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

Abstract

BACKGROUND:

Data are limited on use of expandable metal stents for treatment of malignant gastric outlet obstruction. Accordingly, we report our experience using these stents to palliate malignant obstructions of the gastric outlet, duodenum, and proximal jejunum.

METHODS:

Eight patients with malignant strictures causing gastric obstruction underwent endoscopy with fluoroscopic guidance to delineate tumor borders and length followed by expandable metallic prosthesis placement (Wallstent, Z-Stent, Ultraflex, and Endocoil).

RESULTS:

Symptoms were relieved in seven patients, five of whom had previous surgeries (Whipple, Billroth II, esophagojejunostomy, and gastrojejunostomy) for malignancy. One patient underwent surgical resection of a presumed malignant stricture containing a previously placed Wallstent after a 45-pound weight gain.

CONCLUSIONS:

Expandable metallic prostheses placed in patients with malignant obstruction of the gastric outlet, duodenum, or proximal jejunum, before or after surgery, effectively palliate obstructive symptoms and may also serve to improve nutrition.
