In this study, we aim to measure gut myoelectric activity in the perioperative course using external patches in an animal model.<h4>Methods</h4>Four external patches were placed on the abdominal skin of female Yucatan pigs to record gastrointestinal myoelectric signals for 3 to 5 d. Pigs subsequently underwent anesthesia and placement of internal electrodes on stomach, small intestine, and colon. Signals were collected by a wireless transmitter. Frequencies associated with peristalsis were analyzed for both systems for 6 d postoperatively.<h4>Results</h4>In awake pigs, we found frequency peaks in several ranges, from 4 to 6.5 cycles per The Journal of surgical researchPerioperative Gastrointestinal Myoelectric Activity Measurement Using Wireless External Patches.PMC11490404OT2 OD026577R01 DK130972Salimi-Jazi FAxelrod SNavalgund ARafeeqi TThomas ALDunn JCYWood LSYAxelrod LfalsePerioperative Gastrointestinal Myoelectric Activity Measurement Using Wireless External Patches.<h4>Background</h4>Stomach, small intestine, and colon have distinct patterns of contraction related to their function to mix and propel enteric contents.
