- Continuous innovation enhances endoscopic capabilities in managing these conditions.
Purpose of the Study:
- To review the latest advancements in biliary endoscopy over the past year.
- To highlight key studies and emerging trends in endoscopic approaches to biliary diseases.
Main Methods:
- Focused review of recent literature on biliary endoscopy.
- Selection of pivotal studies on endoscopic retrograde cholangiopancreatography, cholangioscopy, and photodynamic therapy.
Main Results:
- Endoscopic retrograde cholangiopancreatography shows enhanced utility in evaluating biliary strictures.
- Cholangioscopy, photodynamic therapy for cholangiocarcinoma, and biliary stent technology have demonstrated significant progress.
Conclusions:

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 to...
