Trial of labor versus elective cesarean delivery for patients with two prior cesarean sections: a systematic review and meta-analysis.

OBJECTIVE: Cesarean section (CS) rates have been on the rise globally, leading to an increasing number of women facing the decision between a Trial of Labor after two Cesarean Sections (TOLAC-2) or opting for an Elective Repeat Cesarean Section (ERCS). This study evaluates and compares safety outcomes of TOLAC and ERCS in women with a history of two previous CS deliveries. METHODS: PubMed, MEDLINE, EMbase, and Cochrane Central Register of Controlled Trials (CENTRAL) databases were searched for studies published until 30 June 2023. Eligible studies were included based on predetermined criteria, and a random-effects model was employed to pool data for maternal and neonatal outcomes. RESULTS: Thirteen studies with a combined sample size of 101,011 women who had two prior CS were included. TOLAC-2 was associated with significantly higher maternal mortality (odds ratio (OR)=1.50, 95% confidence interval (CI)= 1.25-1.81) and higher chance of uterine rupture (OR = 7.15, 95% CI = 3.44-14.87) compared to ERCS. However, no correlation was found for other maternal outcomes, including blood transfusion, hysterectomy, or post-partum hemorrhage. Furthermore, neonatal outcomes, such as Apgar scores, NICU admissions, and neonatal mortality, were comparable in the TOLAC-2 and ERCS groups. CONCLUSION: Our findings suggest an increased risk of uterine rupture and maternal mortality with TOLAC-2, emphasizing the need for personalized risk assessment and shared decision-making by healthcare professionals. Additional studies are needed to refine our understanding of these outcomes in the context of TOLAC-2.

Prediction of intraperitoneal adhesions in repeated cesarean sections: A Systematic review and Meta-analysis.

OBJECTIVE: With the rate of repeated cesarean sections on the rise, intraperitoneal adhesions caused by repeated cesareans could give rise to maternal morbidity during delivery. As a result, it's critical to have the ability to predict adhesions. The current meta-analysis aims to determine if intraperitoneal adhesions are likely to be present based on the characteristics of the cesarean scar, striae gravidarum, and sliding sign. MATERIALS AND METHODS: We systematically searched electronicdatabases beforeretrieving articles up until October 13th, 2022 for analysis. After data extraction and literature screening, we first performed a quality assessment using the QUADAS-2 score system. Following that, a bivariate random-effect meta-analysis model was used to obtain the combined diagnostic and predictive values. To pinpoint the origins of heterogeneity, we conducted a subgroup analysis. Fagan's Nomogram was used to validate the clinical utility. Sensitivity analysis was used to gauge the reliability of each included study, and Egger's test and funnel plot asymmetry was used to investigate publication bias. RESULTS: 25 studies totaling 1840 patients with intra-abdominal adhesions and 2501 controls without adhesions were included in the systematic review. Diagnostic values from 8 studies regarding skin characteristics were combined, and the results for depressed scar showed: sensitivity[95 %CI] = 0.38[0.34-0.42]; Specificity[95 %CI] = 0.88[0.85-0.90]; DOR[95 %CI] = 4.78[2.50-9.13]; AUC = 0.65. Negative sliding sign from 7 studies, although not showing a diagnostic difference between cases and controls, had excellent predictive values: sensitivity[95 %CI] = 0.71[0.65-0.77]; Specificity[95 %CI] = 0.87[0.85-0.89]; DOR[95 %CI] = 6.88[0.6-78.9]; AUC = 0.77. Subgroup analysis illustrated non-Turkish studies to reveal more significant associations than Turkish studies. CONCLUSION: Our meta-analysis found that the occurrence of adhesions can be predicted by the characteristics of abdominal wounds, particularly depressed scar, and scar width,as well as a negative sliding sign following a previous cesarean section.

The impact of extending the second stage of labor on repeat cesarean section and maternal and neonatal outcome.

