Meta-Analysis Review
OBJECTIVE
To explore the outcome in women managed expectantly following the diagnosis of Cesarean scar pregnancy (CSP).
METHODS
An electronic search of MEDLINE, EMBASE and ClinicalTrials.gov databases was performed utilizing combinations of relevant medical subject headings for 'Cesarean scar pregnancy' and 'outcome'. Reference lists of relevant articles and reviews were hand-searched for additional reports. Observed outcomes included: severe first-trimester vaginal bleeding; clinical symptoms (abdominal pain, vaginal bleeding) requiring treatment; uncomplicated miscarriage; complicated miscarriage requiring intervention; first- or second-trimester uterine rupture or hysterectomy; third-trimester bleeding, uterine rupture or hysterectomy; maternal death; incidence of abnormally invasive placenta (AIP); prevalence of placenta percreta; ultrasound signs suggestive of AIP; and live birth. Meta-analyses of proportions using a random-effects model were used to combine data. Cases were stratified based on the presence or absence of embryonic/fetal heart activity at the time of diagnosis.
RESULTS
A total of 17 studies (69 cases of CSP managed expectantly, 52 with and 17 without embryonic/fetal heart beat) were included. In women with CSP and embryonic/fetal heart activity, 13.0% (95% CI, 3.8-26.7%) experienced an uncomplicated miscarriage, while 20.0% (95% CI, 7.1-37.4%) required medical intervention. Uterine rupture during the first or second trimester of pregnancy occurred in 9.9% (95% CI, 2.9-20.4%) of cases, while hysterectomy was required in 15.2% (95% CI, 3.6-32.8%) of all cases. Forty (76.9% (95% CI, 65.4-86.5%)) women progressed to the third trimester of pregnancy, of whom 39.2% (95% CI, 15.4-66.2%) experienced severe bleeding. Finally, 74.8% (95% CI, 52.0-92.1%) had a surgical or pathological diagnosis of AIP at delivery and around two-thirds (69.7% (95% CI, 42.8-90.1%)) of them had placenta percreta. In women with CSP but no embryonic/fetal cardiac activity, an uncomplicated miscarriage occurred in 69.1% (95% CI, 47.4-87.1%) of cases, while surgical or medical intervention during or immediately after miscarriage was required in 30.9% (95% CI, 12.9-52.6%). Uterine rupture during the first trimester of pregnancy occurred in 13.4% (95% CI, 2.7-30.3%) of cases, but hysterectomy was not required in any case.
CONCLUSIONS
CSP with positive embryonic/fetal heart activity managed expectantly is associated with a high burden of maternal morbidity including severe hemorrhage, early uterine rupture, hysterectomy and severe AIP. Despite this, a significant proportion of pregnancies complicated by CSP may progress to, or close to, term, thus questioning whether termination of pregnancy should be the only therapeutic option offered to these women. Expectant management of CSP with no cardiac activity may be a reasonable option in view of the low likelihood of maternal complications requiring intervention, although close surveillance is advisable to avoid adverse maternal outcome.

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.

