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 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:

Endoscopic Studies I: Bronchoscopy and Thoracoscopy

Endoscopic Studies I: Bronchoscopy and Thoracoscopy

Endoscopy is a non-surgical medical technique used to examine a person's internal organs and vessels. This lesson will focus on two types of endoscopic studies: bronchoscopy and thoracoscopy.
Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due to...

Endoscopic Procedures V: ERCP

Endoscopic Procedures V: ERCP

Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.
Patient...

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, unexplained...

Area of Science:

Gastroenterology
Medical Technology

Background:

Gastrointestinal endoscopy has evolved from basic visual inspection to complex diagnostic and therapeutic interventions.
Many advanced endoscopic techniques are not yet widely adopted due to complexity or cost.

Purpose of the Study:

To review emerging endoscopic technologies for enhancing diagnostic yield in the colon and small intestine.
To discuss the potential of specific tools in managing digestive diseases.

Main Methods:

Review of recent advancements in gastrointestinal endoscopy.
Discussion of specific technologies including Third Eye® Retroscopes®, colon capsule endoscopy, spiral enteroscopy, and confocal laser endomicroscopy.
Evaluation of over-the-scope clip devices for perforation closure and tumor removal.

Main Results:

Emerging endoscopic techniques offer significant progress in managing digestive diseases.
Specific technologies discussed show promise in improving diagnostic accuracy and therapeutic options.
Over-the-scope clip devices present a simple, cost-effective tool for non-invasive interventions.

Conclusions:

Advanced endoscopic tools are transforming the management of gastrointestinal disorders.
Innovations in endoscopy are increasing diagnostic precision and therapeutic efficacy.
New technologies, like capsule endoscopy and clip devices, are expanding the capabilities of endoscopic procedures.
