Transthoracic esophagectomy compared to transhiatal extended gastrectomy for adenocarcinoma of the esophagogastric junction: an international retrospective cohort study.

Background: Optimal surgical treatment for esophagogastric junction Siewert type II adenocarcinoma is debated, being both transthoracic esophagectomy (TTE) and total extended gastrectomy (TEG) commonly performed. Potential advantages of TTE are represented by the longer proximal resection margin and by the more extensive mediastinal lymphadenectomy. On the other hand, esophagectomy is usually considered more invasive.
