Electromagnetically generated extracorporeal shockwaves for fragmentation of extra-and intrahepatic bile duct stones: indications, success and proble…

1990

Electromagnetically generated extracorporeal shock waves (without waterbath) were applied after intravenous premedication with 10-15 mg diazepam and 100 mg tramadol in the treatment of 33 patients (aged 32 to 91 years) with multiple intrahepatic stones (n = 4) or huge common bile duct stones (n = 29, 18-30 mm in diameter), which could not be removed by conventional endoscopy. Stone disintegration was achieved in 70% of common bile duct stones and in all intrahepatic concrements after 800-7500 discharges, which were applied during one (n = 21), two (n = 6) or three sessions (n = 6). Apart from mild fleabite-like petechiae at the side of shock wave transmission no other side effects were obse…

A Phase II Trial of Fixed-Dose Rate Gemcitabine plus Capecitabine in Metastatic/Advanced Biliary Tract Cancer Patients

2011

<i>Background:</i> This phase II trial was conducted to determine the activity and safety of the combination of fixed-dose rate (FDR) gemcitabine and capecitabine in metastatic biliary tract cancer (BTC) patients. <i>Methods:</i> Patients with unresectable BTC who had pathologically confirmed adenocarcinoma, no prior chemotherapy, Eastern Cooperative Oncology Group (ECOG) performance status ≤1 and measurable disease were enrolled. Treatment consisted of FDR gemcitabine at 800 mg/m<sup>2</sup> on days 1 and 8 every 21 days with capecitabine administered orally b.i.d. in equal doses (650 mg/m<sup>2</sup> b.i.d.) for 14 days (28 doses). <i>…

High risk of bacterobilia in advanced experimental chronic fasciolosis

2006

Fasciolosis is recognized as an important human disease. Wistar rats experimentally infected with Fasciola hepatica were examined using data obtained in the advanced chronic state of the disease (200, 300 and 400 days post-infection, dpi). Pigment stones (PS) and bile specimens were collected. The same procedure was applied in control rats. Liver tests were determined using stored serum samples. Bacteriological bile culture revealed viable bacteria (Escherichia coli, 45% of cases, Enterococcus faecalis, 45% and Klebsiella pneumoniae, 10%). The presence of bacterobilia was associated with liver serum enzymes, including aspartate aminotransferase (AST or SGOT), alanine aminotransferase (ALT o…

Magnetic Resonance Imaging of Liver Transplant

2021

MR imaging increasingly has been adopted for follow-up imaging post-liver transplantation and for diagnosis of its complications. These include vascular and biliary complications as well as post-transplant malignancies. Interpretation of postoperative MR imaging should take into account the surgical technique and expected post-transplant changes. Contrast-enhanced MR imaging has high sensitivity for identification of vascular complications. MR cholangiopancreatography on the other hand is the most accurate noninvasive method for evaluation of biliary complications.

Biliary microbiota in pancreatic cancer

2019

The most common microorganisms were Pseudomonas spp. (P < 0.0001) and E. coli (P < 0.0001), which were negatively correlated to PDAC and positively correlated to cholangiocarcinoma by both univariate and multivariate analysis. Gram-negative bacteria are linked to a tumor-associated inflammatory status

The binding of intravenous and oral biliary contrast agents to human and bovine serum albumin

1978

The binding of two homologous series of oral and intravenous biliary contrast agents to human and bovine serum albumin was investigated using the gel filtration technique. All intravenous compounds are bound to human serum albumin via one high affinity and several low affinity binding sites. Within the concentration range investigated, about 3--5 high affinity binding sites for the oral compounds were found on human serum albumin. In general, the intravenous compounds have a greater affinity for human serum albumin than the oral compounds. No significant differences were found for the binding of the oral compounds to human or bovine serum albumin, while the intravenous compounds have a high…
