1/31. Case report: two cases of biliary papillomatosis with unusual associations.Papillomatosis arising from the biliary tree is a well recognized but rare entity. We encountered two patients with this condition. However, one of them had associated hepatocellular carcinoma and cirrhosis and the other had concomitant recurrent pyogenic cholangitis. To our knowledge, these associations have not been reported before. We, therefore, present these clinical problems and highlight the added difficulty in the management of these patients.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
2/31. Multidisciplinary approach to palliation of obstructive jaundice caused by a central hepatocellular carcinoma.BACKGROUND/AIMS: Obstructive jaundice due to intraductal tumour growth is a rare symptom in association with hepatocellular carcinoma (HCC). methods: We report a 65-year-old white male who was admitted to our department with a 2-week history of progressive jaundice. At laparotomy, the liver showed advanced cirrhosis due to long-standing biliary obstruction. cholangiography confirmed total obstruction of the main bifurcation of the hepatic duct by intraductal tumour growth. Combination treatment with surgical segment III drainage, transcatheter arterial embolization and radioembolization with yttrium-90 resin particles and endoscopic stenting was performed. This form of treatment has never been reported before. RESULTS: With these combined procedures, relief of jaundice and a survival time of 32 months could be achieved. CONCLUSION: The combination of palliative methods may relieve jaundice, ensure a good quality of life and possibly prolong survival in patients with mechanical tumour obstruction of the biliary tree by HCC.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
3/31. Obstructive jaundice caused by hepatocellular carcinoma: detection by endoscopic sonography.Tumor thrombus in the extrahepatic biliary tree is a rare mechanism of obstructive jaundice. We present a patient with a minute hepatocellular carcinoma in the caudate lobe that invaded the common hepatic duct and caused biliary obstruction. Endoscopic sonography showed a tumor thrombus with central echogenicity and a "nodule-in-nodule" pattern and suggested the correct diagnosis.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
4/31. Oncocytic biliary cystadenocarcinoma is a form of intraductal oncocytic papillary neoplasm of the liver.Biliary cystadenocarcinoma with oncocytic differentiation was first reported in 1992. This is a report of a second case. The patient (a 71-year-old man) was admitted to our hospital complaining of abdominal fullness. Multicystic lesions were identified in the left hepatic lobe radiologically. The patient died of peritoneal dissemination of carcinoma 20 months later. At autopsy, the tumor of the left hepatic lobe was found to be composed of adjoining multiple cystic lesions and a solid lesion with infiltration of the hepatic hilus and peritoneal dissemination. Histologically, the multicystic lesions were covered by papillary neoplastic epithelial cells with an eosinophilic granular cytoplasm resembling that of oncocytes and a fine fibrovascular core. The cyst wall was fibrous, but there was no mesenchymal stroma. In the solid lesion and infiltrated areas, acidophilic and granular carcinoma cells formed small glandular or solid cord patterns with much mucin secretion (mucinous carcinoma). Immunohistochemically, carcinoma cells of both components were found to contain many mitochondria and showed the phenotypes of hepatocytes and cholangiocytes. Interestingly, the intrahepatic biliary tree also was invaded by carcinoma cells. This may be a case of intraductal oncocytic papillary neoplasm of the left hepatic lobe followed by secondary cystic dilatation of the affected bile duct.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
5/31. Squamous cell carcinoma arising in a hepatic forgut cyst.We report the second case of squamous cell carcinoma arising in a hepatic foregut cyst (CHFC) in a 40-year-old woman. Microscopically, the lining of the cyst was composed of ciliated columnar epithelium, gastric and squamous epithelium. The squamous epithelium showed areas with dysplastic changes and other areas with carcinomatous transformation. In this congenital lesion, it was not surprising to find squamous and gastric mucosa because oesophagus, stomach, and tracheobronchic tree derive from the embryologic foregut. Squamous carcinoma might develop in a context of inflammation as in biliary cyst. In agreement with the first case described in the literature, this report also suggests that a large-sized symptomatic hepatic cyst should be excised.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
6/31. Hepaticogastrostomy by echo-endoscopy as a palliative treatment in a patient with metastatic biliary obstruction.A palliative hepaticogastrostomy was performed under endoscopic ultrasound guidance in a patient with inoperable hepatic hilar obstruction, creating an anastomosis between the dilated left hepatic duct and the stomach, to relieve symptoms of cholangitis and to allow biliary drainage. This therapeutic procedure was used as an alternative method of drainage of the biliary tree because endoscopic retrograde cholangiopancreatography was not possible and because the percutaneous metallic stent which had been inserted earlier had become occluded (probably by tumor overgrowth). It was a two-step procedure. In the first step a hepatic duct was punctured through the gastric wall with placement of a plastic stent, which created a fistula between them. In a second step a covered, metallic, self-expandable stent was substituted for the plastic stent to maintain the anastomosis and to improve patency over the medium term. The patient's fever was relieved and the bilirubin level fell; the patient remained asymptomatic at the five-months-follow-up.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
