VetBooks.ir Diseases and Disorders

15-mm outer diameter esophageal/pyloric balloon (CRE wire-guided balloon [Boston

40-mm outer diameter rectosigmoid dilator balloon (bottom).

ESOPHAGEAL STRICTURE Digital images obtained during esophagoscopy. A, A stricture site is apparent in the
center of the image. Very little material (except small amounts of liquids) could pass through this opening. B, Placement
of a balloon in the stricture site. Balloon is partially inflated and momentarily will be fully inflated to stretch/break
the fibrous stricture or cicatrix. C, Esophageal stricture after balloon dilation. Note bleeding at the site, but the lumen
diameter is markedly enlarged. Goal is to minimize the degree of inflammation secondary to ballooning to help avoid
stricture redevelopment after ballooning.
