Summary
This study tests a new device called Napoleon, a tiny catheter with a ruler, to measure the size of the stomach-connection opening in people who have regained weight after gastric bypass surgery. Doctors will compare measurements taken with the device to their usual visual estimates. Up to 100 patients will take part, and the goal is to see if the device is easy to use and gives more consistent results.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Napoleon device (a small catheter with a ruler for measuring)
What this could lead to
If successful, this could give doctors a more accurate way to measure the stomach connection, potentially guiding better treatment for weight regain after gastric bypass.
What could go wrong
This is an early feasibility study with only 100 participants, so results may not apply to everyone. The device is used off-label, and its benefit over simple visual estimation is not yet proven.
