Pyloric stenosis: clinical picture, diagnosis, treatment, prevention. (or “How to prevent narrowing of the pylorus of the stomach?” - version of the title, in 2 parts).

Pylorostenosis (pylorostenosis, pylorospasm, volvulus, painful peritonitis, alimentary intestinal obstruction) is a narrowing of the pyloric (pyloric) part of the stomach (entrance to the duodenum). The pathology is caused by enlargement and hypertrophy of the pyloric muscles. It usually occurs in childhood and is manifested by obstruction of the pyloric zone, which is often accompanied by constipation over time and, as a consequence, the development of fecal blockages, as a result of which subperitoneal inflammation develops. In newborns, this is a blocked segment of the intestine, which is located at the bend of the intestine connecting the stomach and small intestine. A pronounced functional or anatomical frenulum prevents the passage of food from the stomach into the duodenum of the small intestine and thereby impairs nutrition and reduces water absorption.

Most often, the root causes of such disorders are congenital defects.
