Definition

A femoral hernia repair, or herniorrhaphy, is a surgical procedure performed to reposition tissue that has come out through a weak point in the abdominal wall near the groin. In general, a hernia is a protrusion of a loop or piece of tissue through a weak spot or opening in the abdominal wall. There are several different kinds of hernias; they are named according to their location. A femoral hernia is one that occurs in a person’s groin near the thigh. In a child, a femoral hernia is usually the result of incomplete closing of this area during development in the womb.

Purpose

Femoral hernia repair is done to reduce the patient’s risk of a future surgical emergency. A hernia may be congenital (present at birth) or may develop later in life because of a weakness in the abdominal wall. If the opening is very small, the amount of tissue that can push through it is small, and the person may barely be aware of the problem. One complication that may arise, however, is that the tissue that comes out through the opening can become incarcerated, or trapped. If the herniated tissue has its blood supply diminished because of pressure from other nearby organs or structures, it is referred to as strangulated. Strangulation may lead to gangrene, which means that the affected tissue can die and be invaded by bacteria. Femoral hernias are more likely than other hernias to become incarcerated or strangulated because the affected tissue pushes through a relatively small and closely confined space. Because of the increased risk of eventual strangulation and gangrene, the patient’s doctor may recommend surgical repair of the hernia.

Demographics

Femoral hernias are a relatively uncommon type, accounting for only 3% of all hernias. While femoral hernias can occur in both males and females, almost all of them develop in women because of the wider bone structure of the female pelvis. Femoral hernias usually grow larger over time; any activity that involves straining, such as heavy lifting or a chronic cough, may cause the hernia to enlarge. Poor abdominal muscle tone, obesity, and pregnancy also increase a woman’s risk of developing a femoral hernia. Most femoral hernias develop on only one side of the patient’s abdomen, but about 15% of femoral hernias are bilateral. These bilateral hernias are more likely to become strangulated. An additional 20% of femoral hernias become incarcerated.

Femoral hernias are more common in adults than in children. Those that do occur in children are more likely to be associated with a connective tissue disorder or with conditions that increase intra-abdominal pressure. Seventy percent of pediatric cases of femoral hernias occur in infants under the age of one.

Description

Femoral hernia repair may be performed under either general or local anesthesia. The repair of the hernia involves a cut, or incision, in the groin area (near the thigh, adjacent to the femoral artery). The surgeon locates the hernia, and reduces it by pushing the protruding tissue back inside the abdominal cavity. A hernia is referred to as reducible when the tissue that has come out through the opening can be pushed back and the opening closed. If incarceration or strangulation has occurred, the hernia is referred to as irreducible.

The procedure may be performed using the traditional open method, which requires a larger surgical incision, or by a laparoscopic approach. A laparoscopic procedure is performed through a few very small incisions. The hole in the abdominal wall may be closed with sutures, or by the use of a fine sterile surgical mesh . The mesh, which provides additional strength, is sewn into the abdominal wall with very small stitches . Some surgeons may choose to use the

mesh when repairing a larger hernia. A hernia repair done with a mesh insert is called a tension-free procedure because the surgeon does not have to put tension on the layer of muscle tissue in order to bring the edges of the hole together. A laparoscopic hernia repair takes about 40 minutes to complete.

KEY TERMS

Bilateral— Occurring on both the right and left sides of the body.

Femoral— Pertaining to the thigh region.

Gangrene— The death of a considerable mass of tissue, usually associated with loss of blood supply and followed by bacterial infection.

Hernia— The protrusion of a loop or piece of tissue through an incision or abnormal opening in other tissues. A femoral hernia is one that develops near the upper thigh in the groin area.

Herniorrhaphy— The medical term for a hernia repair.

Incarceration— The abnormal confinement of a section of the intestine or other body tissues. A femoral hernia may lead to incarceration of part of the intestine.

Intra-abdominal pressure— Pressure that occurs within the abdominal cavity. Pressure in this area builds up with coughing, crying, and the pressure exerted when bearing down with a bowel movement.

Reduction— The correction of a hernia, fracture, or dislocation.

Strangulation— A condition in which a vessel, section of the intestine, or other body part is compressed or constricted to the point that blood cannot circulate.

Diagnosis/Preparation

Diagnosis

A femoral hernia is usually diagnosed during a physical examination. In many cases, the patient will consult the doctor because of pain in the groin area or the inside of the upper thigh. The pain or discomfort of a femoral hernia may come and go, increasing when the person coughs or strains. If the pain is severe, the patient may go to an emergency room. In young children, symptoms of an incarcerated femoral hernia include severe irritability, abdominal pain, cramping, and vomiting. Adult patients may have also felt a mass in the groin that may be tender when it is pressed. Patients in severe pain may be given a sedative or pain-killing medication so that the doctor can examine the groin area and try to guide the herniated tissues back through the abdominal opening with gentle manual pressure.

