Abstract
Minimally invasive esophagectomy (MIE) is a feasible technique that has been shown to be safe for the treatment of esophageal cancer. Chylothorax remains a challenging and potentially life-threatening postoperative complication of MIE. In this retrospective series, we evaluated the results of preventive intraoperative thoracic duct ligation in patients who underwent video-assisted thoracoscopic esophagectomy for cancer. From May 2009 to June 2010, 70 video-assisted thoracoscopic esophagectomies for cancer of the esophagus (group A) were performed without prophylactic thoracic duct ligation. Since June 2010, 65 patients (group B) with esophageal cancer underwent video-assisted thoracoscopic esophagectomy with routine ligation of the thoracic duct during the operation. No intraoperative or postoperative complications directly related to thoracic duct ligation were recorded. Postoperative chylothorax occurred in seven patients in group A and in one patient in group B (P = 0.0375). The results of this study suggest that thoracic duct ligation during video-assisted thoracoscopic esophagectomy for cancer is an effective and safe method for prevention of postoperative chylothorax.
