If patients with intestinal obstruction have abdominal distension and pain, the best way is to promptly lower the gastrointestinal decompression, through gastrointestinal decompression can effectively induce gas and gastric juice in the stomach, which can partially relieve the distension and pain of intestinal obstruction. The enema can effectively stimulate the peristaltic movement of the rectum, so that the gas or food residues and feces accumulated in the intestine can be effectively expelled, which can also relieve the problem of stomach distension and pain.
