Clinical manifestations of intussusception include: firstly, abdominal pain, which is paroxysmal, regular, and characterized by sudden episodes of colicky pain. The child may cry, appear restless, draw knees to the abdomen, have a pale face, and experience pain that lasts for several minutes or longer. The pain subsides, and the child may fall asleep quietly, but the pain typically recurs at intervals of ten to twenty minutes. Secondly, vomiting is an early symptom, initially reflexive and containing curds and food residue, later possibly including bile. Thirdly, bloody stools are an important symptom, with about 85% of cases passing jelly-like mucoid bloody stools within six to twelve hours after onset. Fourthly, an abdominal mass is often located in the upper right abdomen below the costal margin, where a slightly prominent intussusception mass can be felt. In terms of systemic symptoms, the general condition is good in the early stages, with no symptoms of systemic poisoning. As the disease progresses, the condition worsens, and complications such as intestinal necrosis or peritonitis may develop, leading to deterioration of systemic symptoms and possibly resulting in dehydration, high fever, coma, shock, and other toxic symptoms. Treatment methods include both surgical and non-surgical treatments.

Is infant intussusception dangerous?

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.

Symptoms of intussusception in infants

The clinical manifestations of intussusception mainly include abdominal pain, vomiting, bloody stools, and an abdominal mass. The abdominal pain is often spasmodic and regular, manifesting as sudden severe colicky pain. The child appears to be crying and restless, with knees drawn up to the abdomen, pale complexion, and the pain lasts for several minutes or longer but lessens after; it recurs every ten to twenty minutes, accompanied by intestinal movements. Vomiting is an early clinical symptom, initially consisting of milk curds or food residue, and later may include bile and fecal-like liquid. Bloody stool is an important symptom, appearing within the first few hours; initially, the stools can be normal, with about 85% of cases excreting jam-like mucoid bloody stools within six to twelve hours of onset. The abdominal mass is often located in the upper right abdomen below the costal margin, where a slight, tender mass can be palpated.

Infant intussusception symptoms

Intussusception clinically presents with abdominal pain, which occurs in fits and starts and has a regular pattern. This manifests as sudden spasmodic colic; the child cries and is restless, drawing the knees up to the belly and turning pale. The pain lasts for several minutes or longer, then eases off, allowing the child to fall asleep quietly. These episodes recur every 10 to 20 minutes as intestinal movements provoke further attacks. Vomiting occurs, initially consisting of curdled milk or food residues and later containing bile-stained, feculent fluid. Moreover, blood in stools is an important symptom. Symptomatically, stools may appear normal for a few hours, but within six to twelve hours, 85% of affected children might pass jelly-like mucus blood stools. A palpable lump can be detected in the upper right abdomen, indicative of the point of intussusception. As for general symptoms, the child may appear well early on, but as the condition worsens, intestinal necrosis or peritonitis may occur, leading to severe dehydration, high fever, lethargy, coma, shock, and other signs of systemic toxicity.

Does intussusception cause diarrhea?

Intussusception is a common surgical condition in infants and young children, characterized primarily by symptoms such as abdominal pain, crying, abdominal distension, the passage of jelly-like stools, and vomiting. Some children may also experience diarrhea and frequent passage of jelly-like stools, where the symptoms of intussusception may not be particularly noticeable, leading parents to possibly overlook them. Therefore, if a child has diarrhea accompanied by jelly-like stools, it is crucial to take the child to the hospital for a consultation and an ultrasound to confirm whether it is caused by intussusception. If left untreated for a long time, it can lead to ischemic necrosis of the intestinal mucosa, necessitating surgical treatment.

Can intussusception in the elderly be cured?

Intussusception in the elderly rarely heals on its own, and the likelihood of recovery without treatment is very small. This is because the causes of intestinal issues in the elderly are primarily benign, often due to cirrhosis or other reasons. Furthermore, intussusception may also occur due to tumors, which generally require surgical treatment. It is advised that if diagnosed with intussusception, it is best to undergo surgical treatment at a hospital to prevent recurrence. If it is due to a tumor, there is a risk of it becoming malignant and metastasizing.
