Here, we report a case of cholangiocellular carcinoma that was successfully treated with chemotherapy using a selective intra-arterial infusion technique. A 65-year-old man presented to our hospital to obtain a second opinion regarding his disease. The patient was diagnosed with cholangiocellular carcinoma. The giant tumor was located in the porta hepatis. Some small nodules that were considered to be metastatic lesions were also observed in the surroundingarea. The tumor was judged by the primary physician to be too large for surgical treatment...

The porta hepatis and hepatoduodenal ligament (HDL) are important anatomical pathways of extension of disease to and from the liver. The imaging of this area is difficult. The role of endoscopic ultrasound (EUS) as an imaging modality for hepatoduodenal ligament has not been established so far. All images in the present study have been generated from a detailed review of real time recordings using the curved linear scanning echoendoscope EG -3830 UT (Pentax Corporation, Tokyo, Japan), coupled with a Hitachi avius and Hitach 7500 processor (Hitachi Aloka Medical, Tokyo Japan)...

Arterial conduits are necessary in nearly 5% of all liver transplants and are usually constructed utilizing segments of donor iliac artery. However, available segments of donor iliac artery may not be lengthy enough or may not possess enough quality to enable its inclusion in the conduit. Although there are few reports of arterial conduits constructed solely utilizing prosthetic material, no previous reports of conduits composed of a segment of donor iliac artery and prosthetic material (mixed biologic and synthetic arterial conduits) were found in the medial literature to date...

BACKGROUND: Peliosis hepatis is an uncommon vascular condition characterized by multiple, randomly distributed, blood-filled, and cyst-like cavities throughout the liver. The unique clinical nature consisting of an asymptomatic, benign, and incidental finding sometimes conceals itself even until autopsy. However, the exact pathomechanism remains as yet unproven. METHOD: We encountered the patient with multiple hypervascular masses in the whole liver and investigated the clinicopathological features underlying this condition...

A 66-year-old man, with an abnormal porta hepatis, consistent with tumor or inflammation, developed massive bleeding from one of numerous hepatic artery aneurysms, and coil embolization achieved control of bleeding. He died of subsequent multisystem organ failure, and the most likely diagnosis was either polyarteritis nodosa or segmental arterial mediolysis. Although the dual hepatic blood supply allows a degree of arterial embolization, this case demonstrates the risks associated with large territory hepatic arterial embolization in the presence of hemodynamic instability...

Peliosis hepatis (PH) is a condition involving benign tumors pathologically characterized by multiple blood-filled cavities, mostly affecting the liver and spleen. Androgenic-steroids are widely used in patients with bone marrow failure syndromes (e.g.: aplastic anemia) and these patients are at increased risk of developing PH. Although patients with PH are generally asymptomatic, PH can progress to liver failure and even fatal spontaneous intraabdominal hemorrhage. Therefore, early diagnosis is critical in order to prevent life-threatening complications of PH...

BACKGROUND: Schwannomas are mesenchymal neoplasms that arise from Schwann cells with low malignant potential. Schwannomas originating from the porta hepatis or intra-abdominal organs are extremely rare. To our knowledge, multiple schwannomas synchronously occurring in the porta hepatis, liver, and gallbladder have not been reported so far and we first report one in the present case. CASE SUMMARY: A 31-year-old female was referred to our hospital because of repeated abdomen discomfort, slight abdominal distension, and occasional abdominal pain for seven years...

Pancreaticoduodenectomy (Whipple's procedure) remains the only definitive treatment option for tumors of the periampullary region. The most common and life-threatening complications following the procedure are pancreatic anastomotic leakage and subsequent fistula formation. When these complications occur, treatment strategy depends on the severity of anastomotic leakage, with patients with severe leakages requiring reoperation. The optimal surgical method used for reoperation is selected from among different options such as wide drainage, definitive demolition of the pancreaticojejunal anastomosis and performing a new one, or completion pancreatectomy...

Gregory M Anstead
In 1915, a British medical officer on the Western Front reported on a soldier with relapsing fever, headache, dizziness, lumbago, and shin pain. Within months, additional cases were described, mostly in frontline troops, and the new disease was called trench fever. More than 1 million troops were infected with trench fever during World War 1, with each affected soldier unfit for duty for more than 60 days. Diagnosis was challenging, because there were no pathognomonic signs and symptoms and the causative organism could not be cultured...

Anabolic androgenic steroids (AAS) have been abused for decades by both professional and amateur athletes in order to improve physical performance or muscle mass. AAS abuse can cause adverse effects, among which are hepatotoxic effects. These effects include cholestatic icterus and possibly peliosis hepatis and hepatocellular carcinoma or adenoma. In particular, 17α-alkylated AAS appear to be hepatotoxic, whereas nonalkylated AAS appear not to be. The 17α-alkyl substitution retards hepatic metabolism of the AAS rendering it orally bioavailable...

Heterotopic pancreas (HP) is often an incidental finding during operative or endoscopic procedures and described in case reports and small series in the literature. Large clinicopathological studies with a systematic analysis remain lacking. Herein, we identified 184 (0.18%; 184/99 544) consecutive histology-proven HP cases of 89 770 surgical resections and 9774 upper endoscopic biopsies carried out at a single medical center in China. Each case was diagnosed by unequivocal identification of pancreatic acini at a location outside the pancreas...

The present study aimed to investigate the effects of melatonin (MT) on liver function and lipid peroxidation following hepatic ischemia-reperfusion injury (IRI). A total of 66 male Sprague-Dawley rats were randomly assigned into three groups: Normal control (N) group, ischemia-reperfusion (IR) group and the MT-treated group. A hepatic IRI model was developed by blocking the first porta hepatis, and subsequently restoring hepatic blood inflow after 35 min. Following reperfusion, changes in the levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), lactate dehydrogenase (LDH), malondialdehyde (MDA), superoxide dismutase (SOD) and glutathione (GSH) were detected by a chemical method at various time points...

OBJECTIVE: The majority of ovarian cancer patients are initially diagnosed at an advanced-stage [1]. Upper abdominal bulky metastasis cephalad to the greater omentum reported to be present in 42% of patients [2]. Many complex surgical procedures such as splenectomy, pancreatectomy, mobilization and partial resection of liver, porta hepatis dissection, diaphragmatic peritonectomy and resection are frequently performed to achieve complete resection of metastatic disease [3]. Our aim in this surgical film is to show the resection of a left sided diaphragmatic implant located beneath the heart, with dissection from the pericardium after entrance to the pericardial cavity...
