Perinatal outcome of twin-to-twin transfusion syndrome complicated with incidental septostomy after laser photocoagulation: A systematic review and meta-analysis.

AIM: To evaluate perinatal outcomes of incidental septostomy (IS) after laser photocoagulation for twin-to-twin transfusion syndrome (TTTS), and to compare the outcomes with those who had intact intertwin membrane. METHODS: Databases such as PubMed, Web of Science, Scopus, and Embase were systematically searched from inception up to August 2020. The random-effects model was used to pool the mean difference (MD) or odds-ratio (OR) with the corresponding 95% confidence intervals (CIs). Primary outcome was incidence of preterm delivery, and preterm premature rupture of membranes (PPROM), while secondary outcomes included gestational age (GA) at intervention, GA at delivery, neonatal survival, and incidence of pseudoamniotic band syndrome (PABS). RESULTS: Four studies (1442 patients) met our inclusion criteria. Postoperative identification of IS was associated with earlier GA at delivery (MD = -2.52; 95% CI: -3.22, -1.82; p < 0.00), higher risk of PPROM < 32 weeks (OR = 2.82; 95% CI: 1.80, 4.40; p < 0.001), and preterm delivery < 32 weeks (OR = 4.01; 95% CI: 1.27, 12.63; p = 0.02). No differences were noted in pseudoamniotic band syndrome, at least one or dual neonatal survival rate between IS and non-IS groups. CONCLUSIONS: Occurrence of IS after laser photocoagulation for TTTS is associated with earlier GA at delivery, increased risk for PPROM and preterm delivery <32 weeks' gestation. However, neonatal survival does not appear to be affected by this complication.

Sentinel Lymph Nodes and Precision Surgery in Gynecologic Cancer.

Besides histologic features, the presence of nodal metastasis is the most crucial prognostic factor for recurrence and survival for patients with gynecologic cancer. Conventionally, lymphadenectomy has been performed routinely to assess lymphatic metastasis. However, lymphadenectomy may be unnecessary in early-stage gynecologic cancer, because the percentage of patients with lymph node involvement is very low. The recent use of sentinel lymph node mapping has provided high feasibility, safety, and accuracy in the assessment of nodal metastasis. The National Comprehensive Cancer Network Clinical Practice Guidelines have incorporated the sentinel lymph node for nodal evaluation in vulvar, endometrial, and cervical cancers.

Vasa previa: a multicenter retrospective cohort study.

OBJECTIVE: The objective of the study was to describe the characteristics and outcomes of patients with antenatal diagnosis of vasa previa and evaluate the predictive factors of resolution in a contemporary large, multicenter data set. STUDY DESIGN: This was a retrospective multicenter cohort study of all antenatally diagnosed cases of vasa previa, identified via ultrasound and electronic medical record, between January 2011 and July 2018 in 5 US centers. Records were abstracted to obtain variables at diagnosis, throughout pregnancy, and outcomes, including maternal and neonatal variables. Data were reported as median [range] or n (percentage). Descriptive statistics, receiver-operating characteristics, and logistic regression analysis were used as appropriate. RESULTS: One hundred thirty-six cases of vasa previa were identified in 5 centers during the study period, 19 (14%) of which resolved spontaneously at median estimated gestational age of 27 weeks [19-34]. All subjects with unresolved vasa previa underwent cesarean delivery at a median estimated gestational age of 34 weeks [27-39] with the median estimated blood loss of 800 mL [250-2000]. Rates for vaginal bleeding, preterm labor, premature rupture of membrane, and need for blood product transfusion were not different between the resolved and unresolved group (P = NS). The odds ratio for resolution in those with the estimated gestational age of less than 24 weeks at the time of diagnosis was 7.9 (95% confidence interval, 2.1-29.4) after adjustment for confounding variables. CONCLUSION: Our data suggest that outcomes in antenatally diagnosed cases of vasa previa are excellent. Furthermore, our data report a higher chance of resolution when the condition is diagnosed before 24 weeks of gestation.

Partial tubal devascularisation: a novel procedure for tubal conservation in ectopic pregnancy.

