Endoscopic Procedures I: Esophagogastroduodenoscopy01:29

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.

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 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: 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.

Summary
This summary is machine-generated.

Immediate second-look endoscopy after gastric endoscopic submucosal dissection (ESD) can prevent early delayed bleeding. This study found it significantly reduced bleeding risk, especially for large resections, offering a new strategy for gastric neoplasm treatment.

Area of Science:

  • Gastroenterology
  • Endoscopic Surgery
  • Oncology

Background:

  • Gastric endoscopic submucosal dissection (ESD) is a key treatment for gastric neoplasm.
  • Delayed bleeding is a known complication of gastric ESD.
  • The efficacy of second-look endoscopy in preventing early delayed bleeding post-ESD remains under-investigated.

Purpose of the Study:

  • To investigate the efficacy of immediate second-look endoscopy in preventing early delayed post-ESD bleeding.
  • To identify risk factors associated with early delayed post-ESD bleeding.

Main Methods:

  • A retrospective study analyzing 262 gastric ESD cases.
  • Patients were divided into three groups: immediate second-look, scheduled second-look, and no second-look endoscopy.
  • Immediate second-look endoscopy was defined as repeat endoscopy shortly after initial hemostasis.

Main Results:

  • The overall post-ESD bleeding rate was 7.3%, with 68.4% classified as early delayed bleeding.
  • Immediate second-look endoscopy significantly reduced the incidence of early delayed post-ESD bleeding (3.8% vs. 0.8%, p=0.009).
  • Resected specimen area ≥ 1,000 mm² was an independent risk factor for early delayed bleeding (OR 8.98, p=0.010).

Conclusions:

  • Immediate second-look endoscopy shows potential in preventing early delayed bleeding after gastric ESD.
  • This strategy may be particularly beneficial in cases with large resected areas.
  • Further research may refine the application of this technique for specific patient subgroups.
