Objective—To determine outcome of bougienage for treatment of benign esophageal stricture (BES) in dogs and cats and identify risk factors for the condition.

Design—Retrospective case series.

Animals—20 dogs and 8 cats with BES.

Procedures—Medical records were reviewed for information on signalment, clinical features, and outcome. Long-term outcome information was obtained with a questionnaire.

Results—Esophageal bougienage was performed with dilators ranging from 5 to 15 mm in diameter; median numbers of bougienage procedures were 3 (dogs) and 4.5 (cats). A good outcome, defined as tolerance of solid food with regurgitation less than once a week, was achieved in 14 dogs and 6 cats. Complications were minimal, with nonfatal esophageal perforation occurring in 1 cat. Four dogs and 1 cat were euthanized or died because of esophageal disease. Dogs with BES were more likely to be female, have a recent history of general anesthesia, have received an antimicrobial orally, or have a history of vomiting than were dogs in a reference population. Cats with BES were more likely to have a recent history of general anesthesia, vomiting, or gastrointestinal tract trichobezoars than were cats in a reference population. Doxycycline-induced esophagitis was the suspected cause of BES in 3 cats. Although general anesthesia was associated with development of BES in 18 dogs and 5 cats, concurrent potential causes of esophageal injury were common.

Conclusions and Clinical Relevance—Results suggested that esophageal bougienage was a safe and effective treatment for most dogs and cats with BES, with outcomes similar to those reported for balloon dilation.
