A hairy cavity: endoscopic therapy of a presacral recurrence of a complex pilonidal sinus

Recently, minimally invasive techniques to avoid radical excisions of the pilonidal sinus with long-lasting secondary wound healing were developed. We describe a rare case of an intrapelvic, pararectal recurrence of a pilonidal sinus, who was innovatively treated with flexible endoscopy. A 43-year-old Caucasian man presented with an intrapelvic, pararectal recurrence of a primarily wide-stretched pilonidal sinus, originally located in the...
