Urologic Endoscopic Procedure: Cystoscopic Examination01:28

Urologic Endoscopic Procedure: Cystoscopic Examination

467
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...

Endoscopic Procedures III: Video Capsule Endoscopy01:28

Endoscopic Procedures III: Video Capsule Endoscopy

341
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

282
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...

Ultrasound II: Endoscopic Ultrasound and FibroScan

211
Endoscopic Ultrasound (EUS) and FibroScan are valuable diagnostic tools in gastroenterology and hepatology, each with specific applications and techniques.

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy01:26

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

195
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: Esophagogastroduodenoscopy01:29

Endoscopic Procedures I: Esophagogastroduodenoscopy

368
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:

  • Medical Simulation
  • Surgical Education
  • Gastroenterology

Background:

  • Surgical skill acquisition requires extensive practice, but trainee opportunities are limited by case volume.
  • Existing flexible endoscopy simulators are expensive, inaccessible, and lack portability.
  • There is a need for cost-effective, portable simulation tools for endoscopic training.

Purpose of the Study:

  • To introduce and evaluate a novel, low-cost, portable endoscopic simulation system.
  • To assess the face, content, and preliminary construct validity of the simulator.
  • To determine the simulator's utility for training basic endoscopic skills.

Main Methods:

  • Development of a portable endoscopic simulator with custom software, 3D anatomy models, and a motion-controlled endoscopic tool via Bluetooth.
  • Part 1: Face and content validity assessed by experts and novices rating fidelity and utility.
  • Part 2: Preliminary construct validity evaluated by assessing task completion time for basic endoscopic tasks in experts and novices.

Main Results:

  • The simulator demonstrated good utility as a training tool, though some features require enhancement for realism.
  • Both novice and expert users showed significant improvement in task performance with repeated practice (p < 0.001).
  • No significant differences in task completion time were observed between experts and novices.

Conclusions:

  • The portable endoscopic simulator is a promising, feasible, and cost-effective tool for basic endoscopic skills training.
  • Further validation studies are necessary to fully establish its efficacy.
  • The simulator addresses limitations of current training methods by offering accessible, portable practice opportunities.
