Background:

There is an ongoing debate regarding the optimal surgical management for pilonidal disease in the pediatric population. The purpose of this study was to evaluate a pediatric surgeon’s experience at a Canadian children’s hospital over 35 years.

Methods:

We performed a retrospective review of the charts of patients seen and treated from July 1969 to December 2003, inclusive. All patients were evaluated for age, sex, clinical diagnosis, infection, treatment, healing time, complications and results.

Results:

In all, 121 adolescents with pilonidal disease (64 boys, 57 girls) with a mean age of 15 (range 12–19) years were evaluated at the same children’s hospital. The 107 (88%) patients with infection (46% acute) underwent surgery. At operation, all 107 pilonidal cysts were either excised and packed open, marsupialized or excised and closed primarily without drainage under general anesthesia; the operation performed was arbitrarily chosen. Vacuum-assisted closure was not used. All patients received antibiotics. The time for healing after the initial operation in the group whose cysts were excised and packed open was at least twice as long (75 d) as in the other 2 groups (p = 0.031). Disease recurred in 24 (22%) patients, 6 (25%) of whom experienced 2 recurrences. Among the 90 patients in the excised and packed open group, 20 (22%) experienced recurrences and 5 (25%) experienced 2 recurrences. Among the 13 patients in the marsupialized group, 3 (23%) experienced recurrences and 1 (33%) experienced 2 recurrences. Among the 4 patients in the excised and closed primarily without drainage group, 1 (25%) experienced a recurrence and none experienced 2 recurrences (p = 0.12). Each recurrence was smaller than the original. All wounds eventually healed. There were no other complications and no deaths. A multivariable logistic regression analysis revealed that the type of surgical approach was not predictive of recurrence after controlling for age and sex.

Conclusion:

Age, sex and surgical approach were not predictive of recurrence. From our experience, excision and packing open the wound produced a longer morbidity but offered the same results compared with marsupialization or excision and primary closure without drainage.
