Intussusception is a process in which a segment of the intestine becomes lodged in the lumen of the adjacent intestine, causing intestinal obstruction. There are two types of intussusception: primary intussusception, which usually begins at the ileo-colonic junction and is common in infants and children. Secondary intussusception (jejuno-jejunal, jejuno-ileal, ileo-ileal), which occurs in older children. The latter is associated with specific clinical signs (e.g., allergic purpura, cystic fibrosis, hematologic malignancy) or may be secondary to an inciting point (polyps or terminal ileal lymph node hyperplasia); it occasionally occurs postoperatively (after extensive retroperitoneal lymphatic dissection). Intussusception is a common condition in babies up to 2 years of age, with the highest incidence in infants up to 10 months of age. Intussusception is when a segment of the intestine becomes lodged in the lumen of the intestine to which it is attached. The intestinal peristalsis pushes the intestinal segment forward and the mesentery is stretched, causing intense pain in the sheath of the intussusception. The pain stops after a burst of peristalsis until the next burst of peristalsis triggers the pain again. As a result, the child will experience bouts of crying, every 15-20 minutes. At the same time, there are symptoms such as vomiting and jam-like bloody stools, the baby is not in good spirits, urine output is reduced, and salami-like masses can be felt in the abdomen. A. Causes There are many causes of intussusception in babies. Zhou Wei analysis, infants and young children originally intestinal tract is not as stable as adults, the change of season, weather changes may lead to irregular intestinal peristalsis; intestinal virus infection may also affect the normal peristalsis of the intestinal tube; change of milk powder, add supplementary food is also prone to intestinal peristalsis dysfunction; may also be the infancy ileocecal valve excessive hypertrophy, etc.. Symptoms 1. abdominal pain Since children are young, they cannot complain of abdominal pain, so they often show sudden paroxysmal crying, legs flexed to the abdomen, pale face, and will have another attack after a few minutes. 2. Vomiting The child will vomit soon after the onset of abdominal pain. The vomit may start with milk, milk lumps or food remnants, followed by grass-green bile, or even fecal-smelling liquid in severe cases. 3, blood in the stool There may be 1-2 normal stools at the first onset, but after a few hours, a dark red blood stool or a mixture of blood and mucus, called jam-like stool, may be excreted. 4. Abdominal masses are usually seen in the early stages of the disease. When the abdominal pain is relieved and the abdominal muscles are relaxed, parents can feel a mass like a salami or banana in the right upper abdomen of the child. The lump is slightly elastic, with a smooth surface and slightly movable, which is the most valuable sign for diagnosing intussusception in children. There are two types of treatment for intussusception: non-surgical and surgical. In the non-surgical treatment there are air enema, B ultrasound under the water pressure enema and other reset therapy, compared to X-ray fluoroscopy under the air enema, B ultrasound no radiation which will give more parents peace of mind. If the enema cannot be reset, then surgery is required. The key to treating pediatric intussusception is early detection. If intussusception does not occur in time, the baby has to suffer a lot of pain. And, the onset of more than 12 hours, may lead to intestinal obstruction, intestinal necrosis, shock and other serious consequences. If the onset of intestinal necrosis is suspected after 24 to 48 hours, surgical treatment is required. In order to avoid inducing intussusception in babies, daily care should be paid attention to. In order to avoid viral infections, it is important to take your baby to public places with fewer people during the change of season; let your baby eat less food that is not digested, and pay attention to the hygiene and careful disinfection of your baby’s tableware; intestinal peristalsis is clockwise, do not massage your baby’s abdomen counterclockwise to avoid obstructing normal intestinal peristalsis. In addition, advocate breastfeeding, scientific addition of complementary foods. It is recommended that babies add complementary foods after 6 months of age. Each time you add a new complementary food, the number should also be added slowly from little to much, seafood and other foods that can easily induce allergies is best not to feed your baby too early.
