¹Three patients initially had an AXIOS 10 mm × 10 mm placed, which was immediately upsized to 15 mm × 10 mm;

²Technical success was defined as appropriate stent placement across the stricture verified endoscopically and fluoroscopically;

³Technical success was defined as successful placement of the LAMS across the stricture;

⁴Clinical success was defined as resolution of underlying symptoms for at least 6 mo after stent placement;

⁵Short-term clinical success was defined as symptom improvement/resolution with indwelling stent;

⁶Long-term clinical success was defined as symptom improvement/resolution after stent removal. LAMS: Lumen-apposing metal stent.
