Treatment of symptomatic hepatic cysts by percutaneous instillation of minocycline hydrochloride.
ABSTRACT Nine patients with 16 symptomatic nonneoplastic congenital hepatic cysts were treated prospectively by ultrasonically guided percutaneous minocycline hydrochloride injection, and the usefulness of this treatment was evaluated. Seven of the patients had multiple hepatic cysts, and two solitary cysts. All the patients were women, ranging in age from 36 to 81 years. After cystic fluid had been aspirated with a 21-gauge PTC needle, minocycline hydrochloride was injected into all the cysts. The minocycline hydrochloride was dissolved in saline at a concentration of 200 mg in 9 ml, and mixed with 1 ml of 2% mepivacaine hydrochloride. The total quantity of minocycline hydrochloride injected varied from 100 mg to 1200 mg per hepatic cyst, depending on its size. Total or subtotal regression of the cysts was observed in all patients during follow-up periods ranging from 15 to 35 months. Seven patients became symptom-free, one showed symptom reduction, and one showed no change in symptoms. Minor side effects, eg, transient abdominal pain, slight right shoulder pain, and temperature elevation, were noted in three patients respectively. On the basis of these results, we conclude that ultrasonically guided percutaneous minocycline hydrochloride injection is useful for the treatment of symptomatic hepatic cysts.

ABSTRACT: We describe a patient with autosomal dominant polycystic kidney disease who was successfully managed for severe abdominal distension, impaired liver function and a portosystemic shunt by interventional therapies. The patient's intra-hepatic portal vein was compressed and narrowed by multiple liver cysts, which resulted in a decrease of the portal blood flow and portal hypertension due to a huge gastro-renal shunt. These haemodynamic changes were assumed to contribute to insufficient protein synthesis in the liver. Therefore, we first repeatedly performed minocycline hydrochloride instillations to treat the multiple liver cysts. Then, we conducted a partial splenic embolization to prevent elevation of the portal vein pressure prior to balloon-occluded retrograde transvenous obliteration which was performed to increase the portal blood flow. The portal blood flow markedly increased, and protein synthesis in the liver also recovered and the clinical symptoms improved. The patient has been monitored for more than two years up to the present and her liver function parameters have remained within the normal range. Renal insufficiency is known to be a major prognostic factor in autosomal dominant polycystic kidney disease. In some cases, however, liver involvement with multiple cysts may result in a fatal outcome. In such cases, interventional therapies, as provided to this patient, should be considered.European Journal of Gastroenterology & Hepatology 12/2000; 13(1):75-78. · 1.92 Impact Factor

ABSTRACT: Benign liver tumors are common. They do not spread to other areas of the body, and they usually do not pose a serious health risk. In fact, in most cases, benign liver tumors are not diagnosed because patients are asymptomatic. When they are detected, it's usually because the person has had medical imaging tests, such as an ultrasound (US), computed tomography (CT) scan, or magnetic resonance imaging (MRI), for another condition. A search of the literature was made using cancer literature and the PubMed, Scopus, and Web of Science (WOS) database for the following keywords: "hepatic benign tumors", "hepatic cystic tumors", "polycystic liver disease", "liver macroregenerative nodules", "hepatic mesenchymal hamartoma", "hepatic angiomyolipoma", "biliary cystadenoma", and "nodular regenerative hyperplasia". Hepatocellular carcinoma (HCC) is one of the most common malignant tumors in some areas of the world; there is an increasing incidence worldwide. Approximately 750,000 new cases are reported per year. More than 75 % of cases occur in the Asia-Pacific region, largely in association with chronic hepatitis B virus (HBV) infection. The incidence of HCC is increasing in the USA and Europe because of the increased incidence of hepatitis C virus (HCV) infection. Unlike the liver HCC, benign tumors are less frequent. However, they represent a chapter always more interesting of liver disease. In fact, a careful differential diagnosis with the forms of malignant tumor is often required in such a way so as to direct the patient to the correct therapy. In conclusion, many of these tumors present with typical features in various imaging studies. On occasions, biopsies are required, and/or surgical removal is needed. In the majority of cases of benign hepatic tumors, no treatment is indicated. The main indication for treatment is the presence of significant clinical symptoms or suspicion of malignancy or fear of malignant transformation.Journal of Gastrointestinal Cancer 02/2014;
