Company Spotlight: Iterative Health SKOUT - Live polyp detection with 0ms delay

This episode examines the FDA 510(k) summary for Iterative Health's SKOUT system, a computer-aided detection tool that places a blue bounding box around potential colorectal polyps in real time. We unpack the technical specs, the zero-millisecond video delay, the predicate device comparison, and what key performance data is missing from the public clearance document.

Key points

• The SKOUT system is cleared as a Class II software device to assist gastroenterologists by highlighting suspected colorectal polyps with a two-dimensional blue rectangular outline during white light colonoscopies.
• The FDA clearance (K253664) is based on substantial equivalence to an earlier version of the SKOUT system (K251126), not on a new standalone clinical trial.
• The software features smart pausing, disabling the polyp detection marker when an endoscopic surgical tool enters the frame or if lighting is inadequate.
• Bench testing reported a video delay due to the device and marker annotation of exactly 0ms, with a minimum resolution of 1.1ms.
• The updated software was retrained for compatibility with Endocuff devices, multiple polyps, and sessile serrated lesions, aiming for a reduced false positive rate.
• While the summary notes that performance testing evaluated true positives and false positives on an expanded dataset, it does not disclose the actual dataset size or the accuracy percentages.
