Thoracoscopic vagotomy as a safe adjunct to remedial gastric surgery

Patients who have had prior subdiaphragmatic dissection with an incomplete vagotomy or Nissen fundoplication present added challenges when they require vagotomy and gastric resection. In this setting, thoracoscopic vagotomy offers significant advantages. A second attempt at vagotomy in a previously dissected field can be prolonged and frustrating. In addition to these concerns, repeat dissection can also lead to failure to find the vagal trunks, perforation of the esophagus, hemorrhage, and/or splenic injury. In our experience, three patients requiring gastrectomy or resection of a marginal ulcer have undergone thoracoscopic vagotomy at the time of transabdominal gastric surgery. The thoracoscopic approach avoided either a thoracoabdominal incision or combined thoracic and abdominal incisions while allowing dissection of the vagal trunks to be performed in normal tissue planes. The minimally invasive approach afforded decreased postoperative pain and excellent clinical results. Thoracoscopic vagotomy offers a welcome alternative to re-exploration of a previously dissected distal esophagus in search of vagal trunks, especially when they have been missed at the time of the first operation. Further application of this approach is recommended.
