Gastric ese endoscopy generally refers to gastroscopic ESD, which refers to endoscopic submucosal dissection, and recovery is usually 7 to 14 days after the procedure, with the exact recovery time varying from person to person. Gastric endoscopic submucosal dissection is a minimally invasive procedure for the endoscopic treatment of lesions in the digestive tract such as the stomach and duodenum. This surgical procedure has the advantage of being less invasive and faster postoperative recovery. For young patients, there are mostly no postoperative complications and recovery usually takes 7 days; if the stripped area is large and the person is in poor health, recovery may take 14 days. Endoscopic submucosal dissection only removes the lesion locally, and cannot clear the surrounding lymph nodes. A comprehensive assessment of the size of the lesion and whether metastasis has occurred is required before the operation. After endoscopic submucosal dissection, it is recommended to follow the doctor’s instruction to eat, and consult the supervising physician immediately when discomfort occurs to avoid delaying the condition.
