Inguinal hernia is a disease in which the intestinal canal and greater omentum in the abdominal cavity prolapse outside the abdominal wall or into the scrotum through a defect in the abdominal wall, the inguinal canal or rectal hernia triangle, and its formation has both congenital and acquired factors. Congenital factors: In men, during embryonic development, both testes enter the scrotum at different times, the left side first and the right side second, which determines that the spermatic sheath on the left side closes into cords before the right side, while the spermatic sheath on the right side closes delayed or not, resulting in the communication between the abdominal contents and the testicular sheath on the right side, which forms the congenital basis of inguinal hernia. Acquired factors: All factors that cause increased intra-abdominal pressure become acquired factors of inguinal hernia, such as long-term chronic cough, prostatic hypertrophy, constipation, weight bearing, long-term standing, increased intra-abdominal pressure can force the intestinal canal and large omentum to dislodge from the abdominal cavity, coupled with the patient’s frailty, aging and malnutrition, which makes the abdominal wall lose tension and muscle atrophy and cannot resist intra-abdominal pressure, thus forming inguinal hernia. If the inguinal hernia is formed gradually, in the early stage, the intestinal canal and large omentum freely enter and leave between the abdominal cavity and scrotum, and when standing, they come out, and when lying down, they can return to the abdominal cavity, with obvious feeling of swelling and inconvenience in life and work, and with the passage of time, the hernia sac becomes bigger and bigger, and in some cases, it even becomes a small abdominal cavity, and the long-term rubbing of the intestinal canal and large omentum makes the neck of the hernia sac narrow, and in the later stage, the intestinal canal and large omentum adhere to the neck of the hernia sac and Later, the intestinal canal and omentum adhere to the hernial neck and cannot be returned to the abdominal cavity, resulting in impaired blood circulation, intestinal obstruction, intestinal necrosis and intestinal perforation, which can be life-threatening in serious cases. Some inguinal hernias have sudden onset and no mass in the inguinal region or scrotum in the past, but after sudden exertion, a cystic mass appears in the inguinal region or scrotum and cannot be returned to the abdominal cavity, accompanied by severe pain, abdominal distension, nausea, vomiting, and no bowel movement, which is a kind of ingrown inguinal hernia causing intestinal obstruction. The main difference is the method of repairing the abdominal wall defect. There is the repair of the anterior wall of the inguinal canal, in which the inferior arch of the internal oblique and transverse abdominal muscles is sutured to the inguinal ligament in front of the spermatic cord, which is mainly suitable for adolescent patients; the repair of the posterior wall of the inguinal canal, in which the inferior arch of the internal oblique and transverse abdominal muscles is sutured to the inguinal ligament in front of the spermatic cord This is mainly indicated in middle-aged and elderly patients; there are also repairs of the external oblique tendon after the above-mentioned repairs or of the transversus abdominis fascia, and in the case of giant inguinal hernias, the broad fascia is also reversed. The disadvantage is that because of the large distance between the lower edge of the arch of the internal oblique and transversus abdominis muscles and the inguinal ligament, forcing them to be repaired with high tension, the patient often feels tugging after surgery and is afraid to walk upright for a long time. Due to the local developmental and nutritional abnormalities and the high tension after repair, if the patient still has the factor of increased intra-abdominal pressure, there is a certain rate of hernia recurrence after surgery, which is now less used. In modern times, a tension-free repair is used to treat inguinal hernia, in which the neck of the hernia sac is ligated at a high level and then repaired with a strong artificial patch between the hernia sac and the spermatic cord, with sutures above and below the inferior arch and inguinal ligament, respectively, which achieves the purpose of repair without increasing the local tension, and the patient feels comfortable without pulling after repair, and the recurrence rate is low. This method is based on the principle that when the intestinal canal and the greater omentum touch the hernia sac in the abdominal cavity, the force is dispersed by the mesh plug protruding into the abdominal cavity, which makes it less likely to recur. Due to the high histocompatibility of the hernia patch, it is usually not eliminated by rejection reactions.