In adult patients, the doctor will rule out the possibility that the pain is caused by an enlarged lymph node, a lipoma, or an inguinal hernia. Imaging studies are not generally used in diagnosing a hernia unless the doctor suspects that the hernia is incarcerated or strangulated. A strangulated hernia can be distinguished from an incarcerated hernia by the presence of fever, pain that persists after the doctor has reduced the hernia manually, and pain that is more severe than warranted by the examination findings.

Preparation

If the doctor suspects that the hernia is strangulated, he or she will give the patient a broad-spectrum antibiotic (usually cefoxitin) intravenously before the patient is taken to the operating room .

Adults scheduled for a nonemergency herniorraphy are given standard blood tests and a urinalysis . They should not eat breakfast on the morning of the procedure, and they should wear loose-fitting, comfortable clothing that they can easily pull on after the surgery without straining their abdomen.

Aftercare

Aftercare depends on several factors: the patient’s age and general health status; the type of surgery (open or laparoscopic); and the type of anesthesia administered. Immediately after the procedure, the patient will be taken to the recovery area of the surgical center and monitored for signs of excessive bleeding, infection, uncontrolled pain, or shock. An uncomplicated femoral hernia repair is usually performed on an outpatient basis, which allows the patient to go home within a few hours of the surgery.

The patient will be given instructions about incision care, which will depend on the type of surgery and the way in which the incision was closed. Sometimes a transparent dressing is placed on the wound that the patient can remove about three days after the procedure. Very small incisions, such as those used for laparoscopic surgery, may be closed with Steri-strips ® instead of sutures. The incision should be kept dry, so patients should take a sponge bath rather than a shower or tub bath for several days after surgery.

Adults should avoid heavy lifting for several weeks after a hernia repair. The surgeon can give the patient advice about specific weight limits on lifting. Contact sports and vigorous exercise should be avoided for about three weeks after a femoral hernia repair. Many patients will be able to return to most of their daily activities in a few days, with complete

WHO PERFORMS THE PROCEDURE AND WHERE IS IT PERFORMED?

This procedure is performed by a general surgeon. As with any procedure, the more experience the surgeon has with the particular surgery being performed, the better the expected outcome. A femoral hernia repair is usually performed on an outpatient, or ambulatory, basis in a hospital. After a few hours of recovery in the surgical center, the patient is able to return home.

recovery taking about a month in patients without other medical conditions.

Risks

All surgical procedures have associated risks, both surgical and anesthesia-related. Bleeding and infection are the two primary surgical risks. The risk of infection for an uncomplicated femoral hernia repair is about 1%. Anesthesia-related risks include reactions to the anesthetic agents, including interactions with over-the-counter and herbal preparations, as well as potential respiratory problems. There is a small risk of recurrence of a femoral hernia. In addition, female patients are at some risk of injury to the nerves and blood supply of their reproductive organs, because femoral hernias develop in a part of the abdominal wall that is close to the uterus and ovaries.

Normal results

Normal results with timely diagnosis and repair of a femoral hernia are a smooth recovery with no recurrence of the hernia.

Morbidity and mortality rates

The mortality rate following an uncomplicated femoral hernia repair is essentially zero. The mortality rate for repair of a strangulated hernia that has necessitated a bowel resection is higher, however, ranging from 5–19%. Morbidity following an uncomplicated herniorraphy is low; one Danish study reported that the most common complication, reported by 8% of patients, was pain during procedures performed under local anesthesia. A British study of laparoscopic hernia repairs found that only 22 out of 3017 patients reported recurrence of the hernia. The incidence of postoperative swelling and bruising was 8%.

QUESTIONS TO ASK THE DOCTOR

  • How many femoral hernia repairs have you performed?
  • Am I a candidate for laparoscopic surgery?
  • How many femoral hernia repairs have you performed with a laparoscope?
  • What kinds of complications have your patients experienced?
  • How long is my recovery likely to take?
  • What limitations will there be on my daily activities, such as returning to work, driving, or lifting a toddler?

Alternatives

There are no medical or surgical alternatives to a femoral hernia repair other than watchful waiting. There is some risk that the hernia will enlarge, however, which increases the risk of incarceration or strangulation. Moreover, the complications and risks of surgery increase with incarcerated or strangulated hernias. Once a hernia is suspected or diagnosed, it should be evaluated by a surgeon within a month to lower the risk of complications.
