Abstract

We prospectively analyzed the clinical outcomes of 72 patients (2,3) and we came to similar conclusions. Conceptually, covered stents present the advantage to prevent tumor ingrowth within the stent, and, being more compliant, they could facilitate pyloric motility. However, they dislodge more easily, and distal migration of the stent can lead to serious consequences (4).
