Successful treatment with percutaneous transhepatic alcoholization of a liver abscess in a child with chronic granulomatous disease

Successful transcatheter arterial antimicrobial and steroid therapy for refractory liver abscess in chronic granulomatous disease: A case report and review of literature

Hepatic abscess in chronic granulomatous disease (CGD) is very refractory and frequently requires multiple surgeries with frequent morbidities. Although surgical interventions are often required, patients are often not able to have surgery for various reasons. We present the case of a 21-year-old man with recurrent hepatic abscess in CGD. We could not provide surgical interventions due to the lack of a fluid cavity and the patient's refusal, and therefore we administered transcatheter arterial antimicrobial and steroid therapy. He did not have any exacerbation for more than 18 months after the final transcatheter treatment. This is the first reported case of successful transcatheter arterial antimicrobial and steroid therapy for refractory hepatic abscess in CGD. Although the patient's burden and medical cost were not inconsequential, this case shows that the transcatheter arterial antimicrobial and steroid therapy may be a treatment option for patients who are not candidates for surgical interventions.

Alcoholization of pyogenichepatic abscess with absolute alcohol in Bama minipigs

Pyogenic hepatic abscess (PHA) is a rare, but potentially serious disease. At present, ultrasound-guided or computed tomography-guided percutaneous needle aspiration or catheter drainage is appropriate as a first-line treatment. However, it is difficult to aspirate or drain pus and to select the appropriate antibiotic therapy if the abscess consists of thick pus and polymicrobial confections, or its pathogenic bacterium is multidrug resistant and cryptogenic. Case studies of alcoholization provide a novel method to manage PHA. However, the efficacy and safety of this treatment should be further evaluated. In the present study, the therapeutic efficacy and complications of alcoholization for PHAs in Bama minipigs were investigated. PHAs were prospectively treated by ultrasound-guided percutaneous instillation of absolute alcohol in the abscess cavity. The criteria for considering a successful intervention were met in all minipigs subsequent to alcoholization twice within 14 days. The procedures were well tolerated in all animals, and there were no alcoholic adverse effects or procedure-associated complications. In conclusion, ultrasound-guided percutaneous alcoholization is a safe and effective procedure to manage PHA. The problems of thick pus aspiration and selection of an appropriate antibiotic observed in other treatments were resolved effectively using alcoholization. This technique may reduce the treatment period and possibly become a novel strategy for the management of PHA.
