Case Report

The Use of a Cutting Balloon for Dilation of a Fibrous Esophageal Stricture in a Cat

Figure 2

Endoscopic appearance of the esophageal stricture at re-examination on day 53 after 4 previous dilations. A band of fibrous tissue is present at the site of stricture extending from 7 o’clock to 2 o’clock resulting in a lumen diameter of 4 mm (a). After initial dilation with an 8 mm cutting balloon, multiple defects (white arrowheads) are noted in the fibrous band, now at 3 o’clock to 9 o’clock (b). Subsequent serial dilations with conventional dilation balloons resulted in further disruption of the fibrous band at these defects (c) and more diffuse mucosal tearing resulting in a lumen diameter of 10 mm (d).
