What this trial studies

This observational protocol follows transgender women aged 19–99 who undergo robotic tubularized augmented peritoneal cap (TAPCap) vaginoplasty in which Kerecis fish-skin xenograft is used to line the mid-vaginal canal as part of routine surgical care. Surgeons will perform the TAPCap technique with Kerecis during planned primary vaginoplasty and collect perioperative data and biopsy samples. The study excludes revision cases, zero-depth vaginoplasty, patients requiring other off-the-shelf grafts, and those with allergies to fish products or local anesthetic. Outcomes will emphasize surgical feasibility, wound healing and lining integrity, and short-term complications at a single center in Cleveland, Ohio.

Who should consider this trial

Good fit: Transgender women aged 19–99 planning primary robotic TAPCap vaginoplasty at University Hospitals Cleveland who are not seeking revision surgery and who have no fish or local anesthetic allergy.

Not a fit: Patients needing revision vaginoplasty, zero-depth procedures, those requiring grafts other than Kerecis, or anyone allergic to fish products or the local anesthetic are unlikely to receive benefit from this protocol.

Why it matters

Potential benefit: If successful, this approach could provide a durable, skin-sparing vaginal lining that reduces donor-site morbidity and improves healing and cosmetic outcomes.

How similar studies have performed: Fish-skin grafts such as Kerecis have shown positive results in wound healing and some soft-tissue reconstruction settings, but use specifically for lining in vaginoplasty is novel and has limited published outcome data.
