MOUNTAIN VIEW, Calif., June 6, 2023 – G-Tech Medical today announced an oral presentation of an abstract entitled Associating Myoelectric Activity Following Colorectal Surgery with Return of Bowel Function at the American Society of Colon and Rectal Surgeons (ASCRS) Annual Meeting held in Seattle June 3-6. Arabella Dill-Macky of Yale authored and presented the abstract. Dr. Ira Leeds of Yale was the principal investigator of the study conducted in collaboration with G-Tech.
The G-Tech Wireless Patch System (WPS) is a non-invasive diagnostic solution that helps physicians assess patient motility by monitoring myoelectrical signals from the stomach, small intestines and colon over multiple days.
In the study, 24 patients who had undergone colectomies or enterectomies with anastomosis were enrolled. Three patches were applied to the patients’ abdomens within 4 hours after surgery, where they remained throughout the hospital stay. The G-Tech app collected myoelectric signals that have been shown to correlate with stomach (2.4-4 CPM), small bowel (5-12 CPM) and colon (12-28 CPM) signatures, along with patient entered information such as first liquid and solid meals and first bowel movement. Patient demographic and clinical information was also collected. Length of Stay for each patient was broken into expected (< 5 days) and late (>5 days) groups.
The small bowel and colon myoelectrical signals had statistically significant differences between the expected and late groups. For the small bowel signal there was significance at 12-, 18- and 24-hours after surgery, and for the colon signal there was significance at 6-, 12-, 18- and 24- hours after surgery.
“The results demonstrate that higher small intestinal and colonic myoelectric activity in the early stages of recovery is associated with a shorter length of stay,” said Dr. Leeds. “Further use of gastrointestinal myoelectric signaling may help inform clinical decisions regarding the discharge of patients even in the first 12 hours after surgery.”
“These results are consistent with our earlier clinical studies of other types of abdominal surgery patients,” said Steve Axelrod, CEO of G-Tech. “Demonstrating that the myoelectric signals can be predictive of recovery time for colorectal surgery patients represents another key finding. We are currently working on several additional studies that are enrolling patients with various other surgery types to further validate that the G-Tech WPS has broad applicability in helping shorten Length of Stay.”
At the ASCRS meeting a poster by Dill-Macky entitled Assessing Views on Myoelectric Activity Data for Discharge Readiness After Colorectal Surgery was also presented. The poster reviewed the opinions of 30 surgeons and surgery residents regarding the most effective methods for communicating timely myolectric signal information to physicians.

G-Tech Medical will be in Chicago in May at the 2020 Digestive Disease Week with two posters in collaboration with researchers at Stanford University.
G-Tech Medical’s Lindsay Axelrod presented her abstract with preliminary findings from an ongoing collaborative study with Stanford University supported by the Helmsley Charitable Trust. The study involves using non-invasive wireless electrode patches to read myoelectrical signals from the gut over 3 days in patients with Crohn’s disease. Forty patients presenting in flare, and 30 in remission will be tested at t=0,1,3 and 6 months.