OBJECTIVE: To evaluate the effects of extending the second stage of labor in women attempting a trial of labor after a cesarean section (TOLAC). METHOD: A retrospective cohort study comparing maternal and neonatal outcomes following TOLAC over two periods: period I whose prolonged second stage was considered 2 h, and period II whose prolonged second stage was considered 3 h. The primary outcome was repeat cesarean delivery (CD) rate. RESULTS: Incidence of repeat CD was significantly lower in period II (18.1% vs 29.7%, P < 0.001). Incidence of uterine rupture was significantly higher in period II (P < 0.001). Instrumental delivery rates were significantly higher in period II (26.2% vs 15.6%, odds ratio [OR] 1.67, 95% CI 1.21-3.56, P < 0.001). Rates of third- and fourth-degree perineal lacerations, chorioamnionitis, and length of hospital stay were similar between groups. Incidence of fetal acidemia was significantly higher in period II (1.5% vs 0.7%, OR 2.14, 95% CI 1.32-5.63, P < 0.001), and incidence of neonatal intensive care unit (NICU) admission was significantly higher (2.5% vs 1.6%, P = 0.004). CONCLUSION: Extension of the second stage of labor is associated with a decrease in repeat CD rate with a concomitant increase in instrumental delivery rates, uterine rupture, fetal acidemia, and NICU admissions. These findings may warrant further consideration of allowing a prolonged second stage in patients attempting TOLAC.

Delivery after a previous cesarean section reviewed.

At the start of the 20th century, cesarean section (CS) was uncommon in obstetrics. By the end of the century, CS rates had increased dramatically worldwide. Although the explanation for the increase is multifactorial, a major driver in the ongoing escalation is the increase in women who are delivered by repeat CS. This is due, in part, to the fact that there has been a sharp fall in vaginal birth after CS (VBAC) rates as fewer women are offered a trial of labor after CS (TOLAC), due principally to fears of a catastrophic intrapartum uterine rupture. This paper reviewed international VBAC policies and trends. A number of themes emerged. The risk of intrapartum rupture and its associated complications is low and may sometimes be overestimated. Individual maternity hospitals in both developed and developing countries are inadequately resourced to safely supervise a TOLAC. Efforts to mitigate the risks of TOLAC by careful patient selection and good clinical practices may be underutilized. Given the serious short-term and long-term consequences of rising CS rates for women and for maternity services generally, a review of TOLAC policies worldwide should be prioritized and consideration given to convening a Global Consensus Development Conference on Delivery after CS.

The safety of trial of labor after cesarean section (TOLAC) versus elective repeat cesarean section (ERCS): a systematic review and meta-analysis.

OBJECTIVE: Women's choice of birth following a cesarean delivery either includes a trial of elective repeat cesarean section (ERCS) or a trial of labor after cesarean (TOLAC). No comprehensive overview or systematic summary is currently available. METHODS: EMBASE, PubMed, and the Cochrane Library databases were searched from inception to 1 February 2020. Studies reporting the safety of TOLAC and ERCS in pregnant women with prior cesarean delivery were included. Statistical analysis was performed using RevMan 5.3 and Stata 15.0. Odds ratios (ORs) and 95% confidence intervals (CIs) were adopted as the effective measures. RESULTS: A total of 13 studies covering 676,532 cases were included in this meta-analysis. The results demonstrated that the rates of uterine rupture (OR = 3.35, 95%CI [1.57, 7.15], I2 = 81%), neonatal asphyxia (OR = 2.32, 95%CI [1.76, 3.08], I2 = 0%) and perinatal death (OR = 1.71, 95%CI [1.29, 2.25], I2 = 0%) were higher in the TOLAC group compared with the ERCS group. The rates of peripartum hysterectomy (OR = 0.70, 95%CI [0.44, 1.11], I2 = 62%), blood transfusion (OR = 1.24, 95%CI [0.72, 2.12], I2 = 95%), and puerperal infection (OR = 1.11, 95%CI [0.77, 1.60], I2 = 95%) showed no significant differences between the two groups. CONCLUSION: TOLAC is associated with a higher risk of uterine rupture, neonatal asphyxia, and perinatal death compared with ERCS. Nevertheless, it should be noted that the risks of all complications were small in both groups. This information is important for healthcare providers and women choosing the delivery type.

