Intussusception is a segment of the intestine that is trapped in the lumen of the intestine to which it is attached and causes obstruction to the passage of intestinal contents. Intussusception accounts for 15% to 20% of intestinal obstruction. There are two types of intussusception: primary and secondary. Primary intussusception mostly occurs in infants and children, while secondary intussusception is more common in adults. The vast majority of intussusception is the proximal intestine to the distal intestine into the intussusception, reverse intussusception is rare, less than 10% of the total number of cases.
Clinical manifestations 1, mostly in infants and children, especially children under 2 years old.
2. Typical manifestations: abdominal pain, vomiting, blood in stool and abdominal mass.
3, adults intussusception clinical manifestations are not as typical as in young children, often showing chronic recurrent attacks, less often occurring bloody stools. Adult intussusception is mostly associated with organic diseases (especially intestinal polyps and tumors).
The first typical feature is abdominal pain, and it is acute paroxysmal abdominal pain. For example, if the child is playing or doing something else, he or she may suddenly feel abdominal pain that makes him or her cry, or even break out in a cold sweat, or roll around and turn pale; however, some may not cry loudly, but may suddenly feel very irritable, and then return to normal after a while.
The second typical feature is bloody stools. Blood in the stool is one of the most important symptoms of intussusception. First of all, blood in the stool may be normal for us, because sometimes blood in the stool may occur as a result of fire, but if it doesn’t work within a week after treatment, it is necessary to seek prompt medical attention. It is possible that intussusception has occurred. The color of the stool will change after the onset of this disease.
The third typical feature is a lump in the abdomen. It may not be visible normally, but if the baby is quiet or sleeping, their abdominal wall is more relaxed and their muscles are looser, so if we feel it with our hands, we are likely to feel a hard lump, which is a clear symptom of intussusception. If this symptom occurs, you must seek medical attention early.
This symptom usually occurs after the abdominal pain. At first, the vomiting will be more frequent, but over time, the number of vomiting may decrease, but the vomit will have a certain odor.
