Anal stenosis with megarectum: an unusual complication of a perineal burn.

A case of a 3-year-old boy with anal stricture and megarectum is described. Overflow incontinence and soiling were corrected by local flaps and skin graft and were maintained by frequent dilatations after downward traction of the whole anus was performed. The options of immediate and late treatment of such burns and the colostomy procedure are discussed.
