Exero reports pivotal xBar data in colorectal surgery

Exero Medical said its pivotal multicenter study found that its investigational xBar monitoring system detected anastomotic leaks after colorectal resection surgery earlier than standard clinical practice. In data presented at the American Society of Colon and Rectal Surgeons’ 2026 annual meeting, the company reported results from 222 patients, with xBar showing 100% sensitivity and 88% specificity by post-operative day 3, and identifying leaks more than three days earlier on average than usual detection methods. xBar uses sensors embedded in a standard surgical drain to capture electrophysiological data from the surgical site, and Exero said it has submitted the results to the FDA as part of a De Novo application, targeting U.S. market entry in 2027.

Why it matters: For veterinary professionals, the story is less about immediate clinical adoption and more about where post-operative monitoring is heading. Anastomotic leaks remain one of the most serious complications in colorectal surgery, with published literature describing meaningful effects on morbidity, mortality, length of stay, and cost, while leak rates have remained stubbornly difficult to reduce. A system that continuously monitors healing at the surgical site, rather than waiting for clinical deterioration or imaging, points to a broader shift toward earlier detection and more data-driven post-op care that could eventually influence surgical monitoring expectations across species and settings.

What to watch: Watch for FDA review of Exero’s De Novo submission, peer-reviewed publication of the pivotal data, and whether the company expands xBar into additional gastrointestinal indications. (prnewswire.com)
