Most of the cardia low-differentiated cancer can be minimally invasive surgery, but those that are difficult to accomplish by minimally invasive surgery still need traditional incision surgery to treat. Most of the cardia low differentiated carcinoma can be free and resected by laparoscopic surgery, and regional lymph node dissection, complete or partial gastric resection, anastomosis of jejunum or residual stomach and esophagus can be performed according to the tumor condition. However, due to the reason of surgical operation, not all processes can be operated laparoscopically, such as complete gastric resection and jejuno-esophageal anastomosis need to be carried out after a small incision under the xiphoid process. In addition, cardia low-differentiated carcinoma is easy to involve the surrounding tissues in most cases, for the invasion of the surrounding tissues, or when it is difficult to free the surrounding tissues of the tumor under the microscope, the minimally invasive surgery is not conducive to the surgical resection on the contrary, so it needs to be treated by traditional incision surgery. Therefore, the treatment of low-differentiated cardia cancer requires specific analysis of specific problems, and the suitable surgical method should be decided by professional doctors after evaluation.
