Surgical pearls: laparoscopic removal of uterine remnants in patients with Mayer-Rokitansky-Küster-Hauser syndrome

Endometriosis in Patients with Mayer-Rokitansky-Küster-Hauser-Syndrome—Histological Evaluation of Uterus Remnants and Peritoneal Lesions and Comparison to Samples from Endometriosis Patients without Mullerian Anomaly

Congenital Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome is a Mullerian-duct anomaly that is characterized by agenesis of the uterus and upper part of the vagina. Uterus remnants of varying sizes can often be found. Although a functional uterus is missing, the existence of endometriosis in this patient group has been described in the literature; however, a histopathological comparison of the characteristics of the endometrium within the uterus remnants versus endometriotic peritoneal lesions in the same patient is lacking. Moreover, the characteristics of endometriotic tissue in patients with MRKH syndrome have not been correlated with those of patients with endometriosis without Mullerian anomaly. Patients who underwent laparoscopic neovagina creation with the removal of uterus remnants and possible resection of endometriotic lesions between 2010 and 2022 at the Department of Women’s health of the University of Tuebingen were included in our study. Uterine remnants and endometriotic tissue were evaluated via histopathology and immunohistochemistry and were compared to endometriotic samples from patients without Mullerian anomaly. Endometriosis was detected in nine MRKH patients; in four patients, endometrial remnants could be sufficiently compared to endometriotic lesions. All samples exhibited increased expression of hormonal receptors. In two patients, Ki67 proliferation index was significantly increased in peritoneal endometriotic lesions compared with the endometrium of the remnants. In contrast, endometrium and endometriotic lesions of endometriosis patients did not exhibit any differences in the Ki67 proliferation index. Our results demonstrate distinctive immunohistochemical variability between uterine remnants and endometriotic lesions in patients with MRKH syndrome compared with patients with endometriosis, indicating a possible explanation model of the yet-unknown etiology of endometriosis. For confirmation, investigation of a broader patient collective is necessary.

Adenomyosis in a uterine horn of a patient with Mayer-Rokitansky-Kuster-Hauser syndrome

A 37-year-old woman with a previous diagnosis of Mayer-Rokitansky-Kuster-Hauser syndrome at 18 years of age was referred from a primary healthcare physician to a gynaecology appointment in our centre. She presented with a 2-year worsening pelvic pain and dyspareunia, symptoms that were previously absent and, at the time, with inadequate relief with oral analgesia. Physical examination showed absent uterine cervix and hypoplastic superior vagina. Transvaginal ultrasound and MRI suggested the presence of an hypoplasic uterus in left rotation. Laparoscopically, two asymmetric rudimentary horns were found, united by a fibrous central band, with an enlarged and congestive left horn. The three structures were removed as a whole. Histopathological examination reported the presence of multiple adenomyotic foci along the full thickness of the left rudimentary horn. The patient had an uneventful postoperative recovery and full remission of her symptoms.

Robotic-Assisted Laparoscopic Approach to Removal of Müllerian Remnants

BACKGROUND

Robotic-assisted laparoscopy (RAL) is an alternative to traditional laparoscopic surgery that might increase a surgeon's ability to offer minimally invasive removal of Müllerian remnants (MR) to patients with complex anatomy. We report on 2 cases of RAL resection of MR.

CASES

RAL allowed for adequate resection of MR without complications in 2 cases. Case 1 was a 13 year-old female adolescent with VACTERL and uterine remnant close to the ureter of her ipsilateral single kidney. Case 2 was a 16 year-old female adolescent with cloacal exstrophy and omphalocele with remnant hindgut and cervical remnant deep in the pelvis close to the ileal conduit.

SUMMARY AND CONCLUSION

In 2 adolescents with complex anatomy and surgical history, RAL allowed for successful removal of MR.

