Radiographic diagnosis--gastroesophageal intussusception in a cat

Intermittent Gastroesophageal Intussusception in a Kitten Resolved with a Percutaneous Gastropexy

Gastroesophageal intussusception is a rare pathology characterized by an acute or intermittent invagination of the stomach into the lumen caudal to the thoracic esophagus, the pathogenesis is not well understood, although it is likely multifactorial. The mortality is high, associated with a late diagnosis and a rapid deterioration. A 4-month-old male domestic shorthair kitten presented for evaluation of intermittent respiratory distress and abdominal discomfort with two weeks of evolution. Based on clinical history, clinical sings and imaging studies a diagnosis of intermittent gastroesophageal intussusception was established. The reduction of the intussusception was performed with endoscopy maneuvers and with medical and nutritional management for some days, but this failed and finally was reduced with a percutaneous gastropexy tube to prevent recurrence with a good long-term outcome. Gastroesophageal intussusception in cats is associated with megaesophagus or hiatal hernia, and should be considered as a differential diagnosis in patients with chronic vomiting, regurgitation or respiratory disease. Survey and contrasted thoracic radiographs can be used to identify gross anatomical abnormalities, but the definitive diagnosis should be made by esophagogastroscopy with the possibility of reducing the intussusception. The use of percutaneous gastropexy provides other possible option to conventional surgery for the management of this pathology in cats.

Acute gastroesophageal intussusception in a juvenile Australian Shepherd dog: endoscopic treatment and long-term follow-up

Background

Canine gastroesophageal intussusception (GEI) is a rare and potentially fatal disease usually affecting puppies or young dogs < 3 months of age and of medium to large breeds. Surgical intervention has been advocated as the therapy of choice by most authors. Endoscopic treatment may offer an advantageous or alternative method of treatment.

Case presentation

GEI was diagnosed in a nine-week-old Australian Shepherd dog with an acute onset of vomiting and regurgitation and compatible radiographic findings on thoracic radiography. Treatment consisted of endoscopic gastric repositioning and placement of a percutaneous endoscopic gastrostomy (PEG) tube to prevent repeated dislocation of the stomach, and to allow for nutritional supplementation During a follow- up period of eight months, thoracic radiographs were obtained showing persistent esophageal dilatation in the absence of compatible clinical signs.

Conclusion

Endoscopic intervention is an effective, alternative in selected canine GEI- cases, allowing for rapid, minimally invasive confirmation of diagnosis and therapy. After initial treatment, radiographic long-term follow-up seems prudent even in asymptomatic patients.

Nonsurgical Treatment of Gastroesophageal Intussusception in a Puppy

A 7-week-old, female Siberian husky was presented to Murdoch University Veterinary Hospital with an acute onset of respiratory distress and regurgitation. Thoracic imaging identified an intraluminal esophageal mass with concurrent aspiration pneumonia. Esophagoscopy identified the mass as stomach, and a diagnosis of gastroesophageal intussusception was made. The intussusception was reduced endoscopically, and fixation of the stomach to the abdominal wall was performed using a tube gastropexy. Gastroesophageal intussusception is an uncommon disease in small animals and traditionally has been managed surgically. This case report describes an alternative method of treatment associated with a good outcome in this puppy.

Idiopathic megaoesophagus and intermittent gastro-oesophageal intussusception in a cat

An eight-month-old domestic shorthair cat was presented with chronic vomiting for three months, with an acute increase in frequency during the past two days. A diagnosis of megaoesophagus was made by chest radiography. Diagnostic work-up for megaoesophagus was performed. A gastro-oesophageal intussusception was identified during endoscopy. Medical and nutritional therapy was instituted with a good response to the treatment.

Concurrent gastro-oesophageal intussusception, trichobezoar and hiatal hernia in a cat

CASE HISTORY

An adult male Birman cat was evaluated for recurrent, intermittent vomiting or regurgitation, occasionally associated with abdominal discomfort.

CLINICAL FINDINGS AND DIAGNOSIS

Radiographs, including an oesophogram, indicated an oesophageal obstruction. Prior to treatment, the cat's condition deteriorated and it was euthanised at the owner's request. Post-mortem examination revealed a gastro-oesophageal intussusception, a trichobezoar impacted into the intussusceptum, and a dilated oesophageal hiatus consistent with a chronic hiatal hernia.

CLINICAL RELEVANCE

Gastro-oesophageal intussusception is a rare condition in cats. Its aetiology in relation to a pre-existing hiatal hernia and a trichobezoar is discussed.
