Endoscopic Procedures I: Esophagogastroduodenoscopy01:29

Endoscopic Procedures I: Esophagogastroduodenoscopy

2.2K
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 III: Video Capsule Endoscopy01:28

Endoscopic Procedures III: Video Capsule Endoscopy

1.3K
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 Thoracoscopy

1.0K
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: ERCP01:26

Endoscopic Procedures V: ERCP

6.6K
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.

Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding

1.9K
Enteral nutrition encompasses various methods of delivering nutrition directly to the gastrointestinal (GI) tract, bypassing traditional oral intake. It is particularly beneficial for patients who cannot eat by mouth but have a functioning digestive system. Key methods include nasointestinal feeding, gastrostomy, and jejunostomy, each suited to different clinical scenarios based on the patient's needs and condition.
Nasointestinal Feeding
Nasointestinal feeding involves placing a tube...

Upper GI Series: Barium Swallow

2.4K
The Barium Swallow Study, or a Barium Esophagogram, is a diagnostic imaging method used to visualize the upper gastrointestinal (GI) tract, including the esophagus, stomach, and small intestine. It employs barium sulfate, a radiopaque contrast material, to provide clear images of the upper digestive system, helping to identify abnormalities, diseases, or structural issues.
Purpose and Procedure
Patients undergoing this procedure ingest a liquid containing barium sulfate with a chalky...

Area of Science:

  • Ophthalmology
  • Medical Imaging
  • Pediatrics

Background:

  • Wide-field fundus imaging is crucial for diagnosing and managing pediatric retinal pathologies.
  • Current imaging technologies are often expensive or bulky, limiting accessibility, especially for pediatric evaluations.
  • Repeated evaluations in infants pose a significant challenge for diagnosis and treatment monitoring.

Purpose of the Study:

  • To develop and report a cost-effective, wide-field fundus imaging technique for infants.
  • To overcome the limitations of existing fundus imaging devices in pediatric care.
  • To enable easier and more frequent fundus examinations in infants.

Main Methods:

  • A novel technique utilizing a standard nasal endoscope coupled with viscoelastic material.
  • The endoscope-viscoelastic construct was applied to the cornea of infants under general anesthesia.
  • Wide-angle fundus images were captured using readily available instruments.

Main Results:

  • Successful acquisition of wide-angle fundus images in infants.
  • Demonstrated visualization of various fundus pathologies.
  • The technique proved to be easily implementable with minimal financial investment.

Conclusions:

  • A nasal endoscope and viscoelastic coupling offer a viable, low-cost solution for wide-field infant fundus imaging.
  • This method enhances the accessibility of advanced retinal imaging for pediatric patients.
  • Facilitates improved diagnosis, treatment, and follow-up of retinal conditions in infants.
