Endoscopic Procedures V: ERCP01:26

Endoscopic Procedures V: ERCP

965
Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.

Inflammatory Bowel Disease V: Surgical Management

224
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

163
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...

Esophageal Strictures-I: Introduction

278
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...

概括

诊断胆道狭窄是很困难的. 先进的内镜技术,如内镜超声波和口腔胆血管镜 (POCS) 为不明确的病例提供了更好的诊断产量,但最佳使用需要进一步研究.

  • 胃肠病学 胃肠病学
  • 干预性内镜检查是干预性的内镜检查.
  • 诊断成像 诊断成像 诊断成像

背景情况:

  • 胆管狭窄的诊断是具有挑战性的,因为传统的内镜逆行胆血管瘤学 (ERCP) 采样的敏感性较低.
  • 不确定的胆道狭窄通常需要额外的内镜手术来确定确诊.

研究的目的:

  • 评估诊断产量和先进内镜技术的最佳应用,用于不确定的胆道狭窄.
  • 为了比较基于狭窄位置的内镜超声波导向采样和口腔胆血管镜 (POCS) 导向活检.

主要方法:

  • 对无限期胆道狭窄的诊断方式的审查,包括内镜超声波导向采样和POCS导向活检.
  • 基于狭窄位置 (距离与周围) 的模式选择分析.

主要成果:

  • 内镜超声波是偏远胆道狭窄的首选,而POCS是偏远周围胆道狭窄的首选.
  • 以内镜超声波导向的采样显示了对质量的高灵敏度;以POCS导向的活检灵敏度不令人满意,容易出现视觉差异.
  • 对于先进技术的最佳时间 (初始与救援程序) 仍然不清楚.

结论:

  • 先进的内镜技术提高了胆道狭窄的诊断产量,具有特定位置的偏好.
