Is Ultrasound a Reliable and Reproducible Method for Assessing Adnexal Masses in Pregnancy? A Systematic Review.

In this study, we aimed to systematicallyreview the current evidence regarding the diagnostic accuracy of ultrasound in assessing adnexal masses in pregnancy. The Cochrane Register of Controlled Trials, PubMed, and EMBASE databases were searched for all types of clinical studies that utilised ultrasound for the diagnosis of adnexal masses in pregnancy. Only studies that used outcome measures of either histological diagnosis or significant regression of the adnexal mass on imaging follow-up were included. The quality of each study was assessed for risk of bias. The diagnostic performance of ultrasound in each study type was calculated, along with the pooled diagnostic performance of ultrasound in differentiating benign from malignant masses. The initial search yielded 4,915 articles, of which 2,547 qualified for abstract screening. A total of 83 articles were included in this review, including one prospective cohort study, six retrospective observational studies, seven case series, and 69 case reports. In the included studies, the total number of adnexal masses was 559. The mean patient age was 29.2 years (95% confidence interval [CI]: 28.7-29.7), with a mean gestational age at diagnosis of 13.8 weeks (95% CI: 13.2-14.4). The mean quality assessment score was 75%. The International Ovarian Tumour Analysis Simple Rules were used in two articles, whereas subjective impression was used in the remaining 81 articles. The most frequently diagnosed mass was a simple or physiological cyst (35%). The prevalence of malignancy in the entire sample was 46/559 (8%; 95% CI: 34-61%). The overall pooled sensitivity, specificity, positive likelihood ratio, and negative likelihood ratio of ultrasound in detecting ovarian malignancy were 64% (95% CI: 30-88%), 88% (95% CI: 64-97%), 5.6 (95% CI: 1.2-25.4), and 0.4 (95% CI: 0.15-1), respectively. In conclusion, currently, there is a lack of high-quality prospective studies to guide the management of adnexal masses in pregnancy. Ultrasound appears to have an adequate accuracy in differentiating benign from malignant masses; however, more research is required to assess the role of ultrasound models, rules, and subjective assessment in pregnancy compared to non-pregnant women.

Early oocyte denudation does not compromise ICSI cycle outcome: a large retrospective cohort study.

This retrospective cohort study of 2051 consecutive fresh non-donor intracytoplasmic sperm injection (ICSI) cycles investigated whether time from oocyte retrieval to denudation, precisely measured and recorded by an operator-independent automated radiofrequency-based system, affected cycle outcome. ICSI cycles were divided into two groups: group I (denudation within <2 h of oocyte retrieval, n = 1118) and group II (denudation 2-5 h after oocyte retrieval, n = 933). Univariate analysis by two-sample t-test or Mann-Whitney test was used, as appropriate. Both groups were comparable with regards to mean number of oocytes retrieved and fertilized normally after ICSI. The mean number of embryos transferred and surplus embryos cryopreserved at the blastocyst stage were similar. There was no significant difference in fertilization, embryo implantation, pregnancy, clinical pregnancy or live birth rates between the groups. Analysis of group I ICSI outcome after subdivision into immediate (up to 30 min) and early (31-119 min) denudation showed no statistically significant differences between the two subgroups. In conclusion, early oocyte denudation within <2 h after retrieval does not appear to compromise ICSI cycle outcome, permitting more efficiency and flexibility in scheduling laboratory workload. As this was a retrospective observational study, further prospective studies are required to confirm the findings.

Effect of male body mass index on assisted reproduction treatment outcome: an updated systematic review and meta-analysis.

