[Intestinal occlusion caused by Morgagni-Larrey diaphragmatic hernia]

Morgagni-Larrey's hernias, which are both infrequent and generally asymptomatic, are often diagnosed by chance during routine diagnostic tests performed for other pathologies. Usually congenital in adults, they are often small or only take the form of a pre-hernia lipoma. Intestinal occlusion is rarely described and frequently entails diagnostic difficulties before hydroaerial levels are demonstrated in the thoracic region. In these cases, surgery using an abdominal approach should be preferred in order to treat compressed abdominal viscera at the same time and to exclude the bilateral nature of the lesion. The authors present two cases of an adult man and woman who were referred to their attention for occlusive pathologies. Both were operated using a laparotomy approach. The reduction of abdominal viscera did not present any difficulties. The hernial sac was only removed in the first patient. Plastic surgery was completed by attaching the diaphragmatic flap to the costal and sternal wall using separate non-reabsorbing suture stitches. No complications were reported.
