Summary
A novel biphasic solvent effectively dissolved or reduced the size of large common bile duct stones in most patients, offering a less invasive treatment option. This approach demonstrated a high success rate, with minimal toxic side effects observed.
Area of Science:
- Gastroenterology
- Endoscopic procedures
- Pharmacology
Context:
- Large common bile duct stones pose a challenge for endoscopic removal.
- Existing treatments may be invasive or have limitations for large calculi.
Purpose:
- To evaluate a new biphasic multicomponent solvent for dissolving large biliary duct stones (15-35 mm).
- To assess the efficacy and safety of this solvent in patients unsuitable for standard endoscopic removal.
Summary:
- 39 patients with large common bile duct stones were treated with continuous, alternating infusion of two solvent mixtures.
- 10 patients (25.6%) experienced complete stone dissolution within 13-24 hours.
- 25 patients (64.1%) had stones reduced in size for successful basket extraction.
- 4 patients required surgery or endoscopic stenting due to lack of stone size change.
- Mild side effects like duodenitis, abdominal pain, nausea, and diarrhea were noted.
Impact:
- This solvent therapy offers a promising alternative for managing large bile duct stones, potentially reducing the need for surgery.
- The study highlights the feasibility of minimally invasive solvent-based dissolution for complex biliary stone cases.
- Further research may optimize solvent composition and delivery for improved outcomes and patient tolerance.
