The inguinal hernia is a common disease, and if the Bassini procedure is considered as the beginning of modern hernia surgical treatment, its surgical treatment has a history of more than 120 years, during which time there has been a gradual improvement in the understanding of the principles of inguinal hernia surgical treatment, including the level of repair, the repair method, and the repair material, and many different procedures have been designed, taking the current widely used concept of tension-free repair The concept of tension-free repair is now widely used, including Lichtenstein, kugel, PHS, mKugel, Millikan and many other procedures. Anterior surgery is still the main modality for the treatment of inguinal hernias and will remain so in the future because the procedure can be done under local anesthesia, is less invasive, and is easier for the surgeon to learn and do well. In numerous treatment reports, surgeons have focused more on the innovation of the surgical approach or the therapeutic efficacy of a particular procedure and less on the anatomy in the surgical pathway, and authors in the literature tend to be brief in their description of the pathway operation. In our clinical practice, it is obvious that many patients’ postoperative complications are often related to the rationality of their pathway anatomy, such as herniation omission, postoperative pain, and nerve misinjury. There is also a lack of consensus on a standardized anatomical pathway during anterior surgery, and anatomy textbooks focus on a detailed description of the anatomy of the inguinal region, but it is actually a static anatomical description. The anatomical pathway during surgery is a dynamic anatomy that requires individualized anatomical repertoire and manual expressiveness by the surgeon, which is probably why the same anatomical aspects can vary so much from surgeon to surgeon. In fact, there is a “God’s gap” in the inguinal region, which can be accessed through a pathway to complete the repair of “congenital defects” in the inguinal region, and a good dissection of this gap can lead to a reduction of injuries and postoperative complications, especially for the reduction of hernias The dissection of this gap can be used to reduce injuries and postoperative complications, especially to reduce hernia leakages and chronic postoperative pain. The authors describe the anatomical steps of this pathway with many years of experience in the hope that they can provide some personal experience to fellow surgeons, especially beginners. The incision is located on the anterior projection of the inguinal canal, between the inner and outer rings (outer end at 2 cm above the midpoint of the inguinal ligament, inner end at the pubic symphysis), depending on individual differences, 4-5 cm is generally sufficient to complete the operation, if due to obesity can be extended, subcutaneous tissue can be cut in the middle of the incision 2-3 cm and then expanded to the second side, in some cases can be In some cases, the superficial artery under the abdominal wall can be avoided to be cut by this operation. The main issues of attention: 1. dealing with the superficial inferior abdominal wall artery, if cut, attention should be paid to hemostatic measures in place to avoid postoperative subcutaneous hemorrhage. 2. offsetting the position of the incision, if not on the anterior projection of the inguinal canal, will affect the exposure and operation of the surgical area. 2. revealing the anterior plane of the extra-abdominal oblique tendon membrane and the external ring: this step is relatively simple, but to clearly reveal the extra-abdominal oblique tendon membrane and the external ring has two advantages: one is to facilitate the injection of local anesthetic solution into the deep layer of the extra-abdominal oblique tendon membrane, and the other is to facilitate the accurate positioning and incision of the external ring at the midpoint of the external ring. 3, incision of the external ring, external oblique tendon membrane, separation of the deep plane of the external oblique tendon membrane: incision at the midpoint of the external ring, and cut the external oblique tendon membrane to the lateral side of the projection of the internal ring, at this time, the deep part of the levator muscle and the inferior iliac abdominal nerve and the iliac inguinal nerve are revealed, and the deep surface of the external oblique tendon membrane is separated bluntly, the lower part should reach the inguinal ligament and the refractory part of this ligament and the ligament should be clearly revealed, and the upper and lateral parts should be separated according to the needs of different repair methods. The upper and lateral sides are separated according to the needs of different repair methods, and the operation can be easily accomplished by blunt finger separation. The main issue of attention: the middle point of the external ring must be dissected, otherwise the degree of freeing of the upper and lower lobes of the external abdominal oblique tendon membrane will be reduced, which will affect the later exposure and operation. 4.Dissecting the external ring and freeing the spermatic cord: Since the external ring is densely wrapped around the spermatic cord, it needs to be separated sharply when separating the external ring, and it is generally better to separate it with an electric knife. The upper half of the ring should be divided to the lateral edge of the rectus abdominis muscle, and the lower half of the ring should be divided to the pubic tuberosity and reveal this tuberosity. The spermatic cord can be lifted by cutting sharply above the inguinal ligament to reach the anterior plane of the transversus abdominis fascia, then cutting at the gap between the superior border of the levator muscle and the union tendon to reach the posterior aspect of the spermatic cord to enter the anterior plane of the transversus abdominis fascia, and performing upward and downward penetration operations to lift the spermatic cord; after lifting the spermatic cord, it is sharply separated toward the pubic tubercle and crosses the tubercle by about 1 cm. The anterior plane of the transversus abdominis fascia can be separated up to the medial edge of the internal ring, and then some adhesive connective tissue can be cut in the upper and lower part of the internal ring, and then the state of the transversus abdominis fascia ring in the medial part of the internal ring will be clearly revealed without cutting the levator muscle or separating the levator muscle from the spermatic cord. In the case of a straight hernia, the hernia sac is then fully exposed and can be repaired according to the proposed procedure. For example, the hernia sac is incised to separate the anterior peritoneal space. Problems: 1. Inadequate dissection of the external ring and unclear exposure of the pubic symphysis; 2. Insufficient freeing of the spermatic cord; 3. Excision or separation of the levator muscle and eager opening of the spermatic cord sheath to find the hernia sac, which can easily damage the spermatic cord and nerves.
