The recovery time of endoscopic mucosal resection depends on the operation site and the scope of resection, and there is no uniform fixed standard. Endoscopic mucosal resection refers to the endoscopic resection of lesions in the mucosal layer under the guidance of endoscopes such as gastroscopes and enteroscopes, and is commonly used for the treatment of early tumors in the digestive tract. If the scope of resection is not large and the patient is in good physical condition, it is usually necessary to lie down for about 3 days after endoscopic mucosal resection for the initial healing of the surgical wound. It is recommended to eat light, easy-to-digest food, gradually transitioning from liquid to solid diet, and after initial healing, it is necessary to pay attention to not strenuous activities, as well as eating nuts and other indigestible food, and generally about 3 months can be basically back to normal. If the resection area is large or inflammation occurs at the surgical site, the recovery time will be longer. The specific recovery time may vary depending on the patient’s physical condition, nutritional supplementation during recovery, and whether there is recurrence or infection.
