Attenuation characteristics of portal vein thrombi on nonenhanced computed tomographic (CT) scans were assessed in 122 patients with proved portal vein thrombosis. Portal vein thrombi of high attenuation were found in four patients with hepatocellular carcinoma. From pathologic and radiologic studies, it was concluded that the high attenuation was caused by blood clots of recent onset formed at the tip of tumor thrombus. Differentiation from choledocholithiasis, hematobilia, and calcification of thrombi could be easily made by means of ultrasonography (US). Although plain CT is usually considered noncontributory in the diagnosis of venous thrombosis, it enabled the differentiation of recent thrombus in these four patients. Tumor thrombus in the major branches or main trunk of the portal vein is indicative of poor prognosis. When hepatic mass and high-attenuation portal vein thrombi are demonstrated with plain CT and substantiated by US, enhanced CT and angiography may be unnecessary for treatment of patients with advanced hepatocellular carcinoma.

We describe the features of 24 cases of hepatocellular carcinoma (HCC) with prominent intrabile duct tumor growth seen among 238 autopsy and 21 surgical cases of HCC. Progressive obstructive jaundice occurred during the course of most cases and was the presenting sign in nine. A fluctuating rise and fall of the total bilirubin was seen in two cases. The average survival time of the cases was significantly shorter than that of HCC patients without intrabile duct tumor growth (Mann-Whitney's U-test, one-tailed, P less than 0.05). The average survival time after the development of severe jaundice (total bilirubin over 10 mg/dl) was only 16 days. Intrabile duct tumor casts were located in the hepatic and/or the common bile ducts in 19 cases (79%) and in five cases were seen in the peripheral (medium to small-sized) bile ducts. Hemobilia developed in five cases (21%) and was regarded as the immediate cause of death in one. Grossly all the cases presented infiltrative or mixed (infiltrative and nodular) growth pattern. Intrabile duct tumor growth and associated marked obstructive jaundice may frequently herald the terminal phase of HCC in certain patients. In our series, approximately 40% of patients with HCC and significant jaundice had gross evidence of extensive intraductal tumor growth. In the absence of intraductal tumor growth, jaundice in HCC usually was seen in a setting of progressive terminal hepatic failure.

In this report, we present four cases of hemobilia. Hemobilia occurs when conditions produce an abnormal communication between blood vessels and bile ducts. Although iatrogenic procedures as causes of hemobilia have been reported with increasing frequency, non-iatrogenic etiologies are still quite rare. We, therefore, report 4 cases of hemobilia secondary to different etiologies found in our institution from 1996 to 1998, that are non-iatrogenic. The first patient was a case of congenital aneurysm, the second pseudoaneurysm from trauma, the third cholangiocarcinoma and the fourth hepatocellular carcinoma. The classical triad consists of melena, jaundice and abdominal pain. Direct observation of blood flowing from the Ampulla of Vater by endoscopy was the initial diagnostic procedure in all four cases. Diagnosis was confirmed by ultrasonography, computerized tomography, angiography or surgery. Transcatheter selective embolization as a noninvasive treatment for hepatic aneurysm/pseudoaneurysm is emphasized.

Hemobilia is a rare manifestation of hepatic malignancies. The current treatment of choice for hemobilia is transcatheter hepatic arterial embolization. However, there have been only two published reports that describe the use of hepatic arterial embolization for hemobilia caused by hepatic neoplasms. In addition, this procedure is occasionally unsuccessful in the treatment of hemobilia. A case in which hemobilia caused by hepatocellular carcinoma was successfully treated with percutaneous radiofrequency tumor ablation after several failed hepatic arterial embolizations is described in this report.

Hemobilia is an rare cause of acute pancreatitis. The most frequent causes are iatrogenic trauma (percutaneous liver biopsy) and hepatic artery aneurysm. To our knowledge, this is the second published case of acute pancreatitis related to hemobilia secondary to hepatocarcinoma complicated cirrhosis in a patient treated with anticoagulants for a mechanical valvular aortic prosthesis. The clinical picture included acute epigastric pain, fever and jaundice. Increased amylase and lipase serum activities, and abdominal CT data confirmed the diagnosis of acute pancreatitis. Gallstone induced acute pancreatitis was suspected and thus, a cholecystectomy was performed. No bile duct stones were found but a clot was extracted from the extrahepatic bile duct during surgery. Arterial embolization was then performed and repeated 1 and 3 months later for recurrence. The patient was asymptomatic eight months later. Hepatic arterial embolization is an effective haemostatic treatment for hemobilia, even though, in this case treatment had to be repeated because of an anticoagulant therapy.

