Summary Background Morphological, haemodynamic and clinical stages of cirrhosis have been proposed, although no definite staging system is yet accepted for clinical practice. Aim To investigate whether clinical complications of cirrhosis may define different prognostic disease stages. Methods Analysis of the database from a prospective inception cohort of 494 patients. Decompensation was defined by ascites, bleeding, jaundice or encephalopathy. Explored potential prognostic stages: 1, compensated cirrhosis without oesophago‐gastric varices; 2, compensated cirrhosis with varices; 3, bleeding without other complications; 4, first nonbleeding decompensation; 5, any second decompensating event. Patient flow across stages was assessed by a competing risks analysis. Results Major patient characteristics were: 199 females, 295 males, 404 HCV+, 377 compensated, 117 decompensated cirrhosis. The mean follow‐up was 145 ± 109 months without dropouts. Major events: 380 deaths, 326 oesophago‐gastric varices, 283 ascites, 158 bleeding, 146 encephalopathy, 113 jaundice, 126 hepatocellular carcinoma and 19 liver transplantation. Patients entering each prognostic stage along the disease course were: 202, stage 1; 216, stage 2; 75 stage 3; 206 stage 4; 213 stage 5. Five‐year transition rate towards a different stage, for stages 1–4 was 34.5%, 42%, 65% and 78%, respectively (P < 0.0001); 5‐year mortality for stages 1–5 was 1.5%, 10%, 20%, 30% and 88% respectively (P < 0.0001). An exploratory analysis showed that this patient stratification may configure a prognostic system independent of the Child–Pugh score, Model for End Stage Liver Disease and comorbidity. Conclusion The development of oesophago‐gastric varices and decompensating events in cirrhosis identify five prognostic stages with significantly increasing mortality risks.

After liver transplantation, the most common biliary complication is the anastomotic stricture, which is followed by biliary leakage. Studies have focused on the endoscopic treatment of biliary complications in transplanted patients with duct-to-duct reconstruction, showing a success rate of 70% to 80% after orthotopic liver transplantation and of 60% after living-related liver transplantation. Once the endoscopic approach fails, surgical treatment with a Roux-en-Y choledochojejunostomy is the sole alternative treatment. The aim of this prospective observational study was to analyze the efficacy and safety of fully covered self-expandable metallic stents for the treatment of posttransplant biliary stenosis and leaks in patients in whom conventional endoscopic retrograde cholangiopancreatography (ERCP) failed. From January 2008 to January 2009, 16 patients met the criteria of endoscopic treatment failure, and instead of surgery, a fully covered stent was placed. All patients had at least 6 months of follow-up (mean follow-up of 10 months). After removal, 14 patients showed immediate resolution of both the biliary stenosis and leak. After a mean of 10 months of follow-up, only 1 patient showed biliary stenosis recurrence. No major complications occurred in any of the patients, except for stent migration in 6 patients, although these presented with no clinical consequences. In conclusion, in patients not responding to standard endoscopic treatment, the placement of fully covered metal stents is a valid alternative to surgery. A cost analysis should be performed in order to evaluate whether to treat transplanted patients suffering from biliary complications with covered self-expandable metallic stent placement as first-line therapy. Liver Transpl 15: [1493][1494][1495][1496][1497][1498] 2009 Biliary complications are the most frequent complications after liver transplantation. Available data show a rate of biliary complications in transplant recipients ranging from 8% to 35%. This complication rate is higher for living-related liver transplantation (LRLTx) versus orthotopic liver transplantation (OLTx).1,2 Biliary complications include strictures, biliary leaks, stones or debris, and Oddi dysfunction. The most common biliary complication is the anastomotic stricture, which is followed by biliary leakage, although patients often develop more than 1 complication. 3Depending on the type of surgical biliary reconstruction (ie, choledochojejunostomy or duct-to-duct anastomosis), biliary complications can be treated by percutaneous transhepatic cholangiography or by endoscopic retrograde cholangiopancreatography (ERCP). ERCP is currently considered the diagnostic gold standard for patients with duct-to-duct anastomosis because it allows a direct approach for interventional procedures.2 Several studies have evaluated the endoscopic treatment of biliary complications in patients with duct-to-duct reconstruction and have shown a success rate of approxAbbreviations: ALT, alanine aminotransferase; ERCP, endoscopic retrograde c...

A comparative food ethnobotanical study was carried out in twenty-one local communities in Italy, fourteen of which were located in Northern Italy, one in Central Italy, one in Sardinia, and four in Southern Italy. 549 informants were asked to name and describe food uses of wild botanicals they currently gather and consume. Data showed that gathering, processing and consuming wild food plants are still important activities in all the selected areas. A few botanicals were quoted and cited in multiple areas, demonstrating that there are ethnobotanical contact points among the various Italian regions (Asparagus acutifolius, Reichardia picroides, Cichorium intybus, Foeniculum vulgare, Sambucus nigra, Silene vulgaris, Taraxacum officinale, Urtica dioica, Sonchus and Valerianella spp.). One taxon (Borago officinalis) in particular was found to be among the most quoted taxa in both the Southern and the Northern Italian sites.However, when we took into account data regarding the fifteen most quoted taxa in each site and compared and statistically analysed these, we observed that there were a few differences in the gathering and consumption of wild food plants between Northern and Southern Italy. In the North, Rosaceae species prevailed, whereas in the South, taxa belonging to the Asteraceae, Brassicaceae, and Liliaceae s.l. families were most frequently cited. We proposed the hypothesis that these differences may be due to the likelihood that in Southern Italy the erosion of TK on wild vegetables is taking place more slowly, and also to the likelihood that Southern Italians' have a higher appreciation of wild vegetables that have a strong and bitter taste.A correspondence analysis confirmed that the differences in the frequencies of quotation of wild plants within the Northern and the Southern Italian sites could be ascribed only partially to ethnic/cultural issues. An additional factor could be recent socio-economic shifts, which may be having a continued effort on people's knowledge of wild food plants and the way they use them.Finally, after having compared the collected data with the most important international and national food ethnobotanical databases that focus on wild edible plants, we pointed out a few uncommon plant food uses (e.g. Celtis aetnensis fruits, Cicerbita alpine shoots, Helichrysum italicum leaves, Lonicera caprifolium fruits, Symphytum officinale leaves), which are new, or have thus far been recorded only rarely.

Despite the noteworthy migration rate, FCSEMSs should be considered effective for refractory benign biliary strictures. Further studies are needed to assess their role as a first approach in the management of BBS.
