Low Ligation of IMA Enhances Survival in Rectosigmoid Surgery

Low ligation of the inferior mesenteric artery improves outcomes for rectal and sigmoid cancer patients.

Low ligation significantly boosts 5-year overall survival (HR 0.69, p = 0.026).
It reduces anastomotic leak rates (OR 0.71, p = 0.050) without affecting disease-free survival or lymph node yield.
No increase in overall complications, operative time, or blood loss was observed.

This supports low ligation as the preferred technique in rectosigmoid cancer surgery for better patient outcomes.
