I don’t have problems with mucus. My issues were my throat kept closing and would require an EGD a couple times a month to get stretched back out. The stents worked but I got tired of them and looked for a different solution to the problem. I met someone from a cancer support group I belong to who was doing self dilation. It sounded like something I could try so I teed it up with my GI doctor who was very familiar with it and told me it was worth trying, so I did and it has worked wonderfully. I am not sure your husband would be a candidate because of the mucus issues but it definitely would be worth your time discussing with his doctors.
