What is pyloric obstruction

summary

The harm of pyloric obstruction is very serious, which usually affects the normal eating, accompanied by vomiting and severe dehydration. Let's see what pyloric obstruction is.

What is pyloric obstruction

First of all: 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, gastric 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.

Secondly: clinically, the patient can not eat normally for a long time, and vomit a lot, leading to severe malnutrition, hypoproteinemia and anemia, and severe dehydration, hypokalemia, alkalosis and other water and electrolyte disorders.

Finally: the ulcer located in or near the pylorus may be due to mucosal edema, or the ulcer may cause reflex pyloric circular muscle contraction. The more common reason is chronic ulcer caused by submucosal fibrosis, the formation of cicatricial stenosis.

matters needing attention

The patients with mild obstruction symptoms can be given liquid diet. The patients with severe obstruction symptoms should fast and quickly establish venous channels. Due to a large number of frequent vomiting, the patients are prone to malnutrition. Attention should be paid to supplement energy and influence substances.
