Chapter 34. Abdominal Wall Hernias
Of the following open repairs, the most effective method of repairing a femoral hernia is a
B. Lotheissen-McVay repair
The correct answer is D. Lotheissen-McVay repair. The Lotheissen-McVay repair, which brings the conjoined tendon posteriorly and inferiorly to the Cooper ligament, is the only one of the repairs listed that obliterates the opening through which a femoral hernia travels.

A. Overlooking an indirect hernia sac
B. Tension on the fascial repair
C. A missed femoral hernia
D. Failure to close the fascial defect adequately
E. A defect in collagen synthesis

The first four options are the most common reasons why early failures occur. Although a defect in collagen may play a role in predisposing someone to develop a hernia in the first place, the mechanical factors listed are overwhelmingly the most common reasons for hernia recurrence early after repair.
The type of open repair of a groin hernia that is both the most commonly performed and also associated with the lowest rate of recurrence is the
E. Cooper ligament repair
The correct answer is C. Lichtenstein repair. The Lichtenstein repair was developed specifically as a repair that would be associated with less tension on the repair, since tension is one of the major causes of failure of a repair. It is the only one repair listed that employs mesh in the repair. Although the Shouldice repair is reported to have a very low recurrence rate in the hands of those surgeons who employ it, it is far less ...
