Abstract

Abstract : Objectives: Acquired oesophageal strictures remain challenging to manage in canine and feline patients. The aims of this study were to describe the treatment, complications, short‐term outcome and long‐term follow‐up of benign oesophageal strictures treated by balloon dilatation or stenting in dogs and cats and to describe adjunctive techniques to minimise the complication rate of stent placement. Materials and Methods: Retrospective analysis of medical records of dogs and cats with benign oesophageal stricture diagnosed under endoscopy between 2002 and 2019. Results: Eighteen dogs and nine cats were included, representing 39 strictures. Balloon dilatation was used as first‐line therapy, with a good outcome in 59% of cases. Stents were placed in eight cases due to stricture recurrence; 88% had a long‐term satisfactory outcome. Short‐term complications occurred in six of eight cases; migration and aberrant mucosal reaction were uncommon. In three cases, progressive mesh cutting during follow‐up reduced discomfort and trichobezoars formation and improved long‐term stent tolerance. Overall median survival time was 730 days. Clinical Significance: Long‐term prognosis of balloon dilatation as a first‐line therapy for esophageal strictures and of stenting as a rescue therapy was considered satisfactory. Although discomfort associated with stenting was frequent, tolerability might be improved by per‐endoscopic adjunctive techniques.
