Well, depending on why you're returning to the surface there are a few things...
If it's for excessive loot, you can use a piggy bank or a safe (later in the game) as a mid-dungeon storage. The space a table and piggy bank takes up in your inventory is well worth it.
If it's due to logging out of the game, short of building a house and saving there, I don't think there's any way of doing it. You'll need to replace the back wall in a lot of cases which can make this impossible.
If it's a temporary "because" you could use a portal gun. That, however, you can't get until you're pretty much done with the game... So... you did say "ever".
If it's from death, you're pretty much out of luck if you're playing alone. If with others, though, you can use wormhole potions to teleport to allies (which would work for the random leaving and excessive loot reasons as well)... assuming the ally stays alive.
