Endoscopic Procedures I: Esophagogastroduodenoscopy

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:

  • Otolaryngology
  • Neurosurgery
  • Medical Imaging

Background:

  • Endoscopic sinus surgeries (ESS) are standard for refractory sinus disorders.
  • Two-dimensional visualization in ESS poses risks near critical structures.
  • Conversions to open surgery were sometimes necessary due to limited visualization.

Purpose of the Study:

  • To evaluate the utility of neuronavigation systems in enhancing endoscopic sinus surgeries.
  • To assess the impact of neuronavigation on managing complex nasal and sinus pathologies.

Main Methods:

  • Utilized the Neurosurgical department's neuronavigation system during ESS procedures.
  • Applied neuronavigation across a series of patients with various nasal and sinus pathologies.

Main Results:

  • Neuronavigation systems facilitate improved visualization during ESS.
  • Implementation aided surgeons in managing difficult anatomical approaches.
  • The system assisted in eradicating nasal and sinus pathologies more effectively.

Conclusions:

  • Neuronavigation integration enhances the safety and efficacy of ESS.
  • This technology is valuable for complex sinus surgeries with critical structure proximity.
  • Neuronavigation represents a significant advancement in endoscopic sinus surgery.
