Anatomic and Functional Outcomes of Paramesonephric Remnant-Supported Laparoscopic Double-Layer Peritoneal Pull-Down Vaginoplasty Technique in Patients with Mayer-Rokitansky-Küster-Hauser Syndrome: Uncu Modification

Unification and orificing of two functional noncommunicating uterine horns through the created neovagina using peritoneum

OBJECTIVE

To demonstrate the surgical approach for Müllerian agenesis with bilateral uterine remnants containing functional endometrium.

DESIGN

Stepwise demonstration of the technique with narrated video footage.

SETTING

Reproductive surgery unit of a tertiary university hospital.

PATIENT

An 18-year-old adolescent was admitted to a tertiary university hospital with complaints of primary amenorrhea and cyclic pelvic pain. Physical examination and magnetic resonance imaging scans suggested a complex Müllerian abnormality. The patient had uterine remnants with bilateral functional endometrium and cervicovaginal agenesis.

INTERVENTION

An operation was planned to reconstruct her anatomy by providing a neovagina and anastomosing the uterine remnants. Gonadotropin-releasing hormone analogs were prescribed to suppress her menstruation until the procedure. The operation was performed in the third month after the initial diagnosis. A laparoscopy was conducted, revealing approximately 5 × 6-cm bilateral uterine horns with healthy adnexa. As the first step, a neovagina was created using a modified peritoneal pull-down technique, a standard approach in our clinic. A vaginal incision was made, and a blind vaginal dissection was performed to reach the peritoneum vaginally. Subsequently, an acrylic vaginal mold was inserted. The vaginal orifice was laparoscopically incised using ultrasonic energy with guidance from the inserted vaginal acrylic mold. The orifice was gradually dilated with larger molds. The entire pelvic peritoneum was dissected circularly, and the distal part of the dissected peritoneum was pulled down using four 2.0 Vicryl sutures at 0°, 90°, 180°, and 270° from the opened vaginal orifice. The uterine cavities of both remnants were incised, and two separate Foley catheters were placed in both cavities. A mold with a hole was used to insert the catheters through the vagina. Both catheters were secured in the cavities with Prolene sutures pulled up from the anterior abdominal wall. The next step involved uterine anastomosis. The uterine remnants were unified through continuous suturing, resulting in the formation of a normally shaped uterus. In the final step, the created uterus and neovagina were anastomosed. The patient received instructions on how to perform mold exercises and follow-up care.

MAIN OUTCOME MEASURE

Description of laparoscopic management of a rare Müllerian abnormality.

RESULTS

The postoperative magnetic resonance imaging scan at 1 month revealed healed unified uterine cavities and vagina. The patient experienced spontaneous menstruation in the second month after surgery and now maintains regular menses with an approximately 9-10 cm functional vagina. Within 3 months after surgery, the visual analogue scale scores for chronic pelvic pain and dysmenorrhea decreased from 9 to 2-3.

CONCLUSIONS

Müllerian abnormalities are exceptionally rare, and their spectrum is broad, making it challenging to identify an exact surgical method to restore functional anatomy. Therefore, a customized surgical approach should be designed for each patient on the basis of their unique condition.

Laparoscopic Davydov vs. laparoscopic Vecchietti neovaginoplasty in women with Mayer-Rokitansky-Küster-Hauser syndrome; a systematic review and meta-analysis

OBJECTIVE

To summarize the available evidence on the laparoscopic Davydov and Vecchietti methods to create a neovagina and to compare these techniques with a focus on neovaginal length, sexual function, operative time, and complications.

DESIGN

A systematic electronic search up to August 2022 using PubMed and Embase is performed.

SETTING

Not applicable.

PATIENTS

Women with Mayer-Rokistansky-Küster-Hauser syndrome.

INTERVENTIONS

All published clinical studies concerning the laparoscopic Davydov and laparoscopic Vecchietti procedures as a surgical technique to create a neovagina in women with Mayer-Rokistansky-Küster-Hauser syndrome were obtained. The guidelines for the preferred reporting items for systematic reviews and meta-analysis were followed. The following data were extracted: operative time, hospital stay, major early complications (within 3 months postsurgery), dilation therapy, neovaginal length, vaginal discharge, vaginal stenosis, time to sexual activity, sexual satisfaction, penetrative sexual activity, dyspareunia, score on the Female Sexual Function Index (FSFI), and duration of follow-up. The Newcastle Ottawa Scale was used to assess the quality of articles.

MAIN OUTCOME MEASURES

Neovaginal length, FSFI scores, operative time, and complications.

