Vaginal operative delivery in Germany: a national survey about experience and self-reported competency.

BACKGROUND: To determine German obstetricians' self-perceived experience with vacuum and forceps deliveries. PATIENTS AND METHODS: Using a web-based survey, German obstetricians were invited to participate in a survey. This survey was approved by the German society of obstetrics and gynecology. RESULTS: Surveys of 635 obstetricians were received. All obstetricians reported performing significantly less forceps than vacuum deliveries. Almost all obstetricians want to perform more delivery, which indicates the willingness to learn both. More obstetricians felt confident to perform vacuum than forceps. In a similar obstetrical indication, most of the obstetricians would prefer to perform a vacuum assisted delivery. The majority of the obstetricians wished to receive more training in vaginal operative deliveries. CONCLUSION: Most of the German obstetricians prefer to use vacuum-assisted vaginal deliveries and feel less confident to perform forceps deliveries. Standardized training to improve the quality of care is recommended.

Teaching undergraduate students gynecological and obstetrical examination skills: the patient's opinion.

INTRODUCTION: Our study assesses the patients' opinion about gynecological examination performed by undergraduate students (UgSts). This assessment will be used in improving our undergraduate training program. A positive opinion would mean a lower chance of a patient refusing to be examined by a tutor or student, taking into account vaginal examination (VE). MATERIALS AND METHODS: We performed a prospective cross-sectional survey on 1194 patients, consisting of outpatient and inpatient at the departments of obstetrics and gynecology from November 2015 to May 2016. The questionnaire consisted of 46 questions. Besides demographic data, we assessed the mindset of patients regarding the involvement of undergraduate student (UgSt) in gynecological and obstetrical examinations. We used SPSS version 23 for the statistical analysis. For reporting the data, we followed the STROBE statement of reporting observational studies. RESULTS: The median age was 38 years having a median of one child. 34% presented due to obstetrical problems, 38% due to gynecological complaints, and 19% due to known gynecological malignancies. Generally, we retrieved a positive opinion of patients towards the involvement of students in gynecological and obstetrical examination under supervision in 2/3 of the cases. CONCLUSIONS: There is no reason to exclude medical UgSts from gynecological and obstetrical examinations after obtaining a written or oral consent.

Introduction of a student tutor-based basic obstetrical ultrasound screening in undergraduate medical education.

BACKGROUND: While there is an increasing interest in incorporating ultrasound in undergraduate medical education and the use of student tutors in conveying this medical skill to assist faculty members, little is known about undergraduate ultrasound teaching in obstetrics and gynecology. METHODS: After a 3 week training of the student tutors, the student tutors joined an undergraduate ultrasound educational program to teach practical round students. After being certified, the student tutors organized a pre-test, gave a presentation about ultrasound, and then supervised the hands on ultrasound course under faculty staff supervision for round students. Finally, the practical round students had to answer a post-test with image recognition. The practical round students had to evaluate the course using a Likert scale. RESULTS: 111 students joined this ultrasound course. The objective theoretical and practical multiple-choice questions' (MCQ) test showed a statistically significant improvement (50 vs. 90%, p < 0.05). The practical round students expressed a high acceptance (Likert 1.7) and subjective medical skill learning (Likert 1.8). The students also positively graded the student tutors (Likert 1.3). CONCLUSION: Student tutor-based undergraduate obstetrical and gynecological ultrasound course is a useful method to teach a medical skill and is well accepted by students.

Pilot study: placental biomarker predictive capability (sFlt-1, PlGF and their ratio) of postpartum maternal outcome.

BACKGROUND: Prenatal measurement of placental biomarkers was able to improve screening and diagnosis of preeclampsia. Little is known about the clinical role of placental biomarkers in the postpartum period. METHODS: This study is a prospective monocentric trial that included a total of 30 women with preeclamptic pregnancies. Serum placental biomarkers including soluble fms-like tyrosine kinase 1 (sFlt-1) and placental growth factor (PlGF) were measured before and 2 h after delivery by Enzyme-Linked Immunosorbent Assay (ELISA) using commercially available kits according to manufacturer's instructions and correlated with the postpartum outcome. RESULTS: Postpartum higher serum PlGF level was associated with postpartum elevation of the systolic blood pressure. Yet, the placental biomarkers were not able to predict general worsening of postpartum preeclampsia or other individual clinical or laboratory parameters. CONCLUSION: Serum concentrations of sFlt-1 and PlGF or their ratio in our study cohort did not completely predict the occurrence of postpartum preeclampsia. Yet, postpartum higher serum PlGF level was associated with postpartum elevation of the systolic blood pressure.

