[Retro-costo-xyphoid hernia in adults. Apropos of 3 cases].Chirurgie. 1992; 118(1-2):59-62.C
Three cases of retrosternal diaphragmatic hernia (Morgagni hernia) are reported. Diagnosis have been made by conventional radiology (Chest X-ray, Upper G-I series) in 2 cases: the third one was found incidentally during a laparotomy. Peritoneography, CT scan, NMR are recommended in the difficult cases. ONe case presented as acute gastric outlet obstruction secondary to an intra-thoracic volvulus of the herniated stomach. Surgical treatment is indicated in all cases of retrosternal diaphragmatic hernia because of the high-risk of complications (gastric volvulus, colonic obstruction). Surgery through an abdominal approach is preferred and post-operative course is benign.
