Dead on as usual.
IRL you can get impaled and survive if it misses everything vital. However, the heat transfer from the blade might cause some collateral damage. We need one of our resident doctors on this.
OK, if you insist.
Being impaled anywhere through the torso by a high energy weapon should be fatal, although perhaps not immediately. It depends what was hit. A few high points:
ABDOMEN:
If you hit the inferior vena cava or aorta, although the lightsaber MIGHT be able to cauterize these two large blood pipes (but when they bleed, you can HEAR the bleeding), you would still have cut off the circulatory route throughout your abdomen and lower extremities. While you might not "bleed to death" it would be akin to kinking a garden hose... no throughput.
Your small intestine is arranged all over the place in your abdomen, while in general the colon runs right side up, across the upper middle, and down the left side, towards the pelvis/rectum. Your stomach is upper/middle. A saber passing through your "gut" is going to hit some part of the GI tract and spill GI and fecal contents into your abdominal cavity. Sepsis can take a while to set-up, but if not quickly treated, you die.
PELVIS:
Your ilac and femoral vessels carry the blood on its circuit through your legs. You are more likely to survive a saber injury here IF the vessels are cauterized, but you may lose the limb if not urgently repaired. Part of you intestines also sits in your pelvis, so again... more likely to also have a GI tract injury as well.
CHEST/THORAX:
Your heart is midline and to the left. Stab it with a saber... you don't live. Impale it clean through with a metal pipe (a la John Carter) you STILL shouldn't live more than a few fleeting moments... this it not a Temple of Doom scenario, kids. Impaling either lung will cause it to collapse, and can lead to a tension pneumothorax. People HAVE regularly survived one collapsed lung, though.
Upper chest: you can hit the trachea, innominate artery, aortic arch and/or external carotid arteries at the origin. Bad news.
...and we haven't even talked about all of the nerve and bone injuries that can come from the saber stab.
