Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy01:26

Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy

198
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 II: Colonoscopy01:25

Endoscopic Procedures II: Colonoscopy

292
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

246
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

404
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

317
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...

Area of Science:

  • Gastroenterology
  • Medical Imaging
  • Artificial Intelligence in Medicine

Background:

  • Artificial intelligence (AI) has demonstrated potential in enhancing colonoscopy quality by increasing the adenoma detection rate (ADR).
  • The influence of endoscopist experience on AI's impact on ADR remains unclear.
  • This study compares AI performance in novice versus expert endoscopists.

Purpose of the Study:

  • To evaluate the effectiveness of a real-time deep-learning computer-aided detection (CADe) system in improving ADR among non-expert endoscopists.
  • To compare the performance of CADe in novice endoscopists with previously published data from expert endoscopists.
  • To determine the role of physician experience in AI-assisted adenoma detection.

Main Methods:

  • A prospective, randomized controlled non-inferiority trial (AID-2) involving 10 non-expert endoscopists (<2000 colonoscopies).
  • Participants underwent screening/surveillance/diagnostic colonoscopies with or without CADe (GI Genius, Medtronic).
  • Data were compared post-hoc with a prior trial (AID-1) of 6 expert endoscopists.

Main Results:

  • Overall ADR was significantly higher in the CADe group compared to the control group (53.3% vs 44.5%; RR: 1.22; p<0.01).
  • CADe use increased adenoma detection, particularly for small and distal lesions.
  • When pooled with AID-1 data, CADe use was associated with higher ADR, while endoscopist experience showed no significant impact (RR 1.02; 95% CI: 0.89 to 1.16).

Conclusions:

  • Computer-aided detection (CADe) significantly increases adenoma detection rates (ADR) in colonoscopies performed by less experienced endoscopists.
  • The level of endoscopist experience appears to have a minimal impact on ADR when using CADe.
  • AI-assisted colonoscopy offers a promising tool to improve diagnostic yield across varying levels of physician expertise.
