Gastric endoscopic submucosal dissection does not require a gastric tube.
Gastric endoscopic submucosal dissection is a minimally invasive procedure for the treatment of gastrointestinal lesions, which requires preoperative fasting for at least 6 h and water fasting for at least 2 h. Gastric endoscopic submucosal dissection is difficult to perform, technically demanding and takes a long time to operate, so most of them require intravenous general anesthesia and general anesthesia for endotracheal intubation.
After gastric endoscopic submucosal dissection, acid-suppressing agents are usually applied routinely to increase intragastric pH, promote healing of medically originated ulcers, and reduce the occurrence of delayed bleeding. On the first postoperative day, fasting, close monitoring of vital signs changes, relevant laboratory tests and imaging tests, if the relevant examination is not abnormal, the second postoperative day can be liquid or soft food, and then gradually return to normal diet.
If there are complications such as perforation or bleeding, it is usually necessary to prolong the period of fasting and water fasting. Generally, there is no need to insert a gastric tube after the operation.
If there is any obvious discomfort after the operation, the patient should take into account the actual situation of the patient and cooperate with the doctor to give appropriate treatment and therapy to avoid serious consequences.
