Transhiatal esophagectomy for esophageal cancer

The two main approaches currently used for surgical treatment of esophageal cancer are transhiatal esophagectomy (THE) and esophagectomy through a right thoracotomy. Among technical variations of THE, wide opening of the diaphragm with ample mediastinal exposure allows resection under direct view with acceptable postoperative morbidity and mortality rates. Transthoracic esophagectomy associated with extensive mediastinal lymphadenectomy, still offers the best chance of definitive cure in intermediate stages (stages II and III), but does not influence survival in advanced cases (stage IV). In early stages, the lymph node invasion rate is negligible and may be treated by other techniques (THE or endoscopic mucosectomy). THE restores oral ingestion and avoids respiratory complications of thoracotomy, and consequently can be reserved for early cases (mucosal or submucosal lesions) or for patients with poor clinical status. To improve results of surgical treatment, protocols of associated radiochemotherapy are currently under research. (C) 1997 Wiley-Liss, Inc.
