Problematic bile duct stones: polyvalent treatment

Area of Science:

• Gastroenterology
• Interventional Endoscopy
• Biliary Tract Interventions

Background:

• Nonsurgical treatments for complicated bile duct stones allow tailored therapy based on individual case characteristics, risks, benefits, and costs.
• Effective management of bile duct stones requires careful consideration of stone burden, impaction, and associated biliary pathology.

Purpose of the Study:

• To evaluate the efficacy and outcomes of various nonsurgical treatment modalities for complicated bile duct stones.
• To assess the success rates of chemical litholysis and extracorporeal shockwave lithotripsy (ESWL) in achieving bile duct stone clearance.

Main Methods:

• A study involving 26 patients with complicated bile duct stones treated with diverse techniques, including sequential or alternative approaches.
• Initial treatment predominantly involved chemical litholysis using a monooctanoin and methyl tert-butyl ether mixture.
• Patients with large, impacted, multiple stones, or those with prior biliodigestive anastomosis or Caroli's disease were included.

Main Results:

• Complete stone dissolution was achieved in 9 patients; partial dissolution with subsequent elimination occurred in 8 patients.
• In 7 patients with unsuccessful chemolitholysis, surgical clearance (6 cases) or ESWL was employed.
• Two patients were successfully treated with upfront ESWL and saline washout.

Conclusions:

• Nonsurgical interventions, primarily chemical litholysis and ESWL, demonstrate significant success in managing complicated bile duct stones.
• Alternative or sequential treatments, including surgery, are effective for cases refractory to initial nonsurgical approaches.
• The study highlights the importance of selecting appropriate nonsurgical strategies for optimal patient outcomes in biliary stone management.
