The present review describes the various indications of biliary stent placement in patients with biliary malignancies. It deals in depth with biliary accesses and their effectiveness, as well as with the use of different stents according to lesion type and expected patient survival. For liver hilum lesions, which are somewhat more complex, the usefulness of and need for unilateral or bilateral ...

Transcatheter embolization is considered to be less effective for early-stage hepatocellular carcinomas (HCCs) without a hypervascular arterial supply. In the present case report, a 65-year-old male with hepatitis type C and non-hypervascular HCC located in the hepatic hilum was successfully treated by bland transarterial embolization (TAE). After the temporary protective embolization of normal...

BACKGROUND The negative result of a research does not always indicate failure, and when the data do not permit a proper conclusion, or are contrary to the initial project, should not simply be discarded and archived. AIM To report failure after performing experimental model of liver ischemia and reperfusion normothermic, continuous or intermittent, in small animals aiming at the study of bioc...

Chest X-ray is a usual tool for family physicians; however, unexpected findings in chest X-ray are a frequent challenge. We present a rare case of pulmonary hilar nodule misdiagnosis in a chest X-ray. An 84-year-old woman was sent with a diagnosis of a right pulmonary hilum nodule. She had a history of chronic obstructive pulmonary disease; so in a chest X-ray, her family physician discovered a...

Granulocytic sarcoma (GS) is an extramedullary tumor composed of immature myeloid cells, typically occurring during the course of acute myelogenous leukemia. Non-leukemic GS, that is, GS with no evidence of overt leukemia and no previous history of leukemia, is very rare, and even more unusual is nonleukemic GS of the bile duct. We report a case of nonleukemic GS of the bile duct. The patient w...

INTRODUCTION Increasing evidence suggests that surgical resection may be offered to a subgroup of patients with liver metastasis of gastric adenocarcinoma. The aim of this case report is to illustrate the surgical resection of a single liver metachronous recurrence twelve months after a radical total gastrectomy for cancer. CASE REPORT A 63-year-old male patient with an Eastern Cooperative On...

HYPOTHESIS A reproducible and potentially reversible model of acute liver failure in the pig is feasible based on transient ischemia of the liver. DESIGN To determine the shortest period of liver ischemia sufficient to cause 100% mortality, ischemia of the liver was induced for different lengths of time, starting with 6 hours. If the pig survived, ischemia time was prolonged for 2 hours in th...

OBJECTIVE Ganglioneuromas are rare benign tumors originating from ganglion cells. Ganglioneuromas are detected incidentally because they are asymptomatic. We report a case of laparoscopic excision of a retroperitoneal ganglioneuroma. CASE DESCRIPTION A 49-y-old female was admitted to our medical center with the complaint of abdominal pain. Abdominal ultrasound showed a hypoechoic solid lesion...
