A 2.2 mm scope could spot cancerous tissue in minutes, not days
NCT ID NCT07826611
First seen Sep 17, 2026 · Last updated Sep 18, 2026 · Updated 1 time
Summary
Doctors usually send colorectal tissue to a lab and wait days for results. This pilot study tests a miniaturized device called MULTISCOPE that uses light-based imaging to tell healthy tissue from cancerous tissue in real time. Researchers will examine 30 tissue samples removed during standard endoscopic surgery and compare the device's readings against conventional lab analysis. The study also checks whether the device's built-in cold plasma tool can destroy tumor cells.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- MULTISCOPE, a miniaturized optical biopsy device that uses two-photon imaging and cold argon plasma
- What this could lead to
- If it works, doctors could one day get an instant read on whether colorectal tissue is cancerous during a procedure, without waiting days for lab results.
- What could go wrong
- This is a small, early-stage lab study on 30 tissue samples, not on living patients. The device may not match standard lab testing, and results from a controlled lab setting may not hold up in real clinical use.
