Summary
Intra-corporeal laser lithotripsy (ICL) successfully cleared bile ducts in 87.5% of patients with complex gallstones when other methods failed. This treatment is effective for difficult biliary lithiasis, with low laser-related complications.
Area of Science:
- Gastroenterology
- Endoscopic Surgery
- Biliary Tract Interventions
Background:
- Choledocholithiasis and intra-hepatic lithiasis pose significant clinical challenges.
- Previous treatments like mechanical, extra-corporeal, and electrohydraulic lithotripsy can be ineffective for complex or large stones.
Purpose of the Study:
- To evaluate the efficacy and safety of intra-corporeal laser lithotripsy (ICL) for patients with complex biliary lithiasis.
- To assess outcomes in patients where standard lithotripsy methods had previously failed.
Main Methods:
- A cohort of 16 patients (mean age 72) with difficult biliary stones underwent ICL.
- Various endoscopic approaches were used, including choledochoscopy, retrograde cholangioscopy, and trans-hepatic cholangioscopy.
- ICL was performed when other lithotripsy techniques failed.
Main Results:
- Successful bile duct clearance was achieved in 14 out of 16 patients (87.5%) after an average of 1.66 sessions.
- No mortality or laser-related morbidity occurred.
- Endoscopy-related morbidity was 12.5% (minor) and 6.25% (major), with complications linked to preceding maneuvers, not the laser itself.
Conclusions:
- Intra-corporeal laser lithotripsy is a valuable, albeit expensive and rarely indicated, option for selected patients with complex biliary lithiasis.
- It offers complete relief for challenging gallstone cases.
- The safety profile is favorable, with complications primarily associated with the endoscopic access rather than the lithotripsy procedure.
