It is clinically manifested as a round hernia that protrudes from the umbilical ring and disappears when standing, coughing or straining. Clinically, there are two types of umbilical hernia: pediatric hernia and adult hernia. The former is more common than the latter. Pediatric umbilical hernias are mostly present at birth due to incomplete development of the umbilical ring; adult umbilical hernias are more common in obese people with weak abdominal walls, middle-aged and elderly people and menstruating mothers, as well as in patients with chronic diseases with increased intra-abdominal pressure, such as patients with cirrhosis of the liver and ascites. With the growth and development of children, umbilical hernia in children can heal on its own within 2 years of age, so it is not necessary to operate on infants and children within 2 years of age, but if the umbilical hernia does not disappear or shrink after 2 years of age, then surgery is needed. In adults, umbilical hernia is different and cannot heal on its own. However, many middle-aged and elderly patients with umbilical hernia do not pay attention to this disease. What are the reasons for this lack of attention? 1. Umbilical hernia is relatively small, painless and sometimes not even noticed, so many people do not take it seriously. 2. There is not enough knowledge about umbilical hernia, and it is considered as a minor disease of no importance. 3. Some people take umbilical hernia seriously, but after consultation, they find that umbilical hernia has to be treated surgically and in many cases the umbilical orifice has to be removed, so they are reluctant to operate because they are afraid of surgery or cannot accept the treatment of removing the umbilical orifice. However, in fact, because the hernia ring of adult umbilical hernia is tougher, less elastic and non-expandable, it is easy for the contents of the umbilical hernia to protrude and then not return, which is also known as medical entrapment. It is then no longer a “soft egg”, but a sudden increase in size of the mass and severe pain, which can later cause intestinal obstruction and intestinal necrosis, and even life-threatening in severe cases. Imagine, once the contents of the umbilical hernia (intestine or large omentum) are stuck in the small umbilical ring, the consequences of ischemia and necrosis are unimaginable, so adults should be operated as soon as possible once the umbilical hernia appears. So how should the surgery for umbilical hernia be done? Is it true that there is no navel after surgery, as many people say? In the past, the umbilical hole was removed while the surgery was being performed, which is one of the reasons why more patients are reluctant to undergo surgery. During open surgery, an arc-shaped incision is made around the umbilicus, and care is taken to avoid damaging the umbilicus and to preserve the blood supply to the umbilicus, thus reducing postoperative complications such as ischemic necrosis of the umbilicus and preserving the umbilicus intact; during laparoscopic surgery, the location of the hole is chosen on the lateral abdominal wall, so that the umbilicus is not touched at all, thus better protecting the umbilicus. The procedure of preserving the umbilicus has been well received by many patients and is more acceptable to them. The procedure also applies a patch, thus avoiding recurrence. A small “soft shell egg” can cause big problems, so I hope we can pay attention to it. Before “sheep” is “dead”, first “jail” “mend” good, why not?
