Liver hydatid disease: long-term results of percutaneous treatment
1Department of Radiology, Hacettepe University, School of Medicine, Ankara, Turkey.
Insights
Percutaneous treatment effectively reduced liver hydatid cyst size by an average of 83%. This minimally invasive approach demonstrated long-term safety and efficacy in selected patients, with minimal complications.
Area of Science:
- Hepatology
- Parasitology
- Interventional Radiology
Background:
- Liver hydatid cysts, caused by Echinococcus granulosus, pose a significant health challenge.
- Traditional surgical management can be invasive with associated morbidity.
- Percutaneous techniques offer a less invasive alternative for managing parasitic liver cysts.
Purpose of the Study:
- To assess the long-term effectiveness and safety of percutaneous treatment for liver hydatid cysts.
- To evaluate the outcomes of percutaneous cyst ablation using hypertonic saline and/or absolute alcohol.
Main Methods:
- A cohort of 31 patients with 57 liver hydatid cysts underwent percutaneous treatment.
- Cysts were treated using hypertonic saline (15% NaCl) and/or absolute alcohol under sonographic and/or fluoroscopic guidance.
- Patients were monitored for cyst size reduction, complications, and recurrence.
Main Results:
- Significant cyst volume reduction (mean 83%, range 18%-99%) was observed.
- Cyst wall thickening and pseudotumor formation were noted during follow-up.
- No mortality or abdominal dissemination occurred; major complications included cavity infection, hypersensitivity, and biliary fistula. One recurrence was noted.
Conclusions:
- Percutaneous treatment of liver hydatid cysts is a safe and effective method in selected patients.
- The procedure leads to substantial cyst volume reduction and favorable long-term outcomes.
- Careful patient selection and monitoring are crucial for optimal results.
Purpose:
To evaluate the long-term effectiveness of percutaneous treatment of liver hydatid cysts.
Materials And Methods:
Thirty-one patients (19 female patients and 12 male patients; age range, 8-78 years; mean age, 41 years) with 57 liver hydatid cysts underwent percutaneous treatment. The cysts were treated with hypertonic saline (15% NaCl) and/or absolute alcohol. Sonographic and/or fluoroscopic guidance was used.
Results:
Repeated sonography revealed a gradual decrease in cyst size. Volume reduction was 18%-99% (mean, 83%). With the disappearance of the fluid component, pseudotumor appearance occurred. In all treated cases, the cyst wall became irregular and thicker during follow-up. No mortality occurred. No abdominal dissemination was encountered during follow-up. Major complications were infection of the cavity, hypersensitivity reaction, and development of biliary fistula. One cyst recurred 11 months after primary drainage.
Conclusion:
Long-term results indicate that percutaneous treatment of liver hydatid cysts is an effective and safe method in selected cases.
