[Clinical evaluation of covered self-expandable metallic stent for unresectable malignant stomach pyloric region and duodenal obstruction].

Abstract

We evaluated palliative treatment for unresectable malignant stomach pyloric region and the duodenal obstruction using covered self-expandable metallic stent (SEMS). Fifty-seven patients (26 stomach pyloric stenosis, 31 duodenal stenosis) were underwent palliative treatment using covered SEMS. The covered SEMS was Ultraflex stent for esophageal obstruction. The covered SEMS was successfully indwelled in the target region in 56 patients. The patients became able to ingest orally after a mean of 2 days, and 96% of the patients (54/56) became able to eat solid or semi-solid diets later. The SEMS obstruction by tumor ingrowth or hyperplasia was not occurred, so SEMS was maintenance-free. We concluded covered SEMS was useful palliative treatment because it prevented SEMS obstruction by tumor ingrowth or hyperplasia and it was maintenance-free.
