This looks across many earlier studies rather than running a new one.
This looked back at records of people who already had surgery, so it did not test anything new.
The short version
For these rare brain tumors, open surgery and smaller keyhole surgery gave similar results.
What was studied. Researchers pooled 361 studies covering 1500 patients who had surgery for tumors inside the brain's fluid spaces. They compared open skull surgery with less invasive methods that use a scope or a small tube.
What they found. Most patients had open surgery. Surgeons removed all of the tumor in 67% of open cases, 46% of scope cases, and 76% of tube cases. About 65% of patients needed a permanent drain for brain fluid. Fluid buildup before surgery was the main thing linked to needing that drain, not the type of surgery.
What this means, and what it doesn't
What it could mean: Both ways of operating appear to work about as well. A surgeon can pick the approach that best fits the tumor. Someone with fluid buildup before surgery may still need a permanent drain.
What it doesn't mean: This does not mean one surgery is better than the other. The study only pooled records of past patients. It did not test the two methods side by side in a planned trial. Far fewer patients had the less invasive surgery, so less is known about it. This is not a new treatment and not a cure.
