PURPOSE To assess the feasibility of percutaneous transhepatic biliary drainage (PTBD) for the treatment of postsurgical biliary leaks in patients with nondilated intrahepatic bile ducts, its efficacy in restoring the integrity of bile ducts, and technical procedures to reduce morbidity. METHODS Seventeen patients out of 936 undergoing PTBD over a 20-year(More)
Tumor suppressor protein p53 is a positive regulator of MDM2 gene expression and the mdm2 protein can bind to p53, preventing the transactivation of p53 responsive genes, thus mimicking TP53 mutation. The authors looked for alterations that could affect, directly and indirectly, p53 function in 13 patients with extrahepatic cholangiocarcinoma. Molecular(More)
This study evaluated interventional radiological experience in the management of biliary complications of OLT at the National Cancer Institute of Milan. Seventeen patients who had undergone orthotopic liver transplantation in various hospital were referred to our unit with biliary complications. Group I consisted of 8 patients with anastomotic biliary(More)
The accuracy of the double-contrast enema for the diagnosis of polypoid lesions in the presence or absence of diverticula was evaluated by retrospectively reviewing the medical records of 202 patients subjected to examination and endoscopy. Analysis of the data on 215 polypoid lesions showed that (a) the diagnostic accuracy of the examination is not(More)
Sepsis of the biliary tract is often reported after percutaneous transhepatic biliary drainage (PTBD) and is considered a life-threatening condition. The authors studied 39 patients with biliary stenosis (35 with neoplastic stricture and four with benign disease) with the purpose of identifying some factors possibly associated with a higher risk of(More)
BACKGROUND Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) is an innovative approach to peritoneal carcinomatosis. Due to the complexity of the combined procedure, high rates of potentially life-threatening complications have been reported. This is the first report of colobronchial fistula following CRS and HIPEC. CASE(More)
From 1979 to 1982, 1233 symptom-free subjects at high risk for colon cancer because of family history and/or personal history of bowel neoplasia (cancer or adenomatous polyp) were examined with a guaiac test (Hemoccult II) for occult blood in stools. The test was positive (H+) in 98 subjects (7.9%). Endoscopy was subsequently performed on 86% of the H+ and(More)
We provide a refoundation of the symmetric growth equilibrium characterizing the research sector of vertical R&D-driven growth models. We argue that the usual assumptions made in this class of models leave the agents indi¤erent as to where targeting research: hence, the problem of the allocation of R&D investment across sectors is indeterminate.

PURPOSE To evaluate the results of percutaneous balloon dilation of benign bile duct strictures in a series of patients with a long follow-up period. MATERIAL AND METHODS 56 patients with benign bile duct strictures underwent balloon catheter dilation. These patients had strictures of various origins: postsurgical, postlocal not surgical treatments,(More)
