概括
使用内镜超声波 (EUS) 和侧视十二指镜与狭窄带成像 (SVD + NBI) 准确的术前瘤评估对于规划内镜乳头切除术至关重要. 这些方法改善了切除能力和高风险特征的评估,超越了传统活检的局限性.
科学领域:
- 胃肠病学和内镜检查
- 在瘤学瘤学.
- 诊断成像 诊断成像 诊断成像
背景情况:
- 在选择适当的内镜乳头切除策略时,对囊瘤的术前评估至关重要.
- 目前的文献缺乏关于通过内镜超声波 (EUS) 和侧视双胞胎镜与狭窄带成像 (SVD + NBI) 识别的关键特征的全面报告.
研究的目的:
- 为了证明囊病变的理论和现实世界的管理.
- 评估预切割活检和细针吸收 (FNA) 的实施和诊断价值.
- 根据EUS和SVD+NBI识别关键特征,用于对囊瘤进行手术前评估.
主要方法:
- 连续接受EUS和SVD + NBI (2020年1月至2023年12月) 的怀疑乳头病变的患者的回顾性分析.
- 主要结果:理论与现实管理的比较,使用EUS和SVD + NBI识别腺癌,T1阶段和导管入侵的高风险特征.
- 二次结果:评估手术前活检和FNA的价值.
主要成果:
- 只有27.40%的被归类为手术治疗的患者可以被认为是内镜可切除的.
- 活检和FNA结果显示,分别在46.4%和35%的病例中,与术后发现存在不一致.
- 腺癌的高风险因素包括具有异型的突起,NBI型III,EUS大小≥3.0厘米,低声性,血液供应不良和EUS管道入侵. 尺寸≥3.0厘米和低音状态是T1和导管入侵的高风险因素. 腺癌的染色比切割值为5.35 (灵敏度为88.5%,特异性为93.0%,精度为90.8%).
结论:
- 虽然囊瘤的手术前评估是必要的,但单独的活检和FNA不足以准确诊断和管理计划.
- EUS和SVD + NBI是评估囊瘤的宝贵工具,特别是通过关注基本诊断特征来评估内镜切除能力.
- 整合EUS和SVD + NBI可以提高手术前评估的准确性,指导更有效的治疗策略.

Econometric Views, often stylized as EViews, is a package that merges statistical analysis with econometric studies. It is designed to provide tools for time series analysis, forecasting, and econometric model simulation. The software originated from MicroTSP software and has evolved significantly since its inception in 1981. The history of EViews is marked by a continuous effort to enhance its computational speed and user interface. It was initially developed for large computing systems but...

01:27Cranial Bones: Lateral View
4.5K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

01:24Revisionist Views of Adolescent and Adult Cognition
299
A revisionist approach to Jean Piaget's theory of cognitive development has brought new insights that challenge and reinterpret his established ideas. Piaget proposed that the formal operational stage, emerging in adolescence, represents the culmination of cognitive maturity. During this stage, individuals are said to develop abstract thinking, engage in systematic problem-solving, and show a form of egocentrism, believing others are as preoccupied with their behavior as they are...

01:14Cranial Bones: Superior and Posterior View
5.1K
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...

An Esophagogastroduodenoscopy (EGD) is a diagnostic procedure in which an endoscopist uses a flexible, lighted endoscope to visualize the upper gastrointestinal (GI) tract. The procedure includes visualizing the oropharynx, esophagus, stomach, and the first part of the small intestine, the duodenum.
During an EGD, the endoscope can be used to:
