Aims of this retrospective study were to analyze the efficacy and safety of percutaneous ethanol injection (PEI) and radiofrequency ablation (RFA) in cirrhotic patients with hepatocellular carcinoma (HCC) submitted to orthotopic liver transplantation (OLT). We studied 40 patients undergoing OLT in whom 46 HCC nodules had been treated with PEI (13 nodules), RFA (30 nodules), or PEI+RFA (3 nodules). Child-Turcotte-Pugh class was A in 18 cases, B in 18, and C in 4. The mean waiting time for OLT was 9.5 months. The effectiveness of ablation techniques was evaluated by histological examination of the explanted livers. Complete necrosis was found in 19 nodules (41.3%), partial or absent necrosis in 27 nodules (58.7%). Among the 30 nodules treated by RFA, 14 were completely necrotic (46.7%) and 16 demonstrated partial necrosis (53.3%). Considering the 13 neoplasms undergoing PEI, 3 nodules showed complete necrosis (23.1%), 6 partial necrosis (46.1%), and 4 absent necrosis (30.8%). The rate of complete necrosis was 53.1% for nodules smaller than 3 cm and 14.3% for larger lesions ( P = 0.033) but increased to 61.9% when considering only the lesions smaller than 3 cm treated by RFA. During the follow up, HCC recurred in 3 patients treated by PEI. No cases of HCC recurrence at the abdominal wall level were recorded. Percutaneous ablation procedures are effective treatments in cirrhotic patients with HCC submitted to OLT and are not associated to an increased risk of tumor recurrence. RFA provides complete necrosis in most nodules smaller than 3 cm, and appears to be the best treatment option in these cases.

A retrospective data analysis on liver transplantation for Wilson's disease (WD) was performed among Italian Liver Transplant Centers. Thirty-seven cases were identified. The main indication for liver transplantation was chronic advanced liver disease in 78% of patients. Mixed hepatic and neuropsychiatric symptoms were recorded in 32.3%. Eight patients presented with fulminant liver failure; 44.8% were on medical treatment. Patient and graft survival at 3 months, 12 months, 3 years, 5 years, and 10 years after transplantation were, respectively, 91.8%, 89.1%, 82.9%, 75.6%, and 58.8%, and 85.3%, 83.0%, 77.1%, 70.3%, and 47.2%. Neurological symptoms significantly improved after orthotopic liver transplantation (OLT), but the survival of patients with mixed hepatic and neuropsychiatric involvement was significantly lower than in patients with liver disease alone ( P = 0.04). WD characterized by hepatic involvement alone is a rare but good indication for liver transplantation when specific medical therapy fails. Patients with neuropsychiatric signs have a significantly shorter survival even though liver transplantation has a positive impact on neurological symptoms. In conclusion, a combination of hepatic and neuropsychiatric conditions deserves careful neurological evaluation, which should contraindicate OLT in case of severe neurological impairment.

Gastrointestinal perforations and post-surgical fistulas are dreaded complications that dramatically increase morbidity and mortality. A new endoscopic over-the-scope clip (OTSC) system may be potentially useful for sealing visceral perforations in several clinical settings. We evaluated the advantages and clinical impact of the placement of OTSCs on the management of non-malignant gut leaks in 12 consecutive patients. OTSCs of 9.5 or 10.5 mm were used, according to the diameter of the defect within the wall. The indications for treatment were mainly related to post-surgical fistulas. Healing of the fistula was assessed by endoscopic or radiological means, and failed only once. No OTSC-related complications occurred. Endoscopic closure of perforations and post-surgical fistulas with the OTSC system is a simple and minimally invasive technique. This approach, when feasible, may be less expensive and more advantageous than a surgical approach.
