The Lichtenstein repair.

The description of the Lichtenstein tension-free mesh repair 12 years ago opened a new era in groin hernia repair. Without the risk for severe morbidity, it can be readily carried out on patients previously considered unsuitable for hernia repair. Fears of complications related to mesh implantation have proved to be without foundation. As a local anesthetic outpatient procedure without the need for complex and expensive instrumentation, combined with the ability of patients to return to work in a short time, overall costs can be kept to a minimum without in any way compromising the safety or the long-term success of the procedure.
