加味大承气汤和硫酸镁联合肠道准备对大肠超声内镜检查的应用价值

目的根据大肠EUS检查对肠道准备的要求,选择肠道准备药物对肠道清洁程度、肠道清洁范围和肠道准备药物的可行性和安全性进行初步评价。方法181例常规大肠镜检查者肠道准备前随机对照非盲法分A组(大承气汤)、B组(硫酸镁)、C组(番泻叶)和D组(联合A组与B组)。常规大肠镜检查评估肠道清洁程度(甲～丁级)和清洁范围(0～4度),服药后不良反应的观察。结果D组甲级肠道清洁程度最理想95.7%,依次B组34.8%、A组31.1%和C组22.7%(P<0.01)。肠道清洁范围最大为D组93.5%,明显高于B组19.6%、A组11.1%、C组6.8%(P<0.01)。C组的不良反应明显高于A组、B组、D组(P<0.01)。C组的恶心呕吐与A组比较有显著性差异(P<0.05)。结论加味大承气汤和硫酸镁联合肠道准备,不论在肠道清洁程度和清洁范围方面,还是在服药后的不良反应方面,均已达到大肠EUS检查的要求。

大肠双重超声造影在结直肠病变中的诊断价值

目的:探讨大肠双重超声造影在结直肠病变诊断及结直肠癌TN分期中的临床应用价值。方法:回顾性选取2019年11月至2022年12月于某院收治的大肠双重超声造影结果阳性的479例患者的临床资料。以病理结果为金标准,统计大肠双重超声造影诊断结直肠病变及结直肠癌TN分期的分布情况,分析大肠双重超声造影诊断结直肠癌TN分期的临床诊断效能,并应用1VSRest策略绘制T、N分期模型诊断结直肠癌的ROC曲线。采用SAS 9.4统计学软件对数据进行分析。结果:纳入的479例患者中,病理诊断和超声诊断一致例数为462例,符合率为96.5%;结直肠癌427例,占比89.1%。在结直肠癌T1、T2、T3、T4a、T4b分期中,大肠双重超声造影诊断的准确率分别为96%、82%、63%、79%、97%,准确率的微平均值为83%。在结直肠癌N0、N1、N2分期中,大肠双重超声造影诊断的准确率分别为62%、68%、80%,准确率的微平均值为70%。T分期模型诊断结直肠癌的AUC微平均值为0.92,宏平均值为0.84;N分期模型诊断结直肠癌的AUC微平均值为0.88,宏平均值为0.85。结论:大肠双重超声造影是诊断结直肠病变的有效方法,为结直肠癌患者术前TN分期提供了重要的参考价值。

大肠B超检查与双重气钡造影的对照

60例大肠B超检查结果与X线双重气钡造影进行对照,并经纤维结肠镜或手术病理证实。两者符合率较高。无明显差异,大肠B超的特点在能够清晰地显示肠壁的层次、病变浸润程度、周围组织或脏器受累情况。它弥补了双重造影和纤维结肠镜检查的不足,三者相互补充可提高大肠疾病诊断的可靠性。

液体灌注下B超诊断大肠内外病变92例分析

我院自1993年1月～1994年5月,应用上海长海医院提供的超声显像液加温开水灌注大肠的方法,对92例有消化道症状或腹部有肿块的病人进行腹部B超检查(简称大肠B超检查),取得了良好的效果,现报告如下。

炎症性肠病诊断中大肠充盈超声检查技术应用的价值

炎症性肠病是一种慢性非特异性肠道炎症性疾病,包括溃疡性结肠炎和crohn病。目前,炎症性肠病的病因尚不明确。近年来,大肠癌的发病率呈现逐年上升的趋势。在炎症性肠病的诊断中,大肠充盈超声检查技术因其独特的优越性在临床得到了日益广泛的应用[1]。本研究对作者医院近两年来收治的50例炎症性肠病患者的临床资料进行了回顾性分析,探讨了炎症性肠病诊断中大肠充盈超声检查技术应用的价值,现报告如下。

Cardiac metastasis from colorectal cancer:A case report

The heart is an unusual site of metastasis from any malignancy. We report a case of cardiac metastasis from colorectal cancer. A 70-year-old woman was referred with a presumptive diagnosis of sigmoid colon cancer with cardiac myxoma. Two-dimensional echocardiography showed a 4 cm x 4.5 cm mobile mass on the lateral right atrial wall, and computed tomography revealed a low attenuated Iobulating mass in the right atrium. The patient underwent anterior resection for sigmoid colon cancer （T4N2）. Thereafter, she experienced progressive shortness of breath. Therefore, a cardiac operation was performed 2 wk after the colorectal operation. Histological examination revealed adenocarcinoma, which was identical to the primary lesion. Although two- dimensional echocardiography has become the diagnostic test of choice for detecting cardiac tumors, in patients with colorectal cancer showing a cardiac mass, further diagnostic evaluation such as a magnetic resonance imaging might be necessary.

Influence of Ultrasonic on Broken Effect of Foodborne Polluting Strains

[ Objective] The aim was to study on influence of ultrasonic on broken effect of foodborne polluting strains. [Method ] Escherichia coli, Staphylococcus aureus, and Aspergillus niger in different concentrations were tested in different ultrasonic powers and times for the broken effects.[ Result ] Eschedchia coil and Staphylococcus aureus were more sensitive to ultrasonication and the broken rates were as high as 96%. Aspergillus niger, however, was not so sensitive and the broken rate was only about 40%. The optimum parameters, including ultrasonic power, ultrasonic time and OD, of Escherichia coli were 600 W, 14 rain and 0.997, of Staphylococcus aureus were 600 W, 15 min and 1.440, and of Aspergillus ni- ger were 700 W, 20 min and 0.893, respectively. [ Conclusion] The research provided references for application of ultrasonic technology in food sterilization.
