is wide excision of the cyst and all sinus tracts, followed by marsupialization of the wound. Excision removes the diseased tissue and sinus network, while marsupialization sutures the wound edges to the underlying tissue to keep the wound open and allow healing by secondary intention, reducing dead space and helping tract closure. This approach matches a case described as a complicated pilonidal cyst with sinus abscess, which is more extensive than a simple drainage procedure. The other options—the incision and drainage of a pilonidal abscess, routine hernia repair, or laparoscopic cholecystectomy—do not address the pilonidal disease in its complicated form or are entirely unrelated to pilonidal pathology.
