[Spontaneous contained perforation of a hiatal hernia. A new equivalent of Boerhaave's syndrome].

The authors report the case of an alcoholic 49-year-old man hospitalized because of epigastric pain and hematemesis. Upper endoscopy showed a tear in a hiatus hernia (interpreted as a Mallory-Weiss lesion) and a bleeding duodenal ulcer. Upper barium examination performed 16 days later revealed a mediastinal collection communicating with the hiatus hernia. Retrospective evaluation of chest roentgenograms obtained at admission showed a limited mediastinal gas collection. With medical management, the collection progressively disappeared. From a theoretical point of view, this case illustrates Watts' theory on the effect of hiatus hernia on the site of postemetic injury. From a practical point of view, it confirms that conservative management is indicated in contained spontaneous perforations.
