Efficacy and safety of PAIR for cystic echinococcosis: experience on a large series of patients from Bulgaria.

We report our experience with puncture, aspiration, injection, and reaspiration (PAIR) for the treatment of cystic echinococcosis in Bulgaria. PAIR was performed in 230 patients with 348 echinococcal cysts. At 12-month follow-up, 77.

[Radiofrequency ablation of recurrent intrahepatic cholangiocarcinoma: a case report].

A 45-years-old patient with recurrent intrahepatic cholangiocarcinoma 3 years after resection is described. 2 sessions of percutaneous radiofrequency ablation (RFA) were performed and complete destruction of the tumor was achieved. The patient was followed-up for 15 months by means of power-Doppler, CT and tumor markers.

[Bolus percutaneous ethanol injections in hepatocellular carcinoma--clinical results].

Aim: To establish the effectiveness of large-volume percutaneous ethanol injection under general anesthesia (Shot-PEI) as a local method for destruction of large hepatocellular carcinoma (HCC).

Patients And Methods: 46 patients with 48 HCC were treated with Shot-PEI. 1-4 sessions per lesion were performed with 12-138 ml ethanol per session.

[Radiofrequency ablation of hepatic metastases: clinical results].

Aim: To establish the effectiveness of radiofrequency ablation in the treatment of metastatic hepatic lesions.

Patients And Methods: 104 pts with 231 metastases were treated with RFA. The volume of achieved destruction was assessed using imaging method and cytology.

[Classifications and prognosis of hepatocellular carcinoma].

In this study are included 78 patients with hepatocellular carcinoma (HCC). In 22 the diagnosis is verified pathologically (obduction), while in the other patients the diagnosis is made by laparoscopy, laparoscopical ultrasonography and morphological verification (through FNAB cytology and/or histology). In 69.
