You can use arbritrary latex environments inside a latex block with these 
header arguments:

:  :results raw :wrap latex :post postenv("env-name-goes-here")

If you define a wrapper for the results like this:

#+NAME: postenv
#+BEGIN_SRC emacs-lisp :var env="myverb"  :exports none
(format "\\begin{%s}\n%s\\end{%s}" env *this* env)
#+END_SRC

Then calling

#+header: :results raw :wrap latex :post postenv("myverbatim")
#+BEGIN_SRC sh :exports results
echo "Hello_world"
#+END_SRC

gives:

,----
| \begin{myverbatim}
| Hello_world
| \end{myverbatim}
`----

under latex export.

The `:results raw' is needed particularly for multiline results.

See the manual for each of those header args for more info.

You can also do this using :prologue and :epilogue, but I think :post is a 
bit neater.
