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 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 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...
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:
Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy01:30

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy

Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the colonic...
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.

Summary

Coeliac disease (CD) is a gluten-triggered inflammatory condition. Advancements in endoscopic imaging, from the Crosby capsule to wireless video capsule endoscopy (VCE) and double balloon enteroscopy (DBE), have significantly improved CD diagnosis and complication detection.

Area of Science:

  • Gastroenterology
  • Immunology
  • Medical Imaging

Background:

  • Coeliac disease (CD) is a chronic inflammatory enteropathy triggered by gluten in genetically susceptible individuals (HLA DQ2/DQ8 positive).
  • CD affects 1-2% of specific populations and shares characteristics with autoimmune diseases.
  • The identification of gluten as the specific trigger and advancements in endoscopic techniques are unique aspects of CD research.

Purpose of the Study:

  • To highlight the evolution of endoscopic imaging in diagnosing coeliac disease.
  • To emphasize how technological advancements have improved the detection of CD and its complications.

Main Methods:

  • Review of historical and modern endoscopic techniques for small bowel examination.
  • Mention of the Crosby capsule for non-surgical small bowel biopsy.
  • Inclusion of wireless video capsule endoscopy (VCE) and double balloon enteroscopy (DBE) for enhanced imaging and sampling.

Main Results:

  • Flexible endoscopy has enabled easier and safer small bowel tissue collection.
  • Modern endoscopic tools like VCE and DBE have expedited the diagnosis of coeliac disease.
  • These advancements facilitate the identification of serious CD complications, including small bowel adenocarcinoma, refractory coeliac disease type II (RCDII), and enteropathy-associated T-cell lymphoma (EATL).

Conclusions:

  • Endoscopic imaging has revolutionized the diagnosis and management of coeliac disease over the past 50 years.
  • Technological progress in endoscopy allows for earlier and more accurate detection of CD and its severe sequelae.