RESULTS

A total of 1,163 articles were identified, of which 31 studies were included in this systematic review. Of these, 12 studies (380 patients) are related to the Davydov method, 17 studies (804 patients) to the Vecchietti method, and 2 articles concern both. There is clinical heterogeneity and variety in the quality of the studies. Nineteen studies were included in the meta-analyses. The mean neovaginal length 12 months after the Davydov method is 8.3 cm (95% confidence interval [CI] 8.1-8.6), vs. 8.7 cm (95% CI 7.2-10.3) after the Vecchietti method. The mean FSFI score after the Davydov method is 28.9 (95% CI 26.8-31.1), compared with 27.5 (95% CI 25.0-30.1) after the Vecchietti method. The operative time of the Davydov method is 126 minutes (95% CI 109-143), compared with 40 minutes (95% CI 35-45) of the Vecchietti method.

CONCLUSIONS

The operations yield comparable neovaginal length, sexual function, and complication rates. The mean FSFI scores indicate no sexual dysfunction in either group. The operative time of the Davydov method is significantly longer. There is no superiority shown for one of the surgical techniques in functional terms.

Long term sexual outcomes of Mayer Rokitansky Küster Hauser Syndrome patients after Uncu-modified Davydov procedure

Background

Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome has an incidence of 1 in 4000. The absence of the vagina and uterus results in sexual dysfunction and infertility. The first-line treatment is vaginal dilatation. There exists a number of second-line surgical options including the Uncu-modified Davydov procedure.

Objective

To determine the complication rate, anatomical outcomes, and long-term sexual outcomes of MRKH syndrome patients after Uncu-modified Davydov procedure.

Materials and Methods

Patients with MRKH syndrome who underwent paramesonephric remnant-supported laparoscopic double-layer peritoneal pull-down vaginoplasty (aka Uncu-modified Davydov procedure) between January 2008 and December 2021. The procedure involves laparoscopic circular dissection of the pelvic peritoneum followed by pulling down, through the opened vaginal orifice, and suturing the vaginal cuff with the support of uterine remnants. The long-term complication rate, anatomical outcomes, and sexual function outcomes (as measured by Female Sexual Function Index (FSFI)) were ascertained.

Main outcome measures

Main Outcome Measures: The long-term complication rate, anatomical outcomes and FSFI survey results.

Results

A total of 50 patients with MRKH syndrome underwent the Uncu-modified Davydov procedure between Jan 2008- Dec 2021. There were four perioperative complications: three bladder injuries (6%) and one rectal serosa injury (2%). Four long-term postoperative complications were identified: one vesicovaginal fistula (2%), one recto-vaginal fistula (2%), and two vaginal stenoses (4%). All patients were physically examined at least one year after surgery. The mean vaginal length was 8.4 + 1.9 cm. The mean FSFI score was 31.5 + 3.9 (minimum score of 24, maximum score of 36).

Conclusion

Conclusion: The Uncu-modified Davydov procedure has been demonstrated to be a safe and effective treatment option with high female sexual function index scores for patients with MRKH syndrome.

What is new?

The long-term complication rate, anatomical and sexual outcomes of Uncu-modified laparoscopic peritoneal pull-down vaginoplasty were reported in this study. The results indicated that the surgical approach could be used in selective MRKH patients who failed first-line self-dilatation therapy.

Comparing Anatomical and Functional Outcomes of Two Neovaginoplasty Techniques for Mayer-Rokitansky-Küster-Hauser Syndrome: A Ten-Year Retrospective Study with Swine Small Intestinal Submucosa and Homologous Skin Grafts

Objective

This study aimed to compare the anatomical and functional outcomes of the modified McIndoe vaginoplasty for Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome using swine small intestinal submucosa (SIS) graft or homologous skin grafts.

Methods

A total of 115 patients with MRKHs who underwent neovaginoplasty between January 2012 and December 2021 were included in the study. Among them, 84 patients received vaginal reconstruction with SIS graft, whereas 31 neovaginoplasty underwent a skin graft procedure. The length and width of the neovagina were measured, and sexual satisfaction was evaluated using the Female Sexual Function Index (FSFI). The operation details, cost, and complications were also assessed.

Results

The SIS graft group had a significantly shorter mean operation time (61.13±7.17min) and less bleeding during the operation (38.57±9.46mL) compared to the skin graft group (92.1±9.47min and 55.81±8.28mL, respectively). The mean length and width of the neovagina in the SIS group were comparable to the skin graft group at 6 months follow-up (7.73±0.57 cm versus 7.6±0.62cm, P=0.32). The SIS group had a higher total FSFI index than the skin graft group (27.44±1.58 versus 25.33±2.16, P=0.001).

