概括
高分辨率阳门测量 (HR-ARM) 和磁共振缺口学 (MRD) 评估骨盆底功能障碍. 这项研究发现,MRD在便秘患者中除了HR-ARM之外没有提供显著的额外诊断价值.
科学领域:
- 胃肠病学 胃肠病学
- 盆地底疾病 盆地底疾病
- 诊断成像 诊断成像 诊断成像
背景情况:
- 在患有阻塞性排便症状的患者中,经常研究疏散障碍.
- 高分辨率阳门测量 (HR-ARM) 是一个标准的,可访问的诊断工具,用于盆地功能障碍.
- 磁共振缺口学 (MRD) 是一种更先进,更难以获得的成像技术.
研究的目的:
- 为了确定磁共振缺口学 (MRD) 在患有骨盆底功能障碍的患者的诊断附加值.
- 在被诊断为便秘的患者中比较HR-ARM和MRD的发现.
- 评估MRD是否提供了超越HR-ARM的额外信息,以指导治疗建议.
主要方法:
- 一项回顾性审查确定了76名患者,他们在2020年1月至2022年5月期间接受了HR-ARM和MRD治疗便秘.
- 单变量和多变量分析比较了患有和没有异常HR-ARM结果的患者的MRD发现.
- 统计方法包括Pearson对分类变量的千平方测试和连续变量的两样样 t 测试.
主要成果:
- 在76名患者中,64.5%的人在HR-ARM上表现出异能.
- 患有HR-ARM诊断的失能症的患者在MRD上显著延长了气球和不完整的凝驱逐时间 (p < 0.001).
- 然而,HR-ARM诊断的功能失调与MRD临床显著性直肠骨 (>2厘米) 或直肠外倒的可能性显著增加并不相关.
结论:
- 对MRD的解剖学发现在HR-ARM识别的异能症患者和没有异能症患者之间是可比的.
- 在这个队列中,与HR-ARM单独相比,同时使用MRD并没有提供重要的额外诊断信息来指导治疗决策.
- 需要进一步的前性研究,以确定MRD在诊断骨盆底疾病中的附加值.

Assessment of the Rectum and Anus
402
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.

Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy
142
This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and...

Magnetic Resonance Imaging
6.9K
Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

Lower GI Series: Barium Enema
499
A Barium Enema, or a lower GI series, is a specialized radiographic examination designed to visualize the lower gastrointestinal tract, specifically the colon and rectum. This procedure is instrumental in diagnosing various conditions such as colorectal cancer, polyps, diverticulosis, and inflammatory bowel disease.
Procedure Details
The examination begins by inserting a lubricated rectal tube into the patient's rectum to administer a radiopaque barium solution. The barium flow is carefully...

Imaging Studies IV: Magnetic Resonance Imaging

Introduction:Magnetic Resonance Imaging, or MRI, can include a specialized imaging technique of the urinary system known as Magnetic Resonance Urography (MRU). This radiation-free technique uses strong magnetic fields and radio waves to produce detailed images with the help of a computer. MRU is particularly effective for visualizing fluid-filled structures like the kidneys, ureters, and bladder.Applications of MRI in the Genitourinary SystemKidneys and Ureters: MRI detects tumors, cysts,...
