Endoscopic Procedures V: ERCP01:26

Endoscopic Procedures V: ERCP

764
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

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 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...

Chronic Bowel Disorders: Introduction01:17

Chronic Bowel Disorders: Introduction

526
Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

Endoscopic Procedures III: Video Capsule Endoscopy01:28

Endoscopic Procedures III: Video Capsule Endoscopy

313
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,...

Area of Science:

  • Gastroenterology and Hepatology
  • Minimally Invasive Endoscopic Procedures
  • Biliary Tract Interventions

Background:

  • Obstructive jaundice presents significant treatment challenges.
  • Traditional management may involve invasive procedures with associated risks.
  • Need for improved diagnostic and therapeutic tools for biliary strictures and large calculi.

Purpose of the Study:

  • To evaluate the efficacy and safety of oral cholangioscopy (SpyGlass system) in treating obstructive jaundice.
  • To assess its application in patients with malignant biliary strictures.
  • To determine its utility in managing choledocholithiasis with large calculi.

Main Methods:

  • A prospective study involving 321 patients with obstructive jaundice.
  • Cholangioscopy (SpyGlass video system) was performed on 18 selected patients.
  • Group 1: 9 patients with malignant biliary strictures underwent stenting. Group 2: 9 patients with large calculi (≥1.2 cm) underwent laser lithotripsy.

Main Results:

  • In malignant biliary strictures, cholangioscopy identified tumor overgrowths, and 55.6% received stenting. Post-procedure pancreatitis occurred in 44.5%, with 44.5% mortality from cancer.
  • For large calculi, cholangioscopy enabled effective visualization and laser lithotripsy, with no intraoperative or postoperative complications reported.
  • The SpyGlass system facilitated targeted interventions in both patient groups.

Conclusions:

  • The SpyGlass system demonstrates effectiveness and safety for diagnosis and treatment in patients with obstructive jaundice.
  • It is particularly valuable for managing extrahepatic biliary strictures and large bile duct calculi.
  • The procedure achieved 100% success in the studied cohort for diagnosis and treatment.
