Endoscopic Procedures II: Colonoscopy01:25

Endoscopic Procedures II: Colonoscopy

199
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

378
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

200
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 Studies I: Bronchoscopy and Thoracoscopy01:30

Endoscopic Studies I: Bronchoscopy and Thoracoscopy

283
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...

Endoscopic Procedures V: ERCP

1.0K
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 III: Video Capsule Endoscopy01:28

Endoscopic Procedures III: Video Capsule Endoscopy

345
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,...

Summary

Endoscopy training quality in the UK shows significant variation, with most units falling short of Joint Advisory Group on Gastrointestinal Endoscopy Training (JETS) standards. Key performance indicators reveal underperformance in training frequency and skills assessment.

Area of Science:

  • Medical Education
  • Gastroenterology
  • Surgical Training

Background:

  • Endoscopy training is crucial for patient care quality.
  • The UK has established standards for gastrointestinal endoscopy training (JETS).
  • Assessing current training quality against these standards is essential.

Purpose of the Study:

  • To evaluate the quality of endoscopy training programs within a UK Statutory Educational Body.
  • To compare the observed training quality against the established Joint Advisory Group on Gastrointestinal Endoscopy Training (JETS) standards.

Main Methods:

  • Analysis of 28,298 procedures from 211 trainees across 18 UK hospitals in 2019.
  • Inclusion of data on trainer/trainee numbers, procedure frequency, and Direct Observation of Procedural Skills (DOPS) completion.
  • Evaluation of Key Performance Indicators (KPIs) for esophagogastroduodenoscopy and colonoscopy.

Main Results:

  • Training list frequency per trainee was 35% below the JETS standard.
  • Direct Observation of Procedural Skills (DOPS) completion was significantly lower than JETS recommendations (0.2 per list vs. 20 per 200 procedures).
  • Significant variation in training quality was observed, with a three-fold difference in compound hospital scores; most units underperformed.

Conclusions:

  • A notable disparity exists in the quality of endoscopy training across UK hospitals.
  • Most training units do not meet the JETS standards for training frequency and skills assessment.
  • Awareness of performance metrics and formal adjuncts are recommended to enhance endoscopy training quality.
