Core Tip
Core Tip: This single-center retrospective study investigated and analyzed the incidence and risk factors for prolonged postoperative ileus (PPOI) in geriatric patients with colorectal cancer following laparoscopic radical resection. A more comprehensive and accurate risk stratification model for PPOI was developed by jointly assessing the patients' global functional status and modifiable clinical indicators, which provided empirical evidence to support the development of individualized and precise perioperative management in the future. For elderly patients, optimizing perioperative evaluation and management protocols is crucial to reduce the incidence of PPOI and promote postoperative recovery.
