[Pseudostriction of hiatal hernia. Apropos of a case with incarceration of the transverse mesocolon and small intestine].

Massive hiatal hernia is a lesion at risk of incarceration, volvulus, and obstruction. The true paraesophageal type is a very rare condition and probably often mistaken with end-stage slidind hernia. Furthermore reflux and oesophagitis are always possible. In this case report a small bowel loop was incarcerated with a massive hiatal hernia. This association was only possible because of the existence of an associated transverse mesocolis hernia giving way to the small bowel. An emergency operation was necessary. The need of surgical treatment of such lesions is stressed, if possible before acute complication, even if they are asymptomatic at the time of diagnostic, which is a quite common condition.
