Prospective evaluation of an indwelling esophageal balloon dilatation feeding tube for treatment of benign esophageal strictures in dogs and cats.

BACKGROUND: Despite multiple dilatation procedures, benign esophageal strictures (BES) remain a recurring cause of morbidity and mortality in dogs and cats. OBJECTIVE: Investigate the use of an indwelling Balloon Dilatation esophagostomy tube (B-Tube) for treatment of BES in dogs and cats. ANIMALS: Nine dogs and 3 cats. METHODS: Animals with BES were recruited for our prospective study. Endoscopic and fluoroscopic evaluation of the esophagus and balloon dilatation were performed under general anesthesia, followed by placement of an indwelling B-Tube. The animals' owners performed twice daily at-home inflations for approximately 6 weeks. Repeat endoscopy was performed before B-Tube removal. Animals were reevaluated for changes in modified dysphagia score (MDS) after B-Tube removal. RESULTS: The B-Tube management was relatively well tolerated and effective in maintaining dilatation of a BES while in place. These animals underwent a median of 2 anesthetic episodes and were monitored for a median of 472 days (range, 358-1736 days). The mean MDS before treatment was 3.1 ± 0.5/4.0 and final follow-up MDS were significantly (P < .0001) improved at 0.36 ± 0.65/4.0. Eleven of 12 animals (91.7%) had improved MDS at the end of the follow-up period, with 8/12 (66.7%) having an MDS of 0/4, 2/12 (16.7%) an MDS of 1/4, and 1/12 (8.3%) an MDS of 2/4. One dog died. CONCLUSIONS AND CLINICAL IMPORTANCE: The B-Tube offers an effective, and more economical method, and often decreased anesthetic time to repeated balloon dilatation procedures for the treatment of BES in dogs and cats.

Traumatic fracture of the medial coronoid process in 24 dogs.

OBJECTIVE: To describe traumatic fracture of the medial coronoid process in dogs as a clinically distinct disease unrelated to congenital elbow dysplasia. METHODS: Clinical records of dogs with acute, traumatic, unilateral lameness attributable to medial coronoid process disease were reviewed retrospectively. Clinical interpretation included findings on physical examination, orthopaedic examination, and subjective gait analysis. Radiographs of the affected and contralateral elbows were obtained and reviewed for pathology. Arthroscopy of the elbow joints was performed by one of three surgeons and findings were compared to preoperative diagnostics. Postoperative follow-up was continued for 16 weeks. RESULTS: Twenty-four dogs were included in this study. All dogs in this study were free of radiographic evidence of medial coronoid pathology. All dogs were diagnosed with a single, large, displaced or non-displaced fracture of the medial coronoid process, with no other joint pathology. Dogs generally had an excellent short-term outcome following arthroscopic treatment of the fractured medial coronoid process. CLINICAL SIGNIFICANCE: Traumatic fracture of the medial coronoid process should be considered a clinical disease distinct from dysplasia-related fragmentation and should be considered as a differential diagnosis in dogs that are presented with the complaint of acute unilateral elbow discomfort or lameness, especially after concussive activities involving the forelimb. .
