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)
PURPOSE Prototypes of Gianturco-Rosch Z-stents coated with polycarbonate urethane (PCU) were placed in the biliary tree of pigs, in order to test their biomechanical behavior, stability, and biocompatibility. METHODS The stents were surgically implanted in the common bile duct of three pairs of pigs, which were killed after 1, 3, and 6 months(More)
Results obtained in 70 patients with neoplastic (primary or metastatic) biliary obstruction and submitted to percutaneous transhepatic biliary drainage indicate the effectiveness of the technique in relieving jaundice, improving general conditions and restoring liver function. In 25.4% of cases, the drainage allowed the patients to undergo surgical(More)
AIMS AND BACKGROUND To evaluate the effectiveness of external radiation therapy (ERT), alone or combined with endoluminal brachytherapy (BRT), following percutaneous transhepatic biliary drainage (PTBD) in the treatment of patients affected by inoperable cholangiocarcinoma. METHODS & STUDY DESIGN From September 1980 to June 1996, 130 jaundiced patients(More)
Some interventional radiological procedures call for unrestricted axial vision and monoplanar fluoroscopy at different angles. We have mounted a fluoroscopic image intensifier in front of the gantry of a CT scanner to assess whether the combination would be useful. This link-up has been tested in a variety of situations and, even with the shortcomings of(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)