Ectopic pregnancy is a serious condition that complicates 1-2% of pregnancies. Using surgical management is efficient, but may have an impact on future fertility. Although conservative tubal surgery has not been shown to have a significant advantage over a salpingectomy in terms of the future fertility potential, the conservative surgical techniques remain widely-utilised, particularly in the context of a contralateral diseased or absent tube. We hereby report a case series of a novel procedure to conserve the fallopian tube with the minimal risk of an incisional site bleeding through a partial segmental devascularisation. This technique seems to be an efficient method to minimise the intraoperative bleeding, limit the need for a blood transfusion, and yields a higher success rate of the procedure without jeopardising the blood supply and vitality of the tubes. Impact Statement What is already known on this subject? Conservative surgery has a significant value in women with a contralateral absent or diseased tube. However, a conservative management could be challenging due to the significant bleeding which can be encountered during the surgery. What the results of this study add? The partial devascularisation technique could achieve an adequate haemostasis by blocking the ascending blood supply only to the affected segment of the fallopian tube. What the implications are of these findings for clinical practice and/or further research? A partial devascularisation is a successful conservative surgical treatment option in most patients when the procedure is indicated.

Management of Spontaneous Labor in Primigravidae: Labor Scale versus WHO Partograph (SLiP Trial) Randomized Controlled Trial.

OBJECTIVE: We aimed to compare maternal and neonatal outcomes of spontaneous term labor among primigravidae who were monitored by the novel labor scale versus the World Health Organization (WHO) partograph. STUDY DESIGN: A single center, double-blinded randomized trial had been conducted between July 2015 and June 2016. Nulliparous women in spontaneous labor with singleton term pregnancies were randomized to either labor scale or the WHO partograph for management of labor. Primary outcome was successful vaginal delivery. Secondary outcome included low APGAR scores, birth injuries, postpartum hemorrhage, and infection. RESULTS: One hundred ten patients were randomized (55 in each arm). Women managed with labor scale had significantly lower rate of cesarean deliveries than women managed with the partograph arm (3.6% versus 18.2%, P=0.03). There was a significant reduction in the rate and duration of oxytocin administration for augmentation of labor (21.8% versus 69.1%, P < 0.0001) and a significant increase in average 1-minute APGAR score in the labor scale group. CONCLUSION: Labor monitoring with the labor scale is associated with lower rate of cesarean section, less and shorter use of oxytocin for augmentation of labor. Monitoring of labor progress starting at 5 cm or more is also associated with lower rate of cesarean delivery.

Prenatal management of fetal intrapericardial teratoma: a systematic review.

OBJECTIVES: The purpose of this systematic review is to provide a comprehensive overview on the clinical course, perinatal outcome, and effectiveness of prenatal management options for pericardial teratoma. METHODS: A comprehensive search including Ovid MEDLINE, Ovid EMBASE, and Scopus was conducted from inception to September 2016. All studies that reported the prenatal course of pericardial teratoma in singleton or twin gestations were considered eligible. Standardized forms were used for data abstraction by two independent reviewers. RESULTS: Out of 217 screened abstracts, 59 studies reporting 67 fetuses with pericardial teratoma were included. Twenty-three singleton fetuses and 3 fetuses in twin gestations underwent prenatal treatment, and 20 (76.9%) of them were hydropic at the time of intervention. Of those, 15/20 (75%) had a favorable outcome. In the non-intervention group (n = 41), 26 (63.4%) developed hydrops, and out of those, 8 (30.8%) had a favorable outcome. CONCLUSION: Prenatal fluid drainage and other prenatal techniques have been utilized in the treatment of intrapericardial teratoma. While most fetuses tolerated pericardiocentesis, the neonatal benefit of this procedure is still uncertain, and outcomes of other interventions had variable success. Prenatal intervention for pericardial teratoma may be an option in specialized units but, given the maternal and fetal risks, needs careful consideration. © 2017 John Wiley & Sons, Ltd.

