Endoscopic Procedures V: ERCP01:26

Endoscopic Procedures V: ERCP

1.2K
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.

Urologic Endoscopic Procedure: Cystoscopic Examination

709
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...

Endoscopic Procedures I: Esophagogastroduodenoscopy

449
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 Thoracoscopy01:30

Endoscopic Studies I: Bronchoscopy and Thoracoscopy

305
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 III: Video Capsule Endoscopy01:28

Endoscopic Procedures III: Video Capsule Endoscopy

388
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,...

Summary
This summary is machine-generated.

Percutaneous biliary endoscopy offers an underutilized approach for diagnosing and treating biliary pathology, especially when endoscopic retrograde cholangiopancreatography is not feasible. Interventional radiologists can leverage this technique for complex cases, considering key clinical and procedural factors.

Area of Science:

  • Interventional Radiology
  • Gastroenterology
  • Hepatobiliary Surgery

Background:

  • Biliary endoscopy is not widely used by interventional radiologists.
  • It has potential as an adjunctive diagnostic and therapeutic tool for biliary diseases.
  • It is especially useful in patients with surgically altered anatomy or failed endoscopic retrograde cholangiopancreatography.

Purpose of the Study:

  • To review the clinical evaluation, perioperative management, and procedural techniques of percutaneous biliary endoscopy.
  • To highlight the potential of percutaneous biliary endoscopy as an adjunctive tool for interventional radiologists.

Main Methods:

  • Review of clinical evaluation parameters.
  • Discussion of perioperative management strategies.
  • Detailed description of percutaneous biliary endoscopy techniques.

Main Results:

  • Percutaneous biliary endoscopy can be an effective alternative when standard endoscopic retrograde cholangiopancreatography is not possible.
  • Careful consideration of preoperative clinical and technical factors is crucial for successful intervention.

Conclusions:

  • Percutaneous biliary endoscopy is a valuable technique for managing complex biliary pathology.
  • Interventional radiologists can expand their role in hepatobiliary interventions using this method.
