A careful approach is required for managing esophageal perforation after thyroidectomy, and esophageal perforation can cause serious infectious complications. However, reports on the treatment and management of esophageal perforation after thyroidectomy are lacking. We report here on a case of esophageal perforation that was successfully managed using vacuum-assisted closure. A patient underwent total thyroidectomy for papillary carcinoma. Near the lower pole of the left thyroid, a metastatic lymph node with direct invasion to the esophagus was detected. The esophageal wall, which was injured during lymph node dissection, was repaired. An esophageal leak occurred on the 5^th postoperative day, and a 1 cm sized esophageal wall defect was identified. After irrigation, the defect was primary repaired, and the wound was closed using a vacuum assisted closure system. The patient was kept in a oral-fasting state, and subsequent wound dressing with vacuum change was repeated every 3∼4 days. During this period, gradual formation of granulation tissue was noted. After negative leakage was confirmed by an esophagogram on the 18^th postoperative day, the patient resumed an oral intake. The wound was closed successfully on the 22^nd postoperative day, and the patient was safely discharged one week later. In conclusion, vacuum assisted wound closure could reduce the risk of infection and also induce granulation tissue. We think this could be an alternative treatment strategy for esophageal perforation after thyroidectomy. (Korean J Endocrine Surg 2010;10:106-109)
