Surgical
treatment of pectus anomalies should be performed by an experienced thoracic
surgeon. Many people with pectus anomaly express great frustration when
trying to obtain advice from their general practitioners (GP) about what
the chest anomaly is and what is the best treatment. A referral to a thoracic
surgeon must be made by a GP. An experienced thoracic surgeon will conduct
a thorough assessment of the chest anomaly and advise the most appropriate
treatment for each individual case. Pectus
correction surgery is usually performed by specialist thoracic surgeons
who have obligations to operate on patients with life threatening diseases.
Because pectus correction surgery is often viewed as cosmetic surgery,
patients often have a long struggle to have their operation performed.
Surgical correction
of pectus anomalies can now be performed with low morbidity, low cost,
minimal limitation in activity and a high frequency of symptomatic improvement.
Fonkalsrud et al (2000) states that more than 97% patients had a very
good or excellent result.
Currently the surgical
options availalbe in the UK are the Ravitch and Nuss procedures.
Please note, however,
any type of surgery leaves a scar, is very painful and complications include
wound infections and post-operative pain.
In severe cases, correction may not be total and recurrence can take place.
Information on each
of these operations is given below, including the advantages and disadvantages
of each procedure.

Ravitch procedures
(Photo Illustations)
In the Ravitch procedure, the rib cartilages are cut away on each side
and the sternum is flattened so that it will lie flat. One or more bars
(or “struts”) may then be inserted to ensure the sternum keeps
it
shape. This is the procedure we use for complex pectus anomalies
and for pectus carinatum.
The operation involves making a horizontal cut from one side of the
chest to the other. Drains are inserted on each side of the chest to
remove any fluid from the surgical site and the wound is closed
using dissolvable stitches. If a strut is inserted it is intended to
remain in place permanently but may be removed if it causes pain or
other problems.

Nuss Procedure or Minimally Invasive Repair of Pectus Excavatum
(MIRPE) (Photo

Developed by Dr Nuss in the 1980s, the MIRPE or Nuss procedure
involves placing one or two curved steel bars behind the sternum,
forcing it back into a more normal shape. Drains are then inserted
on either side of the chest to remove any fluid from the surgical site.
This procedure can only be used for pectus excavatum.
In children, the bar is removed after two years once permanent
reshaping has occurred. In adults, the bar is currently left in place
for
at least three to five years. Some patients prefer to keep the bar
permanently as it reduces the risk that their pectus anomaly will
come back.

What
are the advantages of the Ravitch procedure and the Nuss
procedure?
Advantages:
the Ravitch procedure
- It is a tried
and tested method for correcting pectus anomaly.
Research shows that 97 per cent of patients stated they have very
good or excellent results with this procedure.
- Once the procedure
has been performed, it is extremely unlikely
that the anomaly will happen again.
Advantages:
the Nuss procedure (minimally invasive repair of pectus
excavatum – MIRPE)
- It is a minimally
invasive operation – only four to five small incisions
are needed (an incision of four to five centimetres on each side of
the
chest; two chest drain incisions of one to one and a half centimetres
each; and a two centimetre incision below the tip of the sternum).
- It does not involve
cutting or removal of cartilage.
- There is generally
minimal blood loss during the procedure. It is
unusual for a patient having this operation to require a blood
transfusion.
- It is generally
a quicker operation than the Ravitch procedure.
- A recent article
on the experience of Nuss procedure patients at
Royal Brompton showed that 85 per cent thought that their decision
to have the operation was the right one.

What
are the disadvantages of the Ravitch procedure and the Nuss
procedure?
Disadvantages:
the Ravitch procedure
- There is a large
incision, although this normally fades to a thin line.
- The procedure is
a more extensive operation than the Nuss
technique.
Disadvantages:
the Nuss procedure
- As it is quite
a new procedure there is not yet reliable data on how
well it works in the longer term.
- Generally the procedure
is straightforward but it can sometimes be
more difficult to carry out in adults than in children.
- There are not yet
clear guidelines on when to remove the bar in
adults. It is possible that the anomaly will reoccur once the bar is
removed.
- Though very rare,
injury to the heart when positioning the bar can
happen. Your surgeon will use various techniques to minimise this
risk and will discuss these with your prior to the procedure.

What
are the benefits of surgical treatment for pectus anomaly?
Surgery will improve
the shape of your chest which may improve
your self-confidence and self-esteem. Some people who have had
the operation say that they also feel physically better following the
procedure. But it is important to know that there is no evidence to
suggest that pectus correction surgery will reduce any problems with
your heart or lungs.
It is important to remember that it is not possible for us to say to what
extent we will be able to improve the shape of your chest with surgery.
Your surgeon will discuss this with you.
Though many people will feel more positive about themselves
following the corrective procedure, many continue to need and
receive counselling and other support for poor self-esteem or concerns
over body image.

What
are the risks of surgical treatment for pectus anomaly?
Overall both the Nuss
and Ravitch procedures have good safety
records. Complications can occur with any surgery, however. For
pectus anomaly correction surgery, the specific risks include:
- Bleeding: Rare
for Nuss procedure; unlikely for Ravitch procedure
- Wound infection:
Rare
- Collection of fluid
around one or both lungs (pleural effusion): Rare
- Air leak from either
lung (pneumothorax): Rare
- Quick healing of
the surgical wound, which results in the scar
being red, thickened and itchy (Keloid scarring): Rare
- Long term discomfort
from the sternal bar: Unlikely
- Damage to the heart
from bar placement: Very rare