Preoperative sonographic sliding sign for prediction of intra-abdominal adhesions before repeat cesarean delivery.

OBJECTIVE: To evaluate the usefulness of the uterine sliding sign for predicting intra-abdominal adhesions in women undergoing repeat cesarean section (CS) and the association of the sliding sign with other operative and neonatal outcomes. METHODS: A prospective cohort study was conducted among pregnant women with at least one previous CS. Transabdominal ultrasonography was performed and classified as a positive or negative sliding sign. Surgeons blinded to the sonographic results assessed intra-abdominal adhesions. The sensitivity, specificity, positive predictive value, and negative predictive value were calculated. Operative and neonatal outcomes of the positive and negative sliding sign groups were compared. Factors associated with intraoperative adhesions were also analyzed. RESULTS: A total of 380 women were recruited. The sensitivity and specificity of the uterine sliding sign to detect moderate-to-thick adhesions were 60.6% and 91.9%, respectively. A negative sliding sign was significantly associated with a higher incidence of adhesions, longer skin-to-delivery time, longer total operative time, and lower 5-min APGAR score in newborns. A negative sliding sign and history of two or more previous CS were significant predictors of moderate-to-thick adhesions. CONCLUSION: The uterine sliding sign is an independent predictor of intraoperative adhesions, with acceptable sensitivity and high specificity and negative predictive value.

The use of ultrasound sliding sign for prediction of adhesions in women undergoing repeated caesarean section.

We carried out this study to validate the use of ultrasound sliding sign to predict intraperitoneal adhesions in women undergoing repeated caesarean section (CS). A cross-section study was performed in women with at least one CS scheduled for an elective CS. We used the sliding sign of the uterus against the anterior abdominal wall to assess intraperitoneal adhesions, positive sliding sign if uterus moved freely and a negative sliding sign if limited mobility. The obstetrician was blind to the ultrasound results, asked to report if adhesions were absent or present during CS to validate accuracy of the sliding sign. We examined 120 women, negative sliding was reported in 54 patients, positive sliding in 66 women. The presence of intra-abdominal adhesions was confirmed in 44/54 cases assigned to the high-risk group, while the prediction of low risk for adhesions confirmed in 66/66 patients with a sensitivity of 100%, specificity of 86.84%. Sliding sign is an effective method to detect intra-abdominal adhesions in women with a history of repeated caesarean delivery.Impact statementWhat is already known on this subject? There has been a dramatic increase in the caesarean section (CS) rate worldwide; repeated CSs may be associated with intraperitoneal adhesions that result in difficulty during the procedure and may be related to bowel or bladder injuries and neonatal morbidities.What do the results of this study add? The sliding sign by ultrasound has a sensitivity of 100%, specificity of 86.84%, a positive predictive value of 81.5, a negative predictive value of 100, and accuracy of 91.67, considering it rapid, easy and reliable method for prediction of intraperitoneal adhesions.What are the implications of these findings for clinical practice and/or future research? The use of sliding sign by ultrasound in cases with repeated CSs offers a good predictor tool for presence of intraperitoneal adhesions and subsequently avoid severe sequels during surgery and good preparation.

Complete Cervicouterine Dissociation After Repeat Cesarean Sections: A Case Report.

INTRODUCTION: The number of cesarean deliveries (CDs) has extremely increased in the last decades. Although it is a common and relatively safe surgical procedure, there are several potential complications. To the best of our knowledge, complete cervicouterine dissociation after several CDs has not been reported before in the medical literature. CASE REPORT: A 28-year-old woman with a history of 6 CDs presented with abdominal pain and vaginal bleeding. The patient's most recent CD happened three weeks before the current presentation. Transabdominal ultrasonography examination and magnetic resonance imaging revealed the absence of continuity with the uterine cervix and corpus with associated pelvic hematoma. Laparotomy findings confirmed the imaging findings, and the displaced uterine corpus was removed with the evacuation of the associating pelvic hematoma. CONCLUSION: Uterine dehiscence and rupture are among the relatively common complications of CD. Uterine rupture and dehiscence are focal disorders, and complete cervicouterine dissociation has not been seen before. Multiple CDs are among the risk factors for complete cervicouterine dissociation, and abnormal uterine bleeding is the most common symptom. Imaging findings allow a quick and definitive diagnosis, and surgical intervention may be planned accordingly based on the imaging findings.

