The general steps of minimally invasive hernia surgery include placing a laparoscope, freeing the peritoneum, returning the contents, placing a patch, and suturing the peritoneum. 1. First, three holes are made in the abdomen to form a pneumoperitoneum and then the laparoscopic head and operating instruments are placed respectively. Through the laparoscope, the peritoneum is freed. 2. The hernia contents are returned to the abdominal cavity. 3. A patch is placed between the hernia sac and the abdominal wall. 4. Finally, the peritoneum is put back together. The advantages of treating hernia through minimally invasive surgery include less trauma, shorter operation time, less pain, and quicker recovery of the patient after the operation. There are certain indications for minimally invasive hernia surgery, and most patients can be treated for hernia by minimally invasive surgery. However, since minimally invasive surgery needs to be performed under general anesthesia, the risk of anesthesia will be increased if there are severe chronic bronchitis, asthma, diabetes and other diseases, so it is necessary to fully consider the risks and make appropriate choices. A history of previous abdominal trauma will also make the surgery more difficult. In order to prevent recurrence after surgery, patients need to improve constipation, chronic bronchitis, prostate hypertrophy and other disease conditions, avoid heavy physical activities to prevent the increase of intra-abdominal pressure.
