Summary
Single-session alcohol sclerotherapy is a safe and effective treatment for large hepatic cysts. Both 2-hour and 4-hour alcohol retention periods demonstrate comparable therapeutic efficacy in reducing cyst size.
Area of Science:
- Hepatology
- Interventional Radiology
- Gastroenterology
Background:
- Hepatic cysts are fluid-filled sacs in the liver.
- Large hepatic cysts can cause symptoms and complications.
- Sclerotherapy is a minimally invasive treatment option.
Purpose of the Study:
- To evaluate the safety and efficacy of single-session prolonged alcohol sclerotherapy for large hepatic cysts.
- To compare the therapeutic outcomes of 4-hour versus 2-hour alcohol retention techniques.
Main Methods:
- Twenty-seven patients with 31 hepatic cysts underwent alcohol sclerotherapy.
- Patients were divided into two groups: 4-hour (n=18) and 2-hour (n=13) alcohol retention.
- 95% alcohol was used as the sclerosing agent, with a maximum of 200 mL injected.
Main Results:
- Sclerotherapy was well-tolerated, with only one patient in the 2-hour group experiencing an issue.
- Mean cyst volume reduction was high in both groups (98.3% for 4-hour, 97.7% for 2-hour).
- No statistically significant difference in efficacy was observed between the 2-hour and 4-hour retention groups.
Conclusions:
- Single-session prolonged alcohol sclerotherapy is a safe and effective method for treating large hepatic cysts.
- A 2-hour alcohol retention period is as effective as a 4-hour period for hepatic cyst sclerotherapy.
