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.

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 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...

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 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:

Area of Science:

Gastroenterology and Hepatology
Minimally Invasive Surgery

Background:

Cholangioscopy is a complementary tool for biliary disease evaluation, offering direct bile duct visualization.
Traditional cholangioscopy faced challenges including scope fragility, poor maneuverability, and the need for multiple operators, limiting its widespread adoption.

Purpose of the Study:

To review the role and advancements in cholangioscopy for diagnosing and treating biliary diseases.
To highlight how recent innovations address previous technical limitations.

Main Methods:

Review of existing literature on cholangioscopy techniques and outcomes.
Discussion of technological advancements in cholangioscopy equipment.

Main Results:

Direct visualization is a key advantage of cholangioscopy over indirect imaging.
Innovations include electronic video cholangioscopes and single-operator systems.
These advancements aim to overcome previous technical hurdles.

Conclusions:

Recent innovations are enhancing the feasibility and utility of cholangioscopy.
Improved systems promise to increase the diagnostic and therapeutic efficacy of cholangioscopy in managing biliary conditions.
