Pilonidal sinus is a disease with a great economic significance. Between 1941 and 1945 for instance, 78.924 soldiers (equivalent to 5 infantry divisions!) were admitted for this disease in the U.S. Army hospitals (Casberg 1949). Hardaway (1956) has estimated this to have cost more than 100 million dollars. In the Netherlands the estimated number of adrnmssions for pilonidal sinus in 1967 was 2.984 in a total of more than 1.000.000 admissions. The average duration of hospitalízadon was 18 days (Fokkens , 1969). In this thesis the gratifying results of a simple, ambulatory treatment are described, which spares the patient unpleasant clinical admission. In addition, the ambulatory treatment has a great advantage of not using precious hospital beds.
