Abstract
Self-expanding metal stenting is an established treatment modality in the management of esophageal growth and stricture. Reactive tissue ingrowth at the uncovered portion of the self-expanding metal stent (SEMS) anchors it in position, preventing its migration. When removal of such an embedded SEMS is clinically indicated, the procedure of endoscopic retrieval is fraught with serious complications. Temporary deployment of a larger fully covered “rescue” SEMS within the embedded SEMS has been reported to be useful in the extraction of the embedded SEMS. When the regression of embedding tissue, is only partially achieved by such “rescue” fully covered SEMS, further extraction of the embedded SEMS can prove to be technically challenging. Here we report two cases where a novel technique, namely the “double-step invagination technique,” was useful in retrieving such embedded esophageal SEMS.
