Ultrasound II: Endoscopic Ultrasound and FibroScan01:25

Ultrasound II: Endoscopic Ultrasound and FibroScan

266
Endoscopic Ultrasound (EUS) and FibroScan are valuable diagnostic tools in gastroenterology and hepatology, each with specific applications and techniques.
Endoscopic Ultrasound (EUS):

Endoscopic Procedures III: Video Capsule Endoscopy01:28

Endoscopic Procedures III: Video Capsule Endoscopy

410
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 V: ERCP01:26

Endoscopic Procedures V: ERCP

1.3K
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

478
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:

Ultrasound I: Abdominal Ultrasonography01:20

Ultrasound I: Abdominal Ultrasonography

566
Introduction:
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...

Urologic Endoscopic Procedure: Cystoscopic Examination01:28

Urologic Endoscopic Procedure: Cystoscopic Examination

804
Meaning of Cystoscopic Examination:Cystoscopy is an essential diagnostic tool in urology that is used to assess the structure and function of the genitourinary system. It provides a direct view of the urethra, bladder, and, in some cases, the ureteral openings. This procedure helps detect structural abnormalities, infections, cancers, and blockages in the urinary tract. There are two types of cystoscopy:Flexible cystoscopy is commonly performed in outpatient settings due to its less invasive...

Area of Science:

  • Gastroenterology
  • Minimally Invasive Surgery
  • Medical Technology

Background:

  • Advancements in linear echoendoscopes with larger channels.
  • Development of new tools and devices for endoscopic ultrasound (EUS).

Purpose of the Study:

  • To review recent advances in interventional endoscopic ultrasound (INVEUS) techniques.
  • Evaluate current EUS-guided transluminal interventions.

Main Methods:

  • Review of EUS-guided interventions including drainage, neurolysis, ablation, and more.
  • Classification of interventions based on evidence: established vs. experimental, standardized vs. non-standardized.

Main Results:

  • EUS-guided interventions cover a wide range of applications for pancreatic, biliary, and peri-gastrointestinal structures.
  • Some interventions are widely accepted, while others have limited evidence.
  • INVEUS is a viable alternative to surgery, offering faster recovery, shorter hospital stays, and lower costs.

Conclusions:

  • Interventional endoscopic ultrasound (INVEUS) is a rapidly evolving field with significant clinical impact.
  • EUS-guided techniques offer advantages over traditional surgical approaches.
  • Further research is needed for less-established INVEUS procedures.
