It has been shown that biological patterns differ according to the presence (+) absence (-) of Barrett's epithelium (BIM) and of gastric intestinal metaplasia (GIM) in the fundus and antrum. Lymphatic metastatic spreading may differ according to the type of tumor.\n\nPreoperatively patients underwent histological search for Barrett's esophagus (BIM) in mucosa surrounding (ADEC) and intestinal metaplasia in the gastric corpus and antrum mucosa (GIM). Patients in which BIM was documented underwent sub total esophagectomy and gastric pull up (group 1), others underwent esophagectomy at the azygos vein + total gastrectomy with Roux Y esophagojejunostomy (group 2).
