Full-length peritoneal flap vaginoplasty: a hairless neovagina
What it is
This is a way to create a neovagina in MTF surgery using only the peritoneum, a soft, moist, stretchable membrane that lines the abdominal organs, rather than penile or scrotal skin. Because skin is not used to line the canal, there is no hair inside it. The peritoneum gives a smooth, mucosa-like surface, a natural self-lubricating effect, and a fully internal result from opening to apex. Dr. Worapon Ratanalert introduced the technique to address the hair growth, dryness and texture mismatch that can come with skin-based methods.
Who it suits
The approach is useful if you have hirsute (hairy) genital skin, had prior hair removal or surgery that left limited skin for reconstruction, prefer to avoid bowel-based vaginoplasty, or want a hairless, self-lubricating canal without extra grafts or a complex recovery. One caveat: previous abdominal surgery can make it less suitable, because internal scarring complicates the laparoscopic harvest.
How the surgery works
- Laparoscopic harvesting — through small instruments, the surgeon collects an approximately 20 x 20 cm flap of peritoneum from the abdominal wall.
- Shaping the canal — the flap is rolled into a tube and attached inside the body to form the canal from deep apex to opening.
- No skin bridge — unlike part-skin, part-peritoneum methods, this uses only peritoneal tissue, so no hair-bearing skin lines the canal.
- Secure attachment — the flap is connected to the bladder lining and pulled through to the opening, where it is anchored with labial flaps made from remaining penile skin.
How it compares to PPV
Many patients arrive familiar with penile-peritoneal vaginoplasty (PPV), which mixes skin and peritoneum and usually lines only the apex with peritoneum. The table shows the differences that matter for a hairless, uniform result.
| Feature | Full-length peritoneal flap | Traditional PPV |
|---|---|---|
| Hairless canal | Entire canal, no skin used | Lower part may contain hair-bearing skin |
| Tissue type | All peritoneum (moist, elastic, mucosa-like) | Mixed skin and peritoneum |
| Lubrication and comfort | Self-lubricating end to end | Only apex lubricated; lower half may be dry |
| Aesthetic uniformity | Single tissue type throughout | Possible texture or appearance mismatch |
| Risk of hair regrowth | Eliminated | Possible, especially in scrotal-skin areas |
| Skin grafts required | None, unless the flap is too short | Often used to bridge to the introitus |
| Ideal for | Limited or hairy genital skin | Adequate, hairless skin available |
What the study showed
The case series followed 10 transgender women with an average age of 27.5. Most kept the same vaginal depth, around 5 to 6 inches, at the 3-month follow-up. The canal appeared pink, elastic, hairless and slightly moist, resembling natural vaginal tissue. One patient developed narrowing after stopping regular dilation, and minor urinary symptoms were noted but did not cause major problems.
Recovery and aftercare
Patients use custom vaginal dilators twice daily for one year to maintain depth and width. Intercourse is allowed after 3 months. Some mild secretions are expected at first but did not require ongoing pad use, and lubricant is recommended during sex.
Risks to weigh
The early results were positive, but there are things to watch: abdominal adhesions (scar tissue), possible nerve injury (none occurred in this study), and the rare case where the flap is not long enough and needs a small skin graft. If this method does not succeed, bowel (colon) vaginoplasty remains an option for revision. Because it is fully laparoscopic, it avoids large incisions and intestinal surgery, and it lines the whole canal with peritoneum rather than only the deepest part.

Frequently asked questions
What is full-length peritoneal flap vaginoplasty?
It creates the entire vaginal canal using only peritoneum, a smooth abdominal lining, instead of skin or bowel tissue, for a completely hairless, moist, natural-feeling neovagina. Dr. Worapon Ratanalert introduced the technique at Yanhee.
How is it different from PPV?
PPV combines skin and peritoneum, usually with peritoneum only at the apex. The full-length technique uses peritoneum from opening to apex, so the whole canal is hairless and mucosa-like, with no skin or bowel tissue and no risk of internal hair.
Who is a good candidate?
Trans women with limited or hairy genital skin, those who had prior hair removal, anyone wanting a hairless self-lubricating canal, and those who prefer laparoscopic surgery over bowel methods. Prior abdominal surgery can make it less suitable.
Does it preserve sensation?
Yes. The procedure is designed to maintain nerve structures for a sensate neovagina. No nerve injuries occurred in the published case series.
What is the aftercare?
Custom dilators twice daily for one year to maintain depth and width, intercourse after 3 months, mild secretions expected at first, and lubricant recommended during sex.
