Metallic stenting for colorectal obstruction.

Intestinal obstruction is a major complication of colorectal cancer. Acute surgical decompression frequently requires subsequent operative interventions and is associated with mortality in more than 3% of the cases. Transanal metallic stenting is now possible to perform on an outpatient basis, thus providing quick symptom relief and the opportunity to cleanse the bowel for work-up or surgery. This stenting provides temporary relief for patients and is gaining acceptance rapidly. Randomized controlled trials are needed to help pinpoint refinements that can minimize the difficulty of stent insertion.
