Diverting ileostomy significantly reduces the risk of anastomotic leakage during colorectal cancer surgery, but specific risk factors can complicate outcomes.

• Anastomotic leakage occurred in 17.5% of patients, with lower rectal tumors as the sole significant risk factor (p=0.0095).
• Reoperation due to leakage was necessary for 19% of these cases, particularly in patients with T4 tumors (p=0.022) and stenosis (p<0.001).

Surgeons should weigh these factors carefully when deciding on ileostomy in colorectal cancer surgeries, as some patients may benefit more from alternative approaches.

• High-output stomas were seen in 30%, with outlet obstruction in 15.8%; severe complications in stoma reversal were rare (1.7%).
