Pilot Study for Evaluation of the Need for Protective Ileostomy After Low Anterior Resection Due to Rectal Cancer
Since introduction of total mesorectal excision prognosis and quality of life of patients
with rectal cancer of the middle or lower third of the rectum could be improved
significantly. There is no valid data about the need of protective ileostomy in these
patients. About 10% of the patients develop insufficiency of the anastomosis and might
benefit from ileostomy whereas about 90% would not have required protective ileostomy
retrospectively. Aim of the study is to show that protective ileostomy is not required if
several criteria are fulfilled and early measures in case of clinical impairment are
defined. Therefore eligibility criteria include safely performed stapler anastomosis with
complete rings and control of impermeability by air insufflation. In the event of clinical
impairment in the postoperative course CT scan with KM filling of the rectum to exclude
insufficiency of the anastomosis will be performed. In case of insufficiency protective
ileostomy will be created. 40 patients will be included.
Comparison: Patients with resectable rectal cancer of the middle or lower third will be
intraoperatively randomized to either protective ileostomy or no ileostomy at all.
