Laparoscopic rectosigmoid colpopoiesis: does it benefit our transsexual patients?

Outcome measures reported following feminizing genital gender affirmation surgery for transgender women and gender diverse individuals: A systematic review

Background

Feminizing genital gender affirmation surgery (fgGAS) may be an essential adjunct in the care of some transgender women and gender diverse individuals with gender incongruence. However, the comparison of different techniques of fgGAS may be confounded by variable outcome reporting and the use of inconsistent outcomes in the literature. This systematic review provides the most in-depth examination of fgGAS studies to date, and summarizes all reported outcomes, definitions, and the times when outcomes were assessed following these surgical interventions. Aims/Methods: This work intends to quantify the levels of outcome variability and definition heterogeneity in this expanding field and provides guidance on outcome reporting for future study authors. Candidate studies for this systematic review were sourced via an electronic, multi-database literature search. All primary, clinical research studies of fgGAS were included with no date limits. Paired collaborators screened each study for inclusion and performed data extraction to document the outcomes, definitions, and times of outcome assessment following fgGAS.

Results

After screening 1225 studies, 93 studies proceeded to data extraction, representing 7681 patients. 2621 separate individual outcomes were reported, 857 (32.7%) were defined, and the time of outcome assessment was given for 1856 outcomes (70.8%) but relied on nonspecific ranges of follow-up dates. "Attainment of orgasm", "Neovaginal stenosis", and "Neovaginal depth/length" were among the most commonly reported outcomes. Profound heterogeneity existed in the definitions used for these and for all outcomes reported in general.

Discussion

The results demonstrate a need for clear outcomes, agreed definitions, and times of outcome assessment following fgGAS in transgender women and gender diverse individuals. The adoption of a consistent set of outcomes and definitions reported by all future studies of fgGAS (a Core Outcome Set) will aid in improving treatment comparisons in this patient group. This review is the first step in that process.

Robotic Sigmoid Vaginoplasty in an Adolescent Girl With Mayer-Rokitansky-Kuster-Hauser Syndrome

BACKGROUND

Sigmoid vaginoplasty has carved a niche for itself in reconstructive genitoplasty. We describe the successful use of a robotically assisted sigmoid vaginoplasty in an adolescent girl with Mayer-Rokitansky-Kuster-Hauser syndrome.

CASE

An 18-year-old girl was referred to our hospital with the complaint of primary amenorrhea. She was thoroughly evaluated and magnetic resonance imaging was done, which revealed absence of a vagina and uterus but bilateral normal ovaries. Because cytogenetic analysis was "normal 46,XX" karyotype, Mayer-Rokitansky-Kuster-Hauser syndrome was diagnosed. She was successfully managed by the use of robot-isolated sigmoid colon segment for vaginal replacement and robot-sewn colon-colon anastomosis. A follow-up was done at the 3rd and 6th months, which revealed a large capacious vagina even without self-dilatation.

CONCLUSIONS

The robotic approach is feasible and can produce satisfying postoperative outcomes and might be a minimally invasive technique in future vaginoplasty surgery.

Robotic approach to vaginal atresia repair in an adolescent girl

A 9-year-old girl presented to us, after failed perineal approach for vaginal atresia, with abdominal pain. She was thoroughly evaluated and contrast enhanced computed tomographic was done, which revealed absence of lower 1/3^rd of vagina with normal uterus, fallopian tubes and ovaries. There was no associated anomaly. She was successfully managed by a combined robotic and perineal approach. Follow-up after 6 and 12 months revealed large capacious vagina with healthy mucocutaneous junction.

[Laparoscopy-assisted vaginal pelvic exenteration]

OBJECTIVE

The aim of the study was to evaluate the feasibility, morbidity and survival outcome of laparoscopy-assisted vaginal pelvic exenteration.

PATIENTS AND METHODS

Since 2000, 7 en-bloc pelvic exenteration combining a vaginal or perineal approach and laparoscopic approach have been performed in our cancer center associated with complex laparoscopic reconstruction. All patients but one received previous irradiation. Two patients underwent a total pelvic exenteration; three patients an anterior and middle exenteration; two patients a middle and posterior exenteration. Urinary system was reconstructed with an ileal loop in one case, with a hand-assisted laparoscopic Miami pouch in four cases. Reconstruction of the vagina was performed with an omental cylinder in three cases, with a gluteal thigh flap in one case. A colorectal anastomosis was performed in three patients, one patient had an end colostomy. A mini-laparotomy conversion was necessary in one case because of a pelvic side involvement to perform an intraoperative irradiation.

RESULTS

Mean time of the procedure was 6.5 hours with peroperative bleeding less than 500 cm3. Four patients presented minor complications. No revision of the Miami pouch was necessary. Mean length of hospital stay was 27 days. The four patients with a Miami pouch were able to self catheterize at the time of discharge. Mean follow-up was 14 months. Four patients died of the disease (three were metastatic). One patient presented a local recurrence. Two patients are free of disease.

