A hernia is a part of the body’s tissue or organ that leaves its original site and enters another site through a gap, defect or weakness in the body. It is commonly referred to as “small intestine hernia” and includes umbilical hernia, inguinal hernia, hiatal hernia, incisional hernia, recurrent surgical hernia, white line hernia, femoral hernia, etc. Most of the hernias are caused by coughing, sneezing, overexertion, abdominal hypertrophy, forceful defecation, pregnancy, excessive crying of children, and degenerative changes in the strength of the abdominal wall in old age. The formation of hernia has a great relationship with the patient’s constitution. It is mostly caused by negative pressure in the abdominal cavity due to coughing, sneezing, excessive force, excessive abdominal fat, forceful defecation, women’s pregnancy, excessive crying of children, degenerative changes in the strength of the abdominal wall in old age, etc., which leads to an increase in the air pressure in the abdominal cavity and forces the free organs in the abdominal cavity such as: small intestine, appendix, greater omentum, bladder, ovaries, fallopian tubes and other organs to see the holes in their original part, through a normal or abnormal weak point or defect or orifice of the body into another part. The symptoms of a hernia are most often in the inguinal region, where the lump can be seen or felt. In infants, it is most often detected by the mother during diaper changes, while in older children it is most often detected during bathing or during health visits. The most common cause of a mass is crying, and others include coughing, defecation, and urination. Older children may be made to stand and abdominal pressure may also trigger the appearance of a mass, which may be seen only in the inguinal region or, in some cases, may reach the scrotum or labia. When the child is quiet or sleeping, the mass may appear and disappear. The mass is formed by the prolapse of an organ from the abdominal cavity into the hernia pouch. The prolapsed organ is mostly the small intestine, so it feels soft to the touch and is often accompanied by a gurgling noise when retreating. In women, the ovaries are more often prolapsed, so a thumb-sized, hard and mostly painful lump can be felt. In addition to seeing or feeling the lump, some children may experience constipation, loss of appetite, and vomiting, while others may become easily crying and restless. If the scrotal hernia is too large, it may cause mobility problems. Hernia first affects the digestive system, resulting in symptoms such as lower abdominal cramping, bloating, abdominal pain, constipation, poor nutrient absorption, fatigue and decreased physical fitness. Since the inguinal region is adjacent to the genitourinary system, older patients are prone to bladder or prostate diseases such as frequent urination, urgent urination, and increased nocturia; children may be affected by the extrusion of the hernia and the normal development of the testicles; and middle-aged and young patients are prone to sexual dysfunction. The intestinal canal or omentum inside the hernia sac is prone to inflammatory swelling caused by extrusion or collision, resulting in difficulty in hernia retraction, which can lead to hernia impaction and dangerous conditions such as intestinal obstruction, intestinal necrosis, and severe abdominal pain. Surgical treatments include hernia repair, hernia patch repair, and laparoscopic hernia repair Tension-free hernia repair: Principle of surgery: A one-piece artificial mesh larger than the hernia notch is used to repair and strengthen the damaged abdominal wall notch. The upper and lower artificial mesh layers can be applied to the inner and outer side of the damaged abdominal wall, which can strengthen the pressure resistance by applying the pressure resistance principle of dam repair, so that the pressure on the abdominal wall can be blocked without increasing the tension on the abdominal wall and reducing the possibility of postoperative pain and recurrence. After three years of follow-up, the recurrence rate of patients using the tension-free 3-in-1 artificial mesh is less than 0.05%, and it has the advantages of short operation time, low pain, and fast recovery, etc. Usually patients only need to be hospitalized for 1-2 days after the operation, and can quickly return to normal work and life. This procedure is reimbursed by medical insurance. Lightweight Partially Absorbable Mesh is a new type of mesh developed with modern technology, which originated in Europe and can be used in the treatment of inguinal hernia. The main features are partially absorbable material and large holes, which allow for less foreign body residue and easy formation of a more elastic crust tissue that fits the abdominal wall structure. With conventional hernia mesh, patients often complain of chronic pain due to limited abdominal wall mobility or a foreign body sensation of the mesh.
