Endoscopic Procedures I: Esophagogastroduodenoscopy01:29

Endoscopic Procedures I: Esophagogastroduodenoscopy

69
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:

Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy

51
This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and...

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

51
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 V: ERCP01:26

Endoscopic Procedures V: ERCP

90
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.

Lower GI Series: Barium Enema01:23

Lower GI Series: Barium Enema

189
A Barium Enema, or a lower GI series, is a specialized radiographic examination designed to visualize the lower gastrointestinal tract, specifically the colon and rectum. This procedure is instrumental in diagnosing various conditions such as colorectal cancer, polyps, diverticulosis, and inflammatory bowel disease.
Procedure Details
The examination begins by inserting a lubricated rectal tube into the patient's rectum to administer a radiopaque barium solution. The barium flow is carefully...

Endoscopic Procedures II: Colonoscopy01:25

Endoscopic Procedures II: Colonoscopy

57
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:

Area of Science:

  • Medical Imaging
  • Gastroenterology
  • Radiation Safety

Background:

  • Fluoroscopy is crucial for advanced gastrointestinal endoscopy.
  • Radiation exposure from fluoroscopy poses risks to patients and staff.
  • There is a need for standardized safety protocols.

Purpose of the Study:

  • To establish consensus-based statements for safe and effective fluoroscopy use in GI endoscopy.
  • To prioritize the well-being of healthcare workers and patients.
  • To mitigate radiation exposure risks.

Main Methods:

  • A modified Delphi approach was used over three survey rounds.
  • Consensus was defined as ≥80% agreement among 46 international experts (endoscopists and nurses).
  • Statements were prioritized using a 1-10 scale.

Main Results:

  • 31 consensus statements were achieved from 43 initial items.
  • Statements covered general considerations, education, pregnancy, family planning, patient safety, and staff safety.
  • 87.2% of statements were rated as very high priority (mean score ≥ 9).

Conclusions:

  • Consensus-based statements provide a framework for safe fluoroscopy use in GI endoscopy.
  • These guidelines aim to balance the benefits of fluoroscopy with radiation risk mitigation.
  • The study promotes a culture of safety in healthcare settings regarding fluoroscopy use.
