Core Tip

Core Tip: It remains unclear whether the benefits of low ligation of the inferior mesenteric artery (IMA) during sigmoid colon and rectal cancer surgeries extend to improved genitourinary and defecatory function. We conducted this meta-analysis to compare low ligation and high ligation of the IMA in terms of functional outcomes, as well as other surgical and long-term survival outcomes.
