Colorectal Stenting

Intestinal stenting is a procedure that is rapidly coming into more widespread use. It is reported to be a safe and highly effective alternative in patients with unresectable intestinal obstruction. Recent reports show the value of this procedure in colorectal obstruction, as it is relatively safe and can avoid the need for high-risk emergency laparotomy and resection in two sessions. New stents can be inserted in a one-step procedure, with delivery through the scope during the initial diagnostic endoscopy. If examinations show that curative treatment is not possible, resection can be completely avoided, so that the initial stent already forms part of the palliative strategy. Although stents are expensive, the procedure appears to be cost-effective, since emergency surgery can be avoided in patients with acute bowel obstruction, and in those with advanced disease no resection of the colon is necessary.
