Ileostomy creation is an excellent approach to prevent leakage in patients undergoing low anterior resection for the treatment of rectal cancer. However, the two major complications of ileostomy are outlet obstruction and high-output stoma, and these complications remain unavoidable postoperative problems of ileostomy.
Risk factors associated with outlet obstruction and high-output stoma were retrospectively analyzed. The study included 83 patients with rectal cancer who underwent surgery. Of these patients, 34 underwent ileostomy creation.
We found that outlet obstruction and high-output stoma were highly related (p = 0.03). Additionally, a thick rectus abdominis muscle and advanced T stage were the common risk factors of outlet obstruction (p = 0.0005 and p = 0.01, respectively) and high-output stoma (p = 0.04 and p = 0.03, respectively).
Our findings suggest that rectus abdominis muscle thickness and advanced T stage are predictive markers of outlet obstruction and high-output stoma.