Loop Electrosurgical Excision Procedure Instead of Cold-Knife Conization for Cervical Intraepithelial Neoplasia in Women With Unsatisfactory Colposcopic Examinations: A Systematic Review and Meta-Analysis.

OBJECTIVES: This meta-analysis compared loop electrosurgical excision procedure (LEEP) with cold-knife conization (CKC) for treating cervical intraepithelial neoplasia (CIN) in patients with unsatisfactory colposcopic examinations. MATERIAL AND METHODS: A literature search on MEDLINE, EMBASE, Cochrane Systematic Reviews, CENTRAL, Web of Science, and Scopus databases was conducted from inception until April 2015. We included clinical trials and cohort studies comparing CKC with LEEP for treating CIN. The primary outcome was a combined end point of persistent CIN (<6 months after conization) and recurrent CIN (>6 months). Secondary outcomes included procedural, pathologic, and long-term outcomes. Pooled relative risk (RR) and weighted mean difference (WMD) were used to report binary and continuous outcomes, respectively. RESULTS: Among 26 studies, the incidence of persistent and recurrent disease after LEEP was comparable with that after CKC (15.6% vs 7.38%; RR = 1.35; 95% CI = 1.00-1.81). Loop electrosurgical excision procedure was faster, caused less intraoperative bleeding, and resulted in shorter hospital stay (WMD, 9.5 minutes [95% CI = 6.4-12.6 minutes]; WMD, 42.4 mL [95% CI = 21.3-106 mL]; and WMD, 1.5 days [95% CI = 1.1-1.8 days], respectively). Loop electrosurgical excision procedure cones were shallower with overall less volume and weight than CKC (WMD, 5.1 mm [95% CI = 3.2-7.1 mm]; 2.6 mm [95% CI = 0.6-5.7 mm]; and 2.6 g [95% CI = 1.4-3.7 g], respectively). During follow-up, LEEP was associated with less cervical stenosis and fewer unsatisfactory examinations; however, this was not statistically significant (RR, 0.5 [95% CI = 0.1-1.5]; RR, 0.7 [95% CI = 0.4-1.2], respectively). CONCLUSIONS: Loop electrosurgical excision procedure is an acceptable alternative to CKC in women with CIN and unsatisfactory colposcopic examinations. Close follow-up is necessary for prompt detection and treatment of persistent or recurrent disease.

Staging for low malignant potential ovarian tumors: a global perspective.

OBJECTIVE: We describe current evidence for staging low malignant potential ovarian tumors and their conformity to current consensus guidelines and practice from an international perspective. DATA SOURCES: A search of MEDLINE, EMBASE, and SCOPUS databases was conducted for articles published between January 1990 and April 2015. STUDY ELIGIBILITY CRITERIA: Studies on low malignant potential ovarian tumors that evaluated the prognostic value of disease stage, staging vs no staging, complete vs incomplete staging, or discrete components of staging were eligible. Studies that described only crude survival rates were excluded. STUDY APPRAISAL AND SYNTHESIS METHODS: Eligible studies were categorized according to their outcome (disease stage, staging procedure, or discrete staging elements). Data were abstracted using a standard form. Inconsistencies on data abstraction were resolved by consensus among the authors. Risk of bias was assessed using the Newcastle-Ottawa Scale. RESULTS: Of 1116 studies, 702 were excluded for irrelevance and 364 for not meeting inclusion criteria. Nine studies were excluded for describing crude survival rates without a comparative conclusion. We found that studies supporting the value of defining disease stage or staging procedures (mostly conducted in northern Europe) included more patients than studies that did not find disease stage or staging useful (predominantly from North America, 4072 vs 3951). Disease stage correlated with survival in 13 of 25 studies, whereas none of the studies that evaluated the value of staging found it beneficial (9 studies, 1979 patients). Studies that evaluated isolated components of staging found no benefit to these procedures. Regional guidelines and consensus reviews drew conclusions based on a limited number of studies that generally originated from the same region. CONCLUSIONS: Although the correlation of stage with survival was mixed, performing staging procedures for low malignant potential ovarian tumors is not supported by the best available evidence. Guidelines in support of staging based their recommendations on a few regional studies and conflict with better-quality data that do not support staging procedures. An international consensus statement is needed to standardize the surgical management of low malignant potential ovarian tumors.

