Epidural abscess complicating Swenson procedure: a case report and a review of the literature.

A case is reported in which an anastomotic leak following the Swenson procedure for Hirschsprung's disease was complicated by the development of a pelvic abscess that communicated freely with the epidural space. The child presented with signs and symptoms of an epidural abscess, but his myelogram was normal. The diagnosis was made by urografin enema. The child was treated by defunctioning colostomy and drainage of the pelvic abscess by enlarging the defect at the anastomosis site digitally. The epidural space drained freely to the pelvis and therefore laminectomy was not required. The possible etiology of such a communication is discussed.
