- Tested in people
This was tested in people. That is the most reliable kind of research we share.
Doctors only looked back at past patients at one hospital, with no group to compare against.
The short version
Surgeons used a small patch to close an opening made during brain tumor surgery.
What was studied. Doctors looked back at records of 32 adults who had surgery for a fast growing brain tumor. During surgery an opening was made into a fluid space in the brain, and a patch was placed over it.
What they found. Fluid collected under the skin or leaked from the wound in 5 of 32 people. This happened within 30 days of surgery. Four of them got better without more surgery, and one needed a drain for a short time. No one got a brain infection or needed a lasting drain for brain fluid. Scans through 3 months showed the patch stayed in place and fluid still flowed.
What this means, and what it doesn't
What it could mean: This suggests the patch may be a workable way to close the opening. It is one choice a surgeon may use during this kind of surgery.
What it doesn't mean: This does not mean the patch works better than other ways to close the opening. There was no comparison group, so nothing was tested side by side. Doctors only looked back at past records at one hospital. Follow up was short, so late problems are still unknown. This is not a treatment for the tumor itself, and it is not a cure.
