Papillary cystic neoplasm of the pancreas: a description of two clinical cases.

Papillary-cystic neoplasm of the pancreas is a rare neoplasm principally effecting women in the 2nd and 3rd decades of life. It is considered a low grade malignancy due to it's favourable prognosis and the rarity of metastatic diffusion. Pre-operative diagnosis is rare due to the similarity with other cystic pancreatic lesions. It is for this reason that definitive diagnosis is made at histologic examination of the surgical specimen and total surgical excision represents the therapy of choice. The authors herein describe 2 cases of papillary-cystic neoplasm of the pancreas, thus bringing the total number of cases reported in the world literature to 294.

Orthotopic liver transplantation for alcoholic liver disease: rates of survival, complications and relapse.

BACKGROUND/AIMS: Liver transplantation for alcoholic end-stage liver disease remains controversial at many transplant centers. The aim of the present study was to evaluate the outcome of patients with alcoholic liver disease who underwent liver transplantation at Centro Trapianti, Policlinico S. Orsola, Bologna. METHODOLOGY: We describe the outcomes of 18 alcoholic patients with end-stage liver disease who received orthotopic liver transplants at our center from April, 1986 to February, 1996. The data obtained was compared with that of 114 patients with virus-related cirrhosis selected as transplant controls. An absolute period of abstinence from alcohol consumption for at least six months was required. RESULTS: Regarding the actuarial survival rate and non-fatal post-transplant complications, no significant differences were noted in comparing the non-alcoholic with the alcoholic recipients, except for a higher incidence of Cytomegalovirus infection in the alcoholic group followed-up for more than four months. The alcoholic relapse rate was 27.2%, but only one patient returned to harmful drinking. Seventy-three percent of subjects who were followed-up for at least six months were occupied in gainful employment. Alcoholic relapse did not affect employment status. CONCLUSION: This data demonstrates that liver transplantation for selected patients with end-stage alcohol-related cirrhosis achieves good results in survival, complications and employment status, and it appears difficult to defend an inflexible claim to have demonstrated an absolute long-term abstinence before transplantation when a severe deterioration of liver function is present.

Hepatic resective surgery in cirrhotic patients. Techniques and results of anatomical segmentectomies.

The paper describes the technique of anatomical liver segmentectomies based on the extraparenchymal clamping, at the hepatic hilum, of the afferent vascular pedicles. The resection is started on the liver surface along the demarcation line caused by the ischemia. During parenchymal transection the technique of hemihepatic vascular occlusion has been undertaken. The results obtained with 125 segmentary hepatic resections performed for hepatocellular carcinoma arised on cirrhosis are also reported. The overall operative mortality has been 6.4%. The actuarial 1 and 3 year survivals were 93.3% and 70.4% respectively. Hepatic segmentary resections are recommended for limited hepatic lesions, mainly in well compensated cirrhotic patients.
