The role of hydrodissection in native tissue repair of anterior vaginal wall defects.

AIMS: A variety of surgical techniques are available for vaginal prolapse repair, indicating a lack of consensus. A debate regarding the utility of hydrodissection for splitting the surgical plane of the vaginal wall exists. The aim of this study is to evaluate the impact of hydrodissection in anterior colporrhaphy (AC). MATERIALS: Patients undergoing primary AC were randomly assigned to an approach with (study group) versus without (control group) hydrodissection. Five surgeons performed both techniques, and the trimmed vaginal tissue was retrieved for histological analysis. Two pathologists, blinded to the surgical approach, evaluated the presence of a loose connective tissue at the surgical dissection plane (controversially deemed 'fascia', as explained in this article). In addition, we compared the operative time, pain score and haemoglobin levels. After statistical analysis, data were presented using percentile, and statistical significance was tested using the χ2 and Fisher's exact tests. RESULTS: Forty-six patients underwent primary elective AC, with 23 patients in each, the study and control groups. The groups were comparable regarding age (study group 60.33 ± 11.95 years and control group 59.86 ± 12.04, P = 0.90), menopausal status (study group 17 (73.9%) and control group 15 (68.2%), P = 0.67) and other characteristics. We found no difference in sample characteristics between the two groups. Connective tissue was found in only 13.6% (n = 3) of patients after hydrodissection and in 27.3% (n = 6) of patients without hydrodissection (P = 0.46). The hydrodissection group had significantly less bleeding than the control group (ΔHB 0.66 ± 0.66 vs 1.21 ± 0.84, P = 0.05). CONCLUSIONS: After hydrodissection, less bleeding was noted without compromise the surgical planes.

The correlation between endometrial thickness and the criteria for MTX treatment for ectopic pregnancy.

Ectopic pregnancy (EP) occurs in approximately 2% of all pregnancies. A common method of treatment is methotrexate therapy, considered in haemodynamically stable patients. Endometrial thickness has been investigated as a tool for diagnosing EP. The objective of this study was to evaluate the association between endometrial thickness and the criteria for MTX treatment, in an attempt to facilitate outcome prediction. We retrospectively collected data from records of patients diagnosed with EP between 2012 and 2014 including information regarding the mode of treatment and outcome. The endometrial thickness was compared between cases that met the criteria for MTX treatment and those who did not. Of 267 cases of EP that were reviewed, 108 patients were treated with MTX. The MTX treatment success rate was 88%. Endometrial thickness was found to be significantly and inversely associated with criteria for MTX treatment. In conclusion, an association was found between the endometrial thickness and the criteria for selection of MTX treatment for EP. This may be a useful tool in treatment selection for EP.Impact StatementWhat is already known on this subject? Transvaginal sonography along with ß-human chorionic gonadotrophin (ß-hCG) monitoring is the standard for evaluation of suspected ectopic pregnancy (EP). The most specific sonographic finding for EP is the presence of a live extra uterine pregnancy. In research conducted with the purpose of finding intrauterine sonographic findings associated with EP, this condition has been shown to be correlated with a thinner endometrial lining, compared with that of an intrauterine pregnancy.What the results of this study add? The results of this study add information on the subject of methotrexate treatment success rates in correlation with the endometrial thickness.What the implications are of these findings for clinical practice and/or further research? The findings of this study contribute to the process of treatment selection for ectopic pregnancy by emphasising the association between a thick endometrium and the lower success rates of MTX treatment.

Pelvic floor disorders following different delivery modes-a population-based cohort analysis.

INTRODUCTION AND HYPOTHESIS: Identifying protective factors against pelvic floor disorders (PFDs) is important. We investigated whether cesarean delivery (CD) at the indication of abnormal second stage of labor (ASSL) has the same protective effect against future PFDs. METHODS: This population-based cohort study included deliveries occurring from 1991-2017 in a tertiary medical center. Women were grouped by their delivery mode: patients with vaginal deliveries (VD) only; those with CD only, excluding second-stage indications; and those with CD due to ASSL. The outcome measure, PFDs and related repair diagnoses, included any recorded hospitalization involving a pre-defined set of ICD-9 codes. A Kaplan-Meier survival curve compared cumulative PFD morbidity in the different groups, and a Cox proportional hazards model controlled for confounders. RESULTS: A total of 106,003 patients met the inclusion criteria; 86.7% (n = 91,856) experienced VD only, 11.7% (n = 12,359) underwent CD only and 1.7% (n = 1788) had at least one CD due to ASSL. PFD-related hospitalization incidence was 0.7% (n = 719) for the entire cohort. While a significantly higher PFD-related hospitalization rate was recorded in the VD group (0.7%) compared with the ASSL CD group (0.3%) and the non-ASSL CD group (0.5%, p < 0.001), after controlling for potential confounders, an independent and protective association was noted between CD and later PFDs only in parturients who did not experience ASSL (aHR 0.679, 95% CI 0.51-0.90, p = 0.006). CONCLUSIONS: CDs may be protective against later PFD development only if performed prior to the second stage of labor.

