After a few “fine steps” in the hospital compound in the middle of the night, the storyteller was finally able to sit down on a chair and think about life – from the ward to the emergency room. The number of steps from the ward to the emergency room has not reached 10,000? The book picks up where the last one left off, and I feel deeply uneasy that my stomach is gradually running out of stock – what else can I say next? I’m not sure I’m going to be able to get a good deal on this. Ovarian duct development abnormal – the storyteller is in a great state of mind, can’t help but “look up to the sky and laugh out the door, my generation …… security beaten into a dog, 555~~~ OK, OK, everyone see if my tongue is still there? Still in it, in good. Ahem, let’s start talking about this: dare to ask the guests, know the yolk tube is what is sacred? …… ah? You really know it? The first thing you need to do is to go back to Mars! In the embryonic period, the proto-intestine and the yolk sac are connected, this channel slowly becomes thinner as the embryo develops and is called the “yolk tube”, as the name implies, is the “tube connecting the yolk sac” it…. …you ask what is “proto-intestine” and “yolk sac”? emm…… this is not the point, let’s look at the yolk sac …… No, the yolk tube …… You can interpret the yolk tube as the tube between the navel and the intestinal tube. The yolk tube slowly shrinks and atrophies during the 5th to 6th week of embryonic life, and soon after the baby is born, it degenerates and disappears completely – so to speak. … but! But! If this guy does not go, it will lead to a variety of abnormalities, can be said to be endless poison First of all, if the yolk tube is mostly atretic, but there are residues outside the baby’s belly button, the formation of the umbilical velvet. It’s not antler, it’s umbilical velvet! Also known as umbilical polyps, the baby’s belly button seems to have grown a small bright red meat ball, the surface is wet, and from time to time secrete a little red thin liquid, so that the baby’s parents, baby mothers heartache. The umbilical cord velvet is simple to deal with, electrocautery or excision is OK. Secondly, if the yolk tube remains a little more in the baby’s umbilicus and leaves a “small pit” in the deep part, then it forms the umbilical sinus. The umbilical sinus looks very similar to the umbilical velvet, it also looks like a round mucous membrane bump, but there is a small hole in the center with a few millimeters of blind tubes that secrete mucus outward, often making the baby’s little belly button vile and infected, which is more hateful than the “umbilical velvet”. The doctor needs to control the infection and then the knife – to remove it completely. Once again, if the yolk tube is not closed, it is connected between the baby’s belly button and the intestinal tube, becoming an “umbilical fistula”. Unlike the umbilical sinus, there is a bright red mucous membrane and a small hole in the center of the baby’s belly button, which can expel mucus and gas, and even feces. In this case, it is more problematic to remove the navel, the fistula (the tube that connects the navel to the intestine) and the connected part of the small intestine together, and then anastomose the two ends of the removed part of the small intestine, and finally, you have to do the umbilical ring reconstruction. Look, is this umbilical fistula full of evil? Let our doctors get rid of it before it is too late! Fourth, the yolk duct cyst, relatively rare, it is because the ends of the yolk duct are closed, but the middle section did not grow, maintaining the original lumen of the yolk duct, the fluid secreted in the lumen gathered, “suffocated” into a cyst. The yolk duct cysts are generally more “peaceful” and do not affect the baby, and are often discovered inadvertently during a physical examination – a well-defined cyst below the baby’s belly button that can move. The treatment of yolk duct cysts is relatively simple and can be removed. Fifth, Merkel’s diverticulum. This is a part of the yolk duct that does not close against the intestine, leaving a “small bump” on the wall of the ileum, called a “diverticulum” (by the way, are you sure you know how to pronounce the word “diverticulum”? The diverticulum may have gastric mucosal tissue remaining in the diverticulum lining, which can secrete gastric acid, and as it does so, the nearby intestinal mucosa is “secreted” into an ulcer. This “ulcer”, it is inevitable bleeding, so the child will appear anemia, bloody stools and other symptoms, and in some cases, bleeding is more serious, may also lead to hemorrhagic shock! In addition to bleeding, Merkel diverticulum this guy may also lead to intestinal obstruction (intestine twisted leading to not pass), diverticulitis (that is, Merkel diverticulum themselves inflammation), diverticulum perforation (that is, “ulcers” serious intestinal tube wall to corrode broken), evil ah, the storyteller and almost can not go on, hurry up, quickly let the doctors put it The sixth, the umbilical cord. The yolk tube “waved a sleeve” or left a cloud – the yolk tube atresia formed a cord, left between the umbilicus and the intestinal canal or hepatic portal. In a few cases, the intestinal canal rotates around the cord and may form an intestinal obstruction, at which point symptoms may occur. Once discovered, the umbilical cord should also be removed as soon as possible to eliminate future problems.
