Intussusception is a common pediatric surgical condition in infancy and early childhood. It is characterized clinically by abdominal distension, abdominal pain, and the passage of jelly-like stools. Mild cases of intussusception can usually be treated in a clinical setting with an air enema under surgical guidance. However, severe intussusception, which has led to ischemia or necrosis of the intestinal mucosa, must be treated surgically. Therefore, the treatment of intussusception is not difficult, but it is crucial to avoid misdiagnosis. With timely diagnosis, the condition is relatively easy to manage with the best and most appropriate treatment, where diagnosis is the most critical aspect.

Pediatric intussusception should see which department?

Intussusception often occurs in infants and young children, so the main symptoms are vomiting, bloody stools, and abdominal pain. Therefore, the initial consultation is usually in pediatric emergency. When intussusception is suspected as a cause of acute abdomen, the doctor will conduct intestinal tube and abdominal ultrasound examinations. If the ultrasound confirms intussusception, a transfer to pediatric surgery or emergency surgery may be considered for appropriate surgical treatment. Thus, the initial choice for consultation is usually pediatrics, but after a diagnosis is confirmed, treatment should be transferred to pediatric surgery.

Typical symptoms of intussusception in children

The typical symptoms of intussusception include abdominal pain, which initially presents as sudden, severe, crampy pain. The affected child may cry, appear restless, draw their knees up to their stomach, and have a pale complexion. The pain may last several minutes or longer and then relieve, with repetitions every ten to twenty minutes. The second symptom is vomiting, which is an early symptom that initially may include curdled milk and food residues, and later may contain bile or fecal matter. The third symptom is bloody stools, where approximately 85% of affected children may pass jelly-like mucus and blood within six to twelve hours of onset. An abdominal mass is often found in the upper right abdomen, and a sausage-shaped mass that is slightly movable upon touch can be felt beneath the ribs. Regarding the overall condition of the child, they may be able to attend school in the early stages without showing signs of toxicity. As the condition progresses, complications such as bowel necrosis or peritonitis can develop, leading to worsening systemic symptoms, including severe dehydration, high fever, drowsiness, coma, or shock.

Can intestinal intussusception have bowel movements?

After the occurrence of intussusception, the patient's symptoms often manifest as those of intestinal obstruction, causing significant abdominal pain, cessation of gas and stool passage through the anus, and a palpable abdominal mass can be felt. Imaging studies can clearly indicate signs of intussusception. Once intussusception occurs, the patient stops passing stool, and symptoms such as vomiting and nausea also occur. Once diagnosed, it is crucial to treat promptly, including air enema reduction or surgical treatment, to promptly address the symptoms of intussusception, prevent the worsening of intestinal obstruction symptoms, and avoid severe complications such as intestinal necrosis, which can endanger the patient's life.

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.

Early symptoms of intussusception in children

Intussusception in children refers to a segment of the intestine telescoping into the adjoining lumen, causing an obstruction to the passage of intestinal contents. Intussusception accounts for 15%-20% of intestinal obstructions and can be primary or secondary. Generally, primary intussusception is more common in infants and young children. Early symptoms may include bloating, abdominal pain, vomiting, possibly accompanied by bloody stools, and a palpable mass in the abdomen. Moreover, intussusception can occur in multiple locations, such as jejunum into jejunum, jejunum into ileum, ileum into ileum, ileum into cecum, ileum into colon, colon into colon, etc. Among these, ileo-cecal intussusception is the most common, while small intestine into small intestine and colon into colon are relatively rare.