Long-term outcome (5-10 years) after non absorbable mesh insertion compared to partially absorbable mesh insertion for anterior vaginal wall prolapse repair.

OBJECTIVE: To evaluate long-term (5-10 years) outcomes of Minimally Invasive Surgical (MIS) kit insertion with Prolift® (non-absorbable) mesh compared to the use of Prolift M® (partially absorbable), for anterior vaginal wall prolapse repair. STUDY DESIGN: In this retrospective study we compared women undergoing MIS kit Prolift ® insertion (n=90) vs. Prolift M® insertion (n=79) for anterior vaginal wall prolapse repair between 2006 and 2012 at our Institution. A number of 169 women fulfilled the inclusion criteria and were included in the study. RESULTS: During the study period 128 women (76%) completed full follow-up; of them 58 (73%) following MIS kit Prolift® insertion, and 70 (88%) following MIS kit ProliftM® insertion. There was no signifi cant difference between the Prolift® and Prolift M® regarding parity (3.04 vs. 2.88, p=0.506), presence of hypertension (24.1% vs. 39.1%, p=0.088), diabetes mellitus (3.4% vs. 11.6%, p=0.109), or urinary stress incontinence (39.7% vs. 47.1%, p=0.475). All participants had been diagnosed with POP grade 3 or 4 before the procedure. No significant complications during the procedure or postoperative period were identified in the study groups. The follow-up period was at least five years in duration for both groups. Both groups were comparable according to questionnaires focused on function and satisfaction. CONCLUSION: Patients undergoing MIS kit Prolift® and Prolift M® insertion for anterior vaginal wall prolapse repair had comparable early and late postoperative outcomes. No differences in patient's function and satisfaction between the two groups were identified. According to our fi ndings, there is no superiority to either of the two studied mesh devices.

Postpartum uterine artery blood flow impedance following cesarean section or vaginal delivery.

PURPOSE: To compare uterine arteries (UtA) blood flow after cesarean section (CS) or vaginal delivery (VD). METHODS: We performed a prospective case-control study comparing UtA blood flow impedance in patients who delivered by CS or VD. The UtA pulsatility index (PI) was measured with Doppler ultrasound during post partum using a transabdominal convex probe. Maternal and gestational age, parity, gravidity, and delay between delivery and Doppler measurement were noted. RESULTS: We examined 106 postnatal patients, of whom 35 had CS delivery and 71 had VD. The median delay from delivery to Doppler measurement was 35 hours for the CS group and 32 hours for the VD group. The mean PI following CS and VD was 1.62 ± 0.45 and 1.42 ± 0.47, respectively. Using a linear model, the regression coefficients for mean, right, and left PI were not significantly different depending on the mode of delivery. There was no difference between emergency and elective CS. CONCLUSIONS: Early postpartum UtA blood flow impedance is not significantly different after CS or VD. © 2015 Wiley Periodicals, Inc.

The effect of non-obstetric invasive procedures during pregnancy on perinatal outcomes.

PURPOSE: To evaluate the effect of non-obstetric invasive procedure during pregnancy on perinatal outcome. METHODS: The present retrospective study investigated perinatal outcome in women that underwent an invasive procedure during one of their pregnancies (n = 61); perinatal outcome was compared to other pregnancies (without an invasive procedure) of the same patients (n = 122). RESULTS: Women with a non-obstetric invasive procedure during pregnancy delivered earlier than those in the comparison group (38.5 vs. 40.0 weeks; p = 0.01) and had a significantly higher rate of cesarean sections (18 vs. 5 cases; p < 0.01). In addition, birth weight was significantly lower in patients undergoing invasive procedures during pregnancy (2908.65 vs. 3185.84 gr; p = 0.02). The absolute rate of prematurity (<37 weeks) was non-significantly higher in the study group (18.3 vs. 10.0 %; p = 0.28). CONCLUSION: Non-obstetric invasive procedures are associated with an increased rate of cesarean sections and lower birth weight. Nevertheless, no significant differences in early perinatal outcome were found in comparison to other pregnancies of the same patients. More studies are needed to evaluate the outcome following specific procedures.

