Core Tip
Core Tip: Postoperative recovery of gastrointestinal function in patients with gastric cancer (GC) is crucial. However, it is frequently delayed by prolonged postoperative ileus, leading to increased hospital stays and economic burdens. Effective monitoring of postoperative gastrointestinal recovery in patients with GC remains challenging due to the lack of noninvasive methods. This study investigated risk factors for delayed postoperative bowel function recovery and evaluated bowel sound indicators collected via an intelligent auscultation system to guide clinical practice.
