Endoscopic Procedures III: Video Capsule Endoscopy01:28

Endoscopic Procedures III: Video Capsule Endoscopy

315
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 V: ERCP01:26

Endoscopic Procedures V: ERCP

772
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.

Endoscopic Procedures I: Esophagogastroduodenoscopy01:29

Endoscopic Procedures I: Esophagogastroduodenoscopy

335
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 Laproscopy01:26

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

151
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: Colonoscopy01:25

Endoscopic Procedures II: Colonoscopy

174
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 Thoracoscopy01:30

Endoscopic Studies I: Bronchoscopy and Thoracoscopy

259
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...

Summary

Smaller endoscopes enhance interventional radiology (IR) procedures. Percutaneous endoscopy, now feasible with smaller scopes, improves guidance for nonvascular interventions in organs like the kidney and liver.

Area of Science:

  • Interventional Radiology
  • Endoscopy
  • Medical Device Technology

Background:

  • Historically, large endoscope diameters limited their use in interventional radiology (IR).
  • Significant up-sizing of access was required for endoscope placement in organs like the kidney and liver.
  • Advancements in smaller endoscopes (<11F) have made percutaneous endoscopy more feasible for IR procedures.

Purpose of the Study:

  • To review current applications and techniques of percutaneous endoscopy in interventional radiology.
  • To discuss how smaller endoscopes enhance nonvascular procedures.
  • To explore adjunctive endoscopic techniques in IR.

Main Methods:

  • Review of current literature and clinical applications of percutaneous endoscopy in IR.
  • Discussion of techniques for using smaller endoscopes via percutaneous access.
  • Exploration of endoscopy through natural or surgically created orifices.

Main Results:

  • Percutaneous endoscopy is increasingly feasible with smaller endoscopes (<11F).
  • IRs utilize percutaneous access for image- and endoscopically-guided interventions, particularly for biliary and gallbladder conditions.
  • Endoscopic guidance aids in managing urinary, gastrointestinal, and gynecologic conditions.

Conclusions:

  • Smaller endoscopes have expanded the feasibility of percutaneous endoscopy in interventional radiology.
  • Endoscopic guidance significantly improves nonvascular procedures, especially in the biliary and gallbladder systems.
  • Interventional radiologists can leverage endoscopy for various interventions, including biopsies, ablation, and stone extraction.
