Interstitial lasertherapy (ILT) is one of the percutaneous thermal procedures allowing the ablation of primary or secondary hepatic lesions. This technique can be performed without general anaesthesia, since the patient is completely painless, in spite of the high temperatures reached, because there are no sensitive fibers around the lesion. This study includes patients with small hepatocarcinomas (< 2 cm) non peripherically sited, far from the gallbladder and the hepatic hilum. Twenty patients suffering from 24 cirrhotic hepatocarcinomas (two patients showed two nodules) have been enrolled for the present study. Mean diameter of lesions was 1,8 cm (1,3- 2 cm). One or more 21 G (length 20 cm) Chiba's needles were inserted under sonographic view into the lesions. The laser energy was switched on at 4 Watts for 4-6 minutes, until an amount of energy of 900-1800 Joule was reached. All the patients were discharged 48 hours after the procedure. Triphasic CT-scan with contrast were performed 7 to 14 days after ILT, in order to check its efficacy. CT-scan showed complete necrosis in all the nodules ranging from 1,5 to 3 cm. All the patients received only one ILT session, whose longest duration was 20 minutes. No major complications occurred. ILT of small hepatocarcinomas is a safe, efficient procedure, also feasible without anaesthesia. Differently from percutaneous radiofrequency, in fact, it shows the advantage of less pain, that can avoid the need for general anaesthesia.
