intussusception
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.
How to treat intussusception in infants
The treatment of intussusception mainly includes non-surgical and surgical methods. The non-surgical method involves enema treatment. Within 48 hours of the onset of intussusception, if the overall condition is good, there is no abdominal distension, no apparent dehydration, and no electrolyte disorders, ultrasound-guided hydrostatic enema, air enema, or barium enema can be performed. If the intussusception lasts more than 48 to 72 hours, or if the duration is shorter but the condition is severe, with intestinal necrosis or perforation, surgical treatment is required.
Does intussusception require a CT scan?
Intussusception is commonly diagnosed through routine abdominal ultrasound examinations, which have a positive rate of over 90%. In the ultrasound, the transverse section of the intussusception can show concentric circles or target ring-shaped mass images, and the longitudinal section may reveal the sleeve sign. Additionally, a barium enema can be employed, along with X-ray imaging. Under X-ray, the lead point of intussusception appears as a mass shadow, and air enema reduction treatment can be performed concurrently. Generally, CT is not used as a routine diagnostic tool.
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.
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.
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.
How to treat intussusception in children?
Intussusception is a life-threatening emergency that requires urgent reduction once diagnosed. Reduction methods include non-surgical and surgical therapies. Within forty-eight hours of intussusception, if the overall condition is good, there is no abdominal distension, and no significant dehydration or electrolyte imbalance, reduction can be attempted under ultrasound guidance using hydrostatic enema, air enema, or barium enema. If the intussusception has lasted beyond forty-eight to seventy-two hours, or if there is severe abdominal distention, intestinal necrosis, or perforation, surgical treatment is necessary.
Can intussusception heal itself?
Once intestinal intussusception occurs, only a small part can be spontaneously reduced. In most cases, urgent reduction treatment is required, including non-surgical and surgical treatments. Non-surgical treatment mainly involves enema therapy. Within 48 hours of the intussusception, if the overall condition is good, the abdomen is not distended, and there are no obvious signs of dehydration or electrolyte imbalance, barium enema treatment can be applied. If the duration of the intussusception exceeds 48 to 72 hours, or if the condition is severe with intestinal necrosis or perforation, surgical treatment is necessary.
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.
What department should I go to for infant intussusception?
Intussusception often occurs in infants and young children, mainly presenting with vomiting, abdominal pain, and bloody stools. The first department usually visited is the emergency pediatrics. If intussusception is confirmed, treatment may involve surgery or non-surgical reduction. Therefore, after confirming intussusception, the patient needs to be transferred to pediatric surgery or general surgery for inpatient treatment.
