Multifocal Biliary Cystadenocarcinoma of the Liver: CT and Pathological Findings
2006
Biliary cystadenocarcinoma is a rare tumor that originates from the hepatobiliary epithelium. Although this tumor can affect any portion of the biliary tree, intrahepatic location is more common. It is usually a slow growing tumor and often asymptomatic until it reaches a considerable size. The lesion is most often solitary and large when discovered; multiple lesions or metastases within the liver are very rare. A 63-year-old man was referred to our institute for weight loss, abdominal discomfort, worsening bulky symptoms in the right upper abdominal quadrant, and an increase in serum aminotransferases that had been present for several months. Spiral CT of the abdomen demonstrated two lesi…

A New Self-Expanding Nitinol Stent (JoStent SelfX) for Palliation of Malignant Biliary Obstruction: a Pilot Study
2004
Background and Study Aims: The JoStent SelfX is a new biliary uncovered self-expanding nitinol stent. The main advantage of this stent in comparison with the gold standard Wallstent is the minimal shortening (< 10%) that occurs during stent deployment. A prospective feasibility study was conducted to evaluate the method of stent implantation and the stent's short-term efficacy. Patients and Methods: Between April 2001 and December 2002, the JoStent SelfX was implanted in 20 patients with inoperable malignant biliary obstructions, mainly caused by pancreatic cancer (12 of 20). All patients underwent sphincterotomy prior to stent insertion. After implantation, laboratory parameters for choles…
Electrospun Polyhydroxyethyl-Aspartamide-Polylactic Acid Scaffold for Biliary Duct Repair: A Preliminary In Vivo Evaluation
2017
Abstract Tissue engineering has emerged as a new approach with the potential to overcome the limitations of traditional therapies. The objective of this study was to test whether our polymeric scaffold is able to resist the corrosive action of bile and to support a cell's infiltration and neoangiogenesis with the aim of using it as a biodegradable tissue substitute for serious bile duct injuries. In particular, a resorbable electrospun polyhydroxyethyl-aspartamide–polylactic acid (90 mol% PHEA, 10 mol% PLA)/polycaprolactone (50:50 w/w) plate scaffold was implanted into rabbit gallbladder to assess the in vivo effects of the lytic action of the bile on the scaffold structure and then as a tu…
RECURRENT RETROPERITONEAL ABSCESS AFTER BILIARY TRACT SURGERY IN AN ELEDERLY PATIENT: A MINIMALLY INVASIVE NONSURGICAL APPROIACH AND ITS CONSEQUENCES…
2019
Abstract Introduction Hepatic abscess can be defined as an encapsulated collection of suppurative material within the liver parenchyma. Hepatic abscess can be distinguished as pyogenic, amebic, or fungal. Biliary tract disease remains the most common cause of hepatic abscess today, and the most common complications range from pleural effusion, empyema, and bronchohepatic fistula to subphrenic abscess and rupture into the peritoneal cavity, stomach, colon, vena cava, or kidney. A large abscess compressing the inferior vena cava and the hepatic veins may result in Budd-Chiari syndrome. In this report, we present a rare case of hepatic abscess with an unusual evolution that was treated with a …
