Second: pylorus is the most narrow part of the digestive tract, the normal diameter is about 1.5cm, so it is prone to obstruction. Due to * pyloric obstruction, the stomach contents can not enter the intestines smoothly, but a large amount of retention in the stomach leads to muscular thickening of the gastric wall, enlargement of the gastric cavity and inflammation, edema and erosion of the gastric mucosa. And a lot of vomiting, leading to severe malnutrition, hypoproteinemia and anemia, and severe dehydration.
