Signs and Symptoms
They typically present when standing erect as a groin lump or bulge, which may differ in size during the day, based on internal pressure variations of the intestine. The bulge or lump typically is smaller or may not be visible in a prone position.
They may or may not be associated with pain. Often, they present with a varying degree of complication ranging from irreducibility through intestinal obstruction to frank gangrene of contained bowel. The incidence of strangulation in femoral hernias is high. A femoral hernia has often been found to be the cause of unexplained small bowel obstruction.
The obvious finding may be a lump in the groin. Cough impulse is often absent and should not be relied on solely when making a diagnosis of femoral hernia. The lump is more globular than the pear shaped lump of the inguinal hernia. The bulk of a femoral hernia lies below an imaginary line drawn between the anterior superior iliac spine and the pubic tubercle (which essentially represents the inguinal ligament) whereas an inguinal hernia starts above this line. Nonetheless, it is often impossible to distinguish the two preoperatively.
