Hi all..
This is what I'm hoping for in the future, a kind of rubber type sphincter and artificial anal mucosa that replaces patients sphincter and mucosal tissue due to tears and fissures etc, I know they already make an artificial sphincter to combat fecal incontinence:

So maybe it's just a matter of time before they concentrate on other ano-rectal conditions such as fissures and hemmorhoids, replacing the whole inside of the anus would be massive (if at all possible) but the way surgical procedures are advancing, who knows?
I believe that by replacing the internal sphincter with a rubber type inflatable one (like the fecal incontinence one) and the anal mucosa with a prosthetic type would be the end of anal pain forever!
I wouldn't hesitate having that type of surgery if it meant the end of fissure and anal pain.
Here's hoping...
