Core Tip

Core Tip: This retrospective cohort study developed a nomogram to predict technical difficulty prior to laparoscopic sphincter-preserving radical resection for rectal cancer. Significant predictive factors were identified through multivariate logistic regression, including the surgical approach using laparoscopic intersphincteric dissection, intraoperative preventive ostomy, the sacrococcygeal distance, and the anterior-posterior diameter of pelvic inlet/sacrococcygeal distance. The nomogram’s clinical value lies in enabling surgeons to preoperatively evaluate expected difficulty and customize surgical approaches accordingly. It aids in individualized surgical planning.
