Nick, I hope the surgeon is taking about a stricture (as Marie asked). Strictures are a bit like a rubber band around the tube (intestine), constricting it. Strictures can be dilated, cut, or removed completely. If you get to know what's going on in more detail, you'll be better equipped after the procedure. Even if you develop another stricture they can often be kept open enough by regular dilations, which many folks do at home.
