Conjoined Twins Complicating a Dichorionic Triplet Pregnancy after Intracytoplasmic Sperm Injection: A Case Report and Review of the Literature.

Conjoined twins represent a rare type of monoamniotic twins. Ultrasound assessment during the first trimester can facilitate the diagnosis, however further assessment by colour Doppler studies, 3D imaging, fetal echocardiography and fetal magnetic resonance imaging (MRI) is usually required in order to determine the specific fetal abnormalities and to guide appropriate pregnancy management. This case report presents a rare case of conjoined twins complicating a dichorionic-diamniotic triplet pregnancy, achieved after intracytoplasmic sperm injection (ICSI) and blastocyst transfer. A 44-year-old woman was referred for chorionicity determination to our Fetal Medicine Centre due to suspicion of conjoined twins in a triplet pregnancy. Ultrasound assessment at 11 weeks demonstrated a dichorionic triplet pregnancy which was also complicated by a rare type of conjoined twins (thoracoomphalopagus) and after a successful embryo reduction a neonate of 2200 g was delivered by caesarean section at term. The accurate diagnosis and early detection of conjoined twins by a fetal medicine specialist is crucial, especially as far as multiple pregnancies with three or more fetuses are concerned.

Is computerized cardiotocography useful in monochorionic twins with selective intrauterine growth restriction?

OBJECTIVE: To assess the value of using computerized cardiotocography (cCTG) short-term variation (STV) for intrapartum monitoring in monochorionic twins (MC) complicated by selective intrauterine growth restriction (sIUGR). MATERIAL AND METHODS: All available cCTGs retrieved from computerized medical records of MC with sIUGR were retrospectively studied regarding the behavior of the STV. sIUGR was defined as intertwin estimated fetal weight (EFW) discordance of ≥20% with the abdominal circumference (AC) below the fifth percentile and/or the EFW of the smaller twin below the 10th percentile. The sIUGR classification system proposed by Gratacos et al. was used using types I-III on the basis of umbilical artery Doppler characteristics of the IUGR twin. The admission (entry) STV and final pre-delivery (last) STV values were analyzed. Cases with intrauterine demise, with structural or chromosomal abnormalities, with twin anemia polycythemia sequence (TAPS) and/or twin-to-twin transfusion syndrome (TTTS) were excluded. RESULTS: During the study period, 64 consecutive cases were managed within our department. Thirty-two cases fulfilled the inclusion criteria for analysis. Mean gestational age at assessment and at delivery was 28.4 ± 2.7 and 31.5 ± 2.2 weeks, respectively. The entry STV and last STV before delivery were not statistically different (mean IUGR STV entry: 9.3 ± 3.4 ms versus last 8 ± 2.2 ms; p = .051; mean co-twin STV entry: 9.1 ± 2.8 ms versus last 9.2 ± 3 ms; p = .87). Neither was the sIUGR-type adjusted STV. CONCLUSIONS: In MC pregnancies complicated by sIUGR, the cCTG STV does not distinguish between fetuses, nor does it show differences in cases of fetal deterioration monitored by conventional CTG.

Misoprostol vaginal insert versus misoprostol vaginal tablets for the induction of labour: a cohort study.

