Intussusception can cause symptoms such as abdominal pain and vomiting. When intussusception has not been reduced, it is not recommended to drink water or eat food, because the vomit can lead to choking. It can also cause vomit to enter the trachea, leading to aspiration pneumonia, suffocation, and other serious symptoms. Therefore, generally after the intussusception is reduced and there is anal exhaust, proving that the intestines are unobstructed, then drinking water is permitted.

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 to check for intussusception?

Intussusception is primarily diagnosed based on medical history, symptoms, physical signs, and auxiliary examinations. Medical history is mainly gathered by asking the parents, which is very important. Physical signs involve the doctor performing an abdominal palpation, where generally a mass can be felt on the abdominal wall. Auxiliary examinations usually include abdominal ultrasonography and upright abdominal plain films. For more complicated cases or when the location is unique and difficult to detect, a CT scan of the intestines may be performed to make the final diagnosis.

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.

Caused by infantile intussusception

Intussusception is divided into primary and secondary types, with 95% being primary cases, most commonly seen in infants and young children. This is due to the fact that the mesentery of the ileocecal part in infants and young children is not yet fully fixed and has a greater degree of mobility, which are structural factors that facilitate the occurrence of intussusception. The remaining 5% are secondary cases generally occurring in older children, where the affected intestines often have a clear organic cause, such as a Meckel's diverticulum turning into the ileal lumen, serving as the starting point for intussusception. Other causes like intestinal polyps, tumors, duplications, or abdominal purpura can cause the intestinal wall to swell and thicken, which can also trigger intussusception.

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.