Management of Acute Obstructive Uterovaginal Anomalies: ACOG Committee Opinion, Number 779

Obstructive uterovaginal anomalies may present after puberty with amenorrhea, dysmenorrhea, pelvic pain, recurrent vaginal discharge, or infertility. The evaluation of a patient with a suspected obstructive reproductive anomaly should include a detailed medical history, physical examination, and imaging. The genital examination is critical to differentiate a patient with an imperforate hymen from a patient with labial adhesions, urogenital sinus, transverse vaginal septum, or distal vaginal atresia. Pelvic ultrasonography is the initial imaging method recommended for a patient with cyclic pain and amenorrhea or a patient with persistent dysmenorrhea. It is important to note that diagnosis of a uterine or vaginal anomaly by imaging before puberty can be challenging and misleading because of the small size of the prepubertal uterus and the lack of endometrial stimulation and menstrual distention of the vagina. Consultation with a radiologist experienced with imaging of uterovaginal anomalies may be helpful to determine the most accurate diagnosis. In general, obstructive vaginal and uterine anomalies are not surgical emergencies, and the complexities of these conditions are best managed by gynecologic care providers familiar with the surgical management of these conditions. Given the high risk of stenosis and complications associated with transverse vaginal septum, distal vaginal atresia, and cervical atresia, referral to a center with expertise in the management of these anomalies is paramount. The best long-term outcome is achieved with a complete evaluation, clear understanding of the anomaly, mobilization of appropriate surgical resources, sufficient preoperative counseling, and planned surgical intervention.

Postoperative evaluation of chronic pain in patients with Mayer - Rokitansky - Küster - Hauser (MRKH) syndrome and uterine horn remnant: Experience of a tertiary referring gynaecological department

INTRODUCTION

Patients with Mayer - Rokitansky - Küster - Hauser (MRKH) syndrome often experience chronic pelvic pain negatively impacting their life's quality. Our understanding of the factors involved in this symptom remains poor. The aim of our study was to further investigate the different components of this pelvic pain in patients with MRKH undergoing pelvic surgery. Our second objective was to assess the evolution of this pain in patients undergoing surgical removal of their uterine horn remnant.

MATERIAL AND METHODS

We conducted a retrospective analysis of a cohort of patients treated in our tertiary referring gynaecological department. Patients included had a MRKH syndrome with at least one uterine horn remnant and all underwent at least one surgical procedure in our centre. Descriptive analysis of the main characteristics and of the management of these patients was conducted. Postoperative pain was evaluated using simple words and / or analgesic consumption evaluation.

RESULTS

Between 1991 and 2013, twenty-one patients were included in our centre. Out of them, 20 (95 %) had chronic pelvic pain, mostly cyclic pain lasting 2-3 days. Fourteen patients had surgical removal of their uterine horns remnant and only 3 patients (21 %) had persistent pain at their postoperative visit. Surgical findings included peritoneal endometriosis in 8 patients (38 %) and other unexpected findings in 6. At pathological analysis, secretary endometrium in the uterine horn remnant was found in 11 patients (79 %).

CONCLUSION

The origin of chronic pain in MRKH is combining several factors such as endometriosis or secretary endometrium. Surgical removal of uterine horn remnant improved most of our patients' pelvic chronic pain. Further studies should help improve our understanding of this specific entity.

Assessing the Experience of Vaginal Dilator Use and Potential Barriers to Ongoing Use among a Focus Group of Women with Mayer-Rokitansky-Küster-Hauser Syndrome

STUDY OBJECTIVE

To assess the experience of dilator use for neovagina creation in women diagnosed with Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome and identify barriers affecting patient compliance with dilator use.

DESIGN AND SETTING

This was a qualitative study using a structured questionnaire to investigate perception and identify barriers regarding vaginal dilator use. A questionnaire was administered after participants viewed a 2-minute patient educational video to additionally examine the usefulness of a patient education video tool as an adjunct to counseling in clinic on vaginal dilator use.

PARTICIPANTS, INTERVENTIONS, AND MAIN OUTCOME MEASURES

We enrolled 13 adolescent girls and women diagnosed with MRKH, aged 14-48 years, recruited from clinic and during a conference geared toward women affected by MRKH.

