You missed the passage to the rest of the instance. Maybe someone else remembers how to get to the section you missed that is not obvious. Have you tried using the instance map to identify the places you have not been? The spots where the walls do not exist? Or where there is a gray spot indicating that you haven't been there yet?
The instance is designed to be a challenge to get thru with the ups and downs. There are several instances in Moria that are designed for customers that like to explore. Quest objectives are placed around the edges of the open spaces and carefully made non obvious by the way the terrain is built.
