Endoscopic Procedures I: Esophagogastroduodenoscopy01:29

Endoscopic Procedures I: Esophagogastroduodenoscopy

315
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:

Transmission-based Precautions II: Airborne and Protective Environment01:25

Transmission-based Precautions II: Airborne and Protective Environment

1.3K
Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...

Standard Precaution

2.1K
Standard precautions are the minimum infection control safeguards used while caring for all patients, irrespective of their disease condition. They help prevent the spread of common infectious microorganisms to healthcare workers, patients, and visitors in all healthcare settings.
Hand hygiene is the most crucial means to prevent the transmission of disease. Employers are legally required to provide their workers with personal protective equipment (PPE) to minimize exposure or contact with...

PPE Use in Healthcare Settings II: Doffing01:10

PPE Use in Healthcare Settings II: Doffing

1.0K
The sequence of removing or doffing PPE starts with the gloves, as they are the most contaminated. Next is removal of the face shield or goggles, as they would interfere with removing other PPE. Then remove the gown, followed by the mask or respirator. Perform hand hygiene between steps if hands become contaminated and immediately after removing all PPE. Generally, the outside front and sleeves of the isolation gown, the goggles or the mask, the respirator, and the face shield are contaminated.

Endoscopic Procedures V: ERCP01:26

Endoscopic Procedures V: ERCP

675
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.

Endoscopic Studies I: Bronchoscopy and Thoracoscopy01:30

Endoscopic Studies I: Bronchoscopy and Thoracoscopy

249
Endoscopy is a non-surgical medical technique used to examine a person's internal organs and vessels. This lesson will focus on two types of endoscopic studies: bronchoscopy and thoracoscopy.
Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...

Summary

Gastrointestinal endoscopy poses a bacterial exposure risk to endoscopists, particularly during therapeutic colonoscopies. Awareness of microbial transmission from scattering fluids is crucial for preventing infections.

Area of Science:

  • Microbiology
  • Gastroenterology
  • Infection Control

Background:

  • Gastrointestinal endoscopy procedures carry an inherent risk of bacterial exposure for healthcare professionals.
  • Historically, attention to microorganism transmission during endoscopy was limited, increasing potential risks for endoscopists.

Purpose of the Study:

  • To investigate the incidence of bacterial exposure on endoscopists' faces during gastrointestinal endoscopic procedures.
  • To quantify the risk of bacterial contamination associated with different types of endoscopic interventions.

Main Methods:

  • A retrospective study involving endoscopists at Hirosaki University Hospital from August to October 2020.
  • Endoscopists wore masks with attached sterile films to collect potential microbial contaminants.
  • Bacterial identification utilized culture methods, Gram staining, and 16S rRNA gene sequencing.

Main Results:

  • Bacterial culture positivity was observed in 12.6% of samples.
  • Therapeutic endoscopy showed a significantly higher incidence of bacterial exposure compared to diagnostic procedures.
  • Staphylococci species were the most frequently identified bacteria, with increased positivity noted in therapeutic colonoscopies.

Conclusions:

  • Therapeutic colonoscopy procedures significantly increase the risk of bacterial exposure to endoscopists' faces.
  • Endoscopists must recognize the risk of microbial infection from fluid ejected from the endoscope's working channel.
  • Enhanced protective measures may be warranted during high-risk endoscopic interventions.
