Thoracoscopic enucleation of esophageal leiomyoma: a retrospective study on 40 cases

Esophageal leiomyoma is the most common benign esophageal tumor. Thoracoscopic enucleation is currently a preferred approach to most of these lesions. We present our experiences of enucleation of these tumors using thoracoscopic approach. A retrospective review of 40 patients who underwent enucleation of esophageal leiomyoma from 1997 to 2007 in our institute was conducted. Presenting symptoms, operative approach, tumor size, tumor shape, outcomes, and indication for this approach were analyzed. Forty patients were identified. Postoperative histopathology confirmed the leiomyoma in all patients. The thoracoscopic enucleation was completed in 34 cases, and the operation was converted to open procedure in six cases. Reasons for conversion included too small tumors to be visualized in two cases, thoracic cavity adhesion in one case, and the too large tumors in three cases. The median operating time was 70 min (50 to 210 min). Mean tumor size was 3.7 cm (0.5-10 cm). There were no major postoperative complications. Symptoms especially dysphasia were relieved postoperatively. Short- and long-term follow-up was satisfactory with none of the patients having tumor recurrences or other problems. Thoracoscopic enucleation of esophageal leiomyoma is technically safe and effective. It is currently the best choice for management of esophageal leiomyoma 1 to 5 cm in diameter. It can also be tried on a tumor larger than 5 cm, although the possibility of conversion to thoracotomy increases along with tumor growing and surrounding the esophagus.http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000265069500012&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701Gastroenterology & HepatologySCI(E)PubMed18ARTICLE3279-2832
