Endoscopic retrograde cholangiopancreatography (ERCP) has evolved from a diagnostic tool to a vital therapeutic intervention for biliary disorders. Advanced techniques and future innovations promise expanded applications in diagnosing and treating complex pancreaticobiliary conditions.
Area of Science:
- Gastroenterology
- Endoscopic Surgery
Background:
- Endoscopic retrograde cholangiopancreatography (ERCP) was initially developed for diagnosis but has advanced significantly.
- It is now a key therapeutic intervention for various biliary disorders, including obstructions.
Purpose of the Study:
- To review current endoscopic biliary interventions.
- To discuss emerging and future interventional techniques in pancreaticobiliary medicine.
Main Methods:
- Discussion of established ERCP techniques for biliary obstruction management.
- Exploration of adjunctive methods like endoscopic ultrasound (EUS) with fine needle aspiration and radiofrequency ablation.
- Overview of advanced bile duct access strategies and nonsurgical gallbladder drainage.
Main Results:
- ERCP is effective for managing benign and malignant biliary obstructions.
- EUS aids in diagnosing and intervening on pancreaticobiliary lesions.
- Various techniques exist for challenging bile duct access and gallbladder drainage.
Conclusions:
- ERCP and EUS are crucial tools for diagnosing and treating pancreaticobiliary diseases.
- Future advancements may include robotic-assisted procedures and direct intrapancreaticobiliary drug delivery.
