Evolution colonic stent as a bridge to surgery


Indication for procedure

The laparoscopic resection of colorectal carcinomas is, more and more, replacing open surgery. This minimally invasive method shows equal oncological results with less perioperative pain, a better cosmetic result, and a shortened period of recovery. A contraindication for the laparoscopic procedure is an ileum with dilated intestinal loops, because of an increased risk for perforation. Here, a preoperative stenting with colorectal metal stents offers the opportunity to relieve the ileus and to perform a minimally invasive resection later.

About the author and facility

For the past 17 years, Dr. Michael Hünerbein has performed all current endoscopic examinations and interventions, including gastroscopy, colonoscopy, and ERCP. The Helios-Hospital Berlin has longstanding experience in stenting, including colorectal stents. The hospital is certified as a reference center for surgical endoscopy by the German Society of Surgery.

Device and accessories

A standard colonoscope and a fluoroscope are used in this procedure. For the x-ray image, a water-soluble contrast is used. The stenosis is probed using a guide wire with a hydrophilic tip. Over the wire guide, an uncovered Evolution Colonic Controlled-Release Stent (available in lengths of 6, 8, or 10 cm) is pushed through the stenosis. The distal end of the stent is deployed and the positioning rectified, as the situation requires. When positioned correctly, the stent can be fully deployed.
