The scientific name for “small bowel gas”, also called “bulge”, is hernia. The majority of hernias occur in the abdominal wall and are caused by the protrusion of organs such as the small intestine from the abdominal cavity outside the abdominal wall through this weak or defective area. There are many types of hernias, including those located between the lower abdomen and the base of the thighs called “inguinal hernias”, those located in the navel called “umbilical hernias”, those located in the middle of the upper abdomen called “white line hernias”, and There is also “incisional hernia” which occurs when the incision is not healed properly after abdominal surgery. Hernia is a common and frequent disease that can occur in small babies to old people, in both men and women, and in both weak and healthy people. Relatively speaking, inguinal hernia in elderly men and umbilical hernia in middle-aged and elderly obese women are the most common. There are both congenital and acquired causes of hernias, such as chronic cough, constipation, prostate hypertrophy or cirrhotic ascites, which make them more likely to occur. The main manifestation of hernia is a lump protruding from the abdominal wall when standing, which becomes more obvious when exerting force or holding the breath, and can disappear on its own after lying down in the early stage. If the above symptoms occur, the possibility of hernia should be considered and a hospital visit should be made in time to clarify the diagnosis. Surgery is the only effective way to cure a hernia, and it should be performed as early as possible. It is understandable that people have a fear of surgery, but a look at the progression and complications of hernias will show the benefits of early surgery. First, the hernia will only get bigger and bigger and is unlikely to maintain the status quo or shrink. A hernia is like a hole in a garment, it will only get bigger and bigger, and the bigger it is, the harder it is to mend. We have come across many patients who, because of fear of surgery, did not come to surgery until their inguinal hernia was as big as a ball in the scrotum and seriously affected their lives. Second, there is also the possibility of acute complications if the hernia is not operated in time. The protrusion of more intestinal segments outside the body due to a particular cough, bowel screen and other exertion causes failure to return into the abdominal cavity, leading to acute intestinal obstruction, causing severe pain, which if not treated in time can eventually lead to adverse consequences such as intestinal necrosis, perforation and even death from peritonitis. Usually, hernia is a minor surgical procedure, which is not complicated and is very safe and reliable. Delaying surgery after diagnosis only increases the difficulty of surgery and the risk of emergency, which is not worth the loss. As mentioned earlier, a hernia is like a hole in a garment, so hernia surgery is actually a process of “patching” the hole. The traditional surgical method is direct patching, just like sewing up a hole in a garment with thread, and since the edges of the defect are sewn together directly, the postoperative pulling pain is obvious, the patient’s recovery is slow, and the recurrence rate of hernia is over 10%. In recent years, with the development of material science, polymer materials compatible with human tissues have been applied, which we image as “patch”, which is commonly known as adding a padding to the hole in the clothes. In addition, the patch can also stimulate the autologous tissue to form a solid barrier structure, so the repair effect is good, the recurrence rate is low, the postoperative pain and other complications occur less, and the patient recovers quickly after surgery, so the patch repair method has gradually replaced the traditional surgical method.
