I promised to give an update. Here we go.
The Russians first started using peritoneum to form a neo vagina in patients with Mayer-Rokistansky-Kustner-Houser syndrome. In this syndrome a cis woman does not fully develop her sexual organs and has several other anomalies involving kidneys and bladder. Notably, women with this syndrome do not develop a vagina. In 1969 an article showed up in Russian literature using the peritoneum to form the vagina but they utilized a laparotomy technique (fully open abdomen) that left significant scaring. They did note that the women were able to engage in sex and self lubricated.
In 1983 the first laproscopic procedure was used which resulted in significantly reduce surgical time and fewer complications as well as a quicker recovery.
Several modifications of technique were developed in the early part of the 2000's.
In 2014 an Indian team modified the technique further with what they are calling the pull through technique. In this there are three small abdominal incisions that leave little scaring. The vaginal cavity is opened up and the peritoneum is pulled through and sutured in place. This reduces the possibility of prolapse. Dilation is twice a day for the first three months and then not needed. Of interest is that the peritoneal cells modify over a period of 6-8 months and become vaginal epithelial cells that are not differentiated in any way from a normal vagina. There is high sexual satisfaction and normal lubrication.
I would note that all that i have cited so far is for cis women that have no vagina. Dr Bowers and Dr Ting are working with this technique for trans women. Without doing significant research on this tonight I would note that since trans women do not have natural vulva, labia, clitoris it is still necessary to restructure existing male anatomy.
I still find this a very interesting development.
the articles that I used in particular are as follows:
