Analysis reveals that stenosis and T4 invasion increase reoperation risk due to anastomotic leakage after ileostomy in colorectal cancer patients, suggesting more careful consideration.

Due to small number of AL patients requiring reoperation, the finding is exploratory. However, in patients with stenosis and T4 invasion, the merits of ileostomy might be restricted.