Review
The primary cause of uterine scars is a previous cesarean. In women with a previous cesarean, the risks of maternal complications are rare and similar after a trial of labor after cesarean (TOLAC) and after an elective repeat cesarean delivery (ERCD), but the risk of uterine rupture is higher with TOLAC (level of evidence [LE]2). Maternal morbidity in women with previous cesareans is higher when TOLAC fails than when it leads to successful vaginal delivery (LE2). Although maternal morbidity increases progressively with the number of ERCD, maternal morbidity of TOLAC decreases with the number of successful previous TOLAC (LE2). The risk-benefit ratio considering the risks of short- and long-term maternal complications is favorable to TOLAC in most cases (LE3). Globally, neonatal complications are rare regardless of the mode of delivery for women with previous cesareans. The risks of fetal, perinatal, and neonatal mortality during TOLAC are low. Nonetheless, these risks are significantly higher than those associated with ERCD (LE2). The risks of mask ventilation, intubation for meconium-stained amniotic fluid, and neonatal sepsis all increase in TOLAC (LE2). The risk of transient respiratory distress increases in ERCD (LE2). To reduce this risk, and except in particular situations, ERCD must not be performed before 39 weeks (grade B). TOLAC is possible for women with a previous cesarean before 37 weeks, with 2 previous cesareans, with a uterine malformation, a low vertical incision or an unknown incision, with a myomectomy, postpartum fever, an interval of less than 6 months between the last cesarean delivery and the conception of the following pregnancy, if the obstetric conditions are favorable (professional consensus). ERCD is recommended in women with a scar in the uterine body (grade B) and a history of 3 or more cesareans (professional consensus). Ultrasound assessment of the risk of uterine rupture in women with uterine scars has not been shown to have any clinical utility and is therefore not recommended during pregnancy to help decide the mode of delivery (professional consensus). Use of X-ray pelvimetry to decide about TOLAC is associated with an increase in the repeat cesarean rate without any reduction in the rate of uterine rupture (LE2). It is unnecessary for deciding mode of delivery and for managing labor during TOLAC (grade C). TOLAC should be encouraged for women with a previous vaginal delivery either before or after the cesarean, a favorable Bishop score or spontaneous labor, and for preterm births (grade C). For women with a fetus with an estimated weight of more than 4500 g, especially in the absence of a previous vaginal delivery and those with supermorbid obesity (BMI>50), ERCD must be planned from the outset (grade C). For all of the other clinical situations envisioned (maternal age>35 years, diabetes, morbid obesity, prolonged pregnancy, breech presentation and twin pregnancy), TOLAC is possible but the available data do not allow specific guidelines about the choice of mode of delivery, in view of the low levels of proof (grade C). The decision about planned mode of delivery must be shared by the patient and her physician and made by the 8th month, taking into account the individual risk factors for TOLAC failure and uterine rupture (professional consensus). TOLAC is the preferred choice for women who do not have several risk factors (professional consensus). The availability onsite of an obstetrician and anesthetist must be pointed out to the patient. If the woman continues to prefer a repeat cesarean after adequate information and time to think about it, her preference should be honored (professional consensus). Labor should be induced in woman with a previous cesarean only for medical indications (professional consensus). Induction of labor increases the risk of uterine rupture, which can be estimated at 1% if oxytocin is used and 2% with vaginal prostaglandins (LE2). Mechanical methods of induction have not been studied sufficiently. Misoprostol appears to increase the risk of uterine rupture strongly (LE4). Based on the information now available, its use is not recommended (professional consensus). Routine use of internal tocodynamometry does not prevent uterine rupture (professional consensus). The increased risk of uterine rupture associated with oxytocin use is dose-dependent (LE3). In the active phase, it is recommended that the total duration of failure to progress should not exceed 3h; at that point, a cesarean should be performed (professional consensus). Epidural analgesia must be encouraged. The simple existence of a uterine scar is not an indication for a routine manual uterine examination after VBAC (grade C).

This case report describes a uterine rupture initially misinterpreted as acute appendicitis. Uterine rupture is a rare but serious obstetric complication, whereas acute appendicitis is one of the most common causes of abdominal pain. The patient gave vaginal birth after previously having had a caesarean delivery. The following days she experienced persistent abdominal pain which was interpreted as acute appendicitis. Diagnostic laparoscopy found a normal appendix but a complete uterine rupture. The lesson to be learned from this case report is not to let the most common diagnoses overshadow the rare ones.