Ectopic pregnancy in uterosacral ligament following in vitro fertilisation (IVF) in a patient with Allen-Masters syndrome.

We describe the case of a woman with mild endometriosis and Allen-Masters syndrome after in vitro fertilisation (IVF), presenting at 7 weeks 2 days gestation with abdominal pain. A transvaginal ultrasound revealed a gestational sac with a non-viable fetus near the right ovary. Laparoscopy was performed due to escalating abdominal pain which revealed a ruptured ectopic pregnancy at the right uterosacral ligament (USL) and blood in the pouch of Douglas. A peritoneal incision along the USL facilitated drainage and removal of the ectopic pregnancy. A pathological investigation described the presence of endometrial tissue directly adjacent to products of conception, which suggested a retroperitoneal implantation that may have been facilitated by the presence of an endometriotic lesion. This case underscores the distinctive clinical trajectory of unconventional ectopic pregnancies, provides novel insights into the pathophysiological mechanism of ectopic implantation and underscores the crucial role of comprehensive patient assessment during IVF and subsequent pregnancy in ensuring effective management.

Influence of ovarian torsion on reproductive outcomes and mode of delivery.

Purpose: To investigate differences in reproductive outcomes among patients before and following ovarian torsion. Study design: In this retrospective cohort study, we investigated the reproductive outcomes of patients who underwent surgery for ovarian torsion between 1988 and 2015 in a tertiary medical center. Data on deliveries before and after ovarian torsion were compared. Results: During the study period, 199 women underwent surgery due to ovarian torsion. The majority (91.4%; n = 182) underwent detorsion, and 8.6% (n = 17) underwent unilateral adnexectomy. At the time of the torsion, 27.6% (n = 55) of patients were pregnant. Among women who suffered from ovarian torsion, about half (52%) of the deliveries occurred before the torsion and 48% following the torsion. No significant difference in the live birth rate was noted (p = 0.19). The fertility treatment rate in our cohort was 7.5% before and 5% after the torsion (p = 0.01). In addition, live birth, cesarean delivery, and fertility treatment rates were similar in women who underwent detorsion vs. those who had adnexectomy. Conclusion: Surgically treated ovarian torsion does not appear to negatively influence fertility and live birth potential.

Subsequent pregnancy outcomes after abdominal vs. laparoscopic myomectomy.

OBJECTIVE: To determine whether abdominal (open) vs. laparoscopic myomectomy affects the obstetrical outcomes of subsequent pregnancies. METHODS: A retrospective cohort study was conducted at a tertiary university medical center. The study population included women who had a documented birth following a myomectomy at our institution between the years 1997 and 2018. The obstetrical characteristics and immediate perinatal outcomes of the subsequent pregnancy following open vs. laparoscopic myomectomy were collected and compared. Data were retrieved from patients' medical records via the institutional computerized database. Cases that lacked detailed surgery and delivery reports were excluded. Data were analyzed using a chi-square test for categorical variables and one-way ANOVA for continuous variables. A p-value <.05 was considered statistically significant. RESULTS: During the study period, 57 women met the inclusion criteria, of whom 66.6% (38/57) had an open and 33.3% (19/57) had a laparoscopic myomectomy. Women who underwent an open myomectomy had a higher rate of cesarean birth than those in the laparoscopic group (89.5 vs. 42.1%, p < .001). No cases of severe maternal or perinatal complications, uterine ruptures, or placental abruptions were identified in either study group. No other significant differences were noted between the two types of myomectomy. CONCLUSION: Open myomectomy is associated with a higher rate of cesarean delivery than laparoscopic. No severe adverse maternal or neonatal outcomes were detected in either study group.

Obstetric Outcomes after Perforation of Uterine Cavity.

