概括
与内透镜气球扩张 (EBD) 相比,内透镜严格切除术 (ESt) 在克罗恩病 (CD) 解剖狭窄症中提供了更大,更持久的光线扩张. 对于CD患者来说,ESt可能是一个更有效的内镜治疗选择.
科学领域:
- 胃肠病学 胃肠病学
- 手术创新 在外科创新.
- 动物模型 动物模型
背景情况:
- 解剖管狭窄是克罗恩氏病 (CD) 患者手术后的常见并发症,通常药物管理不充分.
- 内镜气球扩张 (EBD) 和内镜严格切除术 (ESt) 是最少的侵入性选择,但对比数据有限.
- 标准化动物模型对于在受控环境中评估治疗疗效至关重要.
研究的目的:
- 为了比较EBD与EST的疗效,在一个随机的动物模型中,对CD相关的静脉缩进行了比较.
- 评估与每个内镜干预相关的长期光通能力和不良事件.
主要方法:
- 在微型猪身上创建了一种化学诱导的静脉静脉狭窄模型.
- 44只患有狭窄的动物被随机分配到EBD,EST或对照组.
- 在六个月内通过内镜测量了缩直径,结果包括直径变化和透度.
主要成果:
- EBD和ESt都增加了静脉直径,但只有ESt获得了统计学意义 (17.51mm与11.27mm基线相比;p=0.0002).
- 与EBD相比,ESt在六个月内显示了明显更大的直径增长 (6.24毫米与3.31毫米相比; p=0.042).
- 发生了三次穿孔 (两次EBD,一次ESt),全部通过内镜进行管理,没有死亡率;动物福利情况相似.
结论:
- 在这个实验模型中,ESTt的结果比EBD显著更大,更持久的光线扩大.
- 在技术上,EBD和ESt都是可行的和安全的.
- 作为一项更有效的内镜治疗纤维肌性CD的方法,ESt显得有前途,可能减少对手术的需要.

Inflammatory Bowel Disease V: Surgical Management
811
Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.
Here are some common surgical interventions for IBD:

Esophageal Strictures-II: Clinical Features and Management
852
Patients with esophageal strictures often experience a range of symptoms. Initially, they may have difficulty swallowing solid foods, which can progress to include liquids. Additional symptoms may involve chest pain or discomfort, regurgitating food and fluids, heartburn, unintentional weight loss, coughing or choking during meals, and hoarseness.
Healthcare providers should gather a comprehensive medical history and conduct a physical examination for diagnosis. If esophageal stricture is...

Aneurysm III: Interprofessional Care
435
Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...

Esophageal Strictures-I: Introduction
1.1K
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...

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy
974
Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...

Angle Closure Glaucoma: Treatment
1.5K
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...
