The best way is to learn from the mistake and build a portal near the area you intend to explore before you start exploring that area so that you don't have far to go to recover your gear if you get killed. You can just put your old troll armor set on and sneak up to your corpse to recover it.

Without using any of the above cheese methods or asking for help you can sneak as close as possible and then build a portal so that if you die you don't have far to go. Then you can get the attention of all the stuff that is in your way and sprint away at a 90 degree angle to lead them away until they kill you again. Portal back and repeat until you have moved all the stuff guarding your path out of the way and once that is done portal back and sneak to your corpse.
