Colonic stent placement for sigmoid colon stricture


Self-expanding metal stents are a treatment option for colonic strictures, especially in debilitated patients for whom the risks of surgery are great. The stents are usually placed by gastroenterologists using an endoscope. Endoscopic imaging alone or with fluoroscopic imaging can be used. The fluoroscopic imaging helps with an overall assessment of stent placement. Success rates are >90 % for decompression of the colon.

This patient’s stricture was the result of prior inflammatory disease.
