Covered, expandable esophageal metallic stent tubes: experiences in 119 patients.

Abstract

Treatment with placement of a covered expandable stent tube is effective in most patients with dysphagia due to malignant esophogastric strictures and is less effective in patients with benign strictures.

Palliative treatment of obstructing esophageal cancer with nitinol stents: value, safety, and long-term results.

“…Aspiration remains a problem even after successful stent placement because of abnormal penistalsis of the esophageal wall due to tumor infiltration and stent placement [24]. Furthermore, 5-1 5% of patients with esophageal cancer will develop esophagotracheal fistulas with subsequent risk of aspiration [3,20,24].…”

“…Aspiration remains a problem even after successful stent placement because of abnormal penistalsis of the esophageal wall due to tumor infiltration and stent placement [24]. Furthermore, 5-1 5% of patients with esophageal cancer will develop esophagotracheal fistulas with subsequent risk of aspiration [3,20,24]. We had no cases of aspiration during probing of reported on tumor ingrowth in two patients after 6 months, and N#{228}gele et al [28] used these stents in 10 patients and reported tumor ingrowth in three patients after a mean of 9 months.…”

Self-expandable covered metallic esophageal stent impregnated with beta-emitting radionuclide: an experimental study in canine esophagus

“…By employing self-expandable esophageal stents, we can expect the palliative relief of dysphagia resulting from stricture or obstruction of the esophagus (19,20). Presently, there exist the two following types of self-expandable stents: (a) covered and (b) uncovered.…”

“…Presently, there exist the two following types of self-expandable stents: (a) covered and (b) uncovered. A covered metallic stent can be used effectively in patients who have developed malignant dysphagia associated with perforation or fistula formation (20,21). Although the covered type is preferred for the prevention of tumor overgrowth, which occurs in 5%-10% of patients (19), it is so much less flexible that it shows a greater tendency toward migration than the uncovered stent (20 -22).…”

“…For covering metallic stents, silicone, polyethylene, and polyurethane have been used. Silicone-covered stents are limited in use, because of disruption of the membrane during and after stent placement (20,23). Saxon et al used a polyethylene-covered Z-stent in 35 patients and reported that it is a relatively safe and effective means of long-term palliation in patients with malignant esophageal stricture and esophagorespiratory fistula (14).…”
