This was tested in people. That is the most reliable kind of research we share.
These surgeries are already done in children today, but this was just one hospital looking back at its own records.
The short version
Doctors drained trapped brain fluid and took a tumor sample in one surgery, and it went well for most children.
What was studied. Doctors reviewed the records of thirty-five children treated at one hospital from 2013 to 2024. Each child had a tumor blocking brain fluid, and in 12 cases (34.3%) doctors also took a tumor sample during the same surgery.
What they found. The fluid surgery worked in 29 children, or 82.9%. Problems after surgery happened in 7 children (20.0%), most often fluid leaking from the wound in 3 of them. Useful tumor samples came back from 10 of 12 children who had a biopsy.
What this means, and what it doesn't
What it could mean: If a child needs surgery to free up trapped brain fluid, the care team may be able to take a tumor sample at the same time. That can give answers about the tumor sooner. It may also mean one less operation later.
What it doesn't mean: This does not mean the surgery treats the tumor itself, and it is not a cure. It only helps with the trapped fluid and with getting a diagnosis. This was one hospital looking back at its own past records, not a trial that compared treatments. Results could look different somewhere else. What is right for one child is still a decision for their own care team.
