Who is a candidate?
Biportal endoscopic decompression may be an option for selected patients with a herniated disc or spinal stenosis causing nerve compression. Candidacy depends on the location of compression, spinal stability, previous surgery, symptoms, examination, and imaging, not simply the size of an incision.
How the procedure works
The technique uses two small portals: one for a high-definition camera and continuous visualization, and another for specialized instruments. This gives the surgeon an illuminated view of the anatomy while working through a muscle-sparing corridor to remove the tissue pressing on a nerve. In selected cases, an endoscopic approach may also be used as part of a fusion procedure.
Recovery
Many decompression procedures are performed in an outpatient setting. Walking begins soon after surgery, with a gradual return to activity. Recovery varies with the diagnosis, the procedure performed, overall health, and the demands of work or sport. Smaller portals may reduce tissue disruption, but they do not eliminate normal healing time or surgical risk.
Risks
Small portals reduce how much muscle is disturbed, but they do not remove surgical risk. General risks include infection, bleeding, and the risks of anesthesia. Risks particular to this approach include a tear in the lining around the nerves with leakage of spinal fluid, irritation or injury of a nerve root, and decompression that turns out to be incomplete, which can mean a second procedure or conversion to an open operation during the same anesthetic.
The technique uses continuous fluid irrigation to keep the view clear, and pressure from that fluid is a consideration specific to endoscopic surgery. A disc can also herniate again at the same level after a successful decompression. Dr. Adapa will go through which of these matter most in your case before you decide.
Benefits and alternatives
Potential benefits include direct visualization through small portals and less disruption of surrounding muscle. Alternatives may include physical therapy, medication, injections, tubular decompression, open decompression, or decompression with fusion. The best option is the one that adequately treats the problem while preserving healthy anatomy when possible.