Trial of labor after cesarean delivery for estimated large for gestational age fetuses: A retrospective cohort study.

OBJECTIVE: Although ultrasonographic estimation of fetal weight ≥90th percentile is not associated with a greater risk for uterine rupture, trial of labor after cesarean delivery (TOLAC) is considered relatively contraindicated for macrosomic fetuses. Hence, when an estimated fetal weight of 4000 g is detected, TOLAC is usually avoided.Our aim was to evaluate the obstetrical outcome and safety of TOLAC in women with estimated large for gestational age fetuses (eLGA) (≥90th percentile). STUDY DESIGN: Our retrospective cohort study encompassed all pregnant women with an estimated fetal weight ≥90th percentile for gestational age, admitted to a single tertiary care center between January 2012-July 2017 for TOLAC. RESULTS: 1949 women met the inclusion criteria; 78 (4%) eLGA and 1871 (96%) controls. Fifty-five (70.5%) women in the study group had experienced a successful vaginal delivery compared to 1506 (80.5%) of the controls (p = 0.03). The rate of obstetrical complications, including scar dehiscence, uterine rupture, a 3rd/4th degree perineal tear or shoulder dystocia were comparable. The rate of post-partum hemorrhage (PPH) increased in the study group compared to the controls (7.7 % vs.1.7%; p = 0.001). CONCLUSION: TOLAC for eLGA fetuses can be considered safe, however, lower successful rates of vaginal births after a cesarean delivery and an increased PPH rate, may be expected.

Outcomes and risk factors for failed trial of labor after cesarean delivery (TOLAC) in women with one previous cesarean section: a Chinese population-based study.

OBJECTIVE: To evaluate the outcomes and risk factors for trial of labor after cesarean delivery (TOLAC) failure in patients in China. METHODS: Consecutive patients who had a previous cesarean delivery (CD) and attempted TOLAC were included from 2014 to 2020. Patients who successfully delivered were classified into the TOLAC success group. Patients who attempted TOLAC but had a repeat CD due to medical issues were classified into the TOLAC failure group. Multiple logistic regression analyses were performed to examine the risk factors for TOLAC failure. RESULTS: In total, 720 women who had a previous CD and attempted TOLAC were identified and included. The success rate of TOLAC was 84.2%(606/720). Seven patients were diagnosed with uterine rupture, none of whom underwent hysterectomy. Multiple logistic regression analysis showed that the induction of labor (OR = 2.843, 95% CI: 1.571-5.145, P < 0.001) was positively associated with TOLAC failure, but the thickness of the lower uterine segment (LUS) (OR = 0.215, 95% CI: 0.103-0.448, P < 0.001) was negatively associated with TOLAC failure. CONCLUSIONS: This study suggested that TOLAC was effective in decreasing CD rates in the Chinese population. The induction of labor was positively associated with TOLAC failure, but the thickness of the LUS was negatively associated with TOLAC failure. Our findings need to be confirmed in larger samples with patients of different ethnicities.

Intra-abdominal Adhesions among Patients Undergoing Repeat Caesarean Section in Department of Obstetrics and Gynaecology of a Tertiary Care Centre: A Descriptive Cross-sectional Study.

