Endoscopic Procedures I: Esophagogastroduodenoscopy01:29

Endoscopic Procedures I: Esophagogastroduodenoscopy

358
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 Laproscopy

180
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

335
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

276
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...

Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques

91
Airway management is essential in emergency and surgical medicine, ensuring ventilation and oxygenation in patients who cannot maintain their own airway. Clinicians use a range of techniques and devices to secure the airway, depending on the patient’s condition and the clinical context. Key methods include endotracheal intubation, rapid sequence intubation (RSI), supraglottic airway devices, and advanced visualization aids. In cases where these approaches fail, surgical airway...

Endoscopic Studies II: Thoracocentesis01:26

Endoscopic Studies II: Thoracocentesis

526
Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...

Area of Science:

  • Otolaryngology
  • Medical Device Technology
  • Diagnostic Imaging

Background:

  • Laryngeal diseases frequently affect the posterior glottis and subglottis.
  • Conventional laryngoscopes offer limited visualization of these areas due to disease obstruction.
  • Accurate diagnosis and treatment are hindered by poor visibility of subglottic pathology.

Purpose of the Study:

  • To introduce a novel device for imaging the subglottic space.
  • To overcome visualization limitations of current endoscopic techniques.
  • To enable minimally invasive assessment of subglottic laryngeal conditions.

Main Methods:

  • Development of the subglottic imaging puncture scope (SIPS).
  • Integration of a miniature, high-resolution camera into a gauge 18 needle.
  • Testing the device via transcervical puncture in human cadavers.

Main Results:

  • Successful imaging of the subglottic space was achieved using the SIPS.
  • The device demonstrated minimal invasiveness, comparable to drug delivery techniques.
  • Video footage validated the feasibility of visualizing the subglottis through puncture.

Conclusions:

  • The SIPS offers a new approach for visualizing the subglottis.
  • This technology can improve diagnostic accuracy for subglottic diseases.
  • The device promises enhanced patient comfort and enables in-office imaging of subglottic pathology.
