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:

Pharyngeal squamous cell carcinoma (SCC) detection is increasing, with endoscopic submucosal dissection (ESD) offering a minimally invasive treatment. This review examines pharyngeal ESD, highlighting challenges and proposing education to increase its adoption in Western practice.

Area of Science:

  • Gastroenterology
  • Oncology
  • Surgical Endoscopy

Background:

  • Pharyngeal squamous cell carcinoma (SCC) is increasingly diagnosed at earlier stages, particularly in Japan.
  • Endoscopic submucosal dissection (ESD) is a preferred minimally invasive treatment for superficial pharyngeal SCC with excellent outcomes.
  • Pharyngeal ESD remains underutilized in Western countries despite rising pharyngeal cancer incidence.

Purpose of the Study:

  • To review current evidence on pharyngeal endoscopic submucosal dissection (ESD).
  • To discuss indications, techniques, outcomes, and adverse events associated with pharyngeal ESD.
  • To identify barriers to pharyngeal ESD adoption in Western practice and propose solutions.

Main Methods:

  • Systematic review of contemporary series on pharyngeal ESD.

The Pocket-Creation Procedure of Endoscopic Submucosal Dissection for Large Rectal Laterally Spreading Tumors

Published on: February 13, 2026

  • Analysis of en bloc and R0 resection rates.
  • Evaluation of serious adverse events and unique technical challenges.

    • Main Results:

    • Pharyngeal ESD consistently achieves high en bloc and R0 resection rates.
    • Serious adverse events associated with pharyngeal ESD are infrequent.
    • Complex anatomy, specialized anesthesia, and exposure techniques present unique challenges.

    Conclusions:

    • Pharyngeal ESD is a safe and effective treatment for early pharyngeal SCC.
    • Barriers to Western adoption include limited knowledge in optical diagnosis.
    • Targeted education is proposed to bridge the knowledge gap and increase pharyngeal ESD utilization.