A 65-year-old Japanese man underwent radiofrequency ablation (RFA) therapy of a hepatocellular carcinoma. Hemobilia from the intrahepatic bile ducts adjacent to the tumor developed on the fifth day after the RFA therapy. Ultrasonograms and computed tomograms showed swelling of the gallbladder, which was filled with a clot, suggesting the diagnosis of hemocholecyst. The hemobilia resolved with conservative therapy, but a cholecystectomy was performed to manage postprandial abdominal pain. The resected gallbladder was filled with a clot, but injury or ulceration of the gallbladder was absent, suggesting that the hemocholecyst developed secondary to the hemobilia. Secondary hemocholecyst is a rare complication of RFA therapy. The number of cases of secondary hemocholecyst is likely to increase as hepatocentestic therapy becomes more common. Cholecystectomy is indicated for hemocholecyst because spontaneous liquefication and drainage of a clot in the gallbladder usually does not occur.

We report a case of hemobilia developing after RFA for hepatocellular carcinoma. A 75-year-old woman with hepatitis C was diagnosed as hepatocellular carcinoma (d=15 mm) located in subsegment 7. Laboratory data on admission are AFP 37.3 ng/mL, PIVKA-II 20 mAU/mL, GOT/GPT 84/52 IU/L, T-Bil 1.1 mg/dL, Alb 3.8 g/dL, Plt 8.9x104/microL, and PT 11.8 seconds (INR 1.28) "Child classification A". Under general anesthesia, percutaneous RFA (Cool-tip radionics 10 minutes) was performed. Tumor appeared to be well treated, but on day 5 after the procedure, the patient had sudden upper abdominal pain, followed by the elevation of total bilirubin conc. (3.3 mg/dL) and decrease of Hb. Abdominal ultrasonography showed a debris-like shadow in the gall bladder. Hemobilia was confirmed because endoscopic examination revealed blood contaminated bile from the papilla Vater. Since spontaneous thrombolysis is known to occur in the bile, the patient was only followed by MRI. Symptoms were subsided in a week without any treatment. Obstructive jaundice due to hemobilia is a rare complication of RFA, and may be followed without any treatment.

Radiofrequency ablation (RFA) is performed as an alternative to surgical resection for primary or secondary liver malignancies. Although RFA can be performed safely in most patients, early and late complications related to mechanical or thermal damage occur in 8-9.5% cases. Hemocholecyst, which refers to hemorrhage of the gallbladder, has been reported with primary gallbladder disease or as a secondary event associated with hemobilia. Hemobilia, defined as hemorrhage in the biliary tract and most commonly associated with accidental or iatrogenic trauma, is a rare complication of RFA. Here we report a case of hemocholecyst associated with hemobilia after RFA for hepatocellular carcinoma that was successfully managed by laparoscopic cholecystectomy.

The prognosis of patients with obstructive jaundice caused by hepatocellular carcinoma (HCC) is dismal, because effective biliary drainage is difficult due to frequent malfunction of the drainage tube caused by hemobilia and/or tumor emboli. Photodynamic therapy (PDT) improves biliary patency and prolongs survival in hilar cholangiocarcinoma. The aim of this study was to assess the safety and efficacy of PDT in unresectable HCC with bile duct invasion. Between January 2009 and September 2010, eleven patients with bile duct invasion of unresectable HCC were enrolled at Samsung Medical Center. PDT was performed with 180 J cm(-1) light activation 48 hours after administration of the photosensitizer at a dose of 2 mg kg(-1) body weight. Biliary drainages were performed in all patients. The safety and efficacy of PDT were prospectively evaluated. Eleven patients had successful PDT and biliary drainage. Jaundice improved in seven out of ten patients who had jaundice before PDT. Hemobilia, which had developed in six cases, was controlled by PDT. There were no complications from the photosensitizer. There was no 30-day mortality, and the mean survival was 140.5 days. PDT controlled hemobilia associated with bile duct invasion of HCC and could be an effective treatment option in these patients.

Massive bleeding hemobilia occurs rarely in patients with hepatocellular carcinoma (HCC) without any invasive procedure. Upper gastrointestinal bleeding in patient with cirrhosis and abdominal pain with progressive jaundice in patient with HCC were usually thought as variceal bleeding and HCC progression respectively. We experienced recently massive bleeding hemobilia in patient with HCC who was a 73-year old man and showed sudden abdominal pain, jaundice and hematochezia. He had alcoholic cirrhosis and history of variceal bleeding. One year ago, he was diagnosed as HCC and treated with transarterial chemoembolization periodically. Sudden right upper abdominal pain occurred then subsided with onset of hemotochezia. Computed tomography showed bile duct thrombosis spreading in the intrahepatic and extrahepatic ducts, while an ampulla of vater bleeding was observed during duodenoscopy. Hemobilia could be one of the causes of massive bleeding in patients with cirrhosis and HCC especially when they had sudden abdominal pain and abrupt elevation of bilirubin.
