I think there was a "bodily functions" thread elsewhere with a few lists, etc.
I do recall The Cook, The Thief... beginning with someone beaten by gangsters and force-fed dog excrement (actually, chocolate mousse)
The trick with watching scenes like that is just to know what's actually being used. (And, reportedly, the mixture of orange-marmalade & chocolate used in 'Salo' was actually quite delicious. I've seriously thought of preparing such a desert as a joke-gift next time I'm invited to a 'pot luck' type dinner
Bertolucci does seem to have a penchant for depicting such things in his movies. I'll advise* you to stay away from his "Novecento" which involves the peasants pelting Donald Sutherland with horse-manure, running out manure, then (in a surprisingly graphic close-up) massaging the horse's anus to produce some-more.
*That is, of course, unless you happen to have a particular dislike of Donald Sutherland.
I've read it's a particularly prominent theme in medieval Italy (especially in depictions of Hell; just look at Dante) Which would account for it being so unusually common in Italian films (and films by Italian directors)
