Micro-Lumbar Discectomy: What You Should Know.



Micro-Lumbar Discectomy: What You Should Know.
July 16, 2018

When your lower back just won’t stop hurting and a variety of non-surgical treatments fail to ease the pain, a micro-lumbar discectomy, also called an endoscopic lumbar discectomy, may prove to be the most effective remedy, according to Kaixuan Liu, MD, PhD, founder and president of Atlantic Spine Center.

Lower back pain affects 8 in 10 adults at some point in their lives, so it’s not an unusual condition. But some cases don’t respond to “conservative” treatments such as pain relievers, physical therapy, ice, heat, or rest, Dr. Liu explains. When that happens, however, it may be due to a herniated disc in the lumbar spine region – the lowest part of your spine, just above the tailbone. When a spinal disc is herniated, its contents are protruding from its tough outer shell and pressing on surrounding nerves. This situation can lead to severe pain as well as neurologic symptoms such as tingling and numbness in the legs. In extreme cases, the disc herniation can lead to paralysis or loss of bladder or bowel function, Dr. Liu notes.

“Years ago, surgery for a herniated disc necessitated a big incision and a long hospital stay, not to mention a lot of post-surgical pain,” he says. “But micro-lumbar discectomy avoids all that. It’s now the most common surgery performed to remove a portion of a herniated disc, and it works exceedingly well without all the risks of open surgery.”

What’s involved in micro-lumbar discectomy?

The name of this procedure is derived from the words micro, meaning small; lumbar, meaning the lower back; and discectomy, meaning removal of the protruding disc portion. What really sets this surgery apart from an “open” procedure is how it’s done using a special endoscopic surgical tool with an attached microscope so surgeons can see the area around the spine without creating large incisions. Performing only a tiny incision over the affected area, surgeons pull back muscles and soft tissues around the spine without unnecessary cutting. After the problem disc is revealed, small tools are used to remove protruding disc material. A few strong stitches close the surgical area, with special surgical glue often used to close the skin.

“The whole micro-lumbar discectomy procedure takes about an hour,” Dr. Liu explains. “While patients are asleep during the surgery, generally they can go home within a few hours and are quite comfortable afterward. Best of all, the surgery is highly successful, healing the disc herniation and related symptoms for between 90% and 95% of patients.”

Dr. Liu’s Tips on Recovery:

One of the best parts about micro-lumbar discectomy is how fast patients see results, Dr. Liu notes. “Within weeks after surgery, if not sooner, symptoms that had plagued back pain patients for months, such as pain, weakness and numbness, usually improve greatly,” he says.

What else can you expect as you recover from an endoscopic discectomy? The complication risks of this minimally invasive surgery are small, so infection, bleeding and other problems don’t typically occur. But it’s still important to take precautions to promote recovery, such as avoiding lifting heavy objects, sitting for long periods, or bending or stretching too much. Additionally, physical therapy is often prescribed to ease pain, strengthen muscles and tissues, and get patients fully back to normal.

“Typically you can go back to work in a week or two, go back to sports and other major activities in 4 to 6 weeks, and lift heavier objects in 6 to 8 weeks,” Dr. Liu says. “But it’s safe to say that within a very quick period, most patients feel like their old selves again, with lower back pain a distant memory.”