BACKGROUND: Misoprostol vaginal insert for induction of labor has been recently reported to be superior to dinoprostone vaginal insert in a phase III trial, but has never been compared to vaginal misoprostol in another galenic form. The aim of this study was to compare misoprostol vaginal insert (MVI) with misoprostol vaginal tablets (MVT) for induction of labor in term pregnancies. METHODS: In this retrospective cohort study we compared 200 consecutive women induced with 200-µg misoprostol 24-h vaginal insert (Misodel®) with a historical control of 200 women induced with Misoprostol 25-µg vaginal tablets (Cytotec®) every 4-6 h. Main outcomes variables included induction-to-delivery interval, vaginal delivery within 24-h, incidence of tachysystole, mode of delivery, and neonatal outcome. A subanalysis in the MVI group was performed in order to identify predictive factors for tachysistole and vaginal delivery within 24 h. RESULTS: The time from induction to vaginal delivery was 1048 ± 814 min in the MVI group and 1510 ± 1043 min in the MVT group (p < 0.001). Vaginal delivery within 24-h occurred in 127 (63.5%) patients of the MVI group and in 110 (55%) patients of the MVT group (p < 0.001). Tachysystole was more common in the MVI group (36% vs. 18%; p < 0.001). However, no significant predictors of uterine tachysystole in MVI group have been identified in crude and fully adjusted logistic regression models. Bishop score was the only predictor for vaginal delivery within 24 h (p < 0.001) in MVI group. Caesarean delivery rate (27% vs. 20%) and vaginal-operative deliveries (15.5% vs. 15.5%) did not differ significantly between the two groups. Neonatal outcomes were similar in both groups. CONCLUSIONS: MVI achieves a more vaginal delivery rate within 24 h and Tachysystole events compared to MVT. However, no differences in caesarean section, operative vaginal delivery, and neonatal outcomes are reported. No predictors of tachysistole after MVI administration have been identified. Bishop score and parity are the only predictors of vaginal delivery within 24 h after MVI administration.

The Efficacy of Fibrin Sealant Patches in Reducing the Incidence of Lymphatic Morbidity After Radical Lymphadenectomy: A Meta-Analysis.

BACKGROUND: Although pivotal in the oncological management of most tumors, radical lymphadenectomy is associated with a significant number of lymphatic complications. The aim of this meta-analysis is to evaluate the efficacy of fibrinogen sealant patches in reducing lymphadenectomy-related postoperative complications. METHODS/MATERIALS: The electronic databases PubMed, Medline, and Scopus were searched using the terms "lymphadenectomy" or "lymph node dissection" and "TachoSil," "TachoComb," or "fibrin sealant patch." Series evaluating the efficacy of fibrin-thrombin collagen sealant patches were included in the meta-analysis. RESULTS: Overall, 26 studies were retrieved through the literature search. Ten studies including 720 patients met selection criteria. The use of fibrin-thrombin sealant patches to the sole scope of reducing lymphadenectomy-related complications significantly reduced the incidence of lymphocele, symptomatic lymphocele, the need of percutaneous drainage procedures, the volume of lymph drained, and the duration of the drainage. No effect on wound and/or lymphocele infection was noted. CONCLUSIONS: This meta-analysis demonstrates that the use of fibrin-thrombin sealant patches significantly reduces the total volume of lymph drained, the duration of the drainage, the incidence of lymphocele and symptomatic lymphocele, and the need for postoperative percutaneous drainage procedures. Its use does not affect the incidence of wound or lymphocele infections.

Cervical length after cerclage: comparison between laparoscopic and vaginal approach.

PURPOSE: The aim of our study was to investigate the sonographic changes of the cervical length during pregnancy after the placement of a transvaginal cervical cerclage (TVC) or a laparoscopic abdominal cerclage (LAC) in patients with cervical insufficiency (CI). METHODS: Between January 2008 and March 2015, a retrospective analysis of all women undergoing a prophylactic laparoscopic (LAC group) or transvaginal (TVC group) cerclage due to cervical insufficiency was conducted. Nonparametric variables were analysed with the Mann-Whitney (U) test, and categorical-type outcomes were analysed with the Fisher's exact test. A p value <0.05 was considered as significant. Data analysis was performed using Prism 5 for Mac OS X. RESULTS: Thirty-eight patients were included. Of these, 18 and 20 underwent an LAC and a TVC, respectively. Mean gestational age at surgery in the LAC and TVC groups was 11.4 ± 1.6 and 17 ± 3 weeks, respectively (p < 0.05). The cervical length prior to surgery was similar among the two groups. After cerclage placement, the distance between the tape and the external cervical os differed significantly between the two groups (LAC: 31.5 ± 8.8 mm vs TVC: 13.5 ± 4.9 mm; p < 0.0001) (Fig. 1). During pregnancy, the cervical length in the TVC group showed a significant shortening (from 26.6 ± 7 mm before surgery to 13.2 ± 7 mm at 33 weeks; p < 0.0001), while in the LAC group, the cervical length remained unchanged. CONCLUSIONS: In patients with CI, LAC is associated with a better preservation of the cervical length throughout pregnancy as compared to TVC.

