Endoscopic Procedures III: Video Capsule Endoscopy01:28

Endoscopic Procedures III: Video Capsule Endoscopy

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, unexplained...
Endoscopic Procedures II: Colonoscopy01:25

Endoscopic Procedures II: Colonoscopy

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 I: Esophagogastroduodenoscopy01:29

Endoscopic Procedures I: Esophagogastroduodenoscopy

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 Studies I: Bronchoscopy and Thoracoscopy01:30

Endoscopic Studies I: Bronchoscopy and Thoracoscopy

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 to...
Endoscopic Procedures V: ERCP01:26

Endoscopic Procedures V: ERCP

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 IV: Sigmoidoscopy and Laproscopy01:26

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

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...

Area of Science:

  • Gastroenterology and Endoscopic Imaging
  • Biophotonics and Optical Diagnostics

Context:

  • Early detection of gastrointestinal neoplastic lesions is crucial for effective treatment.
  • Traditional endoscopy relies on visual assessment of mucosal features.
  • Advancements in endoscopic imaging aim to improve diagnostic accuracy.

Purpose:

  • To evaluate the utility of electronic virtual chromoendoscopy in visualizing gastrointestinal microvessel morphology.
  • To assess the role of Narrow Band Imaging (NBI) and Multi-Band Imaging (FICE) in detecting and differentiating neoplastic lesions.
  • To explore the scientific basis of virtual chromoendoscopy utilizing short wavelength light and hemoglobin absorption.

Summary:

  • Electronic virtual chromoendoscopy, including NBI and FICE, enhances capillary pattern contrast by leveraging short wavelength light absorption by hemoglobin.
  • This technique allows for in vivo visualization of microvessel morphological changes in superficial neoplastic lesions.
  • It aids in the detection of premalignant lesions and differentiation between neoplastic and non-neoplastic tissues.

Impact:

  • Virtual chromoendoscopy offers a readily available tool for improved endoscopic assessment.
  • Its ease of use and routine availability are expected to increase its adoption in clinical practice.
  • Further well-designed prospective studies are needed to definitively establish its role in daily endoscopy.
