Expandable metallic prostheses for malignant obstructions of gastric outlet and proximal small bowel

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.…”

Use of a colonoscope for distal duodenal stent placement in patients with malignant obstruction

“…Remarkably, 13% (80/606) patients in this review were treated with a covered esophageal stent placed in the distal stomach/proximal jejunum. A clear drawback of uncovered stents in the duodenum is the occurrence of hyperplastic tissue or tumor growth through the mesh of the stent [15][16][17]. In the present study, we only used uncovered stents, whereas a second uncovered stent for tissue or tumor ingrowth was performed for six occluded stents in five patients.…”

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

“…In the GJJ group, re-interventions included surgical procedures for delayed gastric emptying by dilation of the anastomosis, persistent pain, or occlusion of the anastomosis by an ileostomy. Re-interventions were performed in 20/49 (41%) patients after stent placement, whereas other studies have reported lower re-intervention rates [8,[19][20][21] condition may have been selected for stent placement, as this is a less invasive treatment than GJJ. In addition, the use of different stent designs and surgical techniques may also have played a role.…”
