Endoscopic Procedures V: ERCP

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.

Area of Science:

Gastroenterology and Hepatology
Interventional Endoscopy
Biliary Interventions

Background:

Percutaneous transhepatic cholangioscopy (PTCS) and peroral cholangioscopy (POSC) emerged concurrently.
PTCS is indicated for patients with surgical proximal bowel anatomy unsuitable for POSC.
Limited physician awareness and specialized equipment historically restricted PTCS utilization.

Purpose of the Study:

To provide a comprehensive update on novel interventions performed during PTCS.
To highlight the expanding clinical applications of PTCS.
To review recent advancements in PTCS-specific equipment.

Main Methods:

Literature review of previous and recent studies on PTCS.
Analysis of novel interventions and equipment developments in PTCS.
Synthesis of clinical data on the expanding use of PTCS.

Main Results:

PTCS is increasingly utilized due to advancements in dedicated equipment.
A wider range of interventions can now be performed during PTCS procedures.
Clinical adoption of PTCS has seen a rapid increase.

Conclusions:

Recent developments in PTCS-specific equipment are driving increased clinical use.
PTCS is becoming a more versatile and accessible tool for biliary interventions.
The review updates on the latest interventions feasible with modern PTCS techniques.
