Treatment of recurrent malignant obstruction with a flexible covered metal stent after gastric surgery.
BACKGROUND
The management of gastric outlet obstruction with expandable metallic stents is difficult and frequently is associated with late complications. A new, flexible, covered metal stent has been developed, which may be suitable for treatment of patients with recurrent malignant strictures after gastric surgery.


METHODS
The stainless-steel stent is covered by a polyethylene membrane. It has a proximal funnel attached to an expanded antimigratory segment 29 mm in diameter. The flexible covering membrane connects isolated distal segments that are 20 mm in diameter. The stent is preloaded in a 6.7-mm-diameter introducer system. The structural features and the increased flexibility of this new prosthesis are intended to reduce the risk of migration and the frequency of late complications, and to broaden the range of applications.


RESULTS
This stent was used to successfully treat two patients with recurrent tortuous malignant strictures after partial or complete gastrectomy.


CONCLUSIONS
This new flexible, polyethylene-covered stent potentially is a new alternative for the palliation of patients with recurrent, inoperable gastric malignant strictures.
