概括
高分辨率直肠测量仪 (HR-ARM) 和常规直肠测量仪 (C-ARM) 在压力测量方面显示出极好的一致性. 然而,当使用当前规范值时,诊断一致性很差,需要特定于设备的范围来准确解释.
科学领域:
- 胃肠病学 胃肠病学
- 结肠直肠手术 结肠直肠手术
- 诊断成像 诊断成像 诊断成像
背景情况:
- 高分辨率直肠测量仪 (HR-ARM) 越来越多地被采用,经常取代传统的直肠测量仪 (C-ARM).
- 现有研究报告了压力测量的强烈相关性,但在各设备的规范值存在显著差异.
- 这种差异凸显了需要直接比较同一患者队列中从C-ARM和HR-ARM中获得的测力参数的必要性.
研究的目的:
- 为了比较C-ARM和HR-ARM之间的力度参数.
- 评估两种计量法之间的定量压力测量和诊断分类的一致性.
- 评估使用HR-ARM的现有规范值的临床影响.
主要方法:
- 连续50名患者接受了同一个检查员的C-ARM和HR-ARM.
- 对于连续变量 (例如,静止和挤压压力) 使用类内相关系数.
- 卡帕系数评估对类别变量 (例如功能门长度,诊断类别) 的一致性.
主要成果:
- 观察到C-ARM和HR-ARM之间的休息和挤压压力有很好的一致性.
- 对于功能性门通道长度而言,协议很差.
- 诊断一致性在门声和失能标志物方面相当或适度,但在使用当前规范值时,对直肠放松和直肠内推进不佳.
结论:
- 在量化休息和挤压压力方面,C-ARM和HR-ARM表现出了很好的一致性.
- 当应用当前的规范值时,诊断一致性显著下降,这表明临床解释的一致性很差.
- 为HR-ARM建立独特的,特定于设备的参考范围对于准确的诊断和患者管理至关重要.

Assessment of the Rectum and Anus
1.1K
Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.

Urodynamic Studies: Uroflowmetry
3.4K
Uroflowmetry is a non-invasive urodynamic test designed to measure various aspects of urination, including volume, flow rate, and the time to void. This test is crucial for diagnosing and assessing conditions such as bladder outlet obstruction, bladder dysfunction, incomplete bladder emptying, incontinence, and urinary tract blockages caused by benign prostatic hyperplasia (BPH) and urethral strictures.Pre-Test Instructions:Before a uroflowmetry test, patients are typically advised to drink...
