Occasionally people don't need a stent, but the majority do. 2/3 of the time stents take care of the problem without additional complications (stent stays in for 6-8 weeks, comes out, and recovery is non-eventful). The other 1/3 of the time is when additional procedures are needed (more time in a stent, the stent doesn't stay in place, etc.)

You might want to ask what kind of stent they want to use. The self-expandable, covered stents seem to be pretty good... if they expand to fit the sleeve, they are less likely to migrate.

Do your research, ask lots of questions, and be comfortable with the knowledge and skill of your surgeon. Second opinions are valuable (it might be hard finding someone to take on a complication-case though.. doesn't hurt to ask!)

Good luck!
