Intussusception in children is a common surgical condition. The treatment approach depends on the severity of the child's clinical symptoms. If the intestines have not been telescoped for long, and the intestinal mucosa has not suffered ischemic necrosis, and if the clinical symptoms are mild, air enema can be used to relieve the intussusception without the need for surgery. However, if the clinical symptoms are severe and necrosis has been prolonged, meaning the intestinal mucosa has reached a state of ischemia and necrosis that is irreparable, surgical treatment in a surgical setting is definitely required. Whether surgery or air enema is needed should be decided based on the actual color ultrasound results and a comprehensive diagnosis by the clinician.

Can intussusception pass gas?

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.

Is intussusception in children serious?

Intussusception is a life-threatening emergency, and its reduction is an urgent medical treatment that must be performed immediately once diagnosed. Generally, in the early stages of intussusception, the general condition is still good, with normal body temperature and no symptoms of systemic toxicity. As time progresses, the condition worsens, and there may be necrosis of the intestines or peritonitis, with overall health deteriorating. Common severe symptoms include dehydration, high fever, lethargy, coma, and shock from toxicity.

Intestinal intussusception described by ultrasound.

The appearance of intussusception under ultrasound shows concentric or target ring-shaped mass images on a transverse section scan, and a sleeve sign on a longitudinal section scan. For an ultrasound-guided hydrostatic reduction, a balloon is inserted through the anus and inflated, connecting a T-tube to a Foley catheter with a side tube connected to a sphygmomanometer to monitor water pressure. Isotonic saline at a temperature of thirty to forty degrees is injected, and the target ring-shaped mass image can be seen retracting to the ileocecal region. The disappearance of the concentric circles or sleeve sign under ultrasound indicates the completion of this therapeutic diagnosis.

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.

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.
