Use of mini-invasive procedures in esophageal surgery.

The authors have applied the advantages of mini-invasive surgery to the treatment of esophageal diseases. The technical possibilities of esophageal dissection have been investigated in patients with cancer of the intrathoracic esophagus. The mini-invasive techniques have been applied in the clinical setting to perform the esophagectomy through a trans-hiatal approach or by means of thoracoscopy. Performing the esophagectomy through the trans-hiatal approach allows an accurate mediastinal dissection and lymphadenectomy of the paraesophageal nodes. Performing the esophagectomy by means of thoracoscopy requires division of the azygos vein. In our experience better to divide the esophagus high in the chest. At present, trans-hiatal esophagectomy with mini-invasive procedures seems to be the technique of choice. However, the approach based on thoracoscopy will gain popularity with the development of more sophisticated instruments. In selected cases, it could be advantageous to use both techniques.
