They try to get back or get help. Mostly out of panic. In the original version, not the bloody SE, I always got the impression the lair was full of wampas... like a nest... because of the multiple howls in the cave (maybe it is just me). Luke hadn't received a whole lot of training on his lightsaber by this point (good against remotes is one thing... good against living?) so maybe his best option was to just get the heck out of dodge.
