“Victoria’s Secret” should not be unfamiliar to many people. Yes, this internationally renowned lingerie brand attracts countless eyeballs with its annual lingerie show. The super models at the show are the focus of attention. Karolina Kulkova Karolina Kurkova is one of them. The world’s 15 highest-paid models in one of the body proportion is perfect, but the most striking is her “belly button”. (Supermodel without a belly button) Belly button, commonly known as the navel, is present in everyone. Everyone knows that it is the scar left by the umbilical cord after the baby is born. And Karolina B. Kulkova’s “belly button” is not a navel, just a depression. Could it be that she is the reincarnation of Eve? (Normal belly button formation) It turns out that she was once a child with “abdominal cleft”, not long after the birth of the surgery. The surgery was successful and healed well afterwards. As her body grew up, she could barely see the surgical scars, but was left with this special belly button. So what is ventral fissure? Umbilical hernia, umbilical bulge, and ventral fissure are the three most common congenital umbilical abnormalities that babies are born with. (Umbilical hernia diagram) Umbilical hernia is among the most common pediatric malformations. The baby has an intact belly button with the internal organs of the stomach (mainly the greater omentum) protruding through the defective umbilical ring with intact skin on the surface. This is what happens: (Pediatric umbilical hernia) An umbilical bulge is when the internal organs (mainly the intestines) of the baby’s stomach run into the umbilical cord with a transparent membrane wrapped around the surface. Such a child does not have a complete belly button structure. (Diagram of abdominal fissure and umbilical bulge) Abdominal fissure is a split in the abdominal wall next to the umbilical cord, and the internal organs (mainly intestines) of the belly escape and are completely exposed. All three malformations are the domain of hernia and abdominal wall surgery. Most umbilical hernias in babies heal on their own by the age of 3 years and can be monitored with care. Only very large, symptomatic children, those who develop complications, or those who do not heal after the age of 4 years require surgical intervention. Most adult umbilical hernias are acquired and many are external manifestations of intra-abdominal disease. They do not heal on their own and are prone to impaction. Therefore, adult umbilical hernia requires prompt diagnosis and treatment. Ventral fissures and umbilical bulges require early surgical treatment after birth, are often associated with severe other malformations and complications, and have a certain mortality rate.
