Summary

Nonsurgical treatments for complicated bile duct stones, including chemical litholysis and extracorporeal shockwave lithotripsy (ESWL), offer effective options. Successful stone dissolution was achieved in most patients, with surgery or ESWL used for refractory cases.

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.
