Percutaneous US-guided combined ethanol and tetracycline injection for treating symptomatic simple and hydatid hepatic cysts

Combined ethanol and tetracycline sclerotherapy was associated with fewer sessions than ethanol sclerotherapy (P = ≤0.001) and higher rate of sustained cyst size reduction on follow up (P = ≤0.001). Also second arm was associated with less pain than alcohol alone due to the beneficial effect of tetracycline. Conclusion: combined ethanol and tetracycline seems to be more effective, non expensive, more sustained action and more comfortable to our patients than single ethanol use.