We aimed to evaluate the pregnancy characteristics and obstetric outcomes in patients after perforation of the uterus. Study design: A retrospective cohort study was conducted and included all patients who were diagnosed with uterine perforation and treated in a tertiary referral medical center between the years 1996 and 2018. Up to two deliveries after perforations were investigated. Results: During the study period, 51 women were diagnosed with uterine perforation during gynecological procedures, including intrauterine device (IUD) insertion. The mean age of patients at the time of diagnosis was 27.9 (±4.7) years. The majority, 76.5% (n = 39), experienced perforation during IUD insertion, and 23.5% (n = 12) of the patients experienced perforation during surgical procedures. Most of the patients were multiparous or grand multiparous, 45.8. % (n = 22) and 39.6% (n = 19) respectively. Anteflexed uterus was found in 86.4% of the patients (n = 38). Five patients (9.8%) had pelvic abscesses after the IUD insertion. A total of 50 patients had 71 deliveries subsequent to uterine perforation. One patient experienced intrauterine fetal death due to fetal malformations. One patient experienced uterine rupture. No other major obstetric complications were noted. Conclusions: Uterine perforation may be associated with adverse obstetric outcomes. The possibility of uterine rupture must be considered while managing the deliveries of patients after uterine perforation. Moreover, a larger cohort and further studies are needed to establish an association between uterine perforation and adverse outcomes of the subsequent deliveries.

Maternal history of recurrent pregnancy loss and long-term risk of thromboembolic events.

BACKGROUND: Recurrent pregnancy loss is a multifactorial disorder with potential underlying maternal hypercoagulability. OBJECTIVE: We aimed to investigate whether a history of recurrent pregnancy loss poses an independent risk for future maternal long-term thromboembolic morbidity. STUDY DESIGN: A population-based study compared the incidence of long-term thromboembolic morbidity in a cohort of women with and without a history of recurrent pregnancy loss. Data were collected from two databases that were cross-linked and merged: a computerized hospitalization database and a computerized obstetrics and gynecology perinatal database. Deliveries occurred between the years 1991-2017. The risk for long-term thromboembolic morbidity was based on the hospital's database and a pre-defined set of ICD codes of thromboembolic related hospitalizations. A Kaplan-Meier survival curve was constructed to compare the cumulative incidence of significant thromboembolic morbidity in the exposed and unexposed groups, and a Cox proportional hazards model, to control for confounders. RESULTS: During the study period, 123,791 parturients met the inclusion criteria; 6.7 % n = 8247 of which experienced previous recurrent pregnancy loss-the exposed group. The rate of thromboembolic related hospitalizations was almost double in exposed women as compared to non-exposed 1.1 % vs. 0.6 %, OR = 1.8; 95 % 1.4-2.2; p < 0.001). Cumulative thromboembolic event incidence, as depicted in the survival curves, was also significantly higher among patients with recurrent pregnancy loss history (Log rank p < 0.001). The Cox model confirmed recurrent pregnancy loss history to be an independent risk factor for later maternal thromboembolic morbidity, while controlling for maternal age, known thrombophilia, ethnicity, smoking, hypertension, diabetes, and fertility treatment (aHR 1.27, 95 %CI 1.02-1.59, p=0.034). CONCLUSION: A history of recurrent pregnancy loss is an independent risk factor for long-term thromboembolic morbidity, even in the absence of known maternal thrombophilia.

Vacuum Extraction in Preterm Deliveries and Long-Term Neurological Outcome of the Offspring.

BACKGROUND: Concern exists regarding a possible harmful impact of vacuum extraction on the preterm newborn. We aimed to evaluate the long-term pediatric neurodevelopmental outcomes of the preterm offspring after vacuum extraction. METHODS: A population-based cohort analysis was performed comparing the risk for long-term neurological morbidity (up to age 18 years) in preterm (less than 37 completed weeks of gestation) children born via following three delivery modes: vacuum extraction, spontaneous delivery, and Caesarean delivery performed during the second stage of labor. A Kaplan-Meier survival curve was used to compare the cumulative neurological morbidity in all groups. A Cox proportional hazards model was used to control for confounders. RESULTS: During the study period 11,662 preterm newborns met the inclusion criteria, 97.2% (n = 11,338) of which were born via spontaneous vaginal delivery, 2.3% (n = 267) underwent vacuum extraction, and 0.5% (n = 57) were delivered by Caesarean section during the second stage of labor. Gestational age at delivery median (range) was 36 (29 to 36) weeks for vacuum extractions, 36 (23 to 36) for spontaneous vaginal delivery, and 35 (29 to 36) for Caesarean delivery within second stage of labor. Total pediatric hospitalizations involving neurological diagnoses were comparable between the groups as were the cumulative incidences of total neurological morbidity in the survival curves (log rank P = 0.723). In the Cox regression model, vacuum delivery in preterm newborns was not found to be associated with later pediatric neurological hospitalizations. CONCLUSIONS: Vacuum extraction performed on preterm newborns does not appear to be independently associated with severe long-term neurological morbidity, as reflected by later pediatric hospitalizations.

