Abstract
A 1-month-old male Chihuahua presented with a 3-day history of milk regurgitation and lethargy. The owner reported accidentally stepping on the puppy’s abdomen prior to presentation. Radiography and computed tomography (CT scan) revealed gastroesophageal intussusception. Surgical intervention, including caudal sternotomy and gastropexy and placing esophagostomy tube, was performed. The postoperative period was complicated by regurgitation, megaesophagus, and pancreatitis. Fluoroscopy confirmed esophageal dysmotility. Sildenafil was added to the treatment plan, resulting in clinical improvement. At 2 years of age, the patient had no clinical signs and maintained a normal quality of life. Early diagnosis, timely surgery, and long-term management were key to the successful outcome.
