With minimally invasive surgery, one or more small incisions are made that allow the surgeon to use a surgical camera and small tools to repair the hernia.Either open or minimally invasive surgery may be performed under general or regional anesthesia, depending on the extent of the intervention needed. Three approaches have been described for open surgery:

Lockwood’s infra-inguinal approach
Lotheissen‘s trans-inguinal approach
McEvedy’s high approachThe infra-inguinal approach is the preferred method for elective repair. The trans-inguinal approach involves dissecting through the inguinal canal and carries the risk of weakening the inguinal canal. McEvedy’s approach is preferred in the emergency setting when strangulation is suspected. This allows better access to and visualization of the bowel for possible resection. In any approach, care should be taken to avoid injury to the urinary bladder which is often a part of the medial part of the hernial sac. Repair is either performed by suturing the inguinal ligament to the pectineal ligament using strong non-absorbable sutures or by placing a mesh plug in the femoral ring. With either technique care should be taken to avoid any pressure on the femoral vein. Postoperative outcome
Patients undergoing elective surgical repair do very well and may be able to go home the same day. However, emergency repair carries a greater morbidity and mortality rate and this is directly proportional to the degree of bowel compromise. Epidemiology
Femoral hernias are more common in multiparous females, which results from elevated intra-abdominal pressure that dilates the femoral vein and in turn stretches femoral ring.
An intraneural perineurioma is a rare benign tumor within the sheath of a single nerve that grows but typically does not recur or metastasize. These lesions are only composed of perineurial cells, cloned from a single cell. They are distinct from schwannoma and neurofibroma. Intraneural perineurioma is a neoplastic proliferation of perineurial cells with unique immunohistochemistry and ultrastructural features, and it is distinct from other onion bulb Schwann cell-derived entities. Despite harboring molecular abnormalities of the long arm of chromosome 22, intraneural perineurioma has not been associated with neurofibromatosis.Due to the involvement of one or more nerve fascicles, intraneural perineuriomas are distinguished by a localized, solitary expansion of peripheral nerves. These tumors develop slowly or stay stable over time. References
