I Have a Scar from a Pyloric Stenosis and my Surgeon Wants to Do a Vertical Cut for Tuck, Is this Extra Risky?

A vertical scar tummy tuck is not very common but there are some occasions where it's a good choice. I hope you resubmit your question with a photograph. It is not at all unusual to see a patient for a tummytuck that has some upper abdomen scarring. I usually do a standard lower abdomen incision and pull the upper scar down with the rest of the skin.

I agree with Dr. Rosen that a vertical scar should be avoided in a tummy tuck unless there is a great deal to gain from the tradeoff.  Without a little more information it is difficult top give you specific advise or to know what your plastic surgeon is thinking.  If you object to the new scar in the upper abdomen, it is likely your PS would use a more traditional approach for you.  Make sure you communicate your concerns.
