Since Bassini’s hernia repair surgery in the 1880s ushered in a new era of modern hernia surgery, abdominal wall hernia repair has become one of the most common procedures in general surgery and is performed on approximately one million inguinal and abdominal wall hernia patients worldwide each year. Common traditional surgical approaches include Ferguson, Bassini, Halsted, and Shouldice. Despite its more than 120 years of history, the Bassini method is still the most clinically used inguinal hernia repair, mainly in younger patients and those with smaller hernia sacs. If the Bassini repair was a landmark in the history of hernia surgery, the tension-free hernia repair is another revolution in the history of hernia surgery. It has reduced the recurrence rate after hernia surgery from 15-20% to about 2%. The efficacy of the procedure is very clear. The current patches for tension-free hernia repair are mainly divided into: single patch, single patch with mesh plug, Kugel and double patch (PHS, mKugel, Millikan). The materials of the patches are polypropylene and expanded PTFE. Kugel patches are characterized by an elastic memory ring around the periphery, which allows the patch to be placed without curling, which facilitates the operation and reduces the chance of postoperative recurrence. In inguinal hernia repair, the Kugel is more anatomically correct than the Plug, and is characterized by less trauma, better repair (it can cover the hernia, straight hernia, and femoral hernia areas simultaneously), less foreign body sensation, and less chance of nerve injury. However, surgeons often feel uncomfortable when they first encounter the Kugel procedure. The main reason is that the Kugel procedure requires freeing the anterior peritoneal space, which is different from previous procedures. It is used with good results in giant hernias, compound hernias (saddle hernia) and multiple recurrent hernias (unused patches). In the area of inguinal hernia repair, we note a “pubic tuberosity hernia”, where the hernia ring is close to the pubic tuberosity. This hernia can be primary or recurrent, including recurrent hernias after the application of a patch. To avoid recurrence of hernias after patch application, we emphasize that the suture between the patch and the pubic symphysis must be secure. This type of hernia often has a tough hernia ring, and the application of a mesh plug repair is simple and easy with good results. In the management of complex inguinal hernias, Kugel is an excellent choice. We have managed many recurrent giant sliding hernias, bilateral giant hernias and compound hernias with excellent results. In conclusion, Kugel is an excellent approach for patients with particularly severe defects in the posterior wall of the inguinal canal. In ventral wall hernia repair, we emphasize tension-free. It is preferable to apply a patch of expanded polytetrafluoroethylene material for intra-abdominal repair, and the patch should be large enough to exceed the hernia ring by about 5 cm on each side, with additional attention to the placement of subcutaneous drainage. For the repair of umbilical hernia, we appreciate that the umbilicus can be completely preserved. If the hernia ring is less than 2 cm, no patch can be used, but the rest of the patch should be used. The above are our experiences and are only for communication.