Laparoscopic management of ectopic pregnancies: a comparison between interstitial and "more distal" tubal pregnancies.

BACKGROUND/AIMS: Laparoscopy is an established, safe, and feasible management option for tubal pregnancies, even in women with significant hemoperitoneum. In case of interstitial pregnancy, however, a laparoscopic surgical approach is still a matter of debate. The objective of this study is to evaluate the safety and feasibility of a laparoscopic approach to interstitial pregnancies. METHODS: A total of 92 women with ectopic pregnancy who underwent a surgical management from April 2009 to August 2015 were reviewed. Clinical and surgical outcomes of confirmed interstitial pregnancies (n = 10) (IP group) were compared with those of "more distal" tubal pregnancies (n = 79) (TP group). RESULTS: Although there were no differences between the two groups in gestational age, ß-hCG values were significantly higher in the IP group (p = 0.005). All patients with IP were treated by laparoscopic wedge resection. The rate of surgical complications (p = 0.413) and subsequent MTX treatment (p = 0.531) were not significantly different between groups. Operating room (OR) time (p = 0.007) was higher in the IP than in the TP group. After stratification for the presence of hemoperitoneum this difference remained, with patients in the IP group having longer OR time (p = 0.034) and additionally higher intra-operative blood loss (EBL) (p = 0.013). On the other hand, in the absence of hemoperitoneum no differences between the two groups were observed. CONCLUSIONS: In experienced hands, the laparoscopic management of interstitial pregnancies seems to be as safe and feasible as that of other tubal pregnancies. However, it could be technically more challenging, especially in case of hemoperitoneum.

Accuracy of Sentinel Lymph Node Mapping After Previous Hysterectomy in Patients with Occult Cervical Cancer.

BACKGROUND: In patients with a diagnosis of occult cervical cancer made on a hysterectomy specimen after surgery for a benign indication, lymph node assessment is crucial to determine treatment. We aimed to compare sentinel lymph node (SLN) mapping between patients with postoperative diagnosis of occult cervical carcinoma and patients with cervical cancer and uterus in situ. METHODS: A retrospective analysis of cervical cancer patients International Federation of Gynecology and Obstetrics (FIGO) stage IA-IIA disease undergoing laparoscopic SLN mapping was performed. Patients were divided into two groups: those with a diagnosis of occult cervical cancer made on a hysterectomy specimen (group 1) and those with a diagnosis of cervical cancer and uterus in situ (group 2). Tracers used for SLN mapping included technetium-99m ((99m)Tc), blue dye, and indocyanine green. After detection and excision, the SLN was sent for frozen section analysis, and the planned surgical procedure was aborted in case of metastatic disease in favor of a chemoradiotherapeutic treatment. RESULTS: Groups 1 and 2 included 9 and 62 patients, respectively. Clinicopathologic characteristics were similar among the two groups. Overall and bilateral detection rates were 66.6 and 33.3 and 95.1 and 87 % in groups 1 and 2, respectively (p < 0.05). No false-negative SLNs were identified in either group, with a negative predictive value of 100 %. CONCLUSIONS: SLN mapping in occult cervical cancer patients has lower detection rates compared to patients with uterus in situ. In these patients, proper management of their disease has already failed before diagnosis, and additional mistakes may definitely compromise attempts at cure.

Laparoscopic Ultrasound-Guided Repair of Uterine Scar Isthmocele Connected With the Extra-Amniotic Space in Early Pregnancy.

We present a video of an ultrasound-guided laparoscopic surgical management of a large uterine scar isthmocele connected with the extra-amniotic space in early pregnancy. A case of a pregnant patient who was diagnosed with a large isthmocele connected with the extra-amniotic space on routine ultrasound at 8 weeks of gestational age is presented. The uterine defect was successfully sutured laparoscopically under ultrasound guidance. The pregnancy continued uneventfully, and a healthy baby was delivered via cesarean section at 38 weeks gestational age.

