Evidence suggests that watchful waiting of inguinal hernias (IH) is safe because the risk of acute strangulation requiring an emergent repair is low. However, population-based incidence rates are lacking, and it is unknown whether the incidence of emergent inguinal hernia repairs (IHR) has changed over time. ⋯ The incidence of emergent IHR is low. This risk has decreased over the past 20 years. However, patients who are either ≥70 years old, obese, with a high ASA score, or with a femoral or recurrent hernias are more likely to require an emergent IHR and could benefit from elective operative intervention if deemed adequate surgical candidates.

About 30% of all female 'groin' hernias are femoral hernias, although often only diagnosed during surgery. A Lichtenstein repair though, as preferred treatment modality according to guidelines, would not diagnose and treat femoral hernias. Totally extraperitoneal (TEP) hernia repair, however, offers the advantage of being an appropriate modality for the diagnosis and subsequent treatment of both inguinal and femoral hernias. TEP therefore seems an appealing surgical technique for women with groin hernias. ⋯ Femoral hernias are common in women with groin hernias, but not always detected preoperatively; this argues for the use of a preperitoneal approach. TEP hernia repair combines the advantage of a peroperative diagnosis and subsequent appropriate treatment with the known good clinical outcomes.

Small femoral hernias may be difficult to diagnose by physical examination and are sometimes identified unexpectedly by laparoscopy. The aim of this study was to examine the incidence of unsuspected femoral hernia discovered during laparoscopic inguinal hernia repair in two well-defined patient groups. ⋯ Unsuspected femoral hernias are more prevalent in patients with recurrent hernia than in patients with primary hernia in the inguinal region. Femoral hernias may be unrecognized at the primary inguinal hernia operation, or the previous inguinal hernia operation may facilitate the formation of a femoral hernia. Unsuspected femoral hernias are especially frequent in women with recurrent inguinal hernia. In women with a groin hernia, a femoral hernia should always be excluded by laparoscopy or by open exploration of the preperitoneal space.
