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.
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.

ABSTRACT: This case report describes the ultrasonographic diagnosis of gastroesophageal intussusception in a male 7 week old German Shepherd Dog. The patient had no history prior to being purchased from a breeder 24 hours before presentation. The owners noted persistent intermittent vomiting since that time and a single roundworm was identified once in a vomitus. A gastroesophageal intussusception was diagnosed via thoracic radiographs and trans-abdominal ultrasound. The spleen was noted to be within the distal esophagus in concert with the stomach. Reduction of the intussusception was performed via laparotomy with bilateral gastropexy. The patient recovered uneventfully from surgery and is alive 4 months after discharge. This case highlights the potential advantages of ultrasound in the diagnosis of gastroesophageal intussusceptions. A review of the current literature is presented with discussions of possible etiologies of this rare form of intestinal intussusception.
