Repair of a sliding (type I) hiatal hernia in a cat via herniorrhaphy, esophagoplasty and floppy Nissen fundoplication

Abstract

Case summary A 10-month-old domestic shorthair cat was evaluated for severe esophagitis and protracted vomiting and regurgitation secondary to a sliding (type I) hiatal hernia. The hernia and concurrent upper airway obstruction (nasopharyngeal polyp) were diagnosed with a multi-modality approach, including thoracic and abdominal radiographs, abdominal ultrasound, computed tomography and endoscopy. Following unsuccessful attempts at medical management, lower esophageal incompetence was successfully treated by employing a combination of surgical techniques, including herniorrhaphy, esophagopexy and modified (floppy) Nissen fundoplication. Relevance and novel information A multi-modality imaging approach was valuable in completely assessing the extent of this cat’s disease. Although an untraditional approach, the authors report herein the first clinical description of the use of combined surgical techniques with the floppy Nissen fundoplication technique (an antireflux procedure) in a cat. This procedure was used as a first-line surgical technique in this cat with severe lower esophageal incompetence, and may be a viable option for cases non-responsive to other therapeutic interventions. Further investigation of this surgical technique is warranted.
