Intussusception is a life-threatening emergency, and its reduction is an urgent treatment measure that should be performed immediately once confirmed. It is a common acute abdomen disease in infants and young children. Initially, the general condition may be good, but as the disease progresses, the condition worsens, leading to systemic deterioration, complications such as intestinal necrosis or peritonitis, and severe symptoms of poisoning such as severe dehydration, high fever, lethargy, coma, and shock.

Can infants with intussusception sleep?

Intussusception presents as abdominal pain, which occurs in sudden, severe, and periodic episodes. The child cries restlessly with a pale face, and the pain lasts several minutes or longer. The pain then subsides, and during this relief, the child falls asleep. The pain reoccurs every ten to twenty minutes. Continuous episodes occur until the intussusception is successfully reduced, after which the child calms down and falls asleep without further crying or vomiting.

Infant intussusception typical symptoms

The typical clinical manifestations of intussusception are as follows: Firstly, abdominal pain, which occurs in paroxysmal, regular episodes, characterized by sudden onset of severe colicky pain. The child appears restless and cries, with knees drawn to the abdomen, pale complexion, and relief coming after several minutes or longer; the pain reoccurs every ten to twenty minutes. Secondly, vomiting is an early symptom, initially reflexive containing milk curds or food residues, later possibly containing bile, and in the late stage, fecal-like liquid may be vomited. Thirdly, bloody stools are a significant symptom, appearing within the first few hours; initially, stools may appear normal, later becoming scanty or absent. In about 85% of cases, a jam-like mucousy bloody stool is passed within six to twelve hours of onset, or bloody stools are found upon rectal examination. Fourthly, abdominal mass is often found in the right upper quadrant just below the ribs, where a slight movable intussusception mass can be palpated, resembling a sausage.

Causes of intussusception in children

The causes of intussusception are divided into primary and secondary types, with 95% being primary, commonly seen in infants and young children. In infants, the mesentery of the ileocecal area is not yet fully fixed and has greater mobility, which is a structural factor prone to intussusception. Secondary cases account for 5%, where intussusception occurs. Some intestines show clear organic changes, such as Meckel's diverticulum, intestinal polyps, intestinal tumors, intestinal duplication anomalies, abdominal purpura, and thickening of the intestinal wall, which can cause intussusception of the intestines. Certain triggers, including dietary changes, viral infections, and diarrhea, can induce intussusception.

Causes of intussusception in children

The etiology of intussusception is divided into primary and secondary types, with 95% being primary, which is common in infants and young children. In infants, the mesentery of the ileocecal region is not yet fully fixed and has a larger degree of mobility, which is a structural factor conducive to the occurrence of intussusception. Secondary cases account for about 5%, often secondary to Meckel's diverticulum, intestinal polyps, intestinal tumors, intestinal duplications, and abdominal purpura causing swelling and thickening of the intestinal wall, which can lead to intussusception. Certain factors may cause a change in the rhythmic movement of the intestines leading to disorder, thereby inducing intussusception, such as changes in diet, viral infections, and diarrhea.

Can intussusception resolve itself automatically?

Some children with intussusception may resolve spontaneously, but it is important to closely monitor their condition with ultrasound to understand the status of the intussusception. If it does not resolve on its own in a short period, immediate surgical treatment is necessary. If the ultrasound shows successful resolution, or if the child's clinical symptoms such as vomiting and abdominal pain improve and the ultrasound does not reveal any obvious abnormalities, it is considered an automatic recovery.
