The characteristics of surgical treatment of cardia cancer mainly include standardization of surgery, surgical resection rate, surgical cure rate, significant improvement of postoperative survival rate, surgical mortality rate, and significant reduction of complications. Surgical treatment is the preferred method for cardia cancer, and the characteristics of specific surgery include. 1. resection of pancreatic cancer, digestive tract reconstruction and intrathoracic anastomosis via left thoracic or combined thoracic-abdominal incision:The feature is that the lesion area in the mid-thoracic section and below of the patient is well exposed, which is conducive to the more convenient operation and precise resection of the diseased tissues during the operation. 2. cardia cancer resection with digestive tract reconstruction and intrathoracic anastomosis via two incisions in the right upper thoracic abdomen: characterized by the possibility of obtaining a better view during the treatment of the odd vein and precise treatment of the lymph nodes around the esophagus. 3. Transabdominal cardia cancer resection, transesophageal cleft digestive tract reconstruction:Characterized by enabling a wide exposure field, adequate resection of the lesion area in the lower part of the esophagus, and more convenient dissection of the thoracic lymph nodes. Through surgical treatment, the survival quality, psychosocial and other aspects of cardia cancer surgery patients have been improved.
