The Value of Bowel Sounds in Evaluating Postoperative Intestinal Function Recovery in Colorectal Cancer Patients

This study enrolls patients scheduled to undergo curative surgery for colorectal cancer. Bowel sounds will be assessed preoperatively and postoperatively. By comparing intraoperative variables, the incidence of perioperative complications, reoperation rates, and postoperative outcomes-including time to first flatus, resumption of oral intake, and occurrence of intestinal obstruction-this study aims to investigate the association between perioperative bowel sounds and postoperative recovery, and provide evidence-based support for the clinical application of bowel sound monitoring.
