Abstats™ consists of a disposable plastic device embedded with a microphone that adheres to the abdominal wall and connects to a computer measuring acoustic event rates. The monitor will be placed on the patient's abdomen 30 minutes prior to surgery in the preoperative holding area to obtain baseline intestinal rate. The monitor will be removed prior to surgery and replaced by the surgical team in the operating room and maintained until postoperative day 3. Daily intestinal rate will be calculated as mean and median acoustic events per minute. The raw data will be analyzed by an investigator blinded to the clinical data. Intestinal rates of patients offered immediate solid feeds will be compared with those offered clear feeds. In addition, patients not tolerating or consuming early solid meal will be compared with those who do to identify whether Abstat™ can be an early predictor of diet intolerance in patients undergoing colorectal surgery.
