Endoscopic Procedures V: ERCP01:26

Endoscopic Procedures V: ERCP

227
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: Esophagogastroduodenoscopy

115
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 Studies I: Bronchoscopy and Thoracoscopy01:30

Endoscopic Studies I: Bronchoscopy and Thoracoscopy

194
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...

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

84
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

94
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
  • Interventional Endoscopy
  • Medical Imaging

Background:

  • Therapeutic endoscopic ultrasonography (EUS) has evolved significantly.
  • Forward-viewing convex EUS (FV-EUS) represents a key advancement in this field.
  • Reviewing existing literature highlights the procedural capabilities of FV-EUS.

Purpose of the Study:

  • To review therapeutic endoscopic ultrasonography (EUS) procedures utilizing forward-viewing convex EUS (FV-EUS).
  • To summarize the reported applications and benefits of FV-EUS in interventional procedures.
  • To identify scenarios where FV-EUS offers distinct advantages over conventional methods.

Main Methods:

  • Literature review of reported therapeutic EUS procedures using FV-EUS.
  • Analysis of studies detailing FV-EUS characteristics and applications.
  • Categorization of procedures based on anatomical context and technical requirements.

Main Results:

  • The earliest application of FV-EUS was for pancreatic pseudocyst drainage.
  • FV-EUS facilitates EUS-guided choledochoduodenostomy, potentially avoiding double punctures.
  • Reported uses include drainage of bile ducts, pancreatic ducts, and abscesses in modified anatomical settings.
  • FV-EUS is advantageous for perpendicular punctures and deep endoscope insertion.

Conclusions:

  • Forward-viewing convex EUS (FV-EUS) is a versatile tool for various therapeutic interventions.
  • FV-EUS offers procedural benefits, including avoiding multiple punctures and enabling complex drainage.
  • Its utility is particularly noted in modified anatomical cases and when specific puncture angles or depths are required.
