A hernia is medically defined as the displacement of normal tissue or organs from their original site to another site through an underlying cavity. In fact, what the people call a hernia is mainly an inguinal hernia. Hernia is more common in children and older adults. Hernia in children is likely to heal spontaneously within one year of age, but hernia after one year of age is unlikely to heal spontaneously and should be treated surgically. All adult hernias require prompt surgery. What is the best way to perform hernia surgery? With the development of laparoscopic technology, the application of laparoscopic technology for the diagnosis and treatment of hernia in the last two years has shown the advantages of less trauma, clear diagnosis, complete repair and fast recovery, making it the best choice for modern hernia treatment. Laparoscopic observation of inguinal hernia laparoscopy allows an easy and comprehensive view of the bilateral groin from inside the abdominal cavity, enabling timely detection of the contralateral occult hernia (about 20%) that is usually missed because of the absence of seizures, so that the bilateral hernia can be solved simultaneously in one operation, avoiding the painful reopening for the contralateral hernia 1 to 2 years after the first operation by traditional surgical methods. For children with hernia, only one to two finger-sized holes need to be made in the stomach, and they can go to the floor and be discharged from the hospital one day after surgery. For adult hernia, only 3 small holes are needed in the abdominal wall, and the patient can usually be discharged 2 days after surgery and resume daily activities in an average of 5 days. In addition, laparoscopic technology can repair hiatus hernia, hiatal hernia and femoral hernia at one time, so laparoscopic repair is more complete compared with other open methods, achieving “one operation for life”. For patients with recurrent hernias after traditional hernia repair, laparoscopy is a boon because it avoids the previous surgical area and solves the problem of difficult reoperation for recurrent hernias. For incisional hernia, white line hernia and lumbar hernia, laparoscopy also shows the advantages of minimally invasive and thorough surgery.