Introduction: Adhesions are one of the common complications encountered after caesarean section whose risk increases with the number of caesarean deliveries. This study aimed to find out the prevalence of intra-abdominal adhesions among patients undergoing repeat caesarean section in a tertiary care centre. Methods: A descriptive cross-sectional study was conducted on 74 pregnant women undergoing repeat caesarean section in the Department of Obstetrics and Gynaecology of a tertiary care centre from July, 2021 to December, 2021 after receiving the ethical approval from the Institutional Review Committee (Reference number: 2107202103). Pregnant women who met the eligibility criteria were included in the study. Convenience sampling was done. The severity of the adhesions was classified using the Tulandi and Lyell classification. Data were analysed using the Statistical Package for the Social Sciences version 26.0 software. Point estimate at 90% Confidence Interval was calculated along with frequency and percentage for binary data along with mean and standard deviation for continuous data. Results: Out of 74 women undergoing repeat caesarean section, 55 (74.32%) (65.99-82.65 at 90% Confidence Interval) had developed intra-abdominal adhesions. Conclusions: Our study showed that the prevalence of intra-abdominal adhesions among patients undergoing repeat caesarean section was higher when compared to similar studies conducted in similar settings. Keywords: postoperative complications; repeat caesarean section; surgical adhesions.

Risk factors and outcomes associated with type of uterine rupture.

PURPOSE: To identify risk factors associated with the occurrence of complete uterine rupture (CUR) in comparison to partial uterine rupture (PUR) to further investigate to what extent a standardized definition is needed and what clinical implications can be drawn. METHODS: Between 2005 and 2017 cases with CUR and PUR at Charité University Berlin, Germany were retrospectively identified. Demographic, obstetric and outcome variables were analyzed regarding the type of rupture. Binary multivariate regression analysis was conducted to identify risk factors associated with CUR. In addition, the intended route of delivery (trial of labor after cesarean delivery (TOLAC) and elective repeat cesarean delivery (ERCD)), divided according to the type of rupture, was compared. RESULTS: 92 cases with uterine rupture were identified out of a total of 64.063 births (0.14%). Puerperal complications were more frequent in CUR (67.9 versus 41.1%, p = 0.021). Multiparity ≥ 3 was more frequent in CUR (31 versus 10.7%, p = 0.020). Factors increasing the risk for CUR were parity ≥ 3 (OR = 3.8, p = 0.025), previous vaginal birth (OR = 4.4, p = 0.011), TOLAC (OR = 6.5, p < 0.001) and the use of oxytocin (OR = 2.9, p = 0.036). After multivariate analysis, the only independent risk factor associated with CUR was TOLAC (OR = 7.4, p = 0.017). CONCLUSION: TOLAC is the only independent risk factor for CUR. After optimized antenatal counselling TOLAC and ERCD had comparable short-term maternal and fetal outcomes in a high resource setting. A high number of previous vaginal births does not eliminate the risk of uterine rupture. A clear distinction between CUR and PUR is essential to ensure comparability among studies.

Neonatal outcomes in trial of vaginal birth versus repeat caesarean delivery in preterm pregnancies: A prospective cohort study.

OBJECTIVE: To characterise neonatal morbidity following preterm trial of labour (TOL) in comparison with elective repeat caesarean section (eRCS) specifically among patients without a previous vaginal delivery who may have a lower success rate of vaginal birth after caesarean. DESIGN: This is a secondary analysis of a multicentre prospective database. SETTING/POPULATION: Maternal and Fetal Medicine Unit Cesarean Section Registry. POPULATION: Singleton pregnancies in women without a previous vaginal delivery who delivered at 24+0  weeks to 36+6  weeks gestation. METHODS: Neonatal outcomes were compared between those with a TOL and those undergoing eRCS. Logistic regression was used to control for confounders, including gestational age at delivery. MAIN OUTCOME MEASURES: Composite neonatal morbidity. RESULTS: A total of 1906 patients were included, 985 with TOL and 921 with no TOL. The TOL success rate was 63.1%. The rate of uterine rupture was low, at 0.10% in the TOL group and 0.11% in the eRCS group (p = 0.32). After adjustment, neonates born to women undergoing a TOL had no statistically significant difference in outcomes including composite neonatal outcome (adjusted odds ratio 0.86, 95% CI 0.68-1.09), neonatal intensive care unit admission, respiratory distress syndrome, necrotising enterocolitis, hypoxic ischaemic encephalopathy, seizures, transient tachypnoea of the newborn, compared with patients who underwent eRCS, with the exception of decreased risk of proven/suspected sepsis (adjusted odds ratio 0.68, 95% CI 0.52-0.87) CONCLUSION: A TOL in preterm patients without a previous vaginal delivery was not found to have a statistically significant association with increased neonatal morbidity.

