monad comrehension query

Hello. Is list-like monad comprehension not supported? Is there a simple & elegant way of expressing ghc-extended pattern matching using `do' notation instead of list comprehension? (I dont want to end up using the case statement). I still dont understand monads too well so i apologize if this is a silly question.
