Repair of large paraesophageal hernia with complete intrathoracic stomach

Abstract

Paraesophageal hiatal hernia accounts for only five per cent of all diaphragmatic defects but is a potentially dangerous lesion. Herniation of the entire stomach, at times accompanied by the omentum, transverse colon, and small bowel, may occur in some patients, and incarceration and strangulation may be the result. Three patients underwent repair of large paraesophageal hernias, in one instance as an emergency. Symptoms of pain, bloating, and occasional regurgitation had been present for 17, 30, and 40 years. The operations included repair of the hiatal defect, anterior gastropexy, and Nissen fundoplication in two patients. In the third patient, a pyloromyotomy was performed as well. A subsequent thoracotomy was necessary in one patient to excise a persistent large hernia sac, which was densely adherent to the lung and mediastinal structures. All patients were asymptomatic after periods of 9 months, 1 year, and 7 years. The unique anatomic and clinical features of large paraesophageal hernias containing intrathoracic abdominal viscera, as well as the technique of operative repair, are presented.
