Percutaneous transhepatic choledochoscopic electrohydraulic lithotripsy for common bile duct stones: experience in
Insights
Percutaneous transhepatic electrohydraulic lithotripsy is a safe option for difficult common bile duct stones. This approach successfully fragmented stones in most high-risk patients when endoscopic methods failed.
Area of Science:
- Gastroenterology
- Interventional Radiology
- Surgical Technology
Background:
- Common bile duct stones pose a significant clinical challenge.
- Traditional endoscopic retrograde cholangiopancreatography (ERCP) may fail for impacted or large stones.
- High-risk patients often have limited treatment options.
Purpose of the Study:
- To evaluate the safety and efficacy of percutaneous transhepatic choledochoscopic electrohydraulic lithotripsy.
- To assess this method as an alternative for patients unsuitable for or failing ERCP.
Main Methods:
- Percutaneous transhepatic choledochoscopic electrohydraulic lithotripsy was performed in four high-risk patients.
- Patients had common bile duct stones not removable by standard duodenoscopic techniques.
- Procedure involved fragmentation and removal of stones via a transhepatic approach.
Main Results:
- Successful fragmentation and removal of common bile duct stones were achieved in three out of four patients.
- The procedure was generally well-tolerated, with no procedural complications reported.
- One patient experienced a fatal outcome due to bronchopneumonia unrelated to the lithotripsy procedure itself.
Conclusions:
- Percutaneous transhepatic choledochoscopic electrohydraulic lithotripsy is a viable alternative for treating difficult common bile duct stones in high-risk patients.
- This method offers a safe and effective nonoperative treatment when endoscopic approaches are unsuccessful.
- Potential drawbacks include the need for multiple maneuvers and a potentially prolonged hospital stay.
Abstract:
Choledochoscopic electrohydraulic lithotripsy was applied through a percutaneous transhepatic approach in four high-risk patients with common bile duct stones that were not extractable by duodenoscopic means. All stones were fragmented and removed from three patients, but one patient died from bronchopneumonia before ductal clearance could be achieved. The procedure was well tolerated, without any complication. The major disadvantage is the multiple maneuvers required and the prolonged hospital stay. Percutaneous transhepatic choledochoscopic electrohydraulic lithotripsy provides a safe and effective alternative for nonoperative treatment of common bile duct stones in high-risk patients when the duodenoscopic approach fails.
