After total gastrectomy surgery, generally about 2-3 days in the anus gas defecation can drink water, but if there is still drainage of bloody liquid need to be based on the drainage situation. For multiple tumors and larger tumors, the whole stomach is usually resected, and the operation style is to cut off all the stomach and anastomose the jejunum and esophagus to each other. After making sure that the jejunum and esophagus are firmly anastomosed and there is no drainage of hemorrhagic fluid, after anal defecation, a small amount of water can be consumed about 2-3 days after surgery. Initially, the amount of water should not be too much, so as not to overload the intestines and crack the anastomosis. If there is still no defecation and the drainage is not yet clean, then you can’t drink water. At this time, the anastomosis may not have recovered, and the water may enter the abdominal cavity through the opening, causing infection and affecting the postoperative recovery. Therefore, whether you can drink water or not should be based on the doctor’s advice, to clarify the recovery situation, so as not to affect the recovery time and recovery effect.
