Complications of congenital posterolateral diaphragmatic hernia in the adult. Report of two cases and literature review.

The literature on incarceration in Bochdalek hernias in adults is rather limited. Our purpose is to present two cases of this lesion that were treated surgically in the past ten years. The first patient, a 32 year old female was admitted in shock with an 8h history of left chest pain and dyspnoea. Chest X-ray showed a pleural effusion in the left hemithorax. Chest tube drainage revealed gastric fluid. We operated on her immediately, through a left thoracotomy, and found rupture of the stomach into the left pleural cavity. Strangulation of the fundus of the stomach due to congenital diaphragmatic hernia, Bochdalek's type, was found to be the cause of the rupture. We performed resection of the gangrenous segment of the stomach with primary closure. The second patient a 48 year old man was admitted with symptoms of large bowel obstruction. Per os gastrographin study showed the splenic flexure herniated into the left hemithorax. At the operation, through a paramedian left incision, the herniated large bowel was reduced back into the abdomen. In both cases the defect of the left hemidiaphragm was sutured with interrupted silk sutures. Both patients had an uneventful postoperative course. The diagnosis of Bochdalek hernia in the adult is usually made in case of complications, and that demands an immediate surgical repair.
