Endoscopic Procedures III: Video Capsule Endoscopy01:28

Endoscopic Procedures III: Video Capsule Endoscopy

1.2K
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 Procedures II: Colonoscopy

1.1K
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:

Urologic Endoscopic Procedure: Cystoscopic Examination

5.3K
Meaning of Cystoscopic Examination:Cystoscopy is an essential diagnostic tool in urology that is used to assess the structure and function of the genitourinary system. It provides a direct view of the urethra, bladder, and, in some cases, the ureteral openings. This procedure helps detect structural abnormalities, infections, cancers, and blockages in the urinary tract. There are two types of cystoscopy:Flexible cystoscopy is commonly performed in outpatient settings due to its less invasive...

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

792
Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

1.0K
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 I: Esophagogastroduodenoscopy

1.9K
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:

Area of Science:

  • Gastroenterology
  • Medical Imaging
  • Computational Analysis

Background:

  • Video capsule endoscopy diagnostic yield is often limited by poor bowel preparation.
  • Objective assessment of bowel preparation quality is crucial but lacks validation.
  • Current methods for evaluating small bowel preparation are subjective and inconsistent.

Purpose of the Study:

  • To design and validate a computed small bowel preparation score.
  • To provide an objective, user-friendly tool for research and clinical use.
  • To improve the standardization of video capsule endoscopy procedures.

Main Methods:

  • Two experienced physicians established a consensus on bowel preparation quality criteria.
  • A computational algorithm was developed based on pixel analysis of the color bar.
  • Concordance between physician assessment (gold standard) and the computed score was evaluated.

Main Results:

  • Physician agreement classified 52% of cases as adequate, 15% borderline, and 33% inadequate.
  • The computer analysis achieved 90% agreement for adequate/inadequate cases (Kappa 0.79).
  • Overall agreement including borderline cases was 84% (Kappa 0.72), with minute-by-minute analysis showing 91.4% agreement.

Conclusions:

  • A user-friendly, computer-based small bowel preparation score was developed.
  • The score demonstrated excellent concordance with physician assessments.
  • This tool has potential for standardizing bowel preparation assessment in video capsule endoscopy research and practice.