Intraoperative Predictors of Long-term Outcomes After Radiofrequency Endometrial Ablation.

STUDY OBJECTIVE: To identify intraoperative predictors of radiofrequency ablation (RFA) failure after adjusting for clinical risk factors. DESIGN: A cohort study (Canadian Task Force II-2). SETTING: An academic institution in the Upper Midwest. PATIENTS: Data were retrospectively collected from medical records of women who underwent RFA and who had a postprocedure gynecologic assessment between April 1998 and December 2011. INTERVENTIONS: RFA. MEASUREMENTS AND MAIN RESULTS: The primary outcome was RFA failure, which was defined as hysterectomy, repeat ablation, synechiolysis, or treatment with gonadotropin-releasing hormone analogue for postablation pain or bleeding. Cox proportional hazards regression was used to test the predictability of intraoperative variables on RFA failure with adjustment for baseline predictors. We created an RFA index to capture the procedure duration divided by the uterine surface area. One thousand one hundred seventy-eight women were eligible. The median age at ablation was 44 years (interquartile range, 40-48 years), and the median parity was 2 (interquartile range, 2-3). Dysmenorrhea and prior tubal ligation were reported in 37.1% and 37.2% of women, respectively. After adjustment for baseline characteristics, intraoperative predictors of failure were uterine sounding length >10.5 cm (adjusted hazard ratio [HR] = 2.58; 95% confidence interval [CI], 1.31-5.05), uterine cavity length >6 cm (adjusted HR = 2.06; 95% CI, 1.30-3.27), uterine width >4.5 cm (adjusted HR = 2.06; 95% CI, 1.29-3.28), surface area >25 cm(2) (adjusted HR = 2.02; 95% CI, 1.26-3.23), procedure time <93 seconds (adjusted HR = 2.61; 95% CI, 1.25-5.47), and RFA index <3.6 (adjusted HR = 3.14; 95% CI, 1.70-5.77). CONCLUSION: Intraoperative parameters are predictive of long-term adverse outcomes of RFA independent of patient clinical characteristics. Uterine length, procedure duration, and RFA index are associated with unfavorable outcomes and thus could be used to optimize postprocedure patient counseling.

Hysteroscopic Morcellation Versus Resection for the Treatment of Uterine Cavitary Lesions: A Systematic Review and Meta-analysis.

This systematic review and meta-analysis compares hysteroscopic morcellation with electrosurgical resection to treat uterine cavitary lesions. A search of Ovid MEDLINE, Ovid Embase, Scopus, and Web of Science was conducted through August 18, 2015, for randomized controlled trials (RCTs) and prospective and retrospective studies, regardless of surgical indication and study language or sample size. Seven studies were eventually included (4 RCTs and 3 retrospective observational studies), enrolling 650 women. The meta-analysis showed that the total procedure time was significantly shorter for morcellation than for resection (weighted mean difference = 9.36 minutes; 95% confidence interval [CI], -15.08 to -3.64). When reviewing RCTs only, intrauterine morcellation was associated with a smaller fluid deficit and lower odds of incomplete lesion removal. This difference was not statistically significant in observational studies. There was no significant difference in the odds of surgical complications (odds ratio = 0.72; 95% CI, 0.20-2.57) or the number of insertions (weighted mean difference = -3.04; 95% CI, -7.86-1.78). In conclusion, compared with hysteroscopic resection, hysteroscopic morcellation is associated with a shorter operative time and possibly lower odds of incomplete lesion removal. The certainty in evidence was limited by heterogeneity and the small sample size.

Fetal cerebro-placental ratio and adverse perinatal outcome: systematic review and meta-analysis of the association and diagnostic performance.

