Posters Presented at DDW 2022 Demonstrate G-Tech System Motility Measurements Correlate with Antroduodenal Manometry Measurements and Can be Used to Characterize Colon Motility Alteration

MOUNTAIN VIEW, Calif., May 26, 2022G-Tech Medical, a developer of non-invasive diagnostic solutions for patients with gastrointestinal disorders, today announced that two posters were presented at Digestive Disease Week Conference held in San Diego in from May 21 through May 24.

The first poster, entitled Wireless non-invasive patches detect phase III of the migrating motor complex in response to octreotide administration, reported on a study performed in humans by researchers from the Children’s Hospital of Philadelphia and GTech.  The key finding of the study was that the G-Tech patches detected spectral peaks in myoelectric activity at the same frequencies detected by simultaneous antroduodenal manometry after octreotide administration. These frequencies (11-12 cpm) have previously been associated with small bowel activity.

The second poster, entitled Development and Characterization of an opioid-induced constipation (OIC) model in swine: use of G-Tech wireless non-invasive patches to monitor colonic myoelectrical activity (CMA), reported on a study performed by researchers from UCLA and G-Tech. The study described the development of a valid model of OIC in pigs. The patches demonstrated sensitivity to detect effects of loperamide on the porcine CMA and showed potential to help characterize colon motility alteration as in constipation.

These posters are only the most recent in a series of over 20 posters, multiple invited talks and five peer-reviewed journal articles that demonstrate validity of the underlying measurement of GI motility and its potential for broad, game-changing clinical application.

“We’re extremely fortunate to collaborate with such esteemed partners in the academic community to help move motility science forward,” said Steve Axelrod, CEO of G-Tech.

The G-Tech WPS is a tool that provides gastric and intestinal myoelectrical activity measurements to be used at the discretion of the Physician or Clinical researcher to aid in the diagnosis and evaluation of gastrointestinal disorders and dysfunctions.
