Endoscopic Procedures I: Esophagogastroduodenoscopy01:29

Endoscopic Procedures I: Esophagogastroduodenoscopy

815
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 V: ERCP01:26

Endoscopic Procedures V: ERCP

2.5K
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 Procedures II: Colonoscopy01:25

Endoscopic Procedures II: Colonoscopy

562
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:

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy01:26

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

514
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 III: Video Capsule Endoscopy01:28

Endoscopic Procedures III: Video Capsule Endoscopy

668
Capsule endoscopy, or wireless or video capsule endoscopy, is a diagnostic procedure for examining the entire gastrointestinal tract. Patients swallow a capsule about the size of a vitamin tablet. The capsule is equipped with a transmitter, a battery, an LED light source, and a color video camera to capture images throughout the gastrointestinal tract. This procedure is particularly useful for diagnosing conditions such as Crohn's disease, ulcerative colitis, tumors, polyps, ulcers,...

Endoscopic Studies I: Bronchoscopy and Thoracoscopy01:30

Endoscopic Studies I: Bronchoscopy and Thoracoscopy

492
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
This summary is machine-generated.

Many individuals are unaware of potential complications from screening colonoscopy and upper gastrointestinal endoscopy (UGIE). Increasing awareness of these risks can improve adherence to vital cancer screening procedures.

Area of Science:

  • Gastroenterology
  • Oncology
  • Public Health

Background:

  • Endoscopic procedures are crucial for colorectal cancer (CRC) and gastric cancer screening.
  • Patient adherence to screening may be influenced by perceived risks of complications.
  • Understanding risk perception is key to improving screening participation.

Purpose of the Study:

  • To assess individuals' perceived risk of complications from screening colonoscopy and upper gastrointestinal endoscopy (UGIE).
  • To explore the relationship between risk perception, awareness of complications, and willingness to undergo endoscopic screening.

Main Methods:

  • A cross-sectional study was conducted in northern Portugal.
  • Participants eligible for CRC screening were interviewed via telephone using the PERCEPT-PREVENT tool.
  • Two groups were analyzed: never-screened individuals and those previously screened endoscopically.

Main Results:

  • A significant majority (61% for colonoscopy, 83% for UGIE) were unaware of potential complications.
  • Never-screened individuals reported lower perceived complication risks compared to those previously screened.
  • Lower perceived risk for UGIE complications correlated with higher willingness for combined screening (colonoscopy and UGIE).
  • Participants undergoing combined screening demonstrated higher complication awareness and lower risk perception.

Conclusions:

  • Enhancing patient awareness of endoscopic screening complications is essential.
  • Improved risk perception and knowledge can significantly increase adherence to CRC and gastric cancer screening programs.
