Endoscopic Procedures I: Esophagogastroduodenoscopy01:29

Endoscopic Procedures I: Esophagogastroduodenoscopy

403
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: ERCP

1.1K
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.

Anatomy of the Ear

Auditory sensation, commonly called hearing, involves the transformation of sonic waves into neural impulses facilitated by the structures of the auditory organ. The prominent, flesh-like structure on the side of the head, called the auricle, directs sound waves towards the auditory canal. The auricle is often mislabeled as the pinna, a term more aligned with mobile structures like a feline's external ear. The auditory canal penetrates the cranium via the external auditory meatus of the...

Endoscopic Procedures III: Video Capsule Endoscopy

363
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,...

Area of Science:

  • Otolaryngology
  • Surgical Education
  • Medical Imaging

Background:

  • Traditional otologic surgical training relied on microscopic cadaveric dissections.
  • Endoscopic techniques have revolutionized the surgical perspective in otology.
  • Modern ear and lateral skull base surgeons need expertise in both microscopic and endoscopic approaches.

Purpose of the Study:

  • To propose a guided, illustrated dissection course for otologic surgery.
  • To demonstrate the integration of microscopes and endoscopes in cadaveric training.
  • To enhance surgeon proficiency in both endoscopic and microscopic otologic procedures.

Main Methods:

  • Development of a step-by-step guided and illustrated dissection course.
  • Detailed instructions for cadaver laboratory setup.
  • Integration of both microscope and endoscope for training.

Main Results:

  • The course facilitates training in handling both endoscopic and microscopic instruments.
  • Alternating between endoscope and microscope allows novices to master both views.
  • This integrated approach is crucial for developing comprehensive otologic surgical skills.

Conclusions:

  • Mastery of both endoscopic and microscopic techniques is essential for modern otologic and lateral skull base surgery.
  • This training course effectively integrates both optical views for comprehensive skill development.
  • Tailoring procedures using both approaches ensures the best functional outcomes for patients.
