Peranal dilatation of a postsurgical colonic stenosis by means of a flexible endoscope.

Colonic stenosis following resection and end-to-end-anastomosis of the colon is observed in 2-5% of all patients. The authors report that a patient with repeated episodes of colonic stenosis after resection of the sigmoid was successfully treated with an Eder-Puestow dilatator by means of a flexible endoscope.
