Diseases of the Liver and Gallbladder

2.5K
Liver and gallbladder diseases are a significant health concern, with prominent conditions including cirrhosis, hepatitis, non-alcoholic fatty liver disease (NAFLD), and gallstones. Jaundice is a common manifestation of liver and biliary disease.
Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not...

Endoscopic Procedures V: ERCP

6.8K
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.

Area of Science:

  • Gastroenterology and Hepatology
  • Minimally Invasive Surgery

Background:

  • Cholangioscopy (CS) is a valuable tool for diagnosing and treating biliary tract conditions.
  • Advancements in endoscope technology have improved CS capabilities.

Purpose of the Study:

  • To review current cholangioscopy technologies.
  • To discuss indications, techniques, efficacy, and complications of CS.

Main Methods:

  • Review of available literature on cholangioscopy systems.
  • Analysis of diagnostic and therapeutic applications.

Main Results:

  • Increased working channel size facilitates tissue sampling and therapeutic interventions like lithotripsy.
  • Slim gastroscopes offer superior image resolution compared to older systems.
  • CS is effective for managing large biliary stones and diagnosing/excluding biliary tumors.

Conclusions:

  • Cholangioscopy is a proven effective modality for complex biliary stone management and tumor evaluation.
  • Fiberoptic cholangioscopes are commercially available, while digital systems are in development.