Conversion of intraperitoneal cytology during laparoscopic surgery of uterine cancer.

INTRODUCTION: The laparoscopic surgery of uterine cancer is an oncological safe treatment option in early stage cancer. However, there are no data about whether laparoscopy can lead to intraperitoneal tumor cell dissemination. We aimed in our study to detect a possible cytological conversion during laparoscopic procedures. METHODS: In this prospective study, we included all patients receiving laparoscopic treatment at the early stage endometrial and cervical cancer in the Department of Obstetrics and Gynecology at the University of the Saarland and obtained peritoneal wash for cytological examination at the beginning and at the end of laparoscopic surgery. All patients received stage-adjusted operative and adjuvant therapy. RESULTS: We enrolled 43 patients [endometrial cancer (n = 24) and cervical cancer (n = 19)]. At the beginning of the operation, one patient with endometrial cancer and one patient with cervical cancer showed a positive cytology. One tumor cell conversion from negative to positive cytology during surgery was detected in a patient suffering from endometrial cancer stage FIGO Ia. The median duration of surgery was 191.8 ± 79.3 min. The average time of follow-up was 16.5 ± 10.3 month. At the end of data evaluation at December 2014, two patients (8.6 %) are suffering from recurrent disease, two patients died, none of these patients had a positive cytology. All patients with positive cytology are free of cancer. CONCLUSION: During laparoscopic surgery of early stage endometrial and cervical cancer, only one conversion of cytology was detected, which proves that laparoscopy does not appear to increase the intraoperative tumor cell dissemination or rate of positive cytological results.

Diagnostic Methods of Ectopic Pregnancy and Early Pregnancy Loss: a Review of the Literature.

This review article presents recent evidence on early pregnancy loss and ectopic pregnancy. In the light of recent evidence, the ß-hCG discriminatory zone may be extended in clinically stable cases without evidence of bleeding. A possible cut-off is 4300 mIU/ml, which corresponds to when a sonographer should detect an intrauterine pregnancy. Embryonic demise can be confirmed when a transvaginal ultrasound finding shows no heartbeat in an embryo of more than 7 mm CRL, no embryo in a gestational sac having a mean sac diameter of more than 25 mm, or no appearance of an embryo within 7-10 days after the primary examination. These are considered definitive signs of embryonic demise. Suggestive signs of embryonic demise require closer monitoring of the pregnancy.

Influence of the Preoperative Decision-Making Process on the Postoperative Outcome after Hysterectomy for Benign Uterine Pathologies.

Introduction: The aim of this study was to assess whether the preoperative decision-making process might influence treatment success in premenopausal women undergoing hysterectomy for benign uterine pathologies Materials and Methods: All premenopausal women treated with hysterectomy for benign uterine pathologies between April 2011 and June 2013 at a tertiary university center were enrolled in this prospective observational cohort study. Five parameters of the preoperative decision-making process were assessed upon their correlation with postoperative quality of life, sexual function and patients' satisfaction. These outcome measures were assessed for the pre- and postoperative (six months after surgery) status using two validated questionnaires (EQ-5D and "female sexual function index" (FSFI). Patients' satisfaction with the postoperative outcome was assessed with a self-developed questionnaire. Results: 255 of 402 (63 %) patients completed the study. A correlation between the co-variables "interval between first counseling and decision to surgery", "subjectively perceived quality of the preoperative counseling" and "certainty in the decision for the intervention" and postoperative outcomes were found. The co-variables "person mainly responsible for election of hysterectomy mode" and "discussion of decision for surgery with others" showed no influence on postoperative patients-reported outcomes. Conclusion: We found a correlation between certain parameters of the preoperative decision-making process and postoperative patient-reported sexual function, quality of life and patients' satisfaction in premenopausal women undergoing hysterectomy for benign uterine pathologies. An optimization of these factors could contribute to an improvement in treatment outcomes.

