Laser spine surgery, a fool and his gold

A patient called me recently asking for a referral letter to travel to Dubai for surgery. Apparently, I had seen the patient a few years ago, offered spine surgery, which was accepted and then the patient failed to turn up.

It seemed the fear of spine operations in Nigeria and the need for a second opinion led to an interesting decision. The decision was made to travel to Dubai for Laser Spine Surgery or as some also call it, ‘bloodless surgery’.

Hence the phone calls asking for me to write a referral letter.

Laser Spine Surgery
I am now frequently being asked by patients, if their spine surgery can be done with laser. There is a perception by some Nigerians that laser spine surgery is a new, modern, high tech, low risk, futuristic technology. The reality is far from the truth. Lasers have been around for a long time and are almost completely useless when it comes to real spine surgery.

Spine surgery that has good long term outcome!

What is laser?
A laser is a light beam that can be focused on a very small area. The ‘light’ heats cells in the area being treated until they “burst.” There are several types of lasers and each has specific uses. Types of lasers include the carbon dioxide (CO2) laser, the YAG (yttrium aluminum garnet) laser, alexandrite, KTP, and the pulsed dye laser.

A laser (focused beam of light) can be used for cutting soft tissue. In eye surgery, they are definitely useful and have been used to treat glaucoma. They are also used for treating the lens in our eyes in corrective lens surgery. This helps to avoid wearing glasses in some people with short or long sightedness.

Laser is also useful in treating some cancers, abnormal blood vessels and kidney/bladder stones. Laser is a relatively popular and non-invasive method of haemorrhoidectomy (treatment of piles). It may also be used to remove wrinkles, tattoos, birthmarks and to treat some skin diseases.

Colonial mentality
Lasers are now perceived as an effective treatment for spine diseases because of two reasons: the obvious placebo response, and the tendency to always think the second opinion (read: white skin!) is more knowledgeable.

A patient once called a hospital in Abuja and asked them, ‘I hope you have white doctors in your hospital?’ Apparently, he did not want to get there and have to see a black (Nigerian) doctor. Sadly, of course, this was before the scandal broke that the hospital was using junior doctors and others pretending to be fully trained specialists.

Anyway, to the matter at hand.

Spine surgery
Lasers cannot cut bone so they cannot be used to treat patients with narrowing of the spine. It cannot be used to treat patients with degeneration of the joints in the spine: a common cause of back pain. Lasers can cut or burn the disc (the shock absorber between bones in the spine). This is for patients with sole disc disease which may lead to shrinkage of the disc and resolution of the problem.

But, it is far easier and more reliable to just simply grab the disc yourself and remove it from where it is compressing the nerve. Also, since discs lie right next to the nerve, one risks the chance of damaging the nerve with the laser. Physically protecting the disc through an open operation is perhaps a better option. This is the preferred option of most spine surgeons.

Laser cannot be used to treat many real spine problems.

Just business
It seems that the most practical use for lasers in spine surgery is for marketing. Like most businesses, spine surgery is very competitive, and having an edge in marketing can make a practice standout. Many of the foreign hospitals touting laser spine surgery use it to attract unsuspecting customers. The laser will be of little or no useful function during the surgery.

Hence, at the major spine meetings and in the major spine journals there is a paucity of (if any) articles documenting any use of lasers in spine surgery. Articles on laser spine surgery are few and far between as it is not an accepted spine treatment procedure.

Designer operations
In conclusion, spine surgery is an individual thing. Operations are designed specifically for each patient and what Joe had may not be suitable for Adamu. Operations are often designed to achieve one of two results: remove pain or to free the nerve from compression. The pain may be coming because of pressure on the nerve or instability of the bones.

So, operations may be to free the nerves or to fix the bone or both. More often than not, the surgery will involve cutting of the skin to get to the bones or nerves. You can do that through a tiny hole (minimally invasive: using a microscope or by using special tubes and cameras) or through a hole wide enough for a surgeon and his assistant to climb into.

What do you care, so long as the job is done and you are free of pain!

A fool and his gold
So, my patients hankering after laser spine surgery do need to be careful they do not waste their money. Many unscrupulous doctors especially in private practice abroad use tricks and false promises to ensnare the fool and make him part with his gold.

Our colonial mentality helps to facilitate the enslavement.
