EDAP piezoelectric shock wave lithotripsy for gallbladder stones
Chinese Medical Journal
|March 1, 1993
Summary
Extracorporeal shock wave lithotripsy combined with ursodeoxycholic acid effectively treats gallbladder stones. This combination therapy showed higher success rates for smaller, solitary stones, with no serious complications observed.
Area of Science:
- Gastroenterology
- Medical Technology
- Pharmacology
Background:
- Gallbladder stones pose a significant health concern.
- Current treatment options for gallstones have limitations.
- Non-invasive treatment modalities are sought after.
Purpose of the Study:
- To evaluate the efficacy of Extracorporeal Shock Wave Lithotripsy (ESWL) combined with oral ursodeoxycholic acid (UDCA) for treating gallbladder stones.
- To compare treatment outcomes based on stone characteristics and patient groups.
Main Methods:
- ESWL combined with oral UDCA was administered to 1055 patients with gallbladder stones.
- Patients were categorized into two groups based on stone size and number.
- Follow-up was conducted for over 1 year for 926 patients.
Main Results:
- Stone fragmentation rates were high in both groups (96.2% in Group I, 94.1% in Group II).
- Gallstone dissolution rates were significantly higher in Group I (solitary stones ≤20mm) compared to Group II.
- Treatment was most effective for solitary stones ≤20mm; no serious complications were reported.
Conclusions:
- The combined therapy of ESWL and UDCA is a safe and effective treatment for gallbladder stones.
- Treatment efficacy is positively correlated with smaller, solitary stones.
- Further research is needed to optimize treatment outcomes and prevent recurrence.