Recurrent uterine rupture in third trimester of pregnancy.

We report a case of recurrent upper segment uterine rupture in a 31-year-old woman at 32+5/40 weeks of gestation. She had fundal uterine rupture 3 years ago in her first pregnancy at 40 weeks of gestation. There was no history of uterine malformation or prior uterine surgery. However, we noted that she had had three laparoscopic procedures for endometriosis treatment. She was scheduled to have an elective repeat caesarean section at 34+6/40 weeks of gestation in the index pregnancy. Unfortunately, she presented at 32+5/40 weeks with features of acute abdomen and signs of fetal distress. She had a category 1 caesarean section and was found to have fundal uterine rupture at the same site. She had a smooth uneventful recovery following a timely intervention and discharged home on day 5 postoperatively in a good condition with her baby girl.

Planned mode of birth after previous caesarean section and special educational needs in childhood: a population-based record linkage cohort study.

OBJECTIVE: To investigate the association between planned mode of birth after previous caesarean section and a child's risk of having a record of special educational needs (SENs). DESIGN: Population-based cohort study. SETTING: Scotland. POPULATION: A cohort of 44 892 singleton children born at term in Scotland between 2002 and 2011 to women with one or more previous caesarean sections. METHODS: Linkage of Scottish national health and education data sets. MAIN OUTCOME MEASURES: Any SENs and specific types of SEN recorded when a child was aged 4-11 years and attending a Scottish primary or special school. RESULTS: Children born following planned vaginal birth after previous caesarean (VBAC) compared with elective repeat caesarean section (ERCS) had a similar risk of having a record of any SENs (19.24 versus 17.63%, adjusted risk ratio aRR 1.04, 95% CI 0.99-1.09) or specific types of SEN. There was also little evidence that planned VBAC with or without labour induction compared with ERCS was associated with a child's risk of having a record of any SENs (21.42 versus 17.63%, aRR 1.09, 95% CI 1.01-1.17 and 18.78 versus 17.63%, aRR 1.03, 95% CI 0.98-1.08, respectively) or most types of SEN. However, an increased risk of sensory impairment was seen for planned VBAC with labour induction compared with ERCS (1.18 versus 0.78%, risk difference 0.4%, adjusted odds ratio aOR 1.60, 95% CI 1.09-2.34). CONCLUSIONS: This study provides little evidence of an association between planned mode of birth after previous caesarean and SENs in childhood beyond a small absolute increased risk of sensory impairment seen for planned VBAC with labour induction. This finding may be the result of performing multiple comparisons or residual confounding. The findings provide valuable information to manage and counsel women with previous caesarean section concerning their future birth choices. TWEETABLE ABSTRACT: There is little evidence planned mode of birth after previous caesarean section is associated with special educational needs in childhood.

Prediction of intraperitoneal adhesions using striae gravidarum and scar characteristics in women undergoing repeated cesarean sections.

BACKGROUND: The current fact of increasing rates of cesarean deliveries is a catastrophe. Recurrent cesareans result in intraperitoneal adhesions that would lead to maternal morbidity during delivery. Great efforts are directed towards the prediction of intraperitoneal adhesions to provide the best care for laboring women. The aim of the current study was to evaluate the role of abdominal striae and cesarean scar characters in the prediction of intraperitoneal adhesions. METHODS: This was a case- control study conducted in the emergency ward of the obstetrics and gynecology department of a tertiary hospital from June to December 2019. The study was carried on patients admitted to the ward fulfilling particular inclusion and exclusion criteria. The study included two groups, group one was assessed for the presence of striae, and the degree of intraperitoneal adhesions was evaluated during the current cesarean section. Group two included patients without evidence of abdominal striae. They were evaluated for the severity of adhesions also after evaluation of the previous scar. Evaluation of the striae was done using Davey's scoring system. The scar was assessed using the Vancouver Scar Scale. The modified Nair's scoring system was used to evaluate intraperitoneal adhesions. RESULTS: The study group included 203 women, while the control group included 205 women. There were significant differences in the demographic characters of the recruited patients (p-value 0.001 for almost all variables). The mean Davey score in those with mild, moderate, and severe striae was 1.82 ± 0.39, 3.57 ± 0.5, and 6.73 ± 0.94, respectively (p-value < 0.001). Higher scores for the parameters of the Vancouver scale were present in patients with severe striae (1.69 ± 1.01, 1.73 ± 0.57, 2.67 ± 1.23, and 1.35 ± 1.06 for scar vascularity, pigmentation, pliability, and height respectively with a p-value of < 0.001 each). Thick intraperitoneal adhesions were noted significantly in women with severe striae [21 (43.75%), p-value < 0.001)]. The Davey's and Vancouver scores showed highly significant predictive performance in the prediction of intraperitoneal adhesions (p-value < 0.001). CONCLUSION: Abdominal striae and cesarean scar were significant predictors for intraperitoneal adhesions.

