Treatment
Endoscopic decompression treats spinal stenosis — a narrowed nerve corridor — by removing the overgrown bone and thickened ligament pressing on the nerves, through a keyhole portal that largely preserves the muscles. If your walking distance has been shrinking and surgery is on the table, you're probably carrying some worries too. Good. Let's answer them properly, starting with yours.

Spinal stenosis squeezes the nerves that run your legs — and endoscopic decompression un-squeezes them with the smallest possible footprint. Through a portal about a centimetre wide, a high-definition camera enters the narrowed canal and shows the surgeon exactly what is pressing on the nerves; fine instruments then remove the overgrown joint edges and thickened ligament — millimetre by millimetre, under direct vision — until the corridor is open again. The muscles that support your spine stay largely where they belong. The goal is simple to state and life-changing to feel: legs that walk further again.
The incision, to scale
Figures reflect ranges reported in published series for suitable patients — our specialist will discuss the numbers that apply to your spine, openly, before anything is decided.
When spine surgery is suggested, the questions tend to arrive at night. Tap the loudest one — we'll answer it straight.
Almost certainly not — and that comparison is the honest place to start. This operation exists to end pain, not add to it; it also replaces a far more invasive route. Traditional open laminectomy reaches the canal by stripping muscle from the spine over a 5–8 cm incision; the endoscopic route slips between the muscles through a centimetre-wide portal instead. During the procedure you feel nothing — anaesthesia is planned with you and for you, with your age and health individually assessed. Afterwards, there is simply less disturbed tissue to hurt: wound soreness is typically modest, managed properly, and fading within days.
And the pain that matters most — the leg pain, heaviness and cramping that stenosis inflicts — is what the operation exists to relieve. Many patients notice their legs feeling freer early, then watch the improvement build as they rebuild their walking.
The fair answer takes the question seriously: all surgery carries risk, and anyone who waves that away doesn't deserve your spine. For endoscopic decompression the recognised risks — infection, bleeding, a spinal fluid leak, nerve injury, or symptoms persisting — are uncommon, and we discuss each openly, with your numbers, before anything is decided.
Now the other half: what stands between you and those risks. An MRI-confirmed diagnosis, matched against your walking story, so we operate only where the compression truly is. A senior spine surgeon with three decades of practice. A major hospital — Mount Elizabeth Novena — around the operating room, with an anaesthesia team that assesses older patients individually and honestly. And a technique designed to disturb as little as possible on the way to the problem. Small risks, taken seriously, discussed openly — at any age.
Most patients walk the same day and are home the same day or after one night — then the real project begins: winning back the distance stenosis took. Short, frequent walks grow steadily longer; physiotherapy rebuilds strength and confidence; daily life returns in weeks. Wherever you are in the journey, here's what that stage looks like:
The considering stage is for questions — bring all of them. A consultation reviews your scans against your walking story, lays out keyhole surgery versus continued conservative care with honest odds, and leaves the decision where it belongs: with you. Bring existing MRIs and X-rays; comparison is gold.
Preparation is mostly practical. Clear instructions on eating, medication and arrival; a lift home and a light few days planned; comfortable walking shoes ready — they're your rehabilitation equipment. Most patients need far less “recovery setup” than they expect. Questions before the day? Message us.
Recovery is measured in walking distance — build it patiently. Walk early and often, growing the distance week by week; skip heavy lifting and deep bending until cleared; let physiotherapy set the pace. New weakness, numbness, fever or wound concerns? Contact us promptly — that's what the hotline is for.
At the decompressed level, relief is usually lasting — the bone and ligament removed don't grow back the way they came. The honest caveat is different: stenosis is a wear process, and other levels of your spine keep ageing at their own pace. Pretending otherwise would be selling, not informing. What tilts the odds your way: the conditioning and walking you rebuild after surgery, weight kept in a healthy range, and sensible follow-up — so if another level ever narrows, it's caught by calendar rather than by crisis. We don't just reopen the corridor; we help you keep it open.
The most important question on the page — because plenty of spinal stenosis is managed well without an operation: conditioning on the bike and in the pool, flexion-based physiotherapy, and targeted image-guided injections win back real distance for many. Surgery earns its place in specific situations — check yours:
You fit the profile this procedure was designed for. That doesn't make surgery inevitable — it makes a proper surgical consultation worthwhile: reviewing your scans against your walking story, confirming the compression is truly the culprit, and weighing keyhole decompression against continuing conservative care.
Good news — you may not need surgery at all. Plenty of stenosis is managed with conditioning and targeted treatment, and that's the path we'd start you on. An assessment maps your narrowing, your symptoms and your options — with surgery staying exactly where it belongs: in reserve.
And remember: a consultation is not a commitment to surgery — it's how you get the information this page can't know about your spine.
Tap the one that sounds like you — and get the straight answer:
Both create room for compressed nerves in a narrowed spinal canal. A traditional laminectomy opens the back through a sizeable incision and removes the lamina — the bony roof — often stripping muscle to get there. Endoscopic decompression achieves the same goal through a portal about a centimetre wide: a camera enters the canal and precisely removes only the overgrown bone and thickened ligament doing the compressing, leaving the muscles and most of the structure intact. Less collateral disruption, faster mobilisation — in suitable cases.
Most patients are walking the same day and home the same day or after one night. The weeks after are about rebuilding what stenosis took: short, frequent walks growing steadily longer, physiotherapy for strength and confidence, and a gradual return to daily life. Many notice their legs lasting longer within the early weeks — walking distance tends to build progressively from there.
Age alone is rarely the barrier — spinal stenosis is a condition of later life, and this operation is routinely performed for patients in their seventies and eighties. What matters is overall health, which the anaesthesia team assesses individually before anything is scheduled. In fact, it's often older patients — whose walking has shrunk the most — who gain the most.
Usually not. Decompression alone treats most stenosis — fusion is added only when the spine is genuinely unstable at that level, most commonly with a slipped vertebra (spondylolisthesis). Your standing and bending X-rays answer the stability question before surgery, so you'll know exactly what's planned and why — no surprises in the operating room.
It removes the compression at the treated level — and for most well-selected patients the relief is real and lasting. Honest caveat: stenosis is a wear process, and other levels of the spine keep ageing. That's why the operation comes packaged with conditioning, weight management and sensible monitoring — protecting both the result and the rest of your spine.
