as an example, the UK's National Health Service spends £56 million a year in repairing inguinal hernias, 96% of which were repaired via the open mesh approach while only 4% were done laparoscopically. Open hernia repair All techniques involve an approximate 10-cm incision in the groin. Once exposed, the hernia sac is returned to the abdominal cavity or excised and the abdominal wall is very often reinforced with mesh. There are many techniques that do not utilize mesh and have their own situations where they are preferable. Open repairs are classified via whether prosthetic mesh is utilized or whether the patient's own tissue is used to repair the weakness. Prosthetic repairs enable surgeons to repair a hernia without causing undue tension in the surrounding tissues while reinforcing the abdominal wall. Repairs with undue tension have been shown to increase the likelihood that the hernia will recur. Repairs not using prosthetic mesh are preferable options in patients with an above-average risk of infection such as cases where the bowel has become strangulated (blood supply lost due to constriction). One large benefit of this approach lies in its ability to tailor anesthesia to a person's needs. People can be administered local anesthesia, a spinal block, as well as general anesthesia. Local anesthesia has been shown to cause less pain after surgery, shorten operating times, shorten recovery times as well as decrease the need to return to the hospital. However, people who undergo general anesthesia tend to be able to go home faster and experience fewer complications. The European Hernia Society recommends the use of local anesthesia particularly for people with ongoing medical conditions. Open mesh repairs Repairs that utilize mesh are usually the first recommendation for the vast majority of patients including those that undergo laparoscopic repair. Procedures that employ mesh are the most commonly performed as they have been able to demonstrate better results compared to non-mesh repairs. Approaches utilizing mesh have been able to demonstrate faster return to usual activity, lower rates of persistent pain, shorter hospital stays, and a lower likelihood that the hernia will recur. Options for mesh include either synthetic or biologic. Synthetic mesh provides the option of using "heavyweight" as well as "lightweight" variations according to the diameter and number of mesh fibers. Lightweight mesh has been shown to have fewer complications related to the mesh itself than its heavyweight counterparts. It was additionally correlated with
