Research Hari Kiri or Sepuku (check the spelling on both) - Japanese ritual suicide - for more information on the actual cause of death and how long it takes with disembowelment.
As you describe things in your second post (surgical incision so no arteries are nicked and then when the victim shifts the intestines will come out possibly severing their own arteries as the organs release themselves), I imagine it would take your victim a very, very long time to die.
If the initial cut is only through the abdominal wall, only capillaries and minor arteries and veins will be cut. Then when your victim tries to stand or rolls over onto his side, the intestines would spill out through the cut.
A deeper slash (like with a sword), will kill quicker because more arteries and veins (including those feeding the intestines) will be cut open. The blood supply to the intestines is huge. A deep slash will also cut open the intestines, dumping all sorts of nasty fecal matter into the abdominal cavity (the victim may survive the disemboweling only to die of peritonitis).
I'm not familiar enough with Dermabond to say.
If you want your victim to have a chance to live, have him or her lay on their back with their hands pressed over the cut to prevent the intestines from getting out.
Hope this helps.