Overactive Bladder Syndrome: Evaluation and Management.

Overactive bladder (OAB) syndrome is a chronic medical condition which has a major influence on the quality of life in a significant amount of the population. OAB affects performance of daily activities and has an estimated prevalence of 16.5%. Many sufferers do not seek medical help. Moreover, many family physicians and even gynecologists are not familiar with this issue. Usually patients suffer from OAB in advanced age. Nocturia is reported as the most bothersome symptom in the elderly population. The aim of our review was to discuss all aspects of this challenging disorder and suggest tools for assessment and management strategies. Practitioners can easily overlook urinary complains if they not directly queried. We would like to encourage practitioners to give more attention to this issue.

Comparative analysis of early adverse events of pelvic organ prolapse repair with or without transvaginal mesh using Clavien-Dindo classification.

OBJECTIVE: To assess adverse events following surgical repair of pelvic organ prolapse (POP) with or without the use of transvaginal mesh. METHODS: The present retrospective study was conducted among women who underwent surgical POP repair at Soroka University Medical Center, Beer Sheva, Israel, between January 1, 2013, and December 31, 2015. Patients underwent anterior and posterior colporrhaphy either with transvaginal mesh (Elevate Prolapse Repair System; American Medical Systems, Minnetonka, MN, USA) or without transvaginal mesh (native tissue repair). Perioperative adverse events were assessed using the Clavien-Dindo classification; multivariate regression models were constructed to predict minor and major adverse events. RESULTS: There were 111 women included; 35 were treated with transvaginal mesh, and 76 underwent native tissue repair. Women undergoing native tissue repair had a lower mean grade of cystocele (P=0.023) and a higher rate of urinary stress incontinence (P=0.017) than patients treated with transvaginal mesh. The duration of surgery (P=0.002), duration of hospitalization (P<0.001), and the amount of blood loss (P=0.021) were lower in the native tissue repair group. Repair with transvaginal mesh was not associated with increased odds of major or minor adverse events (P>0.05 for all models examined). CONCLUSION: Perioperative and postoperative adverse events were comparable regardless of the operative approach.

Bicornuate uterus is an independent risk factor for cervical os insufficiency: A retrospective population based cohort study.

INTRODUCTION: The purpose of our study was to explore maternal and fetal outcomes in the second and third trimester in women with bicornuate uterus. METHODS: A total of 280,106 pregnancies met the inclusion criteria and were divided in two study groups: (1) pregnancies in women with bicornuate uterus (n = 444); and (2) controls (n = 279,662). The diagnosis of bicornuate uterus was performed in all patients during the workup for infertility or recurrent pregnancy loss, during pregnancy, or at the time of cesarean delivery. Multivariate logistic regression models were performed in order to assess the risk factors for cervical insufficiency in women with bicornuate uterus. RESULTS: The rate of women with a bicornuate uterus in our population was 0.15%. Women with bicornuate uterus had lower parity (2.93 ± 1.90 vs. 3.42 ± 2.51, p < 0.001) and a higher rate of previous cesarean deliveries (54.1% vs. 12.3%, p < 0.001). In addition, these patients were more prone to conceive with assisted reproductive techniques (5.6% vs. 1.9%, p < 0.001) and had a significantly higher rate of recurrent abortions (12.4% vs. 5.1%, p < 0.001) compared to controls. CONCLUSIONS: Bicornuate uterus is an independent risk factor for cervical os insufficiency. This is an important finding due to the burden of the risk for midtrimester periviable birth associated with cervical incompetence.

Long-term outcome (5-10 years) after non absorbable mesh insertion compared to partially absorbable mesh insertion for anterior vaginal wall prolapse repair
