Core Tip
Core Tip: This study aimed to identify key risk factors associated with achieving tumour resection and sphincter preservation in patients with rectal cancer by analysing clinical data from 179 patients who underwent laparoscopic radical rectal cancer surgery. Patients with nerve invasion, mucinous adenocarcinoma, and tumours in the lower to middle rectum were at higher risk of sphincter non-preservation. Logistic regression analysis identified nerve invasion, mucinous adenocarcinoma, and tumour height as independent risk factors for sphincter preservation. Conversely, sphincter preservation rates were higher among patients with concomitant colonic polyps. These findings provide valuable insights for identifying high-risk patients and guiding targeted interventions and preoperative evaluations.
