Self - expanding Wallstent for Palliative Treatment of Malignant Esophageal Stenosis / 대한소화기내시경학회지

ABSTRACT

The main objective of palliative treatment of malignant esophageal stenosis is rapid restoration of passage of fluid and solids. Endoscopic intubation with plastic endoprosthesis may lead to prompt relief of dysphagia and is a effective procedure for the palliative treatment of malignant esophageal stenosis. However, the insertion procedure, which necessitates prior dilatation, is traumatic and associated with considerable risk for perforation and bleeding. Tumor overgrowth, stent migration and stent blockage are frequent complications. Recently, self expanding metal stents woven in the form of tubular mesh made from surgical grade stainless steel alloy filaments(Wallstent), have been developed to offer possible advatage over conventional plastic tubes. The small diameter of introducer system carrying the compressed stent(18Fr) allows a relatively easy insertion procedure that dose not require prior dilatation. This stent is pliable. self-expanding and flexible in the longitudinal axis. We experienced a case of a 74-year-old male with malignant esophageal stenosis in whom self-expanding Wallstent was implanted with successful oral nutrition and much improvement of dysphagia.
