Transrectal stent in endoscopic palliative therapy of malignant stenosis of the rectum

To check the feasibility and safety of endoscopic stent introduction in colorectal cancer therapy.

A total of 62 patients with inoperable tumors of the rectum and rectosigmoid were treated by introducing stents. Stents were also introduced in 3 patients with advanced prostate tumors obturating (narrowing) the rectum. In 3 cases, the stents were introduced under X-ray control. In all other cases, an endoscopic approach to the stent introduction was employed.

Stents could not be introduced in 4 patients. In 1 case, the bowel was perforated above the malignant (tumorous) stenosis. In 4 patients, it was necessary to remove the stents because of dislocation. Growth of the tumor into the stent was not experienced. Experience with acute obstruction treatment was minimal as only two patients were treated for this indication.

Endoscopic stent introduction is a safe palliative procedure making it possible to improve the quality of life of patients with inoperable tumors of the rectum and rectosigmoid.
