Haemobilia: secondary to micro aneurysms of hepatic artery.

Hepatic artery is the fourth most common site of the intraabdominal aneurysm, after infra renal aorta, iliac artery and splenic artery aneurysms. Rupture of the aneurysm may lead to the upper gastrointestinal haemorrhage. Here we report a 5 years old boy, who presented with fever, abdominal distension and unexplained upper GI bleed. Upper GI endoscopy revealed a normal esophagus and stomach with clear evidence of haemobilia with blood oozing from the ampulla. Fluoro- guided angiography followed by embolization of hepatic artery branches with 5 metallic coils was performed in this case by an interventional radiologist.

[Post-traumatic hemobilia. Is selective hepatic artery ligation dangerous?]. / Hémobilie post-traumatique. La ligature sélective de l'artère hépatique est-elle dangereuse?

Selective hepatic artery ligation has traditionally been considered dangerous by some authors in the treatment of traumatic haemobilia. Having observed one case in which this technique was successful in controlling liver haemorrhage, the authors have reviewed the literature. Conditions in which selective hepatic artery ligation can be dangerous are discussed. The safety and effectiveness of this treatment of traumatic haemobilia in normovolemic patients is emphasized.

[Direct and indirect effects of epoietin alpha in an experimental model of thrombosis and bleeding in the rabbit]. / Etude des effets directs et indirects de l'érythropoïétine dans un modèle expérimental de thrombose et de saignement chez le lapin.

OBJECTIVES: To study direct and indirect effects of EPO on haemostasis. STUDY DESIGN: Experimental, randomised. ANIMALS: Forty-eight New Zealand rabbits. METHOD: Animals were anaesthetised, ventilated and monitored continuously for blood pressure, heart rate, body temperature, and carotid blood flow variations and were randomised into four groups: control, EPO bolus 2400 IU kg(-1), fractionated EPO (one injection a week of 600 IU kg(-1) for 4 weeks), homologous red blood cell transfusion to reach the Ht level of the fractionated EPO group. A compression injury and a 75% stenosis of the carotid artery triggered a series of cyclic flow reductions (CFRs). CFRs were observed for a 20 min period in each group. Ear immersion bleeding time (BT) and hepato-splenic bleeding were performed at the end of the experiment. Biology was performed at the end of the thrombosis period: blood cells count, Hte, activated partial thromboplastin time, fibrinogen, arachidonic-induced platelet aggregation, EPO dosages. RESULTS: No significant increase in thrombosis (CFRs) in the two EPO groups and in the transfused group. Increase in Hte in the fractionated EPO group versus control. Group EPO bolus: decrease in BT and hepato-splenic bleeding versus control; decrease in hepato-splenic bleeding versus fractionated EPO group, increase in platelet aggregation velocity versus control. CONCLUSION: EPO did not increase the thrombotic risk in this rabbit model. EPO bolus decreased BT and hepato-splenic bleeding.

Right hepatic arterial pseudoaneurysm with hemobilia following minilaparotomy cholecystectomy: a rare complication.

Hepatic arterial pseudoaneurysm with hemobilia occurs less frequently as a complication of minilaparotomy cholecystectomy than laparoscopic cholecystectomy; however, given its severe nature, it needs to be managed promptly. This report presents a case of right hepatic artery pseudoaneurysm with hemobilia in a 36-year-old woman who underwent minilaparotomy cholecystectomy 5 weeks earlier. Angiography with embolization was carried out as definitive treatment.

Hemobilia complicating a liver abcess.

We present the case of an 11-year-old female, with a history of colicky pain abdomen fever, and episode of massive hematemesis and melena. The child was presented to the medical emergency with features of shock. Coagulation profile of the child was normal. Ultrasonography demonstrated multiple liver abscess. Repeated endoscopies ruled out the possibility of gastric or upper gastrointestinal causes of bleed where in the possibility of hemobilia, was considered. Endoscopic retrograde cholangiography demonstrated the presence of bleeding from the biliary tract. Angiography demonstrated the presence of the communication of the biliary radicles with the hepatic vessels and also aided with therapeutic embolization. Hemobilia is a rare cause of upper gastrointestinal hemorrhage with an increasing incidence because of the widespread use of invasive hepatobiliary procedures and improved recognition. In the majority of cases the cause is iatrogenic and those associated with the liver abscess are scantily reported in the English literature. Persistent bleeding sometimes requires urgent therapeutic intervention, such as angiography or surgery.

Hemobilia--evolution of current diagnosis and treatment.

"Hemobilia," upper gastrointestinal tract bleeding that originates from within the biliary tract, has become widely recognized due to an increased clinical awareness of the disorder and to improvements in diagnostic techniques. In addition, the growing use of percutaneous liver puncture for the diagnosis of and therapy for hepatobiliary diseases and the increased incidence of both blunt and penetrating hepatic trauma have contributed to a rising incidence of hemobilia. We review the history, pathophysiology, and current approaches to the diagnosis and treatment of this disease.

Hemobilia in systemic lupus erythematosus.

Symptoms of acute cholecystitis developed in a 22-year-old woman with active SLE. Abdominal ultrasonography and biliary patency scan showed evidence of acalculous cholecystitis and common bile duct obstruction, respectively. Operation revealed acalculous cholecystitis and hemobilia; a liver biopsy specimen also showed hemobilia. Surgery relieved the patient's symptoms. This case demonstrates a new complication of SLE.

Hemobilia and liver flukes in a patient from Thailand.

A patient from Southeast Asia presented with abdominal pain, fever, jaundice, and upper gastrointestinal bleeding of unknown origin. Opisthorchis viverrini eggs were found in the stool and multiple hepatic filling defects were noted on liver scan and sonogram. Endoscopic retrograde cholangiopancreatography revealed cholelithiasis and crescent-like filling defects in the biliary system. At surgery, the gallbladder was filled with clotted blood and pigmented stones. During T-tube drainage of the common bile duct, small elliptical flukes (4 X 3 mm) identified as O. viverrini were recovered. Despite adequate biliary drainage, the patient continued to have high fevers. On the 53rd postoperative day, a larger fluke (2.8 X 0.8 cm) identified as a Fasciola hepatica migrated down the T-tube. Institution of therapy with bithional resulted in complete clinical resolution within 3 wk. Six years later the patient returned with fever, jaundice, and right upper quadrant pain. Two large pigmented stones were found in the common bile duct and were removed after endoscopic sphincterotomy. The stones had developed even though there was no evidence of recurrent helminthic infection.

Hemobilia por ruptura de aneurisma de la arteria hepática / Hemobilia due to ruptured hepatic artery aneurism

We report two patients with hemobilia caused by hepatic artery aneurism that ruptured to the biliary tract. In the first patient, the diagnosis was made during an exploratory laparotomy. In the second patient, the aneurism was diagnosed with a selective hepatic artery arteriography and embolized during the procedure. The evolution of both patients was satisfactory
