From Gamespot:
Caduceus: Surgical Operation follows a sci-fi storyline, meaning that all the illnesses and operation procedures in the game will be fictional. Atlus labels Caduceus as a "sci-fi surgery action game," suggesting that the game also has some action involved.
The game is slated for release in spring 2005 in Japan.

Stuff like this is why I'm getting a DS. I hope more and more weird stuff comes out for the system.
