Levonorgestrel-releasing intrauterine system versus oral medroxyprogesterone acetate in infertile women with endometrial hyperplasia without atypia.

RESEARCH QUESTION: How does use of a levonorgestrel-releasing intrauterine system (LNG-IUS) in infertile women with endometrial hyperplasia without atypia affect endometrial hyperplasia regression and pregnancy rates compared with oral medroxyprogesterone acetate (MPA)? DESIGN: This prospective cohort study included 215 infertile women with an indication for assisted reproductive technology (ART) and a diagnosis of endometrial hyperplasia without atypia. Endometrial hyperplasia was diagnosed by hysteroscopic endometrial biopsy. At the time of first- and second-line treatment, patients were offered therapy with either oral MPA 10 mg daily or LNG-IUS. Follow-up biopsies were scheduled after 90 days' treatment. After endometrial hyperplasia regression, patients were admitted to IVF/intracytoplasmic sperm injection (ICSI) cycles. RESULTS: Baseline characteristics and confounders including age at diagnosis, body mass index and duration of infertility did not differ between LNG-IUS users and control participants and were accounted for using propensity score weighting. Endometrial hyperplasia regression rate at first follow-up was higher in the LNG-IUS group than the oral progestins group (28/28, 100% and 110/187, 58.8%; P < 0.001), while that after second-line treatment was comparable between the two groups (89/91, 97.8% and 122/124, 98.4%; P = 0.22). Clinical pregnancy rate, miscarriage rate and cumulative live birth rate following ART in patients ever receiving LNG-IUS were similar to those of patients receiving only MPA (34% versus 39.5%, 22.6% versus 34.7% and 26.4% versus 25.8%). CONCLUSION: Endometrial hyperplasia regression is greater in women receiving LNG-IUS compared with oral MPA, while live birth rates following ART are comparable between the two groups. The use of LNG-IUS does not jeopardize the chances of pregnancy in women seeking fertility treatment.

Oocyte Retrieval during Laparoscopic Vaginoplasty to Reduce Invasiveness in the Treatment of Mayer-Rokitansky-Küster-Hauser Syndrome.

STUDY OBJECTIVE: To evaluate the treatment of patients with Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome with a combination of oocyte retrieval and surgical vaginoplasty in a single laparoscopic procedure. DESIGN: A case series. SETTING: The study was conducted at 2 tertiary referral facilities for MRKH syndrome in Milan, Italy, between July 2017 and September 2018. PATIENTS: Eleven patients presented with MRKH and required surgical vaginoplasty while expressing a desire for future fertility. INTERVENTIONS: Two experienced surgeons and an expert in assisted reproductive technology performed concomitant vaginoplasty according to the modified technique of Davydov and laparoscopic oocyte retrieval for gamete cryopreservation. MEASUREMENTS AND MAIN RESULTS: Before the procedure, patients underwent extensive counseling and gave written consent. At the start of surgery, 10.4 ± 4.4 (mean ± standard deviation [SD]) oocytes were retrieved laparoscopically, and 8.8 ± 3.1 (SD) mean mature oocytes were cryopreserved. After oocyte retrieval, the steps of the modified Davydov technique were followed. The total operative time was 116 ± 16 minutes (mean ± SD), and no intraoperative/postoperative complications were observed. CONCLUSION: This is the first report of combined oocyte retrieval and vaginoplasty for patients with MRKH syndrome. The approach was found to be feasible in patients with a desire for future fertility. It is our belief that physicians treating patients with MRKH should refer patients to centers with expertise in both vaginoplasty and assisted reproductive technology.

Flexible CO2 laser fiber: first look at the learning curve required in gynecological laparoscopy training.

BACKGROUND: The advent of flexible CO2 laser fiber to gynecology arena might represent a turning point in the use of laser energy on a large-scale basis in gynecological surgery. However, there might be some concerns regarding the degree of surgical skills required to use the flexible system. The purpose of our study is to evaluate whether flexible CO2 laser fiber is technically accessible. METHODS: Fourteen residents in Obstetrics and Gynecology without surgical experience attending laparoscopic box training with both flexible CO2 laser fiber and traditional line-of-sight CO2 laser using Lumenis AcuPulse Duo CO2 laser (Lumenis, Yokne'am Illit, Israel) were prospectively enrolled. Participants were tested at sequential time points on specific surgical tasks and results obtained with the flexible CO2 laser fiber and the traditional line-of-sight CO2 laser were compared. Results were compared by means of paired t-test and a two-tailed P value <0.05 was considered significant. RESULTS: Mean grading at the beginning of training were similar between flexible fiber and line-of-sight CO2 laser. At the end of training, significant improvement in surgical skills was obtained for both techniques, with a statistically significant higher grading for flexible fiber CO2 laser compared to line-of-sight CO2 laser. CONCLUSIONS: Our study found that residents without surgical experience show better skills with the flexible CO2 laser fiber delivery system compared to the standard line-of-sight CO2 laser system after a two-month training period with gynecological laparoscopic box. According to our results, flexible CO2 laser fiber delivery system is technically accessible and holds a potential in gynecological surgery.
