Here's a little macro I came up with that might help somewhat. It searches through a document and when it finds the text string *DELETE* it deletes that page. You could change the search text to whatever you wanted but you need to make sure it will be something that would NOT appear on any page you wanted to keep.
Basically, you would go through your doc and put the search text on any page you want deleted then run the macro. Afterwards you will need to save the doc so no pages will actually be deleted from the doc until you save it. I'd advise saving it under a different name until you're sure it worked correctly.
I haven't tested it extensively so make sure you have a backup of your doc before you run it.
Dim strSearch As String
Dim rgeStart As Range
Set rgeStart = Selection.Range
strSearch = "*DELETE*"
.Text = strSearch
Do While .Execute
Application.Browser.Target = wdBrowsePage
