Endoscopic Procedures III: Video Capsule Endoscopy01:28

Endoscopic Procedures III: Video Capsule Endoscopy

201
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 IV: Sigmoidoscopy and Laproscopy

119
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

135
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

205
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 V: ERCP01:26

Endoscopic Procedures V: ERCP

424
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 Studies I: Bronchoscopy and Thoracoscopy01:30

Endoscopic Studies I: Bronchoscopy and Thoracoscopy

236
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...

Summary

A new EMR case selection score (EMR-CSS) helps novice endoscopists identify challenging large nonpedunculated colonic polyps (LNPCPs). This tool aids in safe and successful endoscopic mucosal resection (EMR) training by predicting difficult cases.

Area of Science:

  • Gastroenterology
  • Endoscopic Surgery
  • Medical Education

Background:

  • Endoscopic mucosal resection (EMR) for large nonpedunculated colonic polyps (LNPCPs) is expanding beyond expert centers.
  • Lack of specific tools for EMR case selection poses challenges for novice endoscopists.
  • Training is crucial to prevent failed resections and unnecessary surgical referrals.

Purpose of the Study:

  • To develop an EMR case selection score (EMR-CSS).
  • To identify potentially challenging LNPCPs for endoscopists new to EMR.
  • To improve competency and safety in early EMR training.

Main Methods:

  • Recruited consecutive LNPCP EMR cases over 130 months.
  • Recorded lesion characteristics, procedural data, and adverse events.
  • Identified predictive variables for intraprocedural bleeding (IPB), intraprocedural perforation (IPP), or unsuccessful resection to form a numerical score.

Main Results:

  • Of 1993 LNPCPs, 26.4% had a composite outcome (IPB, IPP, or unsuccessful EMR).
  • Lesion size, challenging location, and sessile morphology predicted the composite outcome.
  • A six-point EMR-CSS with a cutoff of 2 showed 81% sensitivity for challenging cases.

Conclusions:

  • The EMR-CSS is a novel tool for EMR training.
  • It identifies adenomatous LNPCPs suitable for safe and successful EMR attempts by trainees.
  • Facilitates appropriate case selection in early EMR learning curves.
