The symptoms of obstruction vary according to the cause, location, nature and degree, but most of them have four common symptoms such as abdominal pain, bloating, vomiting and constipation. There are many causes of obstruction, such as pyloric hypertrophy, intestinal atresia, intestinal adhesions, megacolon, etc.
Intestinal atresia is a cause of intestinal obstruction, which usually occurs in infants and children, most often from 6 to 12 months of age. In pediatric emergencies, intestinal obstruction caused by intestinal atresia, small intestinal hernia, congenital intestinal malformation, intestinal adhesions, etc., are more common.
Dynamic intestinal obstruction is caused by abnormal operating dynamics of the intestine itself, and there is usually no organic intestinal luminal stricture. Hematologic intestinal obstruction is less common. Mechanical intestinal obstruction is the most common, due to mechanical causes such as intestinal luminal stricture, peritoneal adhesions, intestinal entrapment, intestinal torsion, and other mechanical causes of obstruction, commonly due to congenital intestinal malformation, small intestinal hernia, and intestinal roundworm mass.
Generally, simple mechanical intestinal obstruction is characterized by paroxysmal severe colic, which is manifested by paroxysmal crying in infants and young children because they cannot express it; vomiting occurs within a short time after the obstruction, initially as reflex vomiting, and later as vomiting caused by reflux of intestinal contents into the stomach; abdominal distension usually starts to appear after the occurrence of obstruction for some time. After the occurrence of obstruction, anal defecation and exhaustion will stop and constipation will appear.
As the condition of intestinal obstruction changes rapidly, it needs to be diagnosed and treated early. Delay in diagnosis and treatment will aggravate the development of the disease and seriously affect the life of the child, so it is recommended to go to the hospital for treatment in time.