Men with a body mass index (BMI) of 30 or over are more likely to have reduced fertility and fecundity rates. This systematic review and meta-analysis evaluated the effect of male BMI on IVF and intracytoplasmic sperm injection (ICSI) outcome. An electronic search for published literature was conducted in MEDLINE and EMBASE between 1966 and November 2016. Outcome measures were clinical pregnancy rates (CPR) and live birth rates (LBR) per IVF or ICSI cycle. Eleven studies were identified, including 14,372 cycles; nine reported CPR and seven reported LBR. Pooling of data from those studies revealed that raised male BMI was associated with a significant reduction in CPR (OR 0.78, 95% CI 0.63 to 0.98, P = 0.03) and LBR (OR 0.88, 95% CI 0.82 to 0.95, P = 0.001) per IVF-ICSI treatment cycle. Male BMI could be an important factor influencing IVF-ICSI outcome. More robust studies are needed to confirm this conclusion using standardized methods for measuring male BMI, adhering to the World Health Organization definitions of BMI categories, accounting for female BMI, IVF and ICSI cycle characteristics, including the number of embryos transferred and embryo quality, and use the live birth rate per cycle as primary outcome.

A multicenter prospective external validation of the diagnostic performance of IOTA simple descriptors and rules to characterize ovarian masses.

OBJECTIVES: To evaluate the diagnostic performance of the IOTA (International Ovarian Tumor Analysis group) (clinically oriented three-step strategy for preoperative characterization of ovarian masses when ultrasonography is performed by examiners with different background training and experience. METHODS: A 27-month prospective multicenter cross-sectional study was performed. 36 level II ultrasound examiners contributed in three UK hospitals. Transvaginal ultrasonography was performed using a standardized approach. Step one uses simple descriptors (SD), step two ultrasound simple rules (SR) and step three subjective assessment of ultrasound images (SA) by examiners. The final outcome was findings at surgery and the histological diagnosis of surgically removed masses. RESULTS: 1165 women with adnexal masses underwent transvaginal ultrasonography, 301 had surgery. Prevalence of malignancy was 31% (n=92). SD were able to classify 46% of the masses into benign or malignant (step one), with a sensitivity of 93% and specificity of 97%. Applying SD followed by SR to residual unclassified masses by SD enabled 89% of all masses (n=268) to be classified with a sensitivity 95% of and specificity of 95%. SA was then used to evaluate the rest of the masses. Compared to the risk of malignancy index (RMI), the sensitivity and specificity for the three-step (SD+SR+SA) strategy were 93% (95% CI: 86-97%) and 92% (95% CI: 87-95%) vs. 72% (95% CI: 62-80%) and 95% (95% CI: 91-97%) for RMI, respectively. CONCLUSION: The IOTA three-step strategy shows good test performance on external validation in the hands of ultrasonography examiners with different background training and experience. This performance is considerably better than the RMI.

Is there a role for transplantation in gynecologic oncology? Autotransplantation and other lessons.

We describe an exciting and novel surgical option, which may be used to treat formerly unresectable masses. This process is commonly referred to as autotransplantation (AuTn), and it combines the advances in transplant medicine and applies them to surgical oncology. The idea behind AuTn is the removal of the cancerous organ(s) to allow complete anatomic resection of the tumor mass, with consequent anastomotic reimplantation or AuTn of the now macroscopically tumor-free organ back into the patient. Autotransplantation has been used to remove large fibromatosis and desmoid tumors as well as malignant tumors. Our belief is that using lessons learned from the field of transplantation, AuTn can be applied in gynecologic oncology.

Obstructive jaundice due to autoimmune cholangiopathy.

A 59-year-old man presented with upper abdominal pain, cholestasis and radiological evidence of common hepatic duct hilar stricture which was suggestive of cholangiocarcinoma. The patient initially underwent percutaneous drainage and a laparotomy. No evidence of malignancy was identified. He was noted to have retroperitoneal fibrosis, which was confirmed on histology. The combination of cholangiopathy and retroperitoneal fibrosis suggested an underlying autoimmune process. Although the investigations did not show any evidence of IgG4 related disease, the combination of a cholangiopathy and retroperitoneal fibrosis is in keeping with autoimmune cholangiopathy and a steroid regimen was commenced. Our patient is now symptom-free with no further episodes of cholangitis. He has commenced azathioprine to maintain long term remission.
