Siewert Type II Esophageal Adenocarcinoma: Relationship Between Histology and Survival

The esophagus was resected at the arch level of the azygos vein, a frozen section of the resection margin was routinely performed to achieve a proximal clean resection margin. The surgical specimen was comprehensive of distal esophagus, stomach and omentum. Digestive tract continuity was established with Roux-en-Y esophagojejunostomy. Lymphadenectomy was extended to the thoracic stations R 2-4, 7-8-9, and L 4, numbered according to the Mountain's classification \[39\] (Suppl. File 2 Figure A) and to the abdominal stations 1-12, numbered according to the Japanese Research Society for Gastric Cancer (JRSGC) 1998 classification.
