Scar tissue

How much scar tissue should one expect to get from RNY. Does it cause further complications down the line?

No way to say because everyone heals differently.  Having lap surgery GREATLY reduces scar tissue over open surgery, though because of the significantly smaller incision areas.

Scar tissue from any surgery can cause problems down the road, but not everyone (not even every person who has had many surgeries) will suffer problems from the scar tissue.  The greater the number of surgeries, the greater the risk of problems from adhesions (scar tissue that causes one surface to "stick" to another).  That is one of the reasons that some surgeons remove the gallbladder at the same time as the RNY... To limit the scar tissue and general anesthesia risk from a second surgery since 30% or so of people need their gallbladder a removed after massive weight loss.

Strictures, BTW, are an excessive amount of scar tissue that forms on the stoma (so that is a form of complication from scar tissue).
