Malignant Gastric and Duodenal Stenosis: Palliation by Peroral Implantation of a Self-Expanding Metallic Stent

Abstract

Implantation of stents resulted in palliative relief of malignant antrum-pylorus-duodenal obstructions.

Self-expandable metallic stents for palliation of patients with malignant gastric outlet obstruction caused by stomach cancer

“…Tumor ingrowth occurred in 14 (26.4%) patients at a mean of 78.4 d in our study. Overall recurrent stenosis rates of 8%-46% at an interval of 2-21 wk (mean, 7.5 wk) have been reported in other studies [14,15,[19][20][21][22][23][24] . It is difficult to compare our results with results of other studies because other reports included patients with a variety of cancers.…”

The use of enteral stents in colonic and gastric outlet obstruction

“…Although the experience is still early and most series are small, the rate of success for the placements of gastroduodenal stents has been very good. In some series, the technical success for stent deployment has been reported to be as high as 100% [3,15,19]. The largest series [20] reports a 93.5% success rate with the placement of 31 stents in 29 patients.…”

Gastrojejunostomy versus stent placement in patients with malignant gastric outlet obstruction: a comparison in 95 patients

“…Median survival rates in other studies ranged from 7 to 141 days after stent placement and from 70 to 249 days after GJJ [1,4,8,15,16,19,20,[25][26][27]. Previous studies have suggested that survival rates were higher after GJJ than after stent placement.…”