Introduction of basic obstetrical ultrasound screening in undergraduate medical education.

PURPOSE: Teaching ultrasound procedures to undergraduates has recently been proposed to improve the quality of medical education. We address the impact of applying standardized ultrasound teaching to our undergraduates. METHODS: Medical students received an additional theoretical and practical course involving hands-on ultrasound screening during their mandatory practical training week in obstetrics and gynecology. The students' theoretical knowledge and fetal image recognition skills were tested before and after the course. After the course, the students were asked to answer a course evaluation questionnaire. To standardize the teaching procedure, we used Peyton's 4-Step Approach to teach the skills needed for a German Society of Ultrasound in Medicine Level 1 ultrasound examiner. RESULTS: The multiple-choice question scores after the course showed statistically significant improvement (50 vs. 80 %; P < 0.001). The questionnaire revealed that students were satisfied with the course, felt that it increased their ultrasound knowledge, and indicated that they wanted more sonographic hands-on training in both obstetrics and gynecology and other medical fields. CONCLUSION: Using practical, hands-on medical teaching is an emerging method for undergraduate education that should be further evaluated, standardized, and developed.

Deciding Factors for the Referral of a Female Patient to a Specific Hospital from the Viewpoint of Practice-Based Specialists.

Background: One of the key points of patient care is the cooperation between practice-based specialists and clinical facilities. The present study was undertaken in order to illustrate the deciding factors, from the viewpoint of practice-based specialists, for the referral of a female patient to a specific hospital. Methods: Altogether a total of 322 practice-based specialists from various disciplines were contacted in writing and sent a questionnaire. In this survey the recipients were questioned about the criteria, in order of importance, applied for the referral of a (female) patient to a specific clinical facility. Results: In the foreground for the referral of a patient to a specific hospital are the aspects of medical quality and competence. On a closer look we find the surgical spectrum, especially the availability of endoscopic and special operations as a main factor. Further factors are a low rate of complications and the availability of modern diagnostic methods. Also evaluated as an important aspect was the easy reachability of a competent consultant. Factors of lower relevance for referral behaviour were personal familiarity with the colleagues employed in the hospital, specific further training events and the course of previous cooperation. Conclusions: A modern diagnostic and therapeutic spectrum coupled with an easy reachability of competent contact partners are the main factors for cooperation from the viewpoint of the practice-based specialist. Of lowest relevance, among others, was the aspect of previous cooperation. Thus, it can be seen that by means of changes in cooperation an improvement in patient care can be achieved at any time.

Standardised Registration of Surgical Complications in Laparoscopic-Gynaecological Therapeutic Procedures Using the Clavien-Dindo Classification.

Introduction: The registration of complications represents an important component in the evaluation of surgical therapeutic procedures. The aim of the present study was to examine the frequency of occurrence as well as the severity of surgical complications after laparoscopic-gynaecological operations in a standardised manner using the Clavien-Dindo system. Material and Methods: Altogether 7438 treatment courses after laparoscopic-gynaecological interventions by 9 working groups were evaluated. Covariates recorded were the technical complexity of the operation, type of study cohort, study size, data acquisition as well as study centre. Target variables recorded were the surgical morbidity rate, subdivided into mild (Clavien-Dindo grade I-II) and severe complications (Clavien-Dindo grade III-V). In addition, a binary logistic regression analysis for the mentioned covariates and the occurrence of surgical complication was carried out. Results: 946 complications were recorded (overall complication rate: 13 %). These included 664 mild complications (8.9 %) and 305 severe complications (4.1 %). A correlation was found between the covariates technical complexity (relative risk [rR] 1.37; p < 0.01), study size (rR: 0.35; p < 0.01) and study centre (rR 0.19; p < 0.01) and the occurrence of surgical complications. Conclusion: By means of a standardised registration of complications using the Clavien-Dindo classification it appears to be possible to limit the methodologically caused underestimation of surgical morbidity in the retrospective evaluation of gynaecological-endoscopic therapeutic procedures. Factors decisively influencing the surgical morbidity of gynaecological-laparoscopic therapeutic procedures are the respective operative experience of the treating facility as well as the technical complexity of the intervention.

