Hepatic cystic echinococcosis：Percutaneous treatment as an outpatient procedure

摘要

Objective:To demonstrate utility and safety of the puncture aspiration injection and reaspiration (PAIR) technique for outpatients.Methods:Percutaneous treatment withUS guidance was applied to33 patients for44 cysts.Patients treated with thePAIR technique, were outpatients. PAIR and catheterization technique were evaluated for efficacy and safety of procedure and complication rates.Results:Thirty-five of44 cysts were treated with thePAIR and9 of44 were treated with the catheterization technique.The success rate of the cystsGharbi type1(CE1) and type2(CE3a) treated with thePAIR technique was100%.In the follow up of9 cysts treated with the catheterization technique,2 of them(22%) developed cyst infection and1(11%) developed a biliary fistula.Conclusions:ThePAIR technique was found to be an effective and safe approach in order to treatGharbi type1 and type2 cysts percutaneously for outpatients.It has a very low complication rate in comparison with the catheterization technique.So every effort should be made to finish the treatment withPAIR technique.
