Endoscopic Procedures I: Esophagogastroduodenoscopy

127
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:

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

91
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...

Endoscopic Procedures II: Colonoscopy

107
The colon, or large intestine, is the final segment of the digestive system. Its primary functions include absorbing water and vitamins produced by gut bacteria and transforming waste from liquid to solid to form stool. In adults, the large intestine is approximately 5 feet long and consists of four main sections:

Esophageal Varices-II: Clinical Features and Management01:28

Esophageal Varices-II: Clinical Features and Management

72
Esophageal varices often manifest as gastrointestinal bleeding episodes, presenting symptoms like hematemesis (vomiting of blood), hematochezia (passing fresh blood via the rectum), and melena (black, tarry stools). Other signs can include weight loss, anorexia, abdominal discomfort, jaundice, pruritus, altered mental status, and muscle cramps.
In the initial assessment, a thorough review of the patient's medical history is vital to identify risk factors such as liver disease, alcohol...

Endoscopic Procedures V: ERCP01:26

Endoscopic Procedures V: ERCP

272
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.

科学领域:

  • 胃肠病学 胃肠病学
  • 内視鏡外科手術 內視鏡外科手術
  • 在瘤学瘤学.

背景情况:

  • 胃内镜下粘膜切割 (ESD) 是胃瘤的关键治疗方法.
  • 延迟出血是已知的胃ESD的并发症.
  • 二次内镜在预防ESD后早期延迟出血的疗效仍未得到充分研究.

研究的目的:

  • 调查即时二次观察内镜在预防早期延迟ESD后出血方面的疗效.
  • 为了确定与早期延迟ESD后出血相关的风险因素.

主要方法:

  • 一项回顾性研究分析了262例胃ESD病例.
  • 患者被分为三组:立即第二次观察,预定第二次观察和没有第二次观察内镜.
  • 立即的第二次观察内镜被定义为在初始血液静止后不久的重复内镜.

主要成果:

  • 整体ESD后出血率为7.3%,其中68.4%被归类为早期延迟出血.
  • 立即的二次内镜显著降低了ESD后早期延迟出血的发生率 (3.8%对0.8%,p=0.009).
  • 切割样本面积≥1,000mm2是早期延迟出血的一个独立风险因素 (OR 8.98,p=0.010).

结论:

  • 立即的第二次观察内镜显示出在胃ESD后预防早期延迟出血的潜力.
  • 这种策略可能特别有利于大面积切割的情况.
  • 进一步的研究可能会对特定的患者子组完善这种技术的应用.
