When children are small, they mainly communicate with the outside world through crying because they cannot speak. There are many reasons for crying, such as hunger, stinky, or uncomfortable clothes, and sometimes parents are at a loss as to why their child is crying for no good reason. Most crying is normal, doesn’t last long, and has no other abnormalities that can be relieved by reassurance. However, some children cry because of pain caused by illnesses, even some more acute ones, and that requires care, such as the stuck hernia mentioned earlier. In addition, when the child appears paroxysmal crying for no reason, crying for more than 10 minutes, quiet a few minutes, and then a burst of crying, repeatedly continue, then we should be alert to another disease: intussusception. Intussusception is the intestine into the adjacent intestine, is stuck can not get out, the main risk is that over time, stuck in the inside of the intestine will be necrosis, leading to serious consequences. Intussusception is one of the three major emergencies in pediatric general surgery, which means that the incidence is still quite high. Since it is an emergency, the main job of dealing with it is left to the doctor, and all the parents do is to find the child’s problem early and think of the disease, and then send it to the hospital in time. Which children should be alerted to intussusception? The best age for intussusception is from 4 months to 10 months, and the fat children in this age group, especially male fat children, should be especially alert. 2 years old and above, intussusception decreases year by year, and newborns and 5 years old and above should be careful if it is caused by something growing on the intestine, that is, secondary intussusception like the child in the previous article. In addition to the characteristic paroxysmal crying, the most common manifestations of intussusception are vomiting and “jam-like” stools, which are caused by the intestines being stuck, and these are the typical symptoms. The doctor can determine this based on these symptoms, plus feeling the belly and feeling a long bag, but some children cry a lot and hold their belly, or the child is too fat and the belly is bloated, so it is not so easy to feel, so you need to rely on ultrasound to determine. Some children have atypical behavior, and some parents feel that the child’s face is white and painful, and they feel that something is wrong and send the child to the hospital, and the result is confirmed to be intussusception. A colleague once saw a child who threw up after falling out of bed, thinking it was a concussion, and didn’t feel anything abnormal in the stomach, but felt something was wrong and did an ultrasound, which turned out to be intussusception, making it impossible to prevent. As long as the child has had an intussusception, parents are very vigilant, as soon as they find that the child is not right to the hospital, so there is basically no delay, dragging to intestinal necrosis, shock is often the first onset. The doctor is actually the same, after a missed diagnosis of intussusception, the billing rate of abdominal ultrasound will also rise rapidly, this is the reaction of increased vigilance. It is not difficult to treat intussusception after it is clearly diagnosed, through enemas, that is, pumping gas or water into the buttocks, relying on the pressure of gas or water to flush out the intestines that are drilled in, although in a few cases intestinal perforation will occur, but more than 90% can be cured in this way, and most of them will not recur after being cured. If the intestine is stuck tightly and can’t be flushed out, surgery is the only way to avoid re-infarction. Parents of children who have had intussusception feel very scared and want to know how to prevent it. Unfortunately, apart from secondary intussusception caused by intestinal growth, the cause of intussusception is not very clear at present. Some think it may be related to dietary changes, some think it is related to neurological disorders, but there is no very definite evidence. What is clearer is that some enterovirus and respiratory virus infections can trigger intussusception, for example, rotavirus vaccine can increase the risk of intussusception, so although it is difficult to prevent, it is important to try to do a good job with your child’s personal hygiene.
