Clinical analysis of anastomotic fistula after anal preservation in 358 cases of rectal cancer and construction of risk prediction model: a single-center retrospective study.

Objective: To develop and validate a simple prediction model for postoperative anastomotic leakage (AL) in patients with rectal cancer who underwent Dixon surgery by combining preoperative and intraoperative risk factors.

Methods: We conducted a retrospective study on 358 patients who underwent Dixon surgery for rectal cancer in the Affiliated Hospital of Youjiang Medical University for Nationalities (Guangxi Zhuang Autonomous Region, China). Based on logistic regression, the prediction model of AL after Dixon surgery was established and verified.