Prenatal diagnosis and management of an intestinal volvulus with meconium ileus and peritonitis.

Fetal intestinal volvulus is a rare but serious finding with a high risk of potential life threatening fetal complications. Delay in diagnosis or treatment can increase mortality and morbidity. We report a case of mild fetal bowel dilatation at 30 weeks of gestation and intestinal volvulus presented by the 'whirl-sign', intestinal perforation and meconium peritonitis with fetal ascites and polyhydramnios at 33 weeks of gestation. This case emphasizes the role of examination of the bowel in third trimester ultrasound and the importance of quick decision to delivery and interdisciplinary perinatal management at suspected fetal volvulus with bowel necrosis and intraabdominal bleeding.

[Fetal MRI and ultrasound of congenital CNS anomalies]. / Fetales MRT und Ultraschall der angeborenen ZNS-Fehlbildungen.

In the last decade the newest technologies, fetal magnetic resonance imaging (MRI) and 3D ultrasound, have given an insight into the minute structures of the fetal brain. However, without knowledge of the basic developmental processes the imaging is futile. Knowledge of fetal neuroanatomy corresponding to the gestational week is necessary in order to recognize pathological structures. Furthermore, a modern neuroradiologist should be acquainted with the three steps in the formation of the cerebral cortex: proliferation, migration and differentiation of neurons in order to be in a position to suspect that there is a pathology and start recognizing and discovering the abnormalities. The fetal MRI has become an important complementary method to ultrasound especially in cortical malformations when confirmation of the prenatal diagnosis is needed and additional pathologies need to be diagnosed. In this manner these two methods help in parental counseling and treatment planning.

Polyhydramnios: Causes, Diagnosis and Therapy.

Polyhydramnios is defined as a pathological increase of amniotic fluid volume in pregnancy and is associated with increased perinatal morbidity and mortality. Common causes of polyhydramnios include gestational diabetes, fetal anomalies with disturbed fetal swallowing of amniotic fluid, fetal infections and other, rarer causes. The diagnosis is obtained by ultrasound. The prognosis of polyhydramnios depends on its cause and severity. Typical symptoms of polyhydramnios include maternal dyspnea, preterm labor, premature rupture of membranes (PPROM), abnormal fetal presentation, cord prolapse and postpartum hemorrhage. Due to its common etiology with gestational diabetes, polyhydramnios is often associated with fetal macrosomia. To prevent the above complications, there are two methods of prenatal treatment: amnioreduction and pharmacological treatment with non-steroidal anti-inflammatory drugs (NSAIDs). However, prenatal administration of NSAIDs to reduce amniotic fluid volumes has not been approved in Germany. In addition to conventional management, experimental therapies which would alter fetal diuresis are being considered.

Pathological prenatal Doppler sonography findings and their association with neonatal cranial ultrasound abnormalities in a high risk collective.

The aim of this study was to evaluate whether prenatal Doppler ultrasound plays a role in the risk assessment of neonatal abnormal cranial ultrasound findings (NACU). Doppler examinations of blood flow velocities in the umbilical artery (n = 132), the fetal middle cerebral artery (n = 96) and the ductus venosus (n = 46) were conducted in 132 consecutive high-risk cases. The cases were divided into three groups: normal (I), pathological (II) and highly pathological Doppler (III) results, according to the resistance index calculated and were assessed for any association between the Doppler groups and the short-term outcome of the neonate, especially NACU. A significant association was found between Doppler groups and gestational age at delivery, birth weight, length and head circumference, growth restriction, cesarean section rate, Apgar score and pH values. NACU was diagnosed significantly more often in the pathological (12.1%) and highly pathological (38.5%) Doppler groups than in the group with normal Doppler (1.7%; p < 0.001). Multivariate analysis showed that the Doppler groups (odds ratio 1.67, 95% confidence interval [CI] 1.14-2.84, p < 0.001) and gestational age at delivery (odds ratio 1.37, 95% CI 1.08-2.74; p < 0.001) were independent variables that could be used to predict NACU. The present study showed that a pathological prenatal Doppler result is highly predictive for NACU in addition to gestational age and can therefore be used for risk assessment.

