Introduction: About one in 500 pregnant women requires a surgical intervention that is not pregnancy-related. One of the most common surgical interventions during pregnancy is appendectomy. The primary aim of this study was to assess surgical access of appendectomy during pregnancy and pregnancy outcome. Secondary outcomes were clinical symptoms and diagnostics as well as histopathological analysis., Methods and Material: This is a single-center retrospective data analysis conducted at a tertiary perinatal center. A digital search of the hospital record archive was conducted focusing on pregnant women beyond 24 0/7 weeks of pregnancy encoding appendectomy. Descriptive statistical analysis was performed., Results: Between January 2013 and January 2023, a total of 20 appendectomies were performed during pregnancy with gestational age beyond 24 0/7 weeks of pregnancy. All of them were performed as lower midline laparotomy. The rate of appendix perforation was 3/20 (15.0%). 19/20 patients (95.0%) delivered via cesarean. In 7/20 patients (35.0%) appendectomy was performed during cesarean delivery due to incidental finding of irritated or abnormal vermiform appendix. In the pathological work-up, only 2/7 (28.6%) of these subjects had inflammation., Conclusion: In this small monocentric cohort, only open appendectomies were performed. Our data indicate that it is safe to perform open appendectomy during pregnancy if necessary. In this small patient group, there was an increase in simultaneous cesarean deliveries., Competing Interests: Conflict of Interest The authors declare that they have no conflict of interest., (The Author(s).

Mechanical methods have gained growing interest for pre-induction cervical ripening in women with an unripe cervix, since they have a better safety profile compared to prostaglandins. Balloon catheters have been the gold standard method for decades, while there was a lack of data on synthetic osmotic cervical dilators. Not until 2015, when Dilapan-S was approved by the Food and Drug Administration (FDA) for induction of labor, numerous studies have been published on the use of Dilapan-S in this field. The rate of vaginal deliveries associated with the use of Dilapan-S ranges from 61.6 to 81.7%, and no serious complications needing further interventions have been reported to this date. Dilapan-S was shown to be as effective as the Foley balloon catheter as well as the 10 mg PGE 2 vaginal insert and orally applied misoprostol (25 µg every 2 hours) in achieving vaginal delivery, but patient's satisfaction during the cervical ripening process was significantly higher compared to the other methods and the rate of uterine hyperstimulation was significantly lower compared to prostaglandins (PGs). Minor complications (e.g. vaginal bleeding) associated with the use of Dilapan-S were < 2%, and maternal infectious morbidity was not higher compared to Foley balloon and vaginal PGE 2 or misoprostol. Due to these beneficial properties Dilapan-S might be an ideal option for outpatient cervical ripening, as shown in a recent randomized clinical trial comparing inpatient to outpatient cervical ripening. Furthermore, according to the manufacturers' product information, Dilapan-S is the only cervical ripening method that is not contraindicated for induction of labor in women with a previous cesarean section. Upcoming guidelines should consider synthetic osmotic cervical dilators as an effective and safe method for cervical ripening/induction of labor acknowledging that more evidence-based data are mandatory, particularly in patients with a previous cesarean section., Competing Interests: Conflict of Interest Patrick Stelzl has a part-time job agreement as consultant and speaker and is member of the Steering Committee in concerns of the LION (“Labour Induction Outcomes Network”) project for Angusta 25 µg tablets from Norgine Pharma GmbH.