OBJECTIVE: The objective of this meta-analysis is to assess the value of fetal cerebro-placental Doppler ratio (CPR) in predicting adverse perinatal outcome in pregnancies with fetal growth restriction (FGR). METHODS: Three databases were used: MEDLINE, EMBASE (with online Ovid interface) and SCOPUS and studies from inception to April 2015 were included. Studies that reported perinatal outcomes of fetuses at risk of FGR or sonographically diagnosed FGR that were evaluated with CPR were considered eligible. Perinatal outcomes include cesarean section (CS) for fetal distress, APGAR scores at 5 min, neonatal complications and admission to neonatal intensive care unit (NICU). Pooled data were expressed as odds ratio (OR) and confidence intervals (CI), and the summary receiver operating characteristic (SROC) curve was used to illustrate the diagnostic accuracy of CPR. RESULTS: Seven studies were eligible (1428 fetuses). Fetuses with abnormal CPR were at higher risk of CS for fetal distress (OR=4.49, 95% CI [1.63, 12.42]), lower APGAR scores (OR=4.01, 95% CI [2.65, 6.08]), admission to NICU (OR=9.65, 95% CI [3.02, 30.85]), and neonatal complications (OR=11.00, 95% [3.64, 15.37]) than fetuses who had normal CPR. These risks were higher among studies that included fetuses diagnosed with FGR than fetuses at risk of FGR. Abnormal CPR had higher diagnostic accuracy for adverse perinatal outcomes among "sonographically diagnosed FGR" studies than "at risk of FGR" studies. CONCLUSION: Abnormal CPR is associated with substantial risk of adverse perinatal outcomes. The test seems to be particularly useful for follow up of fetuses with sonographically diagnosed FGR.

Robotic radical hysterectomy in early stage cervical cancer: A systematic review and meta-analysis.

OBJECTIVE: To compare intraoperative and short-term postoperative outcomes of robotic radical hysterectomy (RRH) to laparoscopic and open approaches in the treatment of early stage cervical cancer. METHODS: A search of MEDLINE, EMBASE (using Ovid interface) and SCOPUS databases was conducted from database inception through February 15, 2014. We included studies comparing surgical approaches to radical hysterectomy (robotic vs. laparoscopic or abdominal, or both) in women with stages IA1-IIA cervical cancer. Intraoperative outcomes included estimated blood loss (EBL), operative time, number of pelvic lymph nodes harvested and intraoperative complications. Postoperative outcomes were hospital stay and surgical morbidity. The random effects model was used to pool weighted mean differences (WMDs) and odds ratios (OR). RESULTS: Twenty six nonrandomized studies were included (10 RRH vs abdominal radical hysterectomy [ARH], 9 RRH vs laparoscopic radical hysterectomy [LRH] and 7 compared all 3 approaches) enrolling 4013 women (1013 RRH, 710 LRH and 2290 ARH). RRH was associated with less EBL (WMD=384.3, 95% CI=233.7, 534.8) and shorter hospital stay (WMD=3.55, 95% CI=2.10, 5.00) than ARH. RRH was also associated with lower odds of febrile morbidity (OR=0.43, 95% CI=0.20-0.89), blood transfusion (OR=0.12, 95% CI 0.06, 0.25) and wound-related complications (OR=0.31, 95% CI=0.13, 0.73) vs. ARH. RRH was comparable to LRH in all intra- and postoperative outcomes. CONCLUSION: Current evidence suggests that RRH may be superior to ARH with lower EBL, shorter hospital stay, less febrile morbidity and wound-related complications. RRH and LRH appear equivalent in intraoperative and short-term postoperative outcomes and thus the choice of approach can be tailored to the choice of patient and surgeon.

Combined Endometrial Ablation and Levonorgestrel Intrauterine System Use in Women With Dysmenorrhea and Heavy Menstrual Bleeding: Novel Approach for Challenging Cases.