7/31. Use of percutaneous drainage to treat hepatic abscess after radiofrequency ablation of metastatic pancreatic adenocarcinoma.Radiofrequency ablation (RFA) is well described in the treatment of primary hepatic malignancies and colorectal carcinoma hepatic metastases. A known complication of RFA is the development of hepatic abscess. The management of hepatic abscesses subsequent to RFA for metastatic disease is not well described. A 49-year-old female with pancreatic adenocarcinoma underwent pancreaticoduodenectomy followed by adjuvant chemoradiation. Following 6 months' treatment, a new liver metastasis was identified. It remained stable for 6 months during additional chemotherapy and thereafter was treated with RFA. Three weeks after RFA, the patient presented with malaise and leukocytosis, and a CT scan demonstrated a large hepatic abscess at the site of the RFA. She remained febrile despite needle aspiration and intravenous antibiotics. A percutaneous drain was placed and the symptoms resolved. Contrast injection of the drain 4 weeks later demonstrated resolution of the abscess cavity but communication with the biliary tree. The drain was removed and the tract embolized with Gel-foam to prevent complications of biliary-cutaneous fistula. She remains well without evidence of abscess or disease recurrence. Thus, RFA can be used in treatment of limited isolated hepatic metastases from previously treated pancreatic adenocarcinoma. However, the incidence of hepatic abscess is increased due to bilioenteric anastomosis; extended antibiotic prophylaxis should be considered.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
8/31. Extended right hepatectomy with total caudate lobe resection and biliary tree resection for a large colorectal liver metastasis involving both the right and left hepatic lobes and the umbilical fissure: a case report.Very large right-sided liver tumors may grow up to the base of the umbilical fissure and involve the left hepatic duct and can occasionally reach the bile duct confluence. This kind of involvement has often been considered a contraindication to resection. We report a patient who presented with a large hepatic metastasis from colorectal cancer that reached the umbilical fissure and involved the left hepatic duct just above the bile duct confluence. An extended right hepatectomy including complete resection of caudate lobe was performed. We resected the left and common hepatic ducts, as well as both the entire hepatic and the proximal third of common bile duct. A long jejunal limb Roux-en-Y (45 cm) single-layer left intrahepatic hepaticojejunostomy was constructed. She is still well 14 months postoperatively. To the best of our knowledge, this is the first report of such a procedure employed for the treatment of a liver metastasis from colorectal cancer. Extended right hepatectomy including complete caudate lobe resection can be feasible even when the majority of the extrahepatic biliary system needs to be resected. Our approach probably offers the only chance to prevent early death from liver failure in these patients.- - - - - - - - - - ranking = 4keywords = tree (Clic here for more details about this article) |
9/31. Biloma following repeated transcatheter arterial embolization and complicated by intrahepatic duct stones: a case report.Biloma is an encapsulated bile collection outside the biliary tree due to a bile leak. It is occasionally found following traumatic liver injury or iatrogenic injury to the biliary tract, induced either during an endoscopic or surgical procedure. It is a rare complication of transcatheter arterial embolization (TAE). Although biloma can be shrunk by appropriate aspiration or drainage in majority of cases, we report a case of intrahepatic biloma following repeated TAE for hepatocellular carcinoma (HCC) and complicated by infection and intrahepatic stones. This particular constellation of problems has not been reported before and the intrahepatic stones need to be removed by percutaneous procedure.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
10/31. Bronchobiliary fistula detected with hepatobiliary scintigraphy.Bile leakage into the thoracic cavity is a rare complication of invasive cancer. A 12-year-old boy was diagnosed with undifferentiated sarcoma of the right lobe of the liver invading the diaphragm. An extended right hepatectomy and total resection of the mass was performed, leaving a patchy tumoral invasion at the anterior diaphragmatic surface. Surgery was followed with a combined chemotherapy regimen. In the sixth postoperative month, he was readmitted with bilious expectoration. Tc-99m mebrofenin hepatobiliary scintigraphy revealed radiotracer accumulation in the right hemithorax. Bile leakage into the right thoracic cavity was diagnosed based on the hepatobiliary scintigraphic findings. For this patient; hepatobiliary scintigraphy, which is routinely used to visualize the liver and biliary tree, provided a noninvasive mean for the precise diagnosis of a bronchobiliary fistula. The fistula was then confirmed and corrected with surgery. The patient recovered uneventfully.- - - - - - - - - - ranking = 1keywords = tree (Clic here for more details about this article) |
