Entac_Device Post Op Ileus trial

The purpose of this research is to study the performance of a device called PrevisEA, an investigational device not approved by the Food and Drug Administration (FDA). This research is sponsored by the maker of the PrevisEA device, Entac Medical Inc. This device listens to and records abdominal sounds which provides data that can help predict gastrointestinal impairment (GII). GII is a condition that is defined as the failure of oral re-feeding after abdominal surgery. This happens when any of the following events happen beyond 24-hours after abdominal surgery; • Vomiting • The need for your doctor to reverse the diet • The need for your doctor to place a nasogastric (NG) tube in you. A NG tube is a flexible rubber or plastic tube that is placed through the nose and down into the stomach. It can be used to carry food directly to the stomach.
