Pediatric intussusception can be considered a common disease in pediatric outpatient emergencies that requires the attention of medical and surgical surgeons at all times. The common age of high incidence in the book is from April to October, but in the clinical process we often encounter intussusceptions in younger or older children, and sometimes unexpectedly, so early ultrasound is safe and necessary for suspected cases. Especially for those who have had intestinal condom, we should be more careful about the recurrent condom, and the symptoms of recurrent condom are not as typical as the book says, especially in older children, the symptoms of abdominal pain and physical examination are not heavy, but once checked, it may be a condom. The pattern of re-circumcision varies from child to child, with intervals of several days, months, and years, and some even within an hour. There are also children who do not have a condom for the rest of their lives, or who have a condom only once. There are sets of 20 times, from small to large sets. Generally speaking, the incidence of intestinal condyloma decreases with age, except for secondary condyloma, which should be considered if the older child has repeated condyloma. In principle, the diagnosis and air enema should be made as early as possible to avoid prolonged intestinal ischemic and hypoxic necrosis caused by prolonged intussusception, delaying the time of air enucleation, and after successful air enucleation, fasting for an appropriate short period of time and The application of antispasmodics (654-2) can somewhat alleviate the occurrence of re-intussusception, but not necessarily, some people are repeatedly set, and the frequency is particularly high, I have seen a child is 1 day set 3 times, so the family should have a number in mind, once set there is the possibility of re-set multiple sets.
