This study was a multicenter, retrospective cohort study. Although advancements in surgical techniques have mitigated the incidence of intestinal anastomotic fistula, complete avoidance remains elusive. Anastomotic leakage (AL) complications directly impinge on postoperative quality of life and pose life-threatening risks if inadequately managed. Given AL's adverse prognostic implications and the financial strain on patients' families, identifying its risk factors aids in perioperative risk assessment, enabling timely clinical decisions on interventions to enhance prognosis and curtail adverse outcomes and economic investments.
