Mediastinoscope-assisted transhiatal esophagectomy for esophageal cancer.
BACKGROUND
Transthoracic esophagectomy (TTE) is a radical strategy for treatment of esophageal cancer, and the morbidity and mortality are high. Transhiatal esophagectomy (THE) is advantageous because it avoids thoracotomy and has a shorter surgical time, but risk of intraoperative morbidity stresses the surgeon and lymph node sampling is not possible.


METHODS
Mediastinoscope-assisted transhiatal esophagectomy (MATHE) was performed in 42 patients with esophageal cancer. Patients with superficial esophageal cancer and medical risk were included. Feasibility and efficacy of this procedure are discussed by examining short- and long-term morbidity, mortality, and survival.


RESULTS
With the mediastinoscope, esophagectomy was performed safely under direct vision. There was only a small amount of bleeding, and surgical time was short. Little morbidity and no deaths were recorded.


CONCLUSIONS
MATHE is a safe and minimally invasive technique that allows direct visualization of mediastinal structures Lymph node sampling was feasible because of clear visualization of the mediastinum.
