Surgical repair of an oesophageal stricture and prestenotic dilatation in a horse.

The research discusses a successful surgical repair of an oesophageal stricture and prestenotic dilatation in a horse, that had previously experienced trauma and recurrent obstructions in the oesophagus. Despite conservative treatments having failed, surgical intervention managed to restore the horse’s condition, with no obstructions recurring in over a year following the surgery.

Diagnosis of the Horse’s Condition

• The paper presents a case of a horse diagnosed with prestenotic oesophageal dilatation and stricture. The horse had a history of trauma in the cervical area and recurrent oesophageal obstruction.
• The diagnosis was established following a clinical examination, endoscopy, and a positive contrast oesophagography test.
• Despite attempts at conservative treatment, the measures did not successfully resolve the horse’s condition, necessitating surgical intervention.

Surgical Procedure and Results

• An oesophageal myectomy, combined with myoplasty, was performed to simultaneously address the dilatation and stricture.
• Following the surgery, the horse was found to be free of any abnormalities eight weeks post-operation.
• Furthermore, the horse returned to a normal diet, and critical to its wellbeing, there was no recurrence of oesophageal obstruction in the subsequent 14 months post-surgery.

Significance of the Study

• This study notes the effectiveness of surgical intervention in treating prestenotic oesophageal dilatation and strictures in horses, particularly in cases where conservative treatment options have failed.
• The surgical techniques employed in this study – oesophageal myectomy and myoplasty – demonstrated a successful outcome in eliminating the horse’s oesophageal obstruction, with no recurrence seen within a fourteen months postoperative period.
• These findings could thereby have significant implications for tackling similar cases in veterinary medicine, potentially serving as a guide for successful surgical treatment.
