Novel use of lumen-apposing metal stent for recanalization of complete stenosis of colo-colonic anastomosis.

Abstract

Combined antegrade-retrograde dilation [1] is an established technique that has been adapted for benign colonic obstruction [2] [3] but requires use of accessory devices and predilation followed by deployment of self-expanding metal stents [2] [3]. Rendezvous sigmoidorectal reanastomosis using a lumen-apposing metal stent (LAMS) has also been described with endosonographic (EUS) guidance [4]. We hereby report a recanalization of complete stenosis of a colo-colonic anastomosis without EUS guidance.