RESULTS

The mean age of participants was 26 (±11.4) years with most diagnosed between the ages of 12 and 18 years. Of all participants, 69% (9/13) reported ever being sexually active with a mean age of coitarche of 16 (±2.6) years. Seventy-seven percent (10/13) reported current or past use of vaginal dilators, and most had some previous education on dilator use. Only 15% (2/13) reported no previous exposure to an educational tool. After viewing the 2-minute educational video, all participants rated it very helpful using a Likert scale (strongly agree to strongly disagree). Major themes that emerged as perceived barriers to dilator use included viewing dilation as a negative experience, uncertainty about success, and lack of motivation.

CONCLUSION

Education is an integral part of improving compliance with vaginal dilator use among adolescent girls and women affected by MRKH. Technology can be used to reinforce face-to-face counseling in the clinic. To our knowledge, this is the first study to specifically investigate patient experience with dilator use and opinion regarding the use of video technology to demonstrate self-directed neovagina creation in an MRKH population. The barriers identified in this study provide new insights to inform future research and clinical management of dilator use.

Laparoscopic Outcomes for Pelvic Pathology in Children and Adolescents among Patients Presenting to the Pediatric and Adolescent Gynecology Service

STUDY OBJECTIVE

The aim of this study was to evaluate surgical indications, outcomes, and common pelvic pathologies presenting to the Pediatric and Adolescent Gynecology service in premenarcheal (PMF) and menarcheal females (MF) undergoing laparoscopic surgery.

DESIGN

A retrospective chart review.

SETTING

An academic children's hospital.

PARTICIPANTS

Females under 21 years of age, excluding pregnant patients, who underwent laparoscopic surgery for a gynecologic indication presenting to the Pediatric and Adolescent Gynecology service at a single children's hospital between July 2007 and January 2012, identified by CPT codes.

MAIN OUTCOME MEASURES

Pertinent patient demographics, indication for surgery, anesthesia time, estimated blood loss, surgical instruments used, intra-operative findings, surgical pathology, complications, length of stay, and concerns at follow-up appointment. Descriptive statistics and chi-square analyses of data were performed using SAS 9.3.

RESULTS

Of 158 cases meeting inclusion criteria, 33 patients were PMF (mean age 8.6 ± 3.2 years) and 125 patients were MF (mean age 14.7 ± 2.3 years). Acute abdominal pain was the most common surgical indication in both groups, but was significantly more likely to be the surgical indication in the PMF group (62.7% vs. 52.8%, P = .006). Adnexal torsion was more likely to be present in the PMF group than in the MF group (66.7% vs. 27.2%, P < .0001). No complications were reported in the PMF group. Two minor complications were reported in the MF group.

CONCLUSION

Minimally invasive surgical techniques represent a safe and well-tolerated method for treating a wide variety of pelvic pathology in both younger children and older adolescent females. For physicians evaluating premenarcheal females with acute-onset abdominal pain, adnexal torsion should be prominent among the differential diagnoses.

Endometriosis in a patient with mayer-rokitansky-küster-hauser syndrome

Objective. To report a case of Mayer-Rokitansky-Küster-Hauser syndrome (MRKH) in which there were two nonfunctional rudimentary uteruses with the presence of ovarian endometrioma, corroborating that there are valid alternative theories to the existence of endometriosis, rather than Sampson's theory alone, such as the coelomic metaplasia theory. Design. A case report. Setting. A tertiary referral center, which is also a university hospital. Patient. A fifteen-year-old patient with MRKH syndrome and endometriosis. Intervention. Laparoscopic approach for diagnostic confirmation and treatment of the endometrioma. Results. Evidence of endometriosis in a patient with no functional uterus. Conclusions. This case report and a few others that are available in the literature reinforce the possibility that coelomic metaplasia could be the origin of endometriosis. Patients with müllerian agenesis and pelvic pain should be carefully evaluated, and the presence of pelvic endometriosis should not be excluded.
