An inguinal hernia is an extra-abdominal hernia that occurs in the inguinal region, where a hernial sac structure exists that protrudes toward the body surface and where organs or tissues in the abdominal cavity can enter the sac through a congenital or acquired abdominal wall defect. A typical inguinal hernia has a hernia ring, hernia sac, hernia contents and hernia cover. Based on the anatomical concept of “pubic foramen”, inguinal hernias include hiatal hernias, straight hernias, femoral hernias and, more rarely, anterior and lateral femoral vascular hernias. Adult hernias are not self-healing and surgery remains the only curative method available. Symptomatic inguinal hernias should be operated on electively; incarcerated and strangulated hernias should be operated on urgently. In recent years, laparoscopic inguinal hernia repair has gradually become the gold standard for the treatment of inguinal hernia, and more and more doctors and patients are opting for this surgical option. The laparoscopic technique has the following advantages over the traditional open surgery: 1. The patient can be discharged in 2-3 days after laparoscopic surgery and can basically resume normal life, work or study after discharge, which is especially important for young people who need to resume normal work or life as soon as possible; 3, the postoperative reaction is mild: after traditional open surgery, the patient often increases the burden on the heart, lungs and other organs due to pain and other stimuli; while after laparoscopic surgery, the patient often basically does not increase the burden on the heart and lungs and other organs. This is especially beneficial for elderly patients with poor function of heart and lung organs; 4, cosmetic effect: traditional open surgery requires a 6-8 cm long incision in the groin area, while laparoscopic surgery only requires three small 0.5-1.0 cm incisions in the abdominal wall, with significant cosmetic effect; 5, light foreign body sensation at the surgical site after surgery, traditional open surgery will Although most of them will be gradually relieved within six months, there are some who have been difficult to relieve; 6. laparoscopic surgery can explore and find hidden hernia, and treatment of bilateral inguinal hernia does not require additional incisions, which can achieve twice the effect with half the effort; 7. laparoscopic surgery for recurrent hernia can avoid the original surgical incisions, which makes the surgery simpler.
