Mr. Wu, who is always on official assignment in Africa, found his belly button protruding a small, painless bulge six months ago, and sometimes it didn’t bother Mr. Wu at first. The irregular work and rest for many years made Mr. Wu in a subhealthy state, at the age of 40, he already had coronary heart disease and diabetes, and this gradually increasing bulge also made him anxious, “Could this small bulge be a tumor?” Once he returned home, Mr. Wu came to the hospital and learned after a simple examination that he had an umbilical hernia. So is this disease serious? Umbilical hernia is a small intestinal gas protruding from the umbilical ring, manifested as a bulge in the belly button when standing as well as doing strenuous activities, mostly seen in middle-aged and elderly menstruating women with weak abdominal wall and obese men. It is medically defined as an extra-abdominal hernia in which the abdominal contents (e.g., greater omentum, intestinal canal) protrude from the weak area of the umbilicus. While pediatric umbilical hernias tend to heal on their own within 2 years of age, adult umbilical hernias are not likely to heal on their own, but because they are mostly asymptomatic, they are overlooked by many patients as a minor and insignificant condition, or even mistaken for a lipoma. In fact, for adult umbilical hernia, this small bulge is like a time bomb, because the hernia ring of adult umbilical hernia is smaller and the edges are tougher, so it is easy for the hernia contents to get stuck and cannot be returned, which is medically known as intussusception, manifested by the sudden enlargement and toughness of the originally soft bulge, accompanied by severe abdominal pain, which may even cause intestinal obstruction and intestinal perforation, and in serious cases, endanger life. Therefore, once diagnosed, all should be operated as soon as possible. In the past, the belly button was often removed to repair the hernia ring, so many patients resisted such surgery. However, with the rapid development of minimally invasive surgery and hernia repair materials, modern medicine has been able to repair the defect below the belly button with a patch made of synthetic material through the laparoscopic technique of making three “eyes” in the lateral abdominal wall, which preserves the belly button with little trauma and quick recovery. The procedure is less invasive, faster recovery, no stitching and no scarring. Eventually, Mr. Wu decided to use his short vacation to complete the minimally invasive surgery in the hospital, the night after the operation on the ground, 1 week after the resumption of normal work. Of course, there are certain indications for minimally invasive surgery. For patients with umbilical hernia who have very poor cardiopulmonary function and cannot tolerate general anesthesia, we can still complete the repair through a small incision with a good “patch” under local anesthesia. Therefore, early diagnosis and early treatment are essential to prevent the “bulge” from becoming a big problem!
