Simple neovaginoplasty using spontaneous regeneration ability of labial and vestibular flap in patients with Müllerian agenesis

Clinical pilot study to evaluate the neovaginal PACIENA prosthesis® for vaginoplasty without skin grafts in women with vaginal agenesis

Background

To evaluate the feasibility and clinical outcomes of vaginoplasties using a neovaginal polylactic acid prosthesis made with 3-dimensional (3D) printing technology as an intraneovaginal mould.

Methods

This was an interventionist, prospective, and multicentre clinical pilot investigation of a sanitary product (PACIENA prosthesis®) aiming to recruit and operate on 8 patients over 6 months with a follow-up period of 6 months. Only six patients with Rokitansky syndrome and one patient with Morris syndrome (7 patients in total) were operated on in two university hospitals: “La Fe”, Valencia (H1) and “Arrixaca”, Murcia (H2). Interventions: Extensive surgical dissection of a defined space between the urethra and bladder in the front and of the rectum in the back as well as insertion of the PACIENA prosthesis® covered with Interceed® were performed. After 12 days, the prosthesis was changed to the silicone-covered version for daily application.

Results

In the 6 patients with Rokitansky syndrome (86%), the primary endpoint (satisfactory vaginal outcome in terms of appearance, function, and sensation without relevant additional morbidity) was achieved, although only 2 patients (28%) were sexually active at the end of 6 months of follow-up. The patient with Morris syndrome withdrew from the study after 1 month. Patients without bacterial colonization showed positive Schiller tests at 1 month, and subsequent biopsies showed adequate keratinization and epidermization. Epithelization and iodopositivity were delayed in the patients who developed inflammatory granulomas.

Conclusions

Good anatomical and functional results can be achieved with the PACIENA prosthesis® for vaginoplasties without skin grafts. However, adequate patient selection and education, good surgical techniques and haemostasis, postoperative support, and prevention of bacterial colonization are important.

Trial registration

This clinical study was approved by the Ethical Clinical Investigation Committee of San Juan University Hospital on September 27, 2016, to be conducted in the participating centres; it was authorized by the Spanish Agency of Medicines and Health Products (AEMPS) on April 24, 2017 (exp. no. 585/16/EC), to be carried out in that hospitals.

Novel Minimally Invasive Technique of Neovaginoplasty Using an Absorbable Adhesion Barrier

Our objective was to provide a minimally invasive neovaginoplasty technique to construct a nearly physiologic vagina to facilitate sexual functioning and appropriate vaginal length in patients with congenital vaginal agenesis. This retrospective study at a tertiary care hospital comprised 52 patients with congenital vaginal agenesis because of Mayer-Rokitansky-Küster-Hauser syndrome or androgen insensitivity syndrome presented for vaginal reconstruction. Modified McIndoe vaginoplasty was done in all patients between 2010 and 2018 using a vaginal mold created with glove, nonadherent petroleum gauze, and Interceed absorbable adhesion barrier (Ethicon, Johnson & Johnson, Somerville, NJ) that was placed in the neovagina space created between the bladder and rectum for 7 days. Operative details, complications, length and width of the neovagina, and functional outcome were evaluated. The mean operation time was 35 minutes. The mean length of the constructed neovagina was 8.4 cm × 3.4 cm at 6 weeks follow-up. Epithelialization was completed by 4 to 6 months. All patients reported satisfactory sexual activity with no pain and good mucosal sensitivity. This modified neovaginoplasty technique is easy to perform, involves painless postoperative dilatations as the cornerstone of treatment, and results in adequate secretion, allowing lubrication and acceptable physiologic results.

A case of Mayer-Rokitansky-Küster-Hauser syndrome in a low-resource tertiary hospital in Douala, Cameroon

The Mayer-Rokitansky-Küster-Hauser syndrome is the congenital absence or underdevelopment of the uterus and vagina even though the external genitalia, ovaries and ovarian function are normal. This condition is uncommon in Cameroon. A 23-year-old woman of the Fulbé tribe, a predominantly Islamic tribe of the northern part of Cameroon, complained of the absence of menstruation after age of puberty and lower abdominal pain occurring almost at the same period every month. She has been married polygamously for 10 years and has been having normal, satisfactory sexual intercourse. The sonographic and laparoscopic findings of this patient were consistent with Mayer-Rokitansky-Küster-Hauser syndrome. The patient was counseled for in vitro fertilization and surrogacy. Patients with Mayer-Rokitansky-Küster-Hauser syndrome typically present with primary amenorrhea during adolescence. With the existing medical technology in Cameroon, this condition is easily accessible in tertiary healthcare facilities. Patients with Mayer-Rokitansky-Küster-Hauser syndrome could become mothers through in vitro fertilization and surrogacy, but the cost is prohibitive in Cameroon.
