Endoscopic Procedures V: ERCP01:26

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.

Endoscopic Procedures I: Esophagogastroduodenoscopy01:29

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 III: Video Capsule Endoscopy01:28

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...
Endoscopic Procedures II: Colonoscopy01:25

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 Thoracoscopy01:30

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 IV: Sigmoidoscopy and Laproscopy01:26

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...

Area of Science:

  • Gastroenterology and Endoscopy
  • Oncology
  • Interventional Radiology

Background:

  • Biliary endoscopy has advanced significantly with new diagnostic and therapeutic techniques.
  • Current applications include imaging, tissue sampling, and management of biliary tumors and stones.

Purpose of the Study:

  • To review recent advancements in biliary endoscopy.
  • To highlight emerging diagnostic and therapeutic tools for biliary tract diseases.

Main Methods:

  • Review of novel endoscopic techniques for biliary stone management (electrohydraulic and laser lithotripsy).
  • Introduction of advanced diagnostic tools: intraductal ultrasound, confocal laser endomicroscopy, optical coherence tomography.
  • Evaluation of enhanced cytology (digital imaging analysis, FISH) for early tumor detection.
  • Assessment of new cholangioscopes for direct visualization and tissue sampling.
  • Review of palliative treatments for cholangiocarcinoma (photodynamic therapy, brachytherapy) and novel stent technologies.

Main Results:

  • New endoscopic methods improve biliary stone management.
  • Emerging diagnostic tools show promise for undetermined biliary strictures.
  • Advanced cytology and cholangioscopy enhance early diagnosis of biliary tumors.
  • Palliative therapies and drug-eluting stents improve outcomes for non-operable cholangiocarcinoma.

Conclusions:

  • Recent innovations in biliary endoscopy offer improved diagnostic accuracy and therapeutic efficacy.
  • These advancements hold significant potential for managing complex biliary tract conditions, including tumors and strictures.
  • Further research and clinical application of these tools are expected to enhance patient quality of life and survival rates.
