The full name of ESD is EndoscopicSubmucosalDissection, and the Chinese name is endoscopic submucosal dissection. It is a minimally invasive surgical technique for endoscopic resection of digestive tract tumors. It is commonly used to remove diseases such as early gastric cancer and early esophageal cancer. Through the endoscopic lens, the doctor can accurately locate the tumor in the patient's body and cut, dissect and remove the submucosal layer to achieve the purpose of tumor removal. Compared with traditional surgical methods, ESD is less harmful to patients, has faster postoperative recovery, and has great advantages in preserving organs and reducing pain.
Compared with traditional surgical methods, ESD has its unique advantages. First of all, ESD can complete the operation under local anesthesia, avoiding the risks of general anesthesia. Secondly, ESD surgery causes very little damage to surrounding tissues, avoiding post-operative wound pain and complications during recovery. In addition, the entire tumor removed by ESD surgery is stored outside the body, which facilitates subsequent pathological examination and ensures the effectiveness and accuracy of the surgery. In addition, ESD operation technology is very mature, and doctor experience and professional ability are important factors in the success rate of ESD surgery.
Although ESD surgery has many advantages, it is still limited in terms of indications. For example, ESD surgery often requires highly skilled doctors and special endoscopic equipment, and some areas with poor medical conditions are unable to provide ESD surgery services. In addition, because ESD surgery is closely related to the size, location, and depth of the tumor, ESD surgery is not suitable for all digestive tract tumors. Large tumors and tumors in areas of mesenteric dysfunction may require surgical resection. Therefore, doctors need to conduct a detailed assessment of the patient and determine the surgical indications to maximize the advantages of ESD and bring more benefits to the patient's treatment.
