Endoscopic Procedures I: Esophagogastroduodenoscopy

1.7K
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 Endoscopy

1.1K
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:

  • Gastroenterology
  • Endoscopic Surgery

Background:

  • Endoscopic submucosal dissection (ESD) is a minimally invasive technique for managing early gastrointestinal malignancies.
  • Its application is expanding beyond cancer treatment to conditions like achalasia, submucosal tumors, and reflux disease.

Purpose of the Study:

  • To provide an overview of the current and emerging equipment used in ESD procedures.
  • To discuss essential techniques that enhance ESD efficiency and safety.

Main Methods:

  • Review of current and novel endoscopic devices, including endoscopes, generators, and specialized tools.
  • Description of key ESD techniques such as countertraction and artificial ulcer closure.

Main Results:

  • ESD requires specialized skills, training, and a comprehensive understanding of various devices and techniques.
  • Familiarity with equipment and techniques improves procedure speed, efficiency, and safety.

Conclusions:

  • ESD is a versatile endoscopic procedure for various gastrointestinal conditions.
  • Technological advancements and refined techniques are crucial for optimizing ESD outcomes.
