Enteral stents for the management of malignant colorectal obstruction

Figure 1 Through-the-scope approach has been shown to be safe and effective both in right-sided and left-sided colonic lesions. A: The patient presented with an obstructing colon cancer who was evaluated for an endoscopic colonic stent; B: The endoscope was passed to the site of the obstructive tumor and a 0.035 inch teflonated guide wire was passed across the stricture under endoscopic and fluoroscopic guidance; C: A catheter was subsequently passed over the guidewire; D: A colonic self-expanding metal stent (SEMS) was used to decompress the colon. The stent was placed so as to extend at least 2 cm on each end beyond the tumor margin. After the stent was deployed, the position was assessed by endoscopic and fluoroscopic visualization.
