Sarah, you are looking quite pretty girl!
I found studies before that compared ileal (small intestine) to peritoneal when used for Mullerian agenesis and CAIS and upper grade PAIS patients. Both performed as expected but the study showed significantly lower blood loss and complication risk with peritoneal. Surgical times were also much shorter. Some later studies following patients of peritoneal vaginoplasty showed that the peritoneal tissues become almost indistinguishable from natal vaginal lining tissues after 6 month to a year. This is because the outer layers of the peritoneal tissues have epidural like cells for the membrane but continue to allow the inner cells secretions through. The secretions are pH similar to natal vaginal secretions as well.
The worst case I found in one study, the patient did not do any post surgical dialation. Only a cotton swab could be used to check depth due to stenosis (shrinkage of diameter). Depth was unaffected.
Dr. Gallagher said she has been working with the laproscopic surgeons to be able to offer this in Indianapolis soon. My insurance won't cover it so I never heard any more info after that. The University hospital there requires some insurance coverage to even schedule you. They simply won't do self pay.
There are doctors who do the procedure for women with MKRS in the US. Dr's Milkos and Moore do it and say it takes 1-1.5 hours but they do not do genital reconstruction.
Dr. Whitehead, who now runs the Reed Center in FL, has done it before when he worked in the hospital setting, but the Reed Center is not equipped for it. (he doesn't own his own laproscopic equipment)
Dr. Bluebond-Langer has done a shorter version for revision of past inversion inversion type vaginoplasty.
One of the SRS doctors in Serbia recently did similar for revision purposes.
The SRS surgeons in Mumbia have done a pilot group of 2 or 3 transwomen with full SRS.
The PPV is a type of Modified Davydov Method.
