Palliation of Malignant Gastric and Small Intestinal Strictures With Self-Expandable Metal Stents

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.…”

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.…”

“…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.…”

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

“…The main factors limiting the use of a gastroscope for distal duodenal stenting are the relatively short endoscope length, and shaft flexibility, which may cause looping of the scope into the stomach. The use of a colonoscope may potentially overcome these problems [6,[9][10][11].…”