Prenatal ultrasound diagnosis, follow-up, and outcome of congenital varicella syndrome.

OBJECTIVES: To report on a case of fetal varicella infection following the diagnosis of maternal infection at 16 weeks of gestation. METHODS: Diagnosis was based on serology testing and prenatal ultrasound, confirmed by DNA detection in amniotic fluid (Lightcycler-PCR). Serial ultrasound examinations were performed. RESULTS: Sonographic anomalies included borderline ventriculomegaly, intracerebral, intrahepatic and myocardial calcifications, limb deformities, articular effusions, and intrauterine growth retardation (confirmed postpartally). The newborn showed a severe encephalopathy and could not be stabilized sufficiently. The child died 23 days after birth. CONCLUSION: The outcome of an affected fetus may be very serious and prenatal ultrasound is a helpful tool to recognize the severity of the infection.

Cystic colon duplication as differential diagnosis to ovarian cyst.

OBJECTIVE: We report the case of a female fetus with a single spherical anechoic cyst on the right side of the lower abdomen first diagnosed at 22 weeks of pregnancy. METHODS: Serial ultrasound monitoring and needle aspiration of the cyst were performed. RESULTS: The cyst grew during pregnancy up to 8 cm diameter. Needle aspiration was performed at 33 and 36 weeks. At 38 weeks labor was induced and a girl was delivered spontaneously. Postnatally the child showed abdominal distention, vomiting, and an obstruction of venous return of the right leg. To improve venous circulation, another needle aspiration of the cyst was performed. Laparoscopy revealed cystic colon duplication. CONCLUSIONS: Prenatal differentiation of a single round anechoic cyst in the pelvis of a female fetus can be difficult. As a rare abnormality cystic colon duplication has to be considered.

Hemodynamic changes with phenotype reversal during pregnancy in twin-twin transfusion syndrome.

OBJECTIVES: We report an atypical case of twin-twin transfusion syndrome (TTTS) in monochorionic-diamniotic twins with arterio-arterial anastomoses in which the former donor became the recipient during pregnancy. METHODS: Serial sonographic monitoring was performed. RESULTS: There was a phenotype reversal in TTTS concerning growth and amniotic fluid ending at 27 weeks, with the dominance of the former smaller donor. Doppler sonography changed from absent enddiastolic flow of the donor to normal values in both twins. The new recipient showed transient ascites, the now smaller actual donor (former recipient) developed progressive cardiomegaly, hypertrophy of the myocardium and mitral and tricuspid insufficiency at 29 weeks. Doppler sonography in the new donor deteriorated to highly pathologic flow in the venous system, leading to cesarean section. The donor fetus died 12 h after delivery because of myocardial decompensation. The recipient did very well and was discharged 8 weeks later from the neonatology unit. CONCLUSION: This atypical course shows the importance of serial sonographic monitoring in pregnancies with TTTS.

Does 3-D sonography bring any advantage to noninvasive breast diagnostics?

The aim of this prospective trial was to evaluate if 3-D ultrasound (US) brings any advantage to breast diagnostics. A total of 65 women with breast lesions (42 malignant, 23 benign) were examined preoperatively with 2-D and 3-D US. The impact of the use of the 3-D coronal plane for the visualization of the infiltrative zone in comparison to 2-D US was evaluated. Additionally, 3-D surface imaging and volumetry were performed. The coronal plane was of benefit when the infiltrative zone was unclear (6 of 8 cases) or not visible (17 of 39 cases; 43.6%) using 2-D imaging. The surface mode was advantageous for imaging complex structures (e.g., a multinodular fibroadenoma). Volumetry yielded a highly significant correlation between 2-D and 3-D US. 3-D US of breast lesions as adjunct to 2-D sonography can offer a better assessment of the infiltrative zone. Moreover, it enables accurate documentation of data.
