Abdominal wall hernias are caused by protrusion of abdominal organs along with the peritoneum through a weak spot or orifice in the abdominal wall. It can occur at all ages. Inguinal hernias are the most common. Others are femoral hernia, umbilical hernia, white line hernia, incisional hernia, etc. In normal people, there are areas of weakness in the abdominal wall, such as the inguinal canal and femoral ring. In addition, some people have defects in the development of a part of the abdominal wall, such as incomplete atresia of the umbilical ring and defective white line of the abdomen. There are also surgical incisions, injuries to the abdominal wall caused by trauma, and weakness of the abdominal wall muscles due to muscle atrophy in old age are prerequisites for the occurrence of abdominal wall hernias. Increased intra-abdominal pressure, such as chronic cough, constipation, difficulty in urination, frequent crying of infants, weight lifting, vomiting, etc., increases the intra-abdominal pressure and extrudes a small pocket of abdominal organs through the weakness of the abdominal wall, called a hernia sac. Most of the organs can be returned to the abdominal cavity and are called reversible hernias, while some require gentle rubbing to return. In some cases, the gap in the abdominal wall is small and the extruded abdominal organs cannot be returned by force, called an incarcerated hernia; in others, the compression of blood vessels and the ischemia of only the protruding organs is called strangulated hernia. Strangulated hernia can cause annular death of the protruding organ. If the protrusion is intestinal, it can cause intestinal obstruction, intestinal necrosis, perforation, and peritonitis. A fecal fistula can also be formed by penetration of the abdominal wall. After the hernia is formed, the hernia sac gradually enlarges with repeated protrusion of organs. Adult hernias are not self-healing and surgery is the only effective treatment. Open surgery is performed through a 6-8 cm incision in the inguinal region, while laparoscopic surgery involves making three small 0.5-1.5 cm holes in the lower abdominal wall to return the hernia sac into the abdominal cavity and covering the herniated gap with artificial mesh. This approach can simultaneously cover the weak and defective areas where hiatal, ventral and femoral hernias tend to occur, reducing the hernia recurrence rate to 0.1%. Minimally invasive laparoscopic hernia repair has a small wound, mild postoperative pain, quick recovery, and little chance of wound infection, so that the patient can go home the day after surgery and return to work 1-2 weeks after surgery. The laparoscopic minimally invasive hernia repair is preferred for elderly patients whose medical condition allows it, especially for bilateral hernia and recurrent hernia patients. In addition, for other abdominal wall hernias, such as umbilical hernia, incisional hernia, surgical recurrent hernia, white line hernia, etc., traditional surgery often requires open surgery, which is very traumatic and slow in patient recovery. Currently, laparoscopic hernia repair is also an option for these abdominal wall hernias. Minimally invasive abdominal wall hernia repair is performed by making three holes in the abdominal wall, entering the abdominal cavity, returning the intestinal canal inside the hernia sac into the abdominal cavity, and then making a “patch” in the weak abdominal wall hernia area. Normal activities can be performed the day after surgery. Minimally invasive hernia repair is a new hope for the healing of patients with abdominal wall hernia.
