目的 探讨实时超声引导微波消融术治疗子宫腺肌瘤的临床应用。方法 选取2015年1月～2019年1月收入我院子宫腺肌瘤患者37例为研究对象。采用超声造影评价患者的腺肌瘤消融率,常规超声评价瘤体缩小率。采用临床疗效评定标准来评价患者临床症状改善情况。结果 痛经改善率为78.9%(15/19),月经失调改善率为42.9%(9/21),贫血改善率为55.6%(10/18)。超声造影显示仅3例出现消融不完全,消融有效率为91.9%,术后行补充消融治疗,37例局限性子宫腺肌瘤平均消融率均达90%以上。与治疗前比较,治疗后3、6、12个月患者瘤体缩小率分别为60.8%、78.1%、93.1%,差异有统计学意义(P0.05)。与治疗前比较,治疗后临床症状有改善。结论实时超声引导微波消融术治疗子宫腺肌瘤患者,能够减小腺肌瘤体积,且能够明显改善患者临床症状,为子宫肌瘤患者提供新的治疗手段。     

Ultrasound-Guided Hydraulic Release Associated With Corticosteroids in Radial Tunnel Syndrome: Description of Technique and Preliminary Clinical Results

The aim of this study was to describe a perineural ultrasound-guided infiltration technique for management of radial tunnel syndrome and to report its preliminary results in 54 patients. A mixture of a saline solution, a local anesthetic, and a corticosteroid solution was infiltrated in the perineural region at the arcade of Frohse. Pain was reported in 100% of patients before the procedure versus 1.9% after the procedure. Scratch collapse and Cozen test results were positive in 98.1% and 66.7% of patients before infiltration, respectively, versus 5.6% and 9.2% after infiltration. All variables had statistically significant differences between preprocedure and postprocedure evaluations (P < .01).     

超声造影联合血清CEA、CA72-4对卵巢良恶性肿瘤鉴别诊断的价值

目的:探讨超声造影联合血清癌胚抗原（CEA）、糖类抗原72-4（CA72-4）对卵巢良恶性肿瘤鉴别诊断的价值。方法:选取2017年1月至2018年6月本院肿瘤科收治的128例卵巢肿瘤患者进行研究，进行超声造影和血清CEA、CA72-4水平检测，观察超声造影、CEA、CA72-4及联合检测对卵巢良恶性肿瘤鉴别诊断的价值。结果:在良性肿瘤组中超声造影符合率为72.92%，恶性肿瘤组中超声造影符合率为75.00%，两组比较差异无统计学意义（P>0.05）；恶性肿瘤组患者血清CEA、CA72-4水平高于良性肿瘤组，两组比较差异有统计学意义（P<0.05）；恶性肿瘤组超声造影、CA72-4检测阳性率均高于良性肿瘤组（P<0.05），两组血清CEA检测阳性率比较差异无统计学意义（P>0.05），三者联合检测阳性率高于单项指标检测（P<0.05）；通过ROC曲线分析显示，CEA的AUC为0.644，诊断灵敏度为31.25%，特异性为82.29%，CA72-4的AUC为0.702，诊断灵敏度为40.63%，特异性为79.17%，二者联合检测的AUC为0.785，诊断敏感性为56.25%，特异性为73.96%；三项指标单独检测，超声造影检测的灵敏度、阳性预测率、阴性预测率、诊断准确度及误诊率最高，CEA检测的特异性、漏诊率最高，三者联合检测的灵敏度、特异性、阳性预测率、阴性预测率、诊断准确度最高，漏诊率、误诊率最低。结论:超声造影联合血清CEA、CA72-4检测较单独检测诊断效能高，对卵巢良恶性肿瘤鉴别诊断有较高参考价值。     

血清学检测联合前列腺超声造影对老年患者前列腺癌的诊断价值分析

目的分析血清前列腺特异性抗原(PSA)检查联合超声造影诊断老年前列腺癌的价值。方法选取2016年4月至2018年12月湖北钟祥市中医院诊治的50例前列腺癌患者作为研究对象。将这50例患者设为前列腺癌组,另将50例非前列腺癌患者设为非前列腺癌组。所有患者均行超声造影检查和血清PSA检查。对比前列腺癌组与非前列腺癌组年龄、前列腺体积、超声造影参数(强度减半时间、绝对增强强度、峰值强度、基础强度、加速时间、达峰时间、显影时间);对比两组血清游离PSA(f-PSA)、血清总PSA(T-PSA)、游离前列腺特异抗原/前列腺特异抗原比值(f/T-PSA)、PSA密度(PSAD);分析不同病理类型患者血清PSA水平分布情况;经ROC曲线评估血清PSA、超声造影在该病中的诊断价值。结果①与非前列腺癌组相比,前列腺癌组强度减半时间、加速时间、达峰时间、显影时间均更短,且差异具有统计学意义(P<0.05)。②前列腺癌组患者T-PSA、PSAD组水平均较非前列腺癌组高,差异具有统计学意义(P<0.05)。③结节型和隐匿性血清PSA<4ng/mL率最高,弥散浸润伴结节型>100ng/mL最高,不同病理分型的前列腺癌患者血清PSA水平分布差异具有统计学意义(P<0.05)。④超声造影参数中仅达峰值时间、显影时间的ROC曲线下面积超过0.5。血清PSAD、T-PSA联合达峰值时间、显影时间诊断该病的ROC曲线下面积为0.924。结论血清PSAD、T-PSA联合超声造影能提高老年前列腺癌诊断价值,其中血清PSA能辅助疾病类型鉴别。     

Gastric emptying of carbohydrate drinks in term parturients before elective caesarean delivery: an observational study

BackgroundPre-operative carbohydrate (CHO) drinks have shown some benefits peri-operatively and have been incorporated into many Enhanced Recovery after Surgery (ERAS) programmes. We assessed the gastric emptying of pre-operative CHO drinks prior to elective caesarean delivery using ultrasonography.MethodsAfter a standard overnight fast, non-labouring pregnant women awaiting elective caesarean delivery underwent a standardised gastric ultrasound assessment at baseline and then every 20 min for 2 h after consuming 400 mL of a CHO drink. The gastric emptying was determined at each time-point both qualitatively and quantitatively. The primary outcome was the time taken for participants to return to a qualitative fasted Perlas grade of 0 or 1.ResultsThe gastric emptying of 40 participants was analysed. At baseline, all patients had a qualitative grade of either 0 or 1. All patients had returned to either grade 0 or 1 by 100 min. At 120 min the antral right lateral decubitus (RLD) cross-sectional area (CSA) was 8.03 cm² (95th percentile; 95% CI 7.4 to 8.3 cm²) and gastric volume per kg was 1.57 mL/kg (95th percentile; 95% CI 1.4 to 2.2). At 120 min there was no statistically significant difference from baseline for the RLD CSA (P=0.38) or gastric volume per kg (P=0.27).ConclusionsThe gastric emptying of this cohort of pregnant women suggests that 400 mL of a CHO drink can be safely consumed up to two hours before elective surgery. This study can help inform future peri-operative fasting guidelines for pregnant patients.
