This study will measure the accuracy of a disposable, non-invasive device for the continuous monitoring of abdominal sounds, called the AGIS sensor (Acoustic Gastro-Intestinal Surveillance) in predicting patients' intolerance to feeding (defined as severe nausea, vomiting, or need to place a nasogastric tube within 4 hours of initiating a standard feeding protocol) following abdominal surgery. This will be a pragmatic, observational study.
