Most of them have large mesenteric lymph nodes, some as large as 25 mm in diameter, which often makes parents very nervous. This often makes parents very nervous. Some children go on cephalosporin antibiotics because of this. What exactly is going on here? Is it necessary to take medication? Is it related to your child’s abdominal pain? Listen to what pediatricians have to say. Pediatricians want to tell you that lymph nodes have nothing to do with your child’s abdominal pain, so don’t give your child anti-inflammatory drugs because of this. This is because assuming a child comes in for an ultrasound when their stomach doesn’t hurt, they will find that the lymph node is still there, and it has always been there whether your stomach hurts or not. Some children who come back from 1 week of antibiotics to unrequested review find that there is no change in the lymph node and are often quite critical of the doctor’s treatment if the medication was prescribed by the doctor. If there is no relationship, why does the doctor want to check the ultrasound? The doctor ordered the ultrasound to rule out a pediatric emergency called ‘intussusception’ and also to get a general idea of the entire abdominal cavity. Why is this lymph node present? This is because the child is in the lymphatic active stage, what is the lymph node, it is a small house of lymphocytes, lymphocytes more house will be big, otherwise can not live ah, huh. If you feel your child’s neck, most children will have some swollen bumps on their neck when they have a cold, and these are lymph nodes. So, don’t worry, it means your child’s immune function is normal. Some doctors say it is mesenteric lymphadenitis, how can I explain this? One thing to note is that for children with abdominal pain many doctors will give the diagnosis: mesenteric lymphadenitis, which looks reasonable, the child has stomach pain and enlarged lymph nodes on ultrasound, which seems to fit, and this diagnosis also fits the parents’ psychology, but this diagnosis is really wrong, or at least too broad. Let’s look at what mesenteric lymphadenitis is. Mesenteric lymphadenitis, like inflammation of lymph nodes in other areas, is a local infection that spreads to the surrounding lymph nodes, not an inflammation of the lymph nodes that is swollen. For example, a child with abscessed tonsils will have swollen lymph nodes in the neck, which are the result of immune mobilization in the body to remove bacteria. If the lymph nodes are then red, swollen, and hot, it means that bacteria have infected the lymph nodes, and this is lymphadenitis. Therefore, mesenteric lymphadenitis will have abdominal pain, but most of it is constant pain, not relieved after the stool, there must be a high fever, because it is caused by inflammation? There is pressure pain or even rebound pain in the abdomen, especially like acute appendicitis, only the pressure pain point is not fixed like appendicitis, the right lower abdomen, mostly after the cold. The majority of abdominal pain in children is caused by intestinal cramps, not mesenteric lymphadenitis. Well, the purpose of all this is to make sure that you don’t get nervous about a large lymph node in the abdominal cavity found by ultrasound, which doesn’t require special treatment, let alone the use of antibiotics. If the lymph nodes are particularly large, it is important to review them in the context of the child’s condition. The frequent paroxysmal abdominal pain in children is mostly intestinal spasm, which is related to the child’s diet and living habits, and does not require medication.
