OBJECTIVES:To evaluate the performance of fetal intelligent navigation echocardiography (FINE) applied to spatiotemporal image correlation (STIC) volumes in generating 3 specific abnormal cardiac views (left ventricular outflow tract, right ventricular outflow tract, and 3-vessel and trachea) used to screen for d-transposition of the great arteries (d-TGA). METHODS:In this prospective study, 1 or more STIC volumes were obtained from the 4-chamber view in 34 second- and third-trimester fetuses with d-TGA. Each appropriate STIC volume was evaluated by STICLoop (Samsung Medison, Seoul, Korea) before applying the FINE method. One optimal volume per fetus was selected by observers. The visualization rates of the 3 specific abnormal cardiac views of d-TGA and their diagnostic elements were calculated, and the reliability between 2 observers was verified by the intraclass correlation coefficient. RESULTS:Fetal intelligent navigation echocardiography applied to STIC volume data sets of fetuses with d-TGA successfully generated the 3 specific abnormal cardiac views in the following manner for 2 observers: 75.0% (n = 21) for the left ventricular outflow tract, 89.2% (n = 25) for the right ventricular outflow tract, and 85.7% (n = 24) for the 3-vessel and trachea view. Twenty-four (85.7%) of the STIC volume data sets showed 2 or 3 of the abnormal cardiac views. The interobserver intraclass correlation coefficients between the 2 observers ranged from 0.842 to 1.000 (95% confidence interval), indicating almost perfect reliability for the 2 observers. CONCLUSIONS:In cases of d-TGA, the FINE method has a high success rate in generating 3 specific abnormal cardiac views and therefore can be performed to screen for this congenital defect.


目的: 评价胎儿智能导航超声心动图 (FINE) 应用于时空图像相关 (STIC) 体积在产生 3 个特定异常心脏视图 (左心室流出道,右心室流出道、 3 血管和气管),用于筛选大动脉 d-转位 (d-TGA)。 方法: 在这项前瞻性研究中,从 34 例 d-TGA 孕中期和孕晚期胎儿的 4 腔视野中获得 1 个或更多的 STIC 体积。在应用精细方法之前,通过 stickloop (三星 Medison,韩国首尔) 评估每个合适的 STIC 体积。由观察者选择每个胎儿一个最佳体积。计算 d-TGA 的 3 个特定异常心脏视图及其诊断元件的显影率,并通过组内相关系数验证 2 个观察者之间的可靠性。 结果: 胎儿智能导航超声心动图应用于 d-TGA 胎儿的 STIC 容积数据集,成功地为 2 名观察者以以下方式生成了 3 个特定的异常心脏视图: 75.0% (n = 21) 对于左心室流出道,右室流出道为 89.2% (n = 25),85.7%(N = 24) 用于 3 血管和气管视图。STIC volume 数据集的 24 个 (85.7%) 显示了 2 或 3 个异常心脏视图。2 名观察者之间的观察者间组内相关系数范围为 0.842 至 1.000 (95% 置信区间),表明 2 名观察者几乎完全可靠。 结论: 在 d-TGA 病例中,FINE 方法在产生 3 个特定的异常心脏视图方面成功率高,因此可以进行筛查这种先天性缺陷。

METHODS:BACKGROUND:Ultrasound has been demonstrated to accurately diagnose rectal deep endometriosis (DE) and pouch of Douglas (POD) obliteration. The role of ultrasound in the assessment of patients who have undergone surgery for rectal DE and POD obliteration has not been evaluated. AIM:To describe the transvaginal ultrasound (TVS) findings of patients who have undergone rectal surgery for DE. MATERIALS AND METHODS:An observational cross-sectional study at a tertiary care centre in Sydney, Australia between January and April 2017. Patients previously treated for rectal DE (low anterior resection vs rectal shaving/disc excision) were recruited and asked to complete a questionnaire on their current symptoms. On TVS, POD state and rectal DE were assessed. Correlating recurrence of POD obliteration and/or rectal DE to surgery type and symptoms was done. RESULTS:Fifty-six patients were contacted; 22/56 (39.3%) attended for the study visit. Average interval of surgery to study visit was 52.8 ± 24.6 months. Surgery type breakdown was as follows: low anterior resection (56%) and rectal shaving/disc excision (44%). The prevalence of POD obliteration was 16/22 (72.7%) intraoperatively and 8/22 (36.4%) at study visit, as per the sliding sign. Nine patients (39.1%) had evidence on TVS of recurrent rectal DE. Recurrence of POD obliteration and rectal DE was not associated with surgery type or symptomatology. CONCLUSION:Despite surgery for rectal DE, many patients have a negative sliding sign on TVS, representing POD obliteration, and rectal DE. Our numbers are too small to correlate with the surgery type or their current symptoms.

METHODS::Minimally invasive surgery for complex endometriosis requires preoperative planning that intimately connects the gynecologic surgeon to the radiologist. Understanding the surgeon's perspective to endometriosis treatment facilitates a productive relationship that ultimately benefits the patient. We examine minimally invasive surgery for endometriosis and the key radiologic information which enable the surgeon to successfully negotiate patient counseling, preoperative planning, and an interdisciplinary approach to surgery.

METHODS:STUDY OBJECTIVE:Prior research collectively shows that endometriosis is inversely related to women's adiposity. The aim of this study was to assess whether this inverse relationship holds true by disease severity and typology. DESIGN:Cross sectional study among women with no prior diagnosis of endometriosis. SETTING:Fourteen clinical centers in Salt Lake City, Utah and San Francisco, California. PATIENTS:Four hundred and ninety five women, ages 18-44 years, were enrolled in the operative cohort of the Endometriosis, Natural History, Diagnosis, and Outcomes (ENDO) Study. INTERVENTIONS:Gynecologic laparoscopy/laparotomy, regardless of clinical indication. MEASUREMENTS AND MAIN RESULTS:Participants underwent anthropometric assessments, body composition, and body fat distribution ratios before surgery. Surgeons completed a standardized operative report immediately after surgery to capture revised ASRM staging (I to IV) and typology of disease (superficial [SE], ovarian endometrioma [OE], and deep infiltrating endometriosis [DIE]). Linear mixed models, taking into account within-clinical-center correlation were used to generate least square means (95% confidence intervals) to assess differences in adiposity measures by endometriosis stage (no endometriosis, I-IV) and typology (no endometriosis, SE, DIE, OE, OE + DIE) adjusting for age, race/ethnicity, and parity. While the majority of confidence intervals were wide and overlapping, three general impressions emerged: 1) women with versus without incident endometriosis had the lowest anthropometric/body composition indicators; 2) women with stage I or IV had lower indicators compared to women with stage II or III; and 3) women with OE and/or DIE tended to have the lowest indicators, while women with SE had the highest indicators. CONCLUSION:Our research highlights that the relationship between women's adiposity and endometriosis severity and typology may be more complicated than prior research indicates.
