Surgical excision of advanced endometriosis has been demonstrated to improve women's pain symptoms and quality of life in women in randomized placebo-controlled trials, but there is no strong evidence regarding the live birth rate. The revised American Fertility Society (r-AFS) classification for endometriosis has a limited predictive ability for fertility outcomes after surgery; therefore, EFI scoring has been advised for predicting conception after endometriosis surgery. No randomized controlled trials have investigated fertility outcomes in patients with advanced endometriosis after surgery.

Objectives: The purpose of the study is to investigate potential association of chorionic villus sampling CVS) with subsequent development of preeclampsia (PE) and eclampsia (E).

Study Design: The development of PE and E was compared between two groups as follows: 1- CVS group: women who underwent CVS ( = 228) and 2- Control group: maternal and gestational age matched women without invasive prenatal diagnostic procedure ( = 456). Main outcome measures were incidence of PE (mild, severe) and E.

Aim: The objective of this study was to present our experiences of tissue extraction via the transvaginal (TV) route after a mini-laparoscopic gynecological surgery and compare them with our transabdominal (TA) specimen extraction experiences.

Methods: This prospective randomized controlled study was conducted in a tertiary care center between July 2014 and February 2016. Fifty-eight women who were undergoing mini-laparoscopy for adnexal mass removal were randomized into two groups according to the surgical specimen removal by the TV route (n = 28) or the TA route (n = 30).

Atherosclerosis is a systematic disease affecting all arteries and is the most common cause of mortality. Our aim was to evaluate the predictive value of the presence of uterine arcuate artery calcification (AAC) for coronary heart disease (CHD) in women. Seventy women presenting with angina pectoris or a finding suggestive of cardiac ischaemia in non-invasive tests, scheduled for angiography between June 2014 and July 2015 were recruited in the study.

Background: In gynecological surgery, one particular area of concern after hysterectomy is the risk of developing an enterocele or vaginal apical prolapse. The aims of this study were to evaluate the safety and efficacy of prophylactic McCall culdoplasty (MC) performed during mini-total laparoscopic hysterectomy (mini-TLH), as well as to compare the differences in apical support, total vaginal length (TVL), and sexual function at one and two years postoperatively.

Methods: Data were retrospectively reviewed for all women who underwent mini-TLH and mini-TLH + MC at a tertiary care center between August 2012 and January 2016 were from the hospital database.

Introduction: Fetal nasal bone hypoplasia has been proven to be a strong marker for trisomy 21 during second trimester ultrasonography. Rather than evaluating the nasal bone hypoplasia according to the nomograms, it may be possible to evaluate it with a more practical and specific method.

Material And Methods: Retrospectively collected data were provided from the saved and stored patient data between 2012 and 2017.

An important open question in the literature is whether endometrial receptivity marker levels are different in infertility related diseases than healthy women. The aim of the study is to compare the levels of interleukin two (IL-2) and tumor necrosis factor alpha (TNF-α) during the implantation window in the endometrial flushing fluid of polycystic ovary syndrome (PCOS), endometrioma, leiomyoma patients with healthy controls. In this case control study, after obtaining endometrial flushing fluids at mid-luteal phase of ovulatory women with PCOS (n = 20), endometrioma (n = 19), leiomyoma (n = 20) and healthy controls (n = 20), IL-2 and TNF-α levels were measured using ELISA kits in BioTek ELISA devices.

Background: Prenatal screening for aneuploidies has seen great changes over the last 2 decades. But there is still no non-invasive diagnostic test. Therefore, prenatal invasive procedures are still being routinely performed due to maternal anxiety.

To compare Anti-Mullerian hormone (AMH) concentrations between polycystic ovary syndrome (PCOS)  patients and  healthy women who have polycystic ovarian morphology (PCOM) with regular menstrual cycles, and to determine a diagnostic cutoff value for PCOS women during reproductive period. Methods: This  study was carried out between February 2013 and October 2017 at the Department of Obstetrics and Gynecology, İzmir Katip Çelebi University Atatürk Training and Research Hospital,  Izmir, Turkey. Seventy PCOS patients and 70 PCOM women with normal menstrual cycles were included in the study.

It has been realised that rhythmic peristalsis of the ostia and tubes can be observed during hysteroscopy. The aim of this study was to examine the presence of tubal peristaltic dysfunction in unexplained infertility (UI). Hysteroscopy was performed in 35 women with UI and in 37 healthy fertile women.

Introduction: To compare both the prevalence of gestational diabetes mellitus (GDM) as well as maternal and neonatal outcomes by either the one-step or the two-step approaches.

Material And Methods: Electronic databases were searched from their inception until June 2017. We included all randomized controlled trials (RCTs) comparing the one-step with the two-step approaches for the screening and diagnosis of GDM.

Objectives: The diagnosis of ectopic pregnancy has been facilitated especially by the use of Doppler ultrasonography. In previous studies the presence of peri-trophoblastic blood flow by Doppler ultrasound and the detection of a low-resistance, high-velocity flow pattern were defined as specific signs for trophoblastic tissue. The aim of this study was to evaluate the efficacy of Doppler ultrasonography in the prediction of treatment success in tubal pregnancies being treated with single dose conservative methotrexate.

Objective: The reasons why endometriosis is more aggressive and invasive in some patients are unknown. Despite the importance of population-based clinically defined risk factors in the prediction of recurrence, biochemical markers obtained from the patient are more valuable for prediction on an individual basis. Therefore, the discovery of significant potential biomarkers could be useful to clinicians for shedding light on the pathogenesis of endometriosis and in the monitoring recurrence.

Background: Minimally invasive endoscopic surgery has become an acceptable method for gynecologic indications for more than 20 years. We aimed to compare clinical and surgical outcomes between mini-laparoscopic surgery (MLS) and conventional laparoscopic surgery (CLS) for benign adnexal masses. As far as we know, no comparative study exists between these two minimal invasive procedures.

Total Laparoscopic Hysterectomy (TLH) represents one of the most performed gynaecological procedures nowadays. The closure of the vaginal cuff is the most diffucult part of TLH because of the difficulty of laparoscopic suturing techniques. Our aim was to evaluate the efficacy and safety of vaginal cuff closure by vaginal route on patients submitted to TLH.

The aim of this cross-sectional study is to compare endometrial flushing fluid levels of αβ integrin, glycodelin and PGF2α during the midluteal phase of the menstrual cycle of women with polycystic ovary syndrome (PCOS, n = 20), myoma uteri (n = 20) and endometrioma (n = 19) with the healthy controls (n = 20). After collecting samples at the midluteal phase of ovulatory volunteers and storing them at -80 °C, αβ integrin, glycodelin and PGF2α levels were analyzed using ELISA. The mean ages of the groups were 28.

Uterine lipoleiomyomas are rare benign tumours that are composed of various mixtures of smooth muscle and mature fat tissue. Leiomyomas, which arise primarily in the ovary, are extremely rare tumours that account for 0.5-1% of all benign ovarian tumours.