Conclusion

The modified McIndoe neovaginoplasty using SIS graft is a safe and effective alternative to homologous skin grafts. It results in comparable anatomical outcomes and superior sexual and functional outcomes. Overall, these results suggest that the modified McIndoe neovaginoplasty using SIS graft is preferred for MRKH patients who require vaginal reconstruction.

Laparoscopic Vaginoplasty Procedure Using a Modified Peritoneal Pull-Down Technique with Uterine Strand Incision in Patients with Mayer-Rokitansky-Küster-Hauser Syndrome: Kisu Modification

Various vaginoplasty procedures have been developed for patients with Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome. Here, we describe a novel laparoscopic vaginoplasty procedure, known as the Kisu modification, using a pull-down technique of the peritoneal flaps with additional structural support to the neovaginal apex using the incised uterine strand in patients with MRKH syndrome. Ten patients with MRKH syndrome (mean age at surgery: 23.9 ± 6.5 years, mean postoperative follow-up period: 17.3 ± 3.7 months) underwent construction of a neovagina via laparoscopic vaginoplasty. All surgeries were performed successfully without complications. The mean neovaginal length at discharge was 10.3 ± 0.5 cm. Anatomical success was achieved in all patients, as two fingers were easily introduced, the neovagina was epithelialized, and the mean neovaginal length was 10.1 ± 1.0 cm 1 year postoperatively. No obliteration, granulation tissue formation at the neovaginal apex, or neovaginal prolapse was recorded. Five of the 10 patients attempted sexual intercourse and all five patients were satisfied with the sexual activity, indicating functional success. Although the number of cases in this case series is few, our favorable experience suggests that the Kisu modification of laparoscopic vaginoplasty procedure is an effective, feasible, and safe approach for neovaginal creation in patients with MRKH syndrome.

New Laparoscopic Vaginoplasty Procedure With a Modified Peritoneal Pull-Down Technique in Four Patients With Mayer-Rokitansky-Küster-Hauser Syndrome

BACKGROUND

Various vaginal reconstructive procedures have been described for patients with Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome. We describe the success of a novel laparoscopic vaginoplasty procedure using an anteroposterior peritoneal pull-down technique.

CASE

Four patients with MRKH syndrome underwent a modified laparoscopic Davydov procedure using an anteroposterior peritoneal pull-down technique with a transverse laparoscopic incision below the strand. Anatomical success was achieved in all patients, allowing easy introduction of 2 fingers, an epithelialized neovagina, and a mean length of 8.0 cm (range 7.0-9.0cm). All 3 patients who attempted sexual intercourse were successful, and neovagina size was adequately maintained at the long-term follow-up in the remaining patient.

SUMMARY AND CONCLUSION

This novel procedure presents as a feasible and an effective approach for vaginal reconstruction in patients with MRKH syndrome.

Laparoscopic vaginal bead pull-through vaginoplasty technique using dental prosthesis material

Objective:

Many reconstructive surgical procedures have been described for vaginal agenesis. Almost all are surgically challenging, multistage, time-consuming or leave permanent scars on the abdomen or skin removal areas. The aim of this study was to introduce a simple and cheaper approach for laparoscopic vaginal bead-pull through.

Materials and Methods:

In this retrospective study, we report a total of six patients with congenital absence of vagina [Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome] who were treated with a laparoscopic vaginal bead pull-through technique between 2018 till 2019 with a dental prosthesis material.

Results:

Six patients with MRKH syndrome were treated with a laparoscopic vaginal bead pull-through technique. None of the women had any previous treatment. The mean age at the time of surgery was 18.7±3.1 years and mean body mass index was 25 (range, 19-38) kg/m². None of the patients had any additional malformations. In all patients, normal external genitalia and complete vaginal agenesis were observed during examination. The mean duration of surgery was 72 (range, 55-95) minutes. All patients were discharged on the 3^rd postoperative day. No intraoperative complications were encountered. All patients had their urinary catheters removed within 12 hours after surgery. The mean vaginal length at discharge was 10 (range, 8-13) cm and all patients had adequate vaginal diameter, allowing introduction of three fingers easily. At the 12^th postoperative month, the mean vaginal length was 9.2±1.6 cm. All patients had complete epithelization. All the women were sexually active one year after surgery.

Conclusion:

The laparoscopic vaginal bead pull-through technique using dental prosthesis material can provide satisfactory results with shorter surgical time and lower cost.
