Laparoscopic repair of Bochdalek hernia with intrathoracic kidney in a 2-year-old child.

Intrathoracic kidney with Bochdalek hernia is a very rare congenital anomaly. Some case reports have discussed repair by laparotomy or thoracotomy. We report a case in a child performed using a laparoscopic approach. A 2-year-old boy arrived at our hospital with gastric volvulus caused by a left-sided Bochdalek hernia. CT also showed a left-sided intrathoracic kidney. After conservative therapy for the volvulus, laparoscopic repair of the diaphragmatic hernia was performed. The key problem during the operation was the presence of the intrathoracic kidney. If direct closure of the hernia had been performed without the intrathoracic kidney having been relocated to the abdomen, a complete closure would have been impossible because of the renal vessels. After the intrathoracic kidney was relocated to the abdomen, the diaphragmatic defect was closed. The boy has been doing well without complications for 5 years, and CT reveals that the left-sided kidney is almost normally positioned.
