Incarcerated parahiatal hernia with gastric necrosis

A parahiatal diaphragmatic hernia developed five years after transthoracic Heller myotomy. Failure to recognize this complication resulted in strangulation and necrosis of the gastric fundus. To our knowledge, this is the first reported case of a postoperative parahiatal hernia that did not follow the use of a diaphragmatic counterincision. Prompt recognition of this complication will prevent unnecessary morbidity and mortality.
