Is gastric juice returned by gastric tube under intestinal obstruction more normal

The gastric juice returned from the gastric tube under intestinal obstruction is mostly normal. Because of the obstruction of the digestive tract, food cannot be discharged from the anus and can only accumulate at the obstruction site. If there is infection in the local mucosa, this will lead to edema and congestion of the mucosa, resulting in the secretion of inflammatory cells, causing the gastric juice to resemble sputum.
