Endoscopic Procedures I: Esophagogastroduodenoscopy

74
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
  • Surgical Oncology
  • Laser Surgery

Background:

  • Laryngeal squamous cell carcinoma presents treatment challenges.
  • Traditional microsurgery may impact laryngeal and swallowing functions.
  • Minimally invasive techniques are sought for improved outcomes.

Purpose of the Study:

  • To present a case of laryngeal cancer treated with CO2 transoral laser exoscopic surgery (TOLES).
  • To evaluate the efficacy and functional preservation of TOLES.
  • To highlight TOLES as an alternative to traditional laryngeal surgery.

Main Methods:

  • A case report of an 85-year-old patient with cT2N0 laryngeal squamous cell carcinoma.
  • Treatment performed using CO2 transoral laser exoscopic surgery (TOLES).
  • En bloc tumor removal with assessment of surgical margins and functional outcomes.

Main Results:

  • Successful en bloc removal of the laryngeal tumor.
  • Achieved negative surgical margins.
  • Preserved laryngeal and swallowing functions post-surgery.

Conclusions:

  • CO2 transoral laser exoscopic surgery (TOLES) is a viable treatment for laryngeal squamous cell carcinoma.
  • TOLES offers enhanced visualization and ergonomics compared to traditional microsurgery.
  • The technique effectively removes tumors while preserving critical laryngeal functions.
