[Substantiation of the expediency of performing extensive lymph node dissection in surgical treatment of esophageal cancer].

The performance of extensive lymph node dissection+ in esophageal carcinoma is substantiated. From their own data the authors conclude that squamous cell carcinoma of the esophagus possesses high lymphatic metastatic activity and point to the statistically significant increase of the incidence of involvement of the superior perigastric lymph nodes in localization of the tumor in its infrathoracic part. At the same time, the frequency of affection of the mediastinal lymph collector does not depend on the localization of the tumor. The authors emphasize that extensive subsequent lymph node dissection+ of the mediastinum and upper part of the abdominal cavity should be an obligatory stage of an operative intervention in esophageal carcinoma.