STUDY OBJECTIVE: To evaluate the feasibility and impact of levonorgestrel intrauterine system (LNG-IUS) on treatment failure after endometrial ablation (EA) in women with heavy menstrual bleeding (HMB) and dysmenorrhea at 4 years. DESIGN: Cohort study (Canadian Task Force II-2). SETTING: An academic institution in the upper Midwest. PATIENTS: All women with HMB and dysmenorrhea who underwent EA with combined placement of LNG-IUS (EA/LNG-IUS cohort, 23 women) after 2005 and an historic reference group from women who had EA alone (EA cohort, 65 women) from 1998 through the end of 2005. INTERVENTION: Radiofrequency EA, thermal balloon ablation, and LNG-IUS. MEASUREMENTS AND MAIN RESULTS: The primary outcome was treatment failure defined as persistent pain, bleeding, and hysterectomy after EA at 4 years. The combined treatment failure outcome was documented in 2 patients (8.7%) in the EA/LNG-IUS group and 19 patients (29.2%) in the EA group with an unadjusted OR of .23 (95% CI, .05-1.08). After adjusting for known risk factors of failure, the adjusted OR was .19 (95% CI, .26-.88). None of the women who underwent EA/LNG-IUS had hysterectomy for treatment failure compared with 16 (24%) in the EA group (p = .009); postablation pelvic pain was documented in 1 woman (4.3%) in the EA/LNG-IUS group compared with 8 women (12.3%) in the EA group (p = .24). One woman in the EA/LNG-IUS group (4.3%) presented with persistent bleeding compared with 15 (23.1%) in the EA group (p = .059). Office removal of the intrauterine device was performed in 4 women with no complications. CONCLUSION: LNG-IUS insertion at the time of EA is feasible and can provide added benefit after EA in women with dysmenorrhea and HMB.

The labour scale--assessment of the validity of a novel labour chart: a pilot study.

BACKGROUND: Labour dystocia is the most common indication for caesarean section (CS). This study assessed the validity of the labour scale (WHO partograph modification) as an intrapartum management tool to minimise over-diagnosis of labour dystocia. MATERIALS AND METHODS: The study included 77 women in the early active phase of labour using the scale. This scale covers the same titles as the partograph with the cervico-graph modified using National Institute of Clinical Excellence (NICE) recommendations that adjust interference according to clinical circumstances. Labour progress was plotted on the labour scale then on the partograph to compare outcomes. Maternal and fetal outcomes were compared with international and local reports. RESULTS: Only 21 (27.3%) women crossed the 'membrane line', which promotes amniotomy, and 35 women (45.5%) crossed the 'augmentation line' and received oxytocin. Four women were delivered by CS for failure to progress. When the same data were re-plotted on the partograph, twenty-eight women were diagnosed with failure to progress. The outcome difference between the 'labour scale' and the partograph was significant (P < 0.0001). Maternal and neonatal outcomes were excellent. CONCLUSIONS: We suggest that the 'labour scale' is a promising tool for labour management that minimises labour dystocia without additional maternal or fetal risk.

Abdominal disimpaction with lower uterine segment support as a novel technique to minimize fetal and maternal morbidities during cesarean section for obstructed labor: a case series.

Cesarean section for obstructed labor remains a difficult procedure that may be associated with serious fetal and maternal injuries. In this case series, we evaluated the use of abdominal disimpaction with lower segment support as a novel technique to minimize morbidities. Eight patients who underwent cesarean section for obstructed labor were recruited. Impacted fetal head was delivered using this technique and uterine extensions, bladder injury, vaginal injury, and intraoperative bleeding were reported. Maternal and neonatal outcomes were observed postoperatively. No major morbidities were reported. Accordingly, we consider this technique as a promising step to minimize complications during cesarean section for obstructed labor.

A novel technique for modified B-Lynch suture for the control of atonic postpartum haemorrhage.

The B-Lynch brace suture technique is a life-saving procedure. It is a simple and safe alternative to hysterectomy. Thus, it preserves fertility with less surgical morbidity. In this case series, we evaluated the use of a novel modification of the B-Lynch brace suture to minimise its potential reported complications. Five women with intractable primary atonic postpartum haemorrhage were reported. They were initially managed with bilateral uterine artery ligation. The procedure was resorted to women who did not respond to ligation. The procedure is efficient. Women were followed up for up to 24 months to report any complications.

