Abstract

ABSTRACT

Clinical utilization of self-expandable metallic stent (EMS) endoprosthesis has come later for colorectal diseases than for other lesions. Recently, EMS has been used for palliative insertions for strictures caused by malignant diseases or as a ‘bridge to surgery’ for obstructive colorectal cancers, with good clinical results increasingly reported in many western countries. Its application for benign strictures has been reported, but we believe that the surgical indications require more careful analysis because of the absence of data concerning long-term prognosis. The advantage of this technique in the treatment of colorectal strictures is that it limits invasiveness, such as in palliative or temporary stoma creation, thereby improving patient quality-of-life. Therefore, we believe that EMS endoprosthesis will play a key role in this field. We are awaiting the introduction of the metallic stent for the colon and the associated kit, as well as the Japanese government's approval for reimbursement for this procedure.
