Per anal balloon dilatation of a post-necrotizing enterocolitis stricture of the sigmoid colon.

Per anal balloon dilatation of a sigmoid colon stricture caused by necrotizing enterocolitis allowed identification of a more proximal lesion which would otherwise have gone radiographically undetected. Repeated dilatations at two weeks and four weeks following the initial dilatation of the stricture resulted in relief of the stricture and obviated the need for surgical treatment of this lesion.