There are currently no up-to-date evidence-based recommendations on the preferred method to induce labour after previous Caesarean section, especially for patients with unripe cervix, as randomised controlled studies are lacking. Intravenous oxytocin and misoprostol are contraindicated in these women because of the high risk of uterine rupture. In women with ripe cervix (Bishop Score > 6), intravenous administration of oxytocin is an effective procedure with comparable rates of uterine rupture to those with spontaneous onset of labour. Vaginal prostaglandin E 2 (PGE 2 ) and mechanical methods (balloon catheters, hygroscopic cervical dilators) are effective methods to induce labour in pregnant women with unripe cervix and previous Caesarean section. According to current guidelines, the administration of PGE 2 is associated with a higher rate of uterine rupture compared to balloon catheters. Balloon catheters are therefore a suitable alternative to PGE 2 to induce labour after previous Caesarean section, even though this is an off-label use. In addition to two meta-analyses published in 2016, 12 mostly retrospective cohort/observational studies with low to moderate levels of evidence have been published on mechanical methods of cervical ripening after previous Caesarean section. But because of the significant heterogeneity of the studies, substantial differences in study design, and insufficient numbers of pregnant women included in the studies, it is not possible to make any evidence-based recommendations based on these studies. According to a recent meta-analysis, the average rate using balloon catheters is approximately 53% and the average rate after spontaneous onset of labour is 72%. The uterine rupture rate was 0.2-0.9% for vaginal PGE 2 and 0.56-0.94% for balloon catheters and is therefore comparable to the uterine rupture rate associated with spontaneous onset of labour. According to the product informations, hygroscopic cervical dilators (Dilapan-S) are currently the only method which is not contraindicated for cervical ripening/induction of labour in women with previous Caesarean section, although data are insufficient. Well-designed, randomised, controlled studies with sufficient case numbers comparing balloon catheters and hygroscopic cervical dilators with mechanical methods and vaginal prostaglandin E 2 /oral misoprostol are therefore necessary to allow proper decision-making., Competing Interests: Conflict of Interest Patrick Stelzl has a part-time job agreement as consultant and speaker and is member of the Steering Committee in concerns of the LION (“Labour Induction Outcomes Network”) project for Angusta 25 µg tablets from Norgine Pharma GmbH. / Patrick Stelzl hat eine werksvertraglich geregelte nebenberufliche Berater- und Referenten-Tätigkeit und ist Steering Committee Mitglied im Rahmen des LION („Labour Induction Outcomes Network“) Projektes für das Einleitungs-Präparat Angusta 25 µg Tabletten von der Firma Norgine Pharma GmbH., (The Author(s).

Introduction: Perinatal data of women with a Vietnamese migration background have not been systematically studied in Germany to date. Numerous details of important maternal and child outcomes were compared and analysed. The study's primary parameters were the frequency of and indication for c-section., Methodology: The perinatal data from a Berlin hospital were analysed retrospectively. The women (Vietnamese migration background vs. autochthonous) were grouped using name analysis. Datasets of 3002 women giving birth, including 999 women with a Vietnamese migration background, were included. The associations between primary or secondary cesarean delivery and different child outcomes depending on the migration background (exposure) were studied using logistical regression analysis., Results: Women with a Vietnamese migration background have a lower c-section rate of 8.0% for primary and 12.6% for secondary c-section than women without a migration background (11.1% primary and 16.4% secondary c-section respectively). Regression analysis shows that the odds that women with a Vietnamese migration background will have a primary (OR 0.75; p = 0.0884) or secondary c-section (OR 0.82; p = 0.1137) are not significantly lower. A Vietnamese migration background was associated with higher odds for an episiotomy but not for a grade 3 - 4 perineal tear. A Vietnamese migration background does not have a significant influence on poor 5-min Apgar scores ≤ 7 and low umbilical cord arterial pH values ≤ 7.10. Newborns of mothers with a Vietnamese migration background have higher odds of a relatively higher birth weight (> 3110 g)., Summary: There was no evidence that women with a Vietnamese migration background are delivered more often by caesarean section. There were also no differences as regards important child outcome data from women in the comparator group. Overall, the results do not provide any evidence for poorer quality of care of women with a Vietnamese migration background in Berlin despite the cultural and communication barriers in the reality of care provision.

Background: There are a number of threatening liver diseases that occur during pregnancy. Acute fatty liver of pregnancy is a rare disease associated with high maternal and foetal mortality. Case Report: We report on a young gravida 1 woman who presented to our level 1 perinatal centre in the 36 + 5 week of pregnancy with an isolated elevation of transaminases together with diffuse upper abdominal complaints. After comprehensive diagnostic work-up we performed an emergency delivery by Caesarean section. This was followed by interdisciplinary management. Discussion: The differentiation from other liver diseases seems not to be obvious in all cases. Here we consider the following differential diagnoses: hyperemesis gravidarum, intrahepatic gestational cholestasis, preeclampsia, HELLP syndrome. Conclusion: Rapid diagnosis and delivery as well as interdisciplinary aftercare are necessary in order to reduce maternal and foetal mortality.
