Endoscopic Procedures V: ERCP01:26

Endoscopic Procedures V: ERCP

1.1K
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 III: Video Capsule Endoscopy

356
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 I: Esophagogastroduodenoscopy

396
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

207
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 Studies I: Bronchoscopy and Thoracoscopy

291
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 II: Colonoscopy

234
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
  • Endoscopy
  • Biliary Tract Imaging

Background:

  • SpyGlass cholangioscopy is a novel endoscopic technique for direct biliary tract visualization.
  • It is indicated for diagnosing indeterminate biliary strictures and treating difficult bile duct stones.

Purpose of the Study:

  • To evaluate the utility and efficacy of the SpyGlass system in clinical practice.

Main Methods:

  • The study involved 14 diagnostic and 15 therapeutic SpyGlass procedures between 2018 and 2021.
  • Diagnostic procedures focused on indeterminate biliary strictures, while therapeutic procedures targeted difficult bile duct stones.

Main Results:

  • Cholangioscopy achieved 85% accuracy in macroscopic diagnosis and 62.5% accuracy for histology-guided biopsies.
  • Macroscopic diagnosis showed 100% sensitivity and 71% specificity; histologic samples had 60% sensitivity and 100% specificity.
  • Successful clearance of stones was achieved in 57.14% of therapeutic cases.

Conclusions:

  • SpyGlass facilitates precise evaluation of indeterminate biliary strictures and simplifies tissue acquisition.
  • Further studies and increased case numbers are required to align diagnostic sensitivity and specificity with international standards.
  • SpyGlass-guided electrohydraulic lithotripsy offers an alternative for challenging bile duct stones.
