title: Congenital Paraesophageal Hernia in a Cat.
abstract: A 3 mo old male domestic shorthair weighing 2 kg was presented for acute onset of anorexia, lethargy, paradoxical breathing, and a palpable mass effect in the cranial abdomen. Initial diagnostics and imaging suggested a pleuroperitoneal or hiatal hernia. Emergency abdominal exploration was performed, and a complex type II paraesophageal hiatal hernia was identified. The entire stomach, greater and lesser omenta, spleen, left limb of the pancreas, and the proximal segment of the descending duodenum were herniated through a discrete defect in the phrenicoesophageal ligament. After reduction of the herniated organs back into the abdomen, a phrenicoplasty, esophagopexy, and left-sided fundic gastropexy were performed. The cat recovered uneventfully from the procedure and was free of any signs of disease for at least 30 mo postoperatively. This is the first detailed report of the findings and successful surgical treatment of a complex congenital, type II paraesophageal hiatal hernia with complete herniation of the stomach, omenta, and spleen in a cat.
