ESD, or endoscopic submucosal dissection, allows you to walk on the floor a few hours after the surgery if the surgery goes well and no complications occur. The full name of ESD in Chinese is endoscopic submucosal dissection, which can be used for the endoscopic treatment of early gastric cancer and other diseases. After the mucosa around the lesion is cut with an electric knife under the endoscope, the lesion is peeled off between the submucosal layer and the muscle layer. If the surgery is completed successfully and there are no postoperative complications, you can walk on the floor a few hours after the surgery. Compared with open or laparoscopic surgery, ESD is a simpler endoscopic treatment and is now widely practiced in clinical practice. Early walking after surgery can speed up recovery, if the situation permits.
