Plain English summary of protocol

Background and study aims
This study aims to find out whether a new type of graft made from a patient’s own vaginal tissue can be used safely and effectively during vaginal reconstruction surgery. The graft is made in the operating theatre from a small sample of the patient’s tissue and placed into the surgical area to help healthy tissue grow during healing.

Who can participate?
Women aged 15 years and older who need surgery for vaginal stenosis, vaginal atresia or a horizontal vaginal septum may be able to take part. Women who have had similar surgery in the past using tissue taken from another part of the body may also be invited to join the control group. People cannot take part if they are receiving chemotherapy or certain immune treatments, have a known allergy to bovine products, have had radiation to the pelvis, or have specific immune conditions that affect the vagina.

What does the study involve?
Participants who need surgery will receive the new graft during their operation. A small tissue sample will be taken, prepared on a biodegradable mesh, and placed into the surgical area. After surgery, participants will be monitored for any problems and will attend check ups at about 6 months, 1 year and 2 years. These visits will include examinations, tissue samples from the graft area, and questionnaires about symptoms, sexual health and quality of life.

Participants in the control group will not receive surgery as part of this study. They will complete a set of questionnaires once. Their results will be compared with the results of the group receiving the new graft.

What are the possible benefits and risks of participating?
There may be no direct benefit. However, the new graft may help healthy vaginal tissue grow after surgery, which could improve healing and reduce complications. Risks include the usual risks linked to surgery, such as infection, bleeding or pain, as well as a small chance of allergic reactions. Participants will be monitored closely to manage any problems that arise.

Where is the study run from?
The study is run from Copenhagen University Hospital, Rigshospitalet, in Denmark.

When is the study starting and how long is it expected to run for?
The first participants are expected to join the study from 01 April 2026. The study is expected to continue until 2033.

Who is funding the study?
The study is funded by the Independent Research Fund Denmark and two grants from the Novo Nordisk Foundation.

PurposeDevice feasibility, Treatment
Scientific titleUsing the Personalized Layered Autologous Tissue Expansion graft in VAGinal reconstructive surgery and patient reported outcomes measures for comparison with previously treated patients

Study objectives The aim of the study is to evaluate the feasibility, safety, and clinical use of a new perioperative method for autologous tissue expansion in vaginal reconstructive surgery.
Ethics approval(s)

Approved 14/10/2025, De Videnskabsetiske Komiteer for Region Hovedstaden - The Research Ethics Committee for the Capital Region (Borgervænget 3, ST, Copenhagen, 2100, Denmark; +45 3866 6395; vek@regionh.dk), ref: H-25043127

Health condition(s) or problem(s) studiedVaginal atresia, vaginal stenosis and vaginal septum needing surgical intervention.
InterventionThe participants in the study will consist of two groups
1. Patients diagnosed with a vaginal stenosis, vaginal atresia or vaginal horizontal septum with an indication for surgical correction (intervention group)
Intervention: Surgical intervention will be performed withan autologous surgical graft called the Perioperative Layered Autologous Tissue Expansion (PLATE) graft. Briefly, the PLATE-graft consists of a minced biopsy of the patient’s own vaginal mucosa, spread on a biodegradable mesh and imbedded in a collagen hydrogel. The collagen hydrogel is compressed to expel its water content, and then sutured into the surgical vaginal wound to allow for tissue expansion during postoperative healing. The PLATE-graft is constructed perioperatively inside the operating theatre, next to the patient within 30 minutes.

2. Control patients who have previously undergone surgical correction for vaginal stenosis, vaginal atresia or vaginal horizontal septum using autologous donor tissue from another organ (e.g. buccal mucosa, intestine or skin) (control group).

The intervention group and the control group will both answer questionnaires related to female health after at least 1 year after vaginal reconstructive surgery
Intervention typeProcedure/Surgery
Primary outcome measure(s)
  1. Vaginal patency measured using vaginal patency, stricture evaluation, biopsies from the graft area at 6 months, 1 year and 2 years postop.
  2. Adverse events measured using clinical evaluation, pain medication at 2 weeks, 6 months, 1 year, 2 years after surgery
Key secondary outcome measure(s)
  1. Patient QoL and symptom scores before and after the surgery measured using validated questionnaires; FSFI, FSD and WHO QOL brief to the intervention group and the historic control at Intervention group: Preop, 6 months, 1 year and 2 years after surgery. Control group: 1 time point at any time period after surgery
Completion date01/01/2033
