Endoscopic Procedures I: Esophagogastroduodenoscopy

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:

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...

Endoscopic Procedures III: Video Capsule Endoscopy

Endoscopic Procedures III: Video Capsule Endoscopy

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,...

Endoscopic Procedures II: Colonoscopy

Endoscopic Procedures II: Colonoscopy

The colon, or large intestine, is the final segment of the digestive system. Its primary functions include absorbing water and vitamins produced by gut bacteria and transforming waste from liquid to solid to form stool. In adults, the large intestine is approximately 5 feet long and consists of four main sections:

Area of Science:

Gastroenterology
Surgical Education

Background:

Gastroscopy is crucial for stomach disease management.
Systematic gastroscopy training for surgeons is lacking in Korea.

Purpose of the Study:

Introduce the first systematic gastroscopy education program for surgeons in Korea.
Assess the program's practicality and clinical relevance.

Main Methods:

Developed the
Gastroscopy School for Surgeons (GSS)
program: theory, dry lab, and clinical practice.
33 surgeons with no prior experience participated.
Analyzed educational performance and participant surveys.

Main Results:

Participants performed 2,272 gastroscopies, including 2,008 post-gastrectomy cases.
Most participants (75.8%) rated their skills as proficient.
All participants found systematic surgical gastroscopy education necessary.

Conclusions:

The GSS program is a practical and needed initiative for Korean surgeons.
Expansion of training centers is recommended to increase access.
The program effectively addresses clinical needs in gastroscopy.
