Clinical outcome of the use of enteral stents for palliation of patients with malignant upper GI obstruction

The use of enteral stents in colonic and gastric outlet obstruction

“…This series also achieved a good clinical outcome (defined as the ability to eat or retain feeds without vomiting) in 80.6% of patients. The reported range of good clinical outcome is 80-100% [6,8,14,15,20]. The result of our series are in agreement with the above-stated numbers, with a technical success rate of 100% and initial clinical improvement of obstructive symptoms of 100%.…”

“…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. This series also achieved a good clinical outcome (defined as the ability to eat or retain feeds without vomiting) in 80.6% of patients.…”

“…Tumor overgrowth is more common than ingrowth [16]. The number of obstructions reported has been <2% in series of 12-29 patients [5,6,20]. There have been no reports of death directly related to stent placement [16].…”

Role of self-expandable metal stents in the palliation of malignant duodenal obstruction

“…In a recently published study, Yim et al [58] retrospectively compared a group of patients who had endoscopic enteral stenting with a similar cohort of patients with pancreatic cancer who had surgical gastrojejunostomy. Their study found that endoscopic enteral stenting was much less expensive then surgery.…”

Pankreaskarzinom

“…Die Implantation von Duodenalstents ist eine zunehmend angewandte Alternative und gelingt technisch in nahezu allen Fällen. Allerdings zwingen Komplikationen, Tumoreinbruch oder -überwuchs zu einer Revision in bis zu 50% der Fälle [15,16]. Eine prospektiv-randomisierte Studie zum Vergleich Gastroenterostomie vs. Duodenalstent wird zurzeit deutschlandweit durchgeführt.…”
