Intussusception should be considered when the patient shows symptoms of intestinal obstruction, namely pain, vomiting, distension, and paralysis, along with cessation of gas and stool passing through the anus. In the early stages of intussusception, there may be a small amount of gas and stool passage, but the presence of intussusception should not be overlooked, and imaging studies can be performed for confirmation. If there is a fluid level in the intestinal lumen and clear signs of intestinal obstruction, and if the patient can feel a distinct mass in the abdomen, which on imaging shows concentric ring-like changes, intussusception should be considered. Once diagnosed, timely treatment is essential, thus treatment should not be delayed until there is an absence of stool and gas passage.

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.

Intussusception: How to Diagnose

Intussusception is one of the most common acute abdominal conditions in infants and toddlers, primarily seen in children under one year old. It refers to the condition where part of the intestine and its mesentery slip into an adjacent intestinal lumen, causing obstruction at the root of the intestine. The diagnosis of intussusception in children is mainly based on clinical symptoms. A previously healthy child may suddenly experience an episode of severe, regular, intermittent colicky pain. The child may appear restless, crying, with knees bent, a reduced amplitude of movement, and a pale complexion, with the abdominal pain easing after 10 to 20 minutes. The child may also vomit and pass bloody stools. Bloody stools are a very important symptom; approximately 85% of cases will pass jelly-like, mucousy bloody stools within 6 to 12 hours of onset, or even if there is no bloody stool visible, rectal examination can reveal its presence. A sausage-shaped mass can be felt in the abdomen. Furthermore, an ultrasound can show a typical image of a concentric circle or target-sign mass. Under ultrasound monitoring, procedures such as air or hydrostatic enema can be performed, which help in the early diagnosis of intussusception.

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.

How is intussusception in infants caused?

Intussusception is divided into primary and secondary types, with 95% being primary, commonly seen in infants. This is due to the fact that the mesentery at the ileocecal region in infants is not fully fixed and has greater mobility, which are structural factors that facilitate intussusception. For the 5% of secondary cases, these are more common in older children, whose intestines often have clear organic causes for intussusception. These causes include the inversion of a Meckel's diverticulum into the ileal lumen serving as a lead point; intestinal polyps, intestinal tumors, intestinal duplications, and abdominal purpura can cause thickening and swelling of the bowel wall leading to intussusception. Additionally, certain facilitating factors can disrupt the rhythm of intestinal peristalsis, thereby inducing intussusception. Changes in diet, viral infections, and diarrhea are among the factors that can trigger intussusception.

Why does intussusception cause bloody stool?

Once intussusception occurs, only a small portion of the small intestine intussusceptions can reset themselves. Due to the continuous spasm of the sheathed intestinal tract, microcirculatory disorders occur in the intussuscepted segment. Initially, venous blood flow is obstructed, leading to tissue congestion and edema, venous varicosity, and mucosal cells secrete a large amount of mucus into the intestinal lumen, which mixes with blood and feces to form a jam-like jelly substance that is expelled. The intestinal wall becomes edematous, and the obstruction of venous return worsens, affecting the arteries, resulting in insufficient blood supply, and leading to systemic toxic symptoms. In severe cases, intestinal perforation and peritonitis can occur.