Laparoscopic Indocyanine Green Sentinel Lymph Node Mapping in Pregnant Cervical Cancer Patients.

We present cases of 2 pregnant patients with early-stage cervical cancer who have undergone indocyanine green (ICG) sentinel lymph node (SLN) mapping followed by laparoscopic SLN biopsy, pelvic lymphadenectomy, and cervical conization. Eight milliliters of ICG were injected in the 4 quadrants of the cervix after having obtained an adequate pneumoperitoneum and having inspected the abdominal cavity. SLNs were identified in both hemipelvises in both patients. In the final pathologic analysis, both SLNs and non-SLNs were negative for metastatic disease. No adverse events from ICG injection were recorded. ICG SLN mapping seems to be feasible in pregnant cervical cancer patients.

Hepatic resection during cytoreductive surgery for primary or recurrent epithelial ovarian cancer.

PURPOSE: Surgical cytoreduction remains a cornerstone in the management of patients with advanced and recurrent epithelial ovarian cancer. Parenchymal liver metastases determine stage VI disease and are commonly considered a major limit in the achievement of an optimal cytoreduction. The purpose of this manuscript was to discuss the rationale of liver resection and the morbidity related to this procedure in advanced and recurrent ovarian cancer. METHODS: A search of the National Library of Medicine's MEDLINE/PubMed database until March 2015 was performed using the keywords: "ovarian cancer," "hepatic," "liver," and "metastases." RESULTS: In patients with liver metastases, hepatic resection is associated with a similar prognosis as stage IIIC patients. The length of the disease-free interval between primary diagnosis and occurrence of liver metastases, as well as residual disease after resection, is the most important prognostic factors. In addition, the number of liver lesions, resection margins, and the gynecologic oncology group performance status seem to play also an important role in determining outcome. CONCLUSIONS: In properly selected patients, liver resections at the time of cytoreduction increase rates of optimal cytoreduction and improve survival in advanced-stage and recurrent ovarian cancer patients.

Placental plasticity in monochorionic twins: Impact on birth weight and placental weight.

INTRODUCTION: The knowledge about adaptive mechanisms of monochorionic placentas to fulfill the demands of two instead of one fetus is largely speculative. The aim of our study was to investigate the impact of chorionicity on birth weight and placental weight in twin pregnancies. METHODS: Forty Monochorionic (MC) and 43 dichorionic (DC) twin pregnancies were included in this retrospective study. Individual and total (sum of both twins) birth weights, placental weights ratios between placental and birth weights and observed-to-expected (O/E)-ratios were calculated and analyzed. Additionally, we investigated whether in twin pregnancies placental and birth weights follow the law of allometric metabolic scaling. RESULTS: MC pregnancies showed higher placental O/E-ratios than DC ones (2.25 ± 0.85 versus 1.66 ± 0.61; p < 0.05), whereas the total neonatal birth weight O/E-ratios were not different. In DC twins total placental weights correlated significantly with gestational age (r = 0.74, p < 0.001), but not in MC twins. Analysis of deliveries ≤32 weeks revealed that the placenta to birth weight ratio in MC twins was higher than in matched DC twins (0.49 ± 0.3 versus 0.24 ± 0.03; p = 0.03). Allometric metabolic scaling revealed that dichorionic twin placentas scale with birth weight, while the monochorionic ones do not. DISCUSSION: The weight of MC placentas compared to that of DC is not gestational age dependent in the third trimester. Therefore an early accelerated placental growth pattern has to be postulated which leads to an excess placental mass particularly below 32 weeks of gestation. The monochorionic twins do not follow allometric metabolic scaling principle making them more vulnerable to placental compromise.

Doppler Ultrasound Flow Evaluation of the Uterine Arteries Significantly Correlates with Tumor Size in Cervical Cancer Patients.

