Resection of foregut-derived duplications by minimal-access surgery

Abstract

Eight children underwent minimal-access surgery (MAS) for duplications of foregut derivatives. The efficacy and safety of this approach are reviewed. The seven patients with mediastinal lesions had video-assisted thoracoscopic resection. One lesion presented as a subdiaphragmatic esophageal diverticulum, which was excised laparoscopically. Between March 1991 and October 1997, eight children were treated. Mean age was 27 months and mean weight was 11. 4 kg. Mean operating time was 106 min, and mean postoperative hospital stay was 4.5 days (median = 2 days). Persistent air leaks occurred in two patients who had centrally-located bronchogenic cysts. One of these, who had undergone subtotal excision with laser photoablation of the remaining cyst mucosa, developed a recurrence that was excised at thoracotomy. We conclude that esophageal and bronchogenic cysts and duplications may be safely excised by MAS in children, with excellent cosmetic and functional outcome. Two technical points are noted: (1) a thoracostomy tube is required for central mediastinal lesions; and (2) complete excision is required to prevent recurrence.