Middle eastern college of obstetricians and gynecologists (MCOG) practice guidelines: Role of prediction models in management of trial of labor after cesarean section. Practice guideline no. 05-O-22✰,✰✰,☠,☠☠.

Cesarean delivery rates have been steadily rising since the beginning of the 21st century. The growing incidence is even more prominent in developing countries owing to lack of evidence-based guidance and audit, and the expansion of private practice. The uprise in Cesarean delivery rate has been associated with considerable financial burden and has increased the risk otherwise uncommon serious complications such as placenta accreta disorders and uterine rupture. In addition to primary prevention of Cesarean delivery, trial of labor after cesarean section is one of the most successful strategies to reduce Cesarean deliveries and minimize risks associated with higher order Cesarean deliveries. This guideline appraises patient selection strategies and use of prediction model to promote counseling and enhance safety in women considering vaginal birth after Cesarean.

Endometrial Cancer Individualized Scoring System (ECISS): A machine learning-based prediction model of endometrial cancer prognosis.

OBJECTIVE: To establish a prognostic model for endometrial cancer (EC) that individualizes a risk and management plan per patient and disease characteristics. METHODS: A multicenter retrospective study conducted in nine European gynecologic cancer centers. Women with confirmed EC between January 2008 to December 2015 were included. Demographics, disease characteristics, management, and follow-up information were collected. Cancer-specific survival (CSS) and disease-free survival (DFS) at 3 and 5 years comprise the primary outcomes of the study. Machine learning algorithms were applied to patient and disease characteristics. Model I: pretreatment model. Calculated probability was added to management variables (model II: treatment model), and the second calculated probability was added to perioperative and postoperative variables (model III). RESULTS: Of 1150 women, 1144 were eligible for 3-year survival analysis and 860 for 5-year survival analysis. Model I, II, and III accuracies of prediction of 5-year CSS were 84.88%/85.47% (in train and test sets), 85.47%/84.88%, and 87.35%/86.05%, respectively. Model I predicted 3-year CSS at an accuracy of 91.34%/87.02%. Accuracies of models I, II, and III in predicting 5-year DFS were 74.63%/76.72%, 77.03%/76.72%, and 80.61%/77.78%, respectively. CONCLUSION: The Endometrial Cancer Individualized Scoring System (ECISS) is a novel machine learning tool assessing patient-specific survival probability with high accuracy.

The use of multiple 8 compression suturing as a novel procedure to preserve fertility in patients with placenta accreta: case series.

Placenta accreta/percreta is a serious cause of intractable post-partum haemorrhage during caesarean section and a common cause of peripartum hysterectomy. In this case series, we evaluated the use of multiple 8 sutures as a novel procedure to preserve the uterus in these cases. Seven women with placenta accreta/percreta were initially managed with bilateral uterine artery ligation. The procedure was resorted to in cases that did not respond to ligation (five women). Women were followed up for up to 24 months to report complications.

Introduction to Machine Learning in Obstetrics and Gynecology.

In the digital age of the 21st century, we have witnessed an explosion in data matched by remarkable progress in the field of computer science and engineering, with the development of powerful and portable artificial intelligence-powered technologies. At the same time, global connectivity powered by mobile technology has led to an increasing number of connected users and connected devices. In just the past 5 years, the convergence of these technologies in obstetrics and gynecology has resulted in the development of innovative artificial intelligence-powered digital health devices that allow easy and accurate patient risk stratification for an array of conditions spanning early pregnancy, labor and delivery, and care of the newborn. Yet, breakthroughs in artificial intelligence and other new and emerging technologies currently have a slow adoption rate in medicine, despite the availability of large data sets that include individual electronic health records spanning years of care, genomics, and the microbiome. As a result, patient interactions with health care remain burdened by antiquated processes that are inefficient and inconvenient. A few health care institutions have recognized these gaps and, with an influx of venture capital investments, are now making in-roads in medical practice with digital products driven by artificial intelligence algorithms. In this article, we trace the history, applications, and ethical challenges of the artificial intelligence that will be at the forefront of digitally transforming obstetrics and gynecology and medical practice in general.
