According to the Comprehensive LaTeX Symbol List (which you can find on
at http://www.ctan.org/tex-archive/info/symbols/comprehensive/ ), there
is:
\oiint in the wasysym package
\oiint in the mathabx package
\oiint in the txfonts / pxfonts package, together with \oiintclockwise
and a whole host of variants.
so
\usepackage{wasysym}
...
\oiint dx dy
should work. If you don't like these, here's a kludge I've used for
years (but it doesn't scale in size with it's argument quite the way the
above are advertised to do)
\def\ess{\textsl S}
\def\dintcl{\int\limits_{\ess}\kern-0.7em\int\kern-1.4em\bigcirc\kern.7em}
Happy integrating...
