[Strangulated retrocostoxiphoid hernia. Review of the published literature and report on two cases (author's transl)].

Two cases of strangulated retrocostoxiphoid hernia (Morgagni-Larrey hernias) are reported. This is a relatively rare complication, as only 66 cases have been reported, and it has a poor prognosis. The clinical picture includes three main symptomatological groups: occlusion of the colon, gastric volvulus, and small intestine occlusion. Radiological examination of the lungs by frontal and profile films is usually sufficient to establish the diagnosis rapidly, and whether surgery is indicated. In some cases, however, the symptoms are such that opacification with water soluble agents is required. Reduction of the visceral hernia and closure of the orifice is carried out after laparotomy, resection of viscera being rarely required.
