Surgery
Surgery has generally been recommended for all
inguinal hernias to avoid complications such as
strangulation, in which a loop of intestine becomes tightly trapped in a
hernia, cutting off the blood supply to that part of the intestine. But surgery
may not be needed if the hernia is small and you do not have symptoms. Consult
with your doctor to
decide if you need hernia repair surgery.
If a hernia in an adult can be pushed back (reduced), surgery can
be done at the person's convenience. If it cannot be pushed back, surgery must
be done sooner.
- During surgery, the hernia sac is removed and
occasionally a couple of stitches are used to close the opening of the
inguinal canal nearest the abdominal cavity (internal
ring).
- Most hernia repairs are done as outpatient surgery.
Anesthesia can be local, spinal, or general.
- The use of synthetic
patches or mesh for hernia repair is becoming standard for adult surgery. The
mesh or patch is used to strengthen the abdominal wall and prevent hernias from
recurring. Previously, these were used mostly for hernias that were large or
hard to repair.
Laparoscopic hernia surgery may have some advantages over open
surgery in
certain situations. Studies show that people have less
pain after this type of surgery and return to work and other activities more
quickly than after open repair. But laparoscopic surgery is more expensive than
open repair. And laparoscopic surgery has a higher risk for serious
complications.3 Recurrence rates are also higher with
laparoscopic repair.4
The risk of a hernia coming back after surgery varies depending on
a surgeon's experience, the type of hernia, the method of surgery, and the
person's age and overall health.
- Recurrence rates after hernia repair are lower
when experienced surgeons perform the procedure, especially for laparoscopic
techniques.5
- The chance of a hernia coming
back after open surgery ranges from 1 to 10 out of every 100 open surgeries
done.6
- Up to 10% of hernias repaired with laparoscopic surgery may
recur.4 Some studies have found recurrence rates as
low as 0.25% to 2% for laparoscopic surgery.7
- Using mesh to repair the weak muscle in the
stomach wall makes it up to half as likely that the hernia will come
back.8
Should I have surgery for inguinal hernia now,
or should I wait?
Surgery in children
In most cases, a child with an inguinal hernia will need
surgery to correct it.
Infants 6 months of age and younger who have inguinal hernias
have a much higher risk of strangulation than older children and adults.
Therefore, surgery for inguinal hernias in infants is not delayed like it can
be for adults.
- Synthetic patches are not needed to repair an inguinal hernia
in an infant.
- Some infants with an inguinal hernia may need to be
hospitalized for surgery rather than have it in an outpatient setting. These
include infants with lung problems, seizure disorders, or heart diseases from
birth or those who were born prematurely.
Children are less likely than adults to have a hernia come back.
Recurrence in children is less than 1%.1
One of the major decisions concerning infants and children is
whether to explore the opposite
groin area for a hernia during a hernia repair. A
hernia develops in the other side of the groin in about 30% of children who
have had hernia surgery. The risk of developing a hernia on the other side is
up to 50% in infants who had hernia surgery during the first year of
life.1
Issues to consider in deciding whether the other side should be
explored include the overall health of the child, the risk of
incarceration of a hernia, and the experience level of
the surgeon (how many of these surgeries the doctor has performed and his or
her recurrence rates).
Surgery Choices
Two types of surgery are done to repair inguinal hernias:
- Open hernia repair
(herniorrhaphy, hernioplasty)
- Laparoscopic hernia
repair
What To Think About
Studies show that the numbers of hernias that come back (recur)
after laparoscopic surgery are higher than with open hernia repair using
mesh.4 The laparoscopic procedure causes less pain and
numbness after surgery and generally allows you to return to work and
activities sooner. But serious complications such as bladder injury are more
likely to occur with a laparoscopic procedure. Also, the success of a
laparoscopic surgery depends more on the surgeon's experience, and laparoscopic
surgery is more expensive than open surgery.3
Laparoscopic surgery may not be possible for a person who has
tissues that have grown together (adhesions) from previous abdominal
operations.
Most hernias that will recur do so within 5 years after
surgery.
There are some
considerations before having inguinal hernia repair
surgery. Talk with your doctor so that you make the best decision for
your condition.
Recurrent inguinal hernias are more difficult to repair and pose
more risks than initial hernia repairs. The risks associated with recurrent
hernia surgery are more scar tissue, numbness and pain after surgery, and a
greater chance of injury to a testicle or the
spermatic cord.
Conditions that might increase the risk of recurrence
include abdominal muscles that are not strong or healthy enough to "hold" the
stitching (suture) material and bleeding or infection that weaken the
repair.
Fertility is usually not affected by an inguinal hernia or hernia
surgery. But in males there is a chance that surgery or an incarcerated hernia
can cause injury to the
vas deferens, the tube that carries sperm from the
testicles to the urethra.1 It is not yet known how
often or to what degree this affects a man's ability to father a child.
