Depending on what you want to do, maybe you could create a function
wich returns the value you're interested in? E.g.:

$ loop()
> {
> local x=0 i
> while read i ;do echo "x = $x"; (( x += i )); echo "new x = $x"; done

$ cat <<END | loop; x=$?

x = 0
new x = 1
x = 1
new x = 3
x = 3
new x = 6
$ echo $x
6
