Abstract
The fundamental principle of surgery for intestinal cancer is mesenteric excision. It has been widely accepted as radical surgery for colorectal cancer, and it comprises procedures such as complete mesocolic excision for colon cancer and total mesorectal excision for rectal cancer. So far, the concept of mesenteric excision of the esophagus has not been well documented, but our surgical experience with a magnified view using a thoracoscope and understanding of the surgical anatomy based on embryologic foregut development has led us to introduce the concept of mesotracheoesophagus. Using this concept, our technique is reproducible, effective, and safe for lymph node dissection along the left recurrent laryngeal nerve. Here we report our concept, procedure, and results of thoracoscopic esophageal cancer surgery.
