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.

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.

Can pediatric intussusception be cured?

Once intussusception occurs, only a small portion of the small intestinal intussusception can reduce on its own. Those occurring in the colon or where re-intussusception occurs generally cannot reduce spontaneously and require enema therapy or surgical treatment. Enema therapy refers to cases where the intussusception occurs within forty-eight hours, the overall condition is good, there is no abdominal distension, no obvious dehydration or electrolyte disorders, and air or barium enema can be used. If the condition persists for more than forty-eight hours, the overall condition is poor, with symptoms such as dehydration, lethargy, high fever, shock, significant abdominal distension, signs of peritoneal irritation, multiple occurrences of intussusception, prior organic changes, or situations requiring surgical treatment for small bowel 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.

Can intussusception in children cause fever?

In the early stages of intussusception, the child generally remains in good condition, with normal body temperature and no symptoms of systemic poisoning. As the disease progresses and worsens, complications such as intestinal necrosis or peritonitis may develop, leading to deterioration of the overall condition. At this point, severe dehydration, high fever, lethargy, coma, and shock, among other symptoms of poisoning, can occur. Therefore, fever can indeed appear in the later stages of intussusception.

Is intussusception in children serious?

Intussusception is a life-threatening emergency, and its reduction is an urgent treatment measure that should be performed immediately once diagnosed. In the early stages, the child generally appears healthy, with normal body temperature and no obvious symptoms of poisoning. However, as the condition progresses and the duration of the intussusception increases, it can lead to intestinal necrosis or peritonitis, causing a deterioration in the overall condition. Commonly, severe dehydration, high fever, coma, shock, and other serious symptoms of poisoning may occur.
