概括

放射性分析显示,在患有秋症和其他食道运动障碍的患者的食道间隙中,纤维结合组织增加. 这种纤维化可能导致在这些条件下观察到的运动限制.

科学领域:

胃肠病学胃肠病学
放射学放射学是一门学科.
医学成像分析医学成像分析

背景情况:

正常的食道周静止包括在食道和隔膜之间滑动.
这种相对运动在患有食道的患者中是不存在的.

研究的目的:

通过CT放射学研究食道间隙组织特征,以查拉西亚,高幅度食道收缩 (HAEC) 和食道胃结出流阻塞 (EGJOO) 为目的.
将这些发现与正常受试者进行比较.

主要方法:

来自1221个对照组,409名阿喀拉西亚,562名EGJOO和349名HAEC患者的CT图像的放射学分析.
使用多平面旋转2D视觉化食道间隙.
在皮下脂肪组织,脊柱后部肌肉和食道间隙中确定灰度强度分布 (GSID).

主要成果:

在四组中,皮下脂肪组织或肌肉的GSID没有显著差异.
与对照组相比,在阿喀拉西亚,HAEC和EGJOO组中食道间隙的GSID平均值显著更高.
与HAEC和EGJOO患者相比,阿喀拉西亚患者的间歇性GSID更高,在患者群体中,特别是阿喀拉西亚患者中,间歇性和肌肉GSID之间的重叠更大.

结论:

升高的间隙GSID和增加的间隙肌重叠表明,患有原发性食道运动障碍 (EMD) 的患者食道间隙中纤维结合组织增加.
建议的机制:食道间隙中的纤维化限制了下食道关节 (LES) 和膜之间的轴向分离,可能导致EMD的发病.

Esophageal Strictures-I: Introduction

Esophageal Strictures-I: Introduction

Esophageal strictures involve abnormal narrowing or tightening of the esophagus. They vary in length and severity, ranging from mild constriction to complete obstruction, and are classified as benign (noncancerous) or malignant (cancerous).
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...

Barrett Esophagus-II: Clinical Manifestations and Management

Individuals with Barrett's esophagus are often asymptomatic, but they may experience symptoms commonly associated with GERD, such as heartburn and acid regurgitation. Additional symptoms can include difficulty swallowing, chest pain, unintentional weight loss, blood in the stool (which may appear black, tarry, or bloody), and episodes of vomiting.
To diagnose Barrett's esophagus, healthcare providers often recommend an endoscopy for those showing symptoms of acid reflux. The procedure...