Review
INTRODUCTION
There is concern about the risk of uterine rupture in the subsequent pregnancy after myomectomy. This risk is reported in literature to be around 0.7-1%. The aim of this study was to evaluate the incidence of uterine rupture and associated risk factors in women who had a trial of labor after prior myomectomy.
MATERIAL AND METHODS
A systematic review of the literature was performed including all cohort studies with at least five cases reporting outcomes of pregnancies after prior myomectomy. The terms "myomectomy", "pregnancy", "trial of labor" and "uterine rupture" were used in PubMed and EMBASE searches for identification purposes. Every reference was reviewed for possible inclusion and all eligible cases of uterine rupture were considered.
RESULTS
Twenty-three studies with at least five cases of pregnancy after myomectomy were identified, with an overall incidence of uterine rupture of 0.6% (0.3-1.1%) (n = 11/1825). Of these 23 studies, 11 studies reported detailed data about trial of labor after myomectomy and related pregnancy outcomes, including 1034 pregnancies and 756 viable (≥24 weeks) deliveries. The overall incidence of uterine rupture after myomectomy in the included studies was 0.93% (0.45-1.92%) (n = 7/756); specifically, it was 0.47% (0.13-1.70%) (n = 2/426) in women undergoing trial of labor after myomectomy, and 1.52% (0.65-3.51%) (n = 5/330) in women before the onset of labor. Of the seven uterine ruptures, five (71%) occurred within 36 weeks (range 24-40 weeks).
CONCLUSIONS
Trial of labor after myomectomy is associated with a 0.47% risk of uterine rupture. There were no identified risk factors among the variables studied. The present systematic review of the literature revealed that uterine rupture after prior myomectomy occurred mainly before 36 weeks and before labor.

Observational Study
INTRODUCTION
Uterine rupture is uncommon but has catastrophic implications on the pregnancy. A scarred uterus and abnormal placentation are known contributory factors. The aim of our study was to review the contributing factors, clinical presentation, complications and management of uterine rupture in our population in light of the changing nature of modern obstetric practices.
METHODS
A retrospective observational study was conducted at KK Women's and Children's Hospital by studying proven cases of uterine rupture in the period between January 2003 and December 2014. These cases were analysed according to their past history, clinical presentation, complications, management and outcome.
RESULTS
A total of 48 cases of proven uterine rupture were identified. The incidence of uterine rupture was 1 in 3,062 deliveries. The ratio of scarred uterus rupture to unscarred uterus rupture was approximately 3:1. The most common factor was previous lower segment caesarean section for the scarred group, followed by a history of laparoscopic myomectomy. Abdominal pain was the common clinical presentation in the antenatal period, while abnormal cardiotocography findings were the most common presentation in intrapartum rupture.
CONCLUSION
There is a notable shift in the trend of uterine rupture cases given the increasing use of laparoscopic myomectomy and elective caesarean sections. While ruptures from these cases were few, their presentation in the antenatal period calls for diligent monitoring with informed patient involvement in their pregnancy care.

Obstetrics and Gynecology Dec 2023We aimed to quantify the incidence of recurrent uterine rupture in pregnant women. (Meta-Analysis)
Meta-Analysis
OBJECTIVE
We aimed to quantify the incidence of recurrent uterine rupture in pregnant women.
DATA SOURCES
A literature search of PubMed, Web of Science, Cochrane Central, and ClinicalTrials.gov for observational studies was performed from 2000 to 2023.
METHODS OF STUDY SELECTION
Of the 7,440 articles screened, 13 studies were included in the final review. We included studies of previous uterine ruptures that were complete uterine ruptures , defined as destruction of all uterine layers, including the serosa. The primary outcome was the pooled incidence of recurrent uterine rupture. Between-study heterogeneity was assessed with the I2 value. Subgroup analyses were conducted in terms of the country development status, year of publication, and study size (single center vs national study). The secondary outcomes comprised the following: 1) mean gestational age at which recurrent rupture occurred, 2) mean gestational age at which delivery occurred without recurrent rupture, and 3) perinatal complications (blood loss, transfusion, maternal mortality, and neonatal mortality).
TABULATION, INTEGRATION, AND RESULTS
A random-effects model was used to pool the incidence or mean value and the corresponding 95% CI with R software. The pooled incidence of recurrent uterine rupture was 10% (95% CI 6-17%). Developed countries had a significantly lower uterine rupture recurrence rate than less developed countries (6% vs 15%, P =.04). Year of publication and study size were not significantly associated with recurrent uterine rupture. The mean number of gestational weeks at the time of recurrent uterine rupture was 32.49 (95% CI 29.90-35.08). The mean number of gestational weeks at the time of delivery without recurrent uterine rupture was 35.77 (95% CI 34.95-36.60). The maternal mortality rate was 5% (95% CI 2-11%), and the neonatal mortality rate was 5% (95% CI 3-10%). Morbidity from hemorrhage, such as bleeding and transfusion, was not reported in any study and could not be evaluated.
CONCLUSION
This systematic review estimated a 10% incidence of recurrent uterine rupture. This finding will enable appropriate risk counseling in patients with prior uterine rupture.

Revista Brasileira de Ginecologia E... Nov 2021To compare maternal and perinatal risk factors associated with complete uterine rupture and uterine dehiscence.
OBJECTIVE
To compare maternal and perinatal risk factors associated with complete uterine rupture and uterine dehiscence.
METHODS
Cross-sectional study of patients with uterine rupture/dehiscence from January 1998 to December 2017 (30 years) admitted at the Labor and Delivery Unit of a tertiary teaching hospital in Canada.
RESULTS
There were 174 (0.1%) cases of uterine disruption (29 ruptures and 145 cases of dehiscence) out of 169,356 deliveries. There were associations between dehiscence and multiparity (odds ratio [OR]: 3.2; = 0.02), elevated maternal body mass index (BMI; OR: 3.4; = 0.02), attempt of vaginal birth after a cesarian section (OR: 2.9; = 0.05) and 5-minute low Apgar score (OR: 5.9; < 0.001). Uterine rupture was associated with preterm deliveries (36.5 ± 4.9 versus 38.2 ± 2.9; = 0.006), postpartum hemorrhage (OR: 13.9; < 0.001), hysterectomy (OR: 23.0; = 0.002), and stillbirth (OR: 8.2; < 0.001). There were no associations between uterine rupture and maternal age, gestational age, onset of labor, spontaneous or artificial rupture of membranes, use of oxytocin, type of uterine incision, and birthweight.
CONCLUSION
This large cohort demonstrated that there are different risk factors associated with either uterine rupture or dehiscence. Uterine rupture still represents a great threat to fetal-maternal health and, differently from the common belief, uterine dehiscence can also compromise perinatal outcomes.

Review
: Since spontaneous uterine rupture in the mid-trimester is rare, maternal and fetal outcomes in subsequent pregnancies remain unclear. Therefore, this study aimed to examine the maternal and fetal outcomes of subsequent pregnancies after prior mid-trimester uterine rupture. : A systematic review using PubMed, the Cochrane Central Register of Controlled Trials, and Scopus until 30 September 2021, was conducted in compliance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The studies that clarified the maternal and fetal outcomes after prior mid-trimester uterine rupture and our case ( = 1) were included in the analysis. : Among the eligible cases, there were five women with eight subsequent pregnancies after prior mid-trimester uterine rupture. The timing of prior mid-trimester uterine rupture ranged from 15 to 26 weeks of gestation. The gestational age at delivery in subsequent pregnancies was 23-38 gestational weeks. Among the included cases ( = 8), those involving prior mid-trimester uterine rupture appeared to be associated with an increased prevalence of placenta accreta spectrum (PAS) ( = 3, 37.5%) compared with those involving term uterine rupture published in the literature; moreover, one case exhibited recurrent uterine rupture at 23 weeks of gestation (12.5%). No maternal deaths have been reported in subsequent pregnancies following prior mid-trimester uterine rupture. Fetal outcomes were feasible, except for one pregnancy with recurrent mid-trimester uterine rupture at 23 weeks of gestation, whose fetus was alive complicated by cerebral palsy. : Our findings suggest that clinicians should be aware of the possibility of PAS and possible uterine rupture in pregnancies after prior mid-trimester uterine rupture. Further case studies are warranted to assess maternal and fetal outcomes in pregnancies following prior mid-trimester prior uterine rupture.
