RESUMO
BACKGROUND: Pilonidal sinus disease (PNS) is not uncommon in children. Controversy remains over the best treatment and there is limited evidence. This systematic review and meta-analysis aims to establish which techniques have the best outcomes in children. METHODS: MEDLINE, EMBASE and CENTRAL databases were searched. Studies reporting treatment outcomes for PNS in children were included. RESULTS: Open healing has pooled risk of recurrence of 26% (95%CI 15-38%), risk of wound complication of 21% (9-36%) and wound healing ranged from 38-92 days. Midline primary closure has pooled risk of recurrence of 12% (8-18%), risk of wound complication of 30% (19-46%) and wound healing ranged from 8 to 32 days. Off-midline primary closure has pooled risk of recurrence of 6% (1-15%), risk of wound complication of 14% (6-25%) and wound healing was 27 days. VAC therapy has pooled risk of recurrence of 20% (0-65%) and wound healing ranged from 38 to 92 days. Minimally invasive techniques has pooled risk of recurrence of 7% (1-16%) and wound healing ranged from 21-30 days. Marsupialisation has pooled risk of recurrence of 6% (0-22%), and wound healing ranged from 6 to 41 days. CONCLUSION: Evidence for management of PNS in children is poor. Off-midline primary closure, minimally invasive techniques, and marsupialisation have the best outcomes. LEVEL OF EVIDENCE RATING: IV.