Skin Color May Predict Intra-Abdominal Adhesions During Repeated Caesarean Section Deliveries.

OBJECTIVE: Caesarean rates have increased rapidly for various reasons recently. One of the important reasons among these is medicolegal problems. Our aim with this study was to preoperatively predict abdominal adhesion density by combining the scar tissue morphology formed in the post-caesarean Pfannenstiel incision line and the skin color scoring of the patients. MATERIAL AND METHODS: Patients who had undergone one caesarean section previously, completed their terms (37-39 weeks) and were under 35 years old were included in the study. Skin color scoring of the patients was performed using the Fitzpatrick skin color scale. Intra-abdominal adhesion scoring of the participant patients was performed using Nair's adhesion scoring system. RESULTS: The change in abdominal adhesion scores was evaluated based on the Fitzpatrick color scale. Adhesion scores per the Nair intra-abdominal adhesion scoring system were found to be 0.04±0.209 in the FP1 group, 0.35±0.662 in the FP2 group, 1.58±0.923 in the FP3 group, and 2.33±0.577 in the FP4 group (p<0.05). These results showed a significant increase in adhesion density with increasing skin color darkness. Based on these results, it was observed that the abdominal adhesion scores and the frequency of depressed skin scar were significantly increased with increasing Fitzpatrick scores (p<0.05). CONCLUSION: The aim of this study was to increase the prediction rates by adding the skin color scoring to the scar tissue characteristics, which have been used in previous studies. The results of this study indicate that the combination of these two parameters may be more effective in predicting intra-abdominal adhesions. Nevertheless, there is a need for studies with a much higher number of patients and multiple parameters to be able to predict intra-abdominal adhesion density preoperatively with greater accuracy.

Comparison of maternal-neonatal results of vaginal birth after cesarean and elective repeat cesarean delivery.

OBJECTIVE: To evaluate maternal-neonatal results in women who underwent vaginal birth after cesarean (VBAC) and elec-tive repeat cesarean delivery (ERCD). MATERIAL AND METHODS: In a two-year retrospective cohort analysis, 423 patients with a history of prior cesarean section, singleton pregnancy with cephalic presentation and gestational age of 37-41 weeks were investigated. The maternal and perinatal outcomes of 195 patients desiring VBAC and undergoing a trial of labor after cesarean (TOLAC) attempt and 228 patients undergoing an ERCD were compared. RESULTS: While the TOLAC attempt was successful in 141 patients (72.3%), it was unsuccessful in 54 patients. No statistically significant difference was determined between VBAC and ERCD patients regarding uterine rupture, dehiscence, post-partum hemorrhage, the need for a blood transfusion and wound site infection (p > 0.05). When the post-partum neonatal outcomes were compared, there was no statistically significant difference between VBAC and ERCD groups regarding the prevalence of admission to the neonatal intensive care unit (NICU), respiratory distress, sepsis and birth injury (p > 0.05). CONCLUSION: The maternal and perinatal outcomes of our study may be encouraging in favor of VBAC particularly in countries with higher cesarean rates. We think that the option of VBAC should be offered more frequently for selected appropriate patients in created safe environments.

