Morbidity and costs of diverting ileostomy in transanal total mesorectal excision with primary anastomosis for rectal cancer.

Morbidity and associated costs after diverting ileostomy are high. The incidence and morbidity of anastomotic leakage was not reduced by creation of an ileostomy. Omission of a diverting ileostomy after TaTME could possibly result in a reduction in treatment associated morbidity and costs.
