About

A staging system was defined based on morphological extent of disease (stage I to stage IV for primary disease, and stage R for recurrent disease). Specific surgical technique was used for each stage. Demographics, perioperative data, short-term and long-term outcomes were evaluated according to the disease stage.

Full description

The collected data of patients who underwent surgery for the treatment of pilonidal sinus disease prior to June 2011 were analyzed. Following this analysis, a staging system was defined based on morphological extent of disease (stage I to stage IV for primary disease, and stage R for recurrent disease). Specific surgical technique was used for each stage. "Pit-picking" technique was performed under local anesthesia on an outpatient basis in stage I and stage IIa patients. For stage IIb and stage III patients, the Bascom Cleft Lift /modified Bascom Cleft Lift techniques were performed. For stage IV patients, the rhomboid excision with the Limberg flap technique was used. Demographics, perioperative data, short-term and long-term outcomes were evaluated according to the disease stage.