DISCUSSION AND CONCLUSION

Laparoscopic or laparoscopy-assisted vaginal pelvic exenteration followed by reconstruction is feasible with curative intent in selected patients.

Male-to-female transsexualism: Laparoscopic pelvic floor repair of prolapsed neovagina

The incidence of prolapse of the neovagina after male-to-female gender reassignment surgery is unknown. We present the first case of laparoscopic total pelvic floor repair in a male-to-female transsexual. This surgical procedure combined an understanding of the anatomy of the male pelvis with the principles of laparoscopic pelvic floor repair in the XX female.

Laparoscopy-assisted vaginal pelvic exenteration

OBJECTIVE

The aim of this study was to evaluate the feasibility, morbidity and survival outcome of laparoscopy-assisted vaginal pelvic exenteration.

METHODS

Since 2000, we have performed 5 cases of en-bloc pelvic exenteration combining a vaginal or perineal approach and laparoscopic approach. All patients had received previous pelvic irradiation. One patient underwent a total type II exenteration with ileal-loop diversion, an omental flap and a temporary colostomy. Two patients underwent a middle and posterior exenteration: one was a type III exenteration with perineal rectal resection and a gracilis myocutaneous flap; the second one was a type II exenteration with a colorectal anastomosis and a vaginal reconstruction using a gluteal thigh flap. Two patients underwent a type I anterior and middle exenteration with continent Miami pouch and vaginal reconstruction by omental cylinder.

RESULTS

Mean time of the procedure was 6 h (range: 4.5-9). Peroperative bleeding was less than 500 cm3. Two patients presented minor complications: a perineal abscess after perineal rectal resection and an abdominal wound abscess. Mean length of hospital stay was 27 days. Three patients are free of disease. Two patients presented groin metastasis. One patient died of disease after 8 months.

CONCLUSION

Laparoscopic or laparoscopy-assisted vaginal pelvic exenteration followed by reconstruction is feasible with curative intent in selected patients.

Anatomic study of vaginal width in male-to-female transsexual surgery

Despite the recent improvement in the design of male-to-female sex reassignment operations to enlarge the vaginal vault and depth, the size of the neovagina remains somewhat limited and the exterior of the neovagina may be compressed by the bony structure of pubic rami. The purpose of this study was to determine by anatomic study the possible cause of this limitation. Eighteen male and 10 female cadavers were dissected to measure the distance between the bilateral bony pubic rami (interramic distance) at a level that corresponds to the same level in the vaginal canal of females. At the same level of the vaginal canal in the female, which corresponds to the lower border of the prostate in the male, empirically 3 cm below the bony symphysis pubis, the mean value of the interramic distance was 3.95 +/- 0.25 cm in the male and 5.20 +/- 0.36 cm in the female (p = 0.000). The interramic distance in the male and female is significantly different. In those who have undergone the male-to-female transsexual operation, the newly structured vagina may be ventrolaterally limited. Several factors cause narrowing of the vaginal orifice in male-to-female transsexuals. On the basis of this study, it seems that the bony structure of the pubic rami compresses the vagina ventrolaterally. This finding may suggest refinements of the structural design of the neovagina and prompt procedural changes in male-to-female sex reassignment operations. Future investigation should be directed toward modifying vaginoplasty so that neovaginal width can be increased to the patient's satisfaction.

Secondary corrections of the vulva in male-to-female transsexuals

From December of 1980 to May of 1998, 390 male-to-female transsexuals underwent vaginoplasty by inversion of the penile skin and a triangular perineoscrotal flap. Although minor modifications were made throughout the years, the basic surgical technique remained the same over this 17.5-year period. In 86 of the 390 patients (22 percent), secondary corrections of the vulva were deemed necessary. A total of 130 corrections were performed in these 86 patients. In the same 17.5-year period, the authors performed 26 secondary corrective procedures in 19 patients in whom the initial vaginoplasty had been done elsewhere. Bilateral Z-plasties were performed 69 times to center the labia in instances when the ventral part of the labia majora remained too far apart. This is not advisable, primarily because it will reduce the vascular supply of the penile skin flap. Introital widening by five-flap advancement was performed in 40 cases in which a dorsal skin fold obstructed the introitis. The use of the triangular perineoscrotal flap favors the vaginal and introital width, but its base should be close to the anal ring to prevent such a skin fold. Secondary construction of the labia minora was performed 27 times, and a skin reduction of the labia majora was performed 20 times. So far, the authors have been unable to develop a satisfactory method for primary construction of the labia minora. Because the appearance of the vulva may charge gradually during the first postoperative year, secondary vulvar corrections should not be performed in that period.
