概括
计算机断层扫描对身体的分歧 (CTBD) 在机器人支气管镜检查中很常见,病变往往比计划更近. 这种位移没有影响诊断产量,但意识是安全的关键.
科学领域:
- 肺部病理学 肺部病理学
- 医疗成像医学成像
- 机器人手术 机器人手术
背景情况:
- 形状感应机器人支气管镜 (ssRAB) 的诊断准确度受到计算机断层扫描对身体差异 (CTBD) 的影响.
- 虚拟和实际病变位置之间的差异CTBD,在ssRAB期间对其流行率,类型,影响和决定因素的研究不足.
- 这项研究旨在在束计算机断层扫描 (CBCT) 引导的ssRAB中量化CTBD,并确定导致的因素.
研究的目的:
- 在形光束计算机断层扫描 (CBCT) 引导的形状感应机器人支气管 (ssRAB) 过程中量化计算机断层扫描对身体差异 (CTBD).
- 在ssRAB程序中识别导致CTBD的因素.
- 评估CTBD对肺病变采样诊断产量的影响.
主要方法:
- 对接受移动CBCT引导ssRAB进行肺病变采样的患者的前性策划数据库的分析.
- 主要结果测量:在手术前CT和手术内CBCT之间,目标位移的距离和向量.
- 多变量逻辑回归分析,以确定目标病变位移的独立预测因素.
主要成果:
- 在70名参与者中,在81个向病变中的67%发生了移位 (CTBD).
- 在78%的位移病例中,ssRAB导管比预期更近 (向前位移),其中46%的病变超出预期.
- 穿越≥7个气道世代独立地与目标病变的位移有关;在位移和无位移的病例之间,诊断产量没有显著差异.
结论:
- 计算机断层扫描对身体的分歧 (CTBD) 是导航支气管镜检查过程中常见的现象,特别是在外围肺病变中.
- 支气管镜医生必须预测病变的移位,并利用手术内成像来减轻对采样和并发症的潜在影响.
- 尽管频繁地移位,但ssRAB的诊断产量在本研究中没有受到影响.

Endoscopic Studies I: Bronchoscopy and Thoracoscopy
500
Endoscopy is a non-surgical medical technique used to examine a person's internal organs and vessels. This lesson will focus on two types of endoscopic studies: bronchoscopy and thoracoscopy.
Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...

Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy
357
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...

Endoscopic Procedures III: Video Capsule Endoscopy
688
Capsule endoscopy, or wireless or video capsule endoscopy, is a diagnostic procedure for examining the entire gastrointestinal tract. Patients swallow a capsule about the size of a vitamin tablet. The capsule is equipped with a transmitter, a battery, an LED light source, and a color video camera to capture images throughout the gastrointestinal tract. This procedure is particularly useful for diagnosing conditions such as Crohn's disease, ulcerative colitis, tumors, polyps, ulcers,...
