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.

Cholecystitis01:20

Cholecystitis

Cholecystitis is inflammation of the gallbladder, most commonly caused by obstruction of the cystic duct. This blockage prevents bile from draining, leading to gallbladder distension, inflammation, and potentially serious complications. This condition may present acutely or chronically and can happen with or without gallstones.EtiologyAbout 95% of cholecystitis cases are calculous, caused by gallstones blocking the cystic duct, leading to bile accumulation and inflammation of the gallbladder...

Imaging Studies V: Intravenous Urography and Retrograde Pyelography

IntroductionIntravenous Urography (IVU) and Retrograde Pyelography (RP) are important diagnostic imaging techniques used to evaluate the urinary system. These methods help identify structural abnormalities, obstructions, and functional issues in the kidneys, ureters, and bladder. Both procedures use iodine-based contrast media to enhance the visibility of urinary tract structures on X-ray images, though they differ in their methods and indications.1.

Appendicitis-II: Diagnostic Studies and Management

Diagnosing and managing appendicitis requires a structured and comprehensive approach that spans from initial assessment to postoperative care. Here is an overview of the process:
Diagnosing Appendicitis
It requires a multifaceted approach, starting with a detailed physical examination to pinpoint the location and nature of the pain and identify any associated symptoms. Laboratory tests play a crucial role. A complete Blood Count (CBC) typically reveals leukocytosis (an increased number of...

Acute Pyelonephritis II: Diagnostic Studies and Management

Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...

Area of Science:

  • Radiology
  • Gastroenterology
  • Interventional Radiology

Background:

  • Recurrent pyogenic cholangitis (RPC) is a biliary tract disease characterized by recurrent bacterial infections.
  • Its incidence is rising in Western populations, necessitating increased awareness among clinicians.
  • Understanding the characteristic imaging findings is crucial for timely diagnosis and management.

Purpose of the Study:

  • To describe the imaging features of RPC across various modalities.
  • To review the role of interventional radiology in managing RPC.
  • To enhance radiologists' familiarity with RPC diagnosis and interventional guidance.

Main Methods:

  • Sonography (ultrasound)
  • Computed Tomography (CT)
  • Magnetic Resonance cholangiopancreatography (MRCP)
  • Endoscopic Retrograde Cholangiopancreatography (ERCP)

Main Results:

  • Detailed descriptions of sonographic, CT, MRCP, and ERCP findings in RPC are presented.
  • The utility of each imaging modality in diagnosing RPC is discussed.
  • The integration of imaging findings with interventional procedures is highlighted.

Conclusions:

  • RPC is a complex condition with increasing prevalence globally.
  • Radiologists play a vital role in diagnosing RPC through various imaging techniques.
  • Imaging serves as a critical guide for interventional radiology in managing RPC.