Timing of Repeat Cesarean Delivery for Women with a Prior Classical Incision.

OBJECTIVE: This study aimed to compare neonatal outcomes for delivery at 36 weeks compared with 37 weeks in women with prior classical cesarean delivery (CCD). STUDY DESIGN: This was a secondary analysis of the prospective observational cohort of the Eunice Kennedy National Institute for Child and Human Development's Maternal-Fetal Medicine Unit Network Cesarean Registry. Data on cases of repeat cesarean delivery (RCD) in the setting of a prior CCD were abstracted and used for analysis. This study compared outcomes of women who delivered at 360/7 to 366/7 versus 370/7 to 376/7 weeks. The primary outcome was a composite of adverse neonatal outcomes that included neonatal intensive care unit (NICU) admission, respiratory distress syndrome (RDS), transient tachypnea of the newborn (TTN), hypoglycemia, mechanical ventilation, sepsis, length of stay ≥5 days, and neonatal death. A composite of maternal outcomes that included uterine rupture, blood transfusion, general anesthesia, cesarean hysterectomy, venous thromboembolism, maternal sepsis, intensive care unit admission, and surgical complications was also evaluated. RESULTS: There were 436 patients included in the analysis. Women who delivered at 36 weeks (n = 176) were compared those who delivered at 37 weeks (n = 260). There were no differences in baseline characteristics. Delivery at 37 weeks was associated with a reduction in composite neonatal morbidity (24 vs. 34%, adjusted odds ratio [aOR] = 0.61 [0.31-0.94]), including a decrease in NICU admission rates (20 vs. 29%, aOR = 0.63 [0.40-0.99]), hospitalization ≥5 days (13 vs. 24%, aOR = 0.48 [0.29-0.8]), and RDS or TTN (9 vs. 19%, aOR = 0.43 [0.24-0.77]). There was no difference in adverse maternal outcomes (7 vs. 7%, aOR = 0.98 [0.46-2.09]). CONCLUSION: Delivery at 37 weeks for women with a history of prior CCD is associated with a decrease in adverse neonatal outcomes, compared with delivery at 36 weeks. KEY POINTS: · Classical cesarean section may have increased risk of uterine rupture in future pregnancies.. · This study compares outcomes of delivery at 370/7 to 376/7 versus 360/7 to 366/7 weeks.. · Delivery at 370/7 to 376/7 weeks was associated with decreased neonatal morbidity..

Outcomes of women age 40 or more undergoing repeat cesarean or trial of labor after cesarean.

AIM: Despite the increasing trend in delayed childbirth and the known associated complications in advancing maternal age, limited information exists regarding outcomes in very advanced maternal age by delivery type. This study aims to evaluate maternal and neonatal outcomes in women age 40 or more undergoing cesarean delivery or trial of labor after cesarean delivery. MATERIALS AND METHODS: We performed a secondary analysis of the Cesarean Section Registry Maternal-Fetal Medicine Units (MFMU) Network data, which was a prospective study of women undergoing repeat cesarean delivery or trial of labor after cesarean delivery from 1 January 1999 to 31 December 2002. Women age 40 years or more at the time of delivery were compared to the control group of women less than 40 years of age. RESULTS: There were 67,389 cases identified that met inclusion criteria. 2,436 (3.6%) were age ≥40 years old, and 65,403 (97.05%) were <40 at delivery. The >40 group had a higher rate of PRBC transfusion (aRR 1.75; 95% CI 1.20-2.56), maternal ICU admission (aRR 2.02; 1.41-2.89), bowel injury (aRR 3.65; 1.43-9.31), placenta accreta (aRR 1.92; 1.09-3.38) and classical uterine incision (aRR 1.59; 1.43-9.31) compared to the control group. Maternal death rates were similar in both groups (p = .30). CONCLUSION: Women aged 40 or more undergoing repeat cesarean delivery or trial of labor after cesarean delivery are more likely to have maternal complications including intraoperative transfusion, maternal ICU admission, abnormal placentation and surgical complications in comparison to women under age 40.
