Long-term results (7 to 10 years) of endoscopic papillotomy for choledocholithiasis. Multivariate analysis of prognostic factors for the recurrence o…
1998
Abstract Background: The long-term outcome after endoscopic papillotomy is poorly defined. The aim of this study was to determine the long-term results of this method in the treatment of common duct calculi and to determine which prognostic factors are associated with the relapse of biliary symptoms. Methods: Between 1985 and 1988, 223 consecutive (149 women, mean age 67.9 years) patients underwent endoscopic papillotomy for duct stones; 127 had already undergone cholecystectomy or underwent this operation during the same hospitalization. Follow-up data were obtained retrospectively from the patients and patients' relatives and general practitioners. Results: The procedure was successful in…
Anti-actin antibodies in celiac disease: correlation with intestinal mucosa damage and comparison of ELISA with the immunofluorescence assay.
2005
The presence in the sera of celiac disease (CD) patients of anti-actin autoantibodies (AAAs) has been suggested as a marker of severe intestinal villus atrophy (1). AAAs have been detected with an immunofluorescence (IF) technique and seem to contribute to villus cytoskeleton damage and to the pathogenesis of intestinal damage in CD (2). The aims of the present study were to evaluate the relationship between the presence of serum IgA AAAs and severity of intestinal mucosa damage in CD patients and to compare the IF assay with a new ELISA for IgA AAA determination. We enrolled 150 individuals in the study. IgA AAAs were assayed in 58 consecutive CD patients diagnosed between January and Dece…
CEUS in the differential diagnosis between biliary sludge, benign lesions and malignant lesions
2017
Abstract PURPOSE: Conventional grayscale ultrasound (US) is accurate in the diagnosis of gallbladder disease (GD), but in some cases, it is not decisive. Contrast-enhanced ultrasound (CEUS) improves the diagnostic accuracy of US. The primary objective of this study is to assess the reliability of CEUS in the diagnosis of sludge; the secondary objective is to assess the ability of CEUS to diagnose cancer. METHODS: We retrospectively reviewed the US of 4137 patients positive for GD. In 43/4137 (1.04%), the use of could not discriminate between sludge and neoplasms. Then, we evaluated CEUS in only 39 of these patients, and in 4/43 (9%) cases it was not performable. After CEUS, the absence of e…
Impact of Gallbladder Status on the Outcome in Patients with Retained Bile Duct Stones Treated with Extracorporeal Shockwave Lithotripsy
2002
BACKGROUND AND STUDY AIMS The use of endoscopic therapy in combination with lithotripsy techniques has become increasingly common in patients with complicated common bile duct stones. In many units, although this is controversial, cholecystectomy is then performed, because of possible subsequent cholecystitis and recurrence of choledocholithiasis. The aim of this study was to investigate whether gallbladder status influences the long-term outcome in patients after extracorporeal shockwave lithotripsy (ESWL) of common bile duct stones. PATIENTS AND METHODS Recruited for the study were 120 patients with an average age of 68 years (range 28 - 86). They were selected from 137 consecutive patien…
Biliary sludge and gallstones in pregnancy: Incidence, risk factors, and natural history
1993
To evaluate the incidence and symptoms of and risk factors for biliary sludge and gallstones during pregnancy and to assess the natural history of these conditions in the first year after delivery.Cohort study.A total of 272 pregnant women recruited in the first trimester.Biliary sludge and gallstones were diagnosed using ultrasonography, both during pregnancy and after delivery. Predictors of the presence or disappearance of sludge and stones were examined.Overall, from the first trimester of pregnancy until the immediate postpartum period, 67 women were newly diagnosed with biliary sludge, and 6 women were newly diagnosed with gallstones. The respective incidence rates were 31% (95% Cl, 2…
Hepatic Hilar and Sectorial Vascular and Biliary Anatomy in Right Graft Adult Live Liver Donor Transplantation
2008
Abstract Introduction The aim of this study was to analyze vascular and biliary variants at the hilar and sectorial level in right graft adult living donor liver transplantation. Methods From January 2003 to June 2007, 139 consecutive live liver donors underwent three-dimensional computed tomography (3-D CT) reconstructions and virtual 3-D liver partitioning. We evaluated the portal (PV), arterial (HA), and biliary (BD) anatomy. Results The hilar and sectorial biliary/vascular anatomy was predominantly normal (70%–85% and 67%–78%, respectively). BD and HA showed an equal incidence (30%) of hilar anomalies. BD and PV had a nearly identical incidence of sectorial abnormalities (64.7% and 66.2…
Chromosomal aberrations in patients with primary biliary cirrhosis.
1990
Chromosomal aberrations in untreated lymphocyte cultures, bleomycin (BLM)-induced aberrations and sister chromatid exchanges (SCE) in the peripheral blood lymphocytes of 11 patients suffering from primary biliary cirrhosis (PBC) and 14 matched control individuals were analysed. The lymphocytes of the PBC patients had on average a lower mitotic index (2.3) compared with controls (3.5) in the untreated cultures. The mean baseline rate of aberrations of the cultured lymphocytes of the patients was 5.3 aberrations per 100 metaphases (%); this was significantly different (P = 0.0291) from that of the controls with a mean of 2.3%. In lymphocytes of the patients and controls, most of the aberratio…
Immunoblotting as a confirmatory test for antimitochondrial antibodies in primary biliary cirrhosis.
1993
Primary biliary cirrhosis is characterised by the presence of antimitochondrial antibodies which are directed against components of mitochondrial dehydrogenase complexes. The specificity of antimitochondrial antibodies for primary biliary cirrhosis as detected by immunoblotting was investigated. Commercially available preparations of pyruvate and oxo-glutarate dehydrogenases and beef-heart mitochondria were used as source of antigens. Sera from 47 primary biliary cirrhosis patients (46 of whom were antimitochondrial antibody positive by immunofluorescence), 16 non-primary biliary cirrhosis patients (antimitochondrial antibody positive by immunofluorescence), 23 liver-kidney microsomal antib…
Clinical comparison of extracorporeal piezoelectric lithotripsy (EPL) and intracorporeal electrohydraulic lithotripsy (EHL) in difficult bile duct st…
1995
Today, nearly 90% of common bile duct stones are extracted endoscopically. Problems are encountered if there are large stones or a duct stenosis. Extracorporeal piezoelectric lithotripsy (EPL) as well as intracorporeal electrohydraulic lithotripsy (EHL) serve as an alternative to surgical intervention for those few patients in whom endoscopic measures have failed. A total of 35 patients with common bile duct stones in whom conventional endoscopic treatment had failed were selected on the condition that stone visualization through ultrasound was possible and that the papilla was within easy reach of the endoscope. Patients fulfilling the inclusion criteria were randomly treated either by EPL…
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…
