There are many
examples of situations where surgery is required to save the
patient’s life. There is an entirely separate category of
surgery, though, that does not qualify as “necessary”.
Those surgical procedures that are undertaken by choice are
termed elective surgery. In other words… elective surgery is
optional. It does not have to be done to save or stabilize
the patient’s life.
We all are familiar with the common elective surgeries done
on humans… liposuction, face lifts, skin tag removal are
just a few. And in dogs, ear cropping, spay/neuter surgery,
tail docking, come readily to mind. Most people agree that
ear cropping is a cosmetic procedure with little verifiable
medical rewards for the dog. There’s a vast gray area
though, where a dog owner needs to carefully consider the
choice to proceed with a surgical procedure because there
are many elective surgeries that, although may not be
considered life-saving, still provide health-enhancing
benefits.
The patient with
fat deposits exemplifies the dilemma dog owners and
veterinarians face regarding the decision to do or not do
surgery. Many veterinarian recommend removing fat deposits,
called lipomas, once they reach a certain size because if
left to their own whims these fatty growths sometimes
enlarge to huge proportions. But which fat deposits can be
left alone and which should be removed? Even if probed and
analyzed by needle biopsy and shown to be benign, some fat
deposits simply do not stop growing!
And what are the
risks versus benefits of a procedure? Let’s take as an
example dental procedures. If loose teeth, gingival growths
and deep infections are present, a case could be made that
the dental procedure really needs be done to improve and
safeguard the patient’s quality of life. The down side is
that, because these elective procedures require some form of
anesthesia and surgical invasion of the patient, they are
not entirely without risk. With modern veterinary medical
presurgical protocols, though, the attendant risks can be
minimized; and one important tool in identifying the “at
risk” patient is the blood chemistry profile assessment.
Most
veterinarians believe pre-anesthetic blood screening before
any surgery is important. While most healthy animals are at
minimal risk for complications during an elective surgery
such as a neuter or spay, there is always the chance that an
animal could have an underlying problem that might not
manifest itself until the animal is put under anesthesia.
Surgery is not a good time to discover that there is a heart
or liver problem.
Veterinarians will
discuss the “risk versus benefit” topic with the pet’s
owner, and relate the ways to reduce risk and maximize the
benefit before any elective surgery is performed. In many
situations the timing of the surgery is critical. |

Cancer surgery, if done
early, may have rewarding benefits long term; but if
indecision delays the procedure the benefit of surgery may
be undermined. Orthopedic problems such as torn ligaments,
fractures, cartilage damage and the ravages of progressive
arthritis are time critical… irreversible degeneration
awaits whenever corrective or reconstructive surgery is
delayed.
Timing of an elective orthopedic surgery revolves around
several factors. In general, the sooner an orthopedic
problem is corrected the less long term, untreatable
degeneration can occur. Regarding many tumors, lipomas and
cysts, excision early surgical intervention can be
important.
A veterinary
orthopedic surgeon remarked "If the surgical repair will be
effective regardless of duration of the problem, the
decision to go to surgery depends on the severity of
clinical signs and how badly the animal’s quality of life is
affected. An example of this is total hip replacement for
dogs with hip dysplasia. Regardless of the degree of
arthritic change, within reason, an artificial hip is likely
to be successful since the arthritic joint is actually being
replaced.
We never
encourage clients to have a total hip replacement performed
on their dog unless the clinical signs are significant.
However, if we determine a hip replacement is warranted, we
prefer to proceed with surgery sooner rather than later. Why
make the dog live with an uncomfortable or painful hip for
an extra year when a total hip replacement yields almost
immediate and excellent results?”
Pet owners always
have to consider the expense, whether the problem is
negatively affecting the animal’s quality of life and
whether the problem is likely to worsen to the point that
surgical repair will be significantly less effective. And
regarding the anesthetic factors, in generally healthy
animals anesthesia risk is minimal with today’s anesthetics
and monitoring equipment. It always is helpful to do a
presurgical blood chemistry evaluation.
Based upon
information gathered regarding the pros and cons of the
situation, the ultimate choice to proceed rests with the dog
owner. Will the expected goal of the surgery weighed
against the required anesthesia and chances for success of
the procedure be worth the associated risks? Should your
dog be spayed? Should that bump be removed before it
progresses into a life threatening cancer? Does that bad
breath indicate a dental procedure is needed? The right
answer to these kinds of questions is achieved through
understanding the risks and weighing them against the
benefits… and acquiring patient data. And even though the
decision to proceed may not be as clear cut as life-saving
emergency surgery on a dog run over by a logging truck, you
will nevertheless have the confidence that you did the right
thing to improve or ensure the quality of life for your dog
or cat. |
