The first thing you need to do is to take a shower and inadvertently feel a soft pimple, the size of a peanut rice, on the midline of your upper abdomen, without pain or itching. The doctor told him it was a lipoma, benign, and that it would be fine after the surgery. The bumps he felt this time felt similar to the last time, so he thought it was still a lipoma. The surgeon felt it and didn’t say anything, but prescribed an ultrasound for Uncle Xu to do. After the ultrasound doctor looked at the report and told Uncle Xu that this situation requires hospitalization for surgery, Uncle Xu is not happy, just a lipoma outpatient do not finish it, what hospital to live in, must be this doctor swindle me. The doctor saw the uncle’s mood and said with a smile: what you have this time is not the last lipoma, but a disease called white line hernia, which is also a kind of small intestine gas. He said that he was strong and healthy and that he was fine down there, so why would he have small intestine gas in the stomach? The doctor explained patiently to Uncle Xu that his uncle had the most common type of small intestine gas – inguinal hernia, while white line hernia is not very common in clinical practice. We have all seen the eight abdominal muscles on the belly of bodybuilders. The middle of the abdominal muscles on both sides, where the midline of the abdomen is located, is not a muscle but a tendon-like tissue, anatomically known as the white line of the abdomen. Under normal circumstances the white line of the abdomen is very dense, except for the widening of the place in the belly button, the white line of the abdomen should be no holes and gaps above. However, in some cases, the white line becomes weak or defective at some point during the developmental growth process and a white line hernia is formed. Most of the hernia is formed and what falls out is the small intestine in the stomach, hence the common name “small intestine gas”. In most white line hernias, the defect is so small that the intestine cannot escape, but only the extraperitoneal fat in front of the peritoneum behind the white line comes out of the hernia hole, so the feeling is often not much different from a lipoma. If the doctor is not careful or inexperienced and does not do ultrasound for further examination, it is easy to misdiagnose it as a lipoma, and only when the surgery is performed is a defect found in the white line below the fat mass. Only after listening to the doctor’s detailed explanation did it dawn on Uncle Xu that he had met a good and experienced doctor. The doctor told him that white line hernia is a minor disease among hernia and it is only a minor surgery for hernia and abdominal wall surgeons, and that finding the defect and repairing it can cure it. Uncle Xu was quickly admitted to the hospital for surgery and was discharged two days after the surgery. The bumps on the abdominal wall are not necessarily fatty tumors, and in most cases, they are not what you think they are.
