OBJECTIVE: To examine the role of conservative, nonexcisional methods in the treatment of pilonidal sinus disease. DESIGN: Pilot nonrandomized cohort study and follow-up retrospective study. SETTING AND PATIENTS: In the pilot study, all patients treated for pilonidal sinus disease consecutively over 3 years at an Army community hospital, and in the follow-up study within a closed federal population, all patients admitted with a diagnosis of pilonidal sinus disease over 17 years to an Army medical center. INTERVENTIONS:Conservative, nonexcisional therapy (meticulous hair control by natal cleft shaving, improved perineal hygiene, and limited lateral incision and drainage for abscess) with initial comparison to excisional procedures. MAIN OUTCOME MEASURES: Occupied-bed days for conservative vs excisional therapy during a 3-year pilot study and the number of admissions and procedures performed for pilonidal sinus disease at an institution dedicated to conservative treatment alone. RESULTS:Complete healing over 83 occupied-bed days was demonstrated in 101 consecutive cases managed during 1 year with the conservative method, whereas slower healing over 4760 occupied-bed days was observed in 229 patients undergoing 240 operative procedures during the preceding 2 years. With application of conservative treatment over 17 years, only 23 excisional operations were performed. CONCLUSIONS:Conservative therapy effectively controls pilonidal sinus disease in the nonoperative outpatient setting while promoting near-normal work status and is preferred over excisional operations.