PURPOSE: The aim of this present study was to evaluate the sonographic correlation between Doppler flow characteristics of the uterine arteries and tumor size in patients with cervical cancer, in order to establish a new potential marker to monitor treatment response. METHODS: This was a retrospective cohort study of 25 patients who underwent a sonographic evaluation of Doppler flow characteristics of the uterine arteries before surgery or radiochemotherapy for early and locally advanced/advanced cervical cancer, respectively, was analyzed. The primary outcome was the correlation between Doppler flow characteristics of the uterine arteries and tumor size in patients with cervical cancer. RESULTS: Median age was 49 (range 26-85) years, and mean tumor size was 40.8 ± 17 mm. A significant positive correlation was found between tumor diameter and the uterine artery end-diastolic velocity (r = 0.47, p < 0.05) as well as the peak systolic velocity (r = 0.41, p < 0.05). No correlation was found between tumor size and the pulsatility index or resistance index. CONCLUSIONS: In cervical cancer, uterine artery velocity parameters are associated with tumor size. This finding could become particularly useful in the follow-up of locally advanced cervical cancer patients undergoing radiochemotherapy or in corroborating the selection of women with more possibility of a high response rate during neoadjuvant chemotherapy before surgery.

Hypertension in pregnancy.

PURPOSE OF REVIEW: Hypertension in pregnancy contributes substantially to perinatal mortality and morbidity of both the mother and her child. High blood pressure is mainly responsible for this adverse outcome, in particular when associated with preeclampsia. Although preeclampsia is nowadays a well-known clinical-obstetrical entity, and screening for this complication has been part of routine care during pregnancy for nearly 100 years, its cause is still enigmatic. RECENT FINDINGS: Profound changes of the demographic development of our society, the worldwide rising prevalence of obesity and metabolic disorders, and progress in reproductive medicine will inevitably modify the prevalence of many medical problems in pregnancy. Complications such as gestational diabetes mellitus, chronic hypertension, and preeclampsia will rise and an interdisciplinary approach is necessary to handle these women during pregnancy and also after delivery. Indeed, it is now well established that these women and their offspring born large or small-for-gestational age are at increased risk for severe cardiovascular and metabolic complications later in life. SUMMARY: Knowledge of the pregnancy course is not only important for an obstetrician but also increasingly inevitable for the general practitioner. Recognition, classification, and adequate management of hypertensive pregnancy disorders and associated complications may considerably reduce perinatal death and morbidity.

Altered sonographic umbilical cord morphometry in early-onset preeclampsia.

OBJECTIVE: To determine whether the sonographic morphometry of the umbilical cord components is different in preeclamptic compared with healthy pregnant women. METHODS: Consecutive women admitted after 20 weeks' gestation with the diagnosis of preeclampsia and whose fetus was normally grown (cases) were included in the study. Each case was matched to a healthy pregnant woman (controls) who had ultrasonography at the same gestational age (+/- 3 days). The sonographic cross-sectional areas of the umbilical cord and umbilical vessels were obtained in all patients and plotted on reference ranges. The umbilical artery resistance index was measured in all patients with preeclampsia. RESULTS: Twenty-five preeclamptic women were enrolled. The proportion of cases with a lean (below the tenth centile) umbilical cord was higher in cases than in controls (12 of 25 versus 1 of 25, P <.001). The Wharton's jelly area was lower in cases than in controls (median 105.8 mm(2) [range 49.6-212.9 mm(2)] versus 138.7 mm(2) [79.7-226.6 mm(2)], P =.024). The umbilical vein area was less in cases than in controls (median 29.2 mm(2) [range 8.0-52.8 mm(2)] versus 37.4 mm(2) [13.8-70.8 mm(2)], P =.032). The proportion of patients with a lean umbilical cord was higher among those with early-onset preeclampsia than in those with late-onset preeclampsia (12 of 19 versus 0 of 6, P =.014). CONCLUSION: Early-onset preeclampsia frequently is associated with reduced Wharton's jelly area and umbilical vein area compared with normal pregnancy. Sonographic umbilical cord morphometry might have clinical value for prompt identification of women at risk for preeclampsia.
