BACKGROUND Bowel ultrasonography is increasingly used in the detection and follow-up of patients with Crohn's disease, but a limitation to its further diffusion is the lack of standardisation of ultrasonography parameters. AIMS This study aimed to standardise the most common bowel ultrasonography parameters in order to develop an unequivocal imaging(More)
BACKGROUND In the past few years, serologic markers have been proposed in inflammatory bowel disease. Anti-Saccharomyces cerevisiae antibodies showed high specificity for Crohn's disease. A prognostic role for serology has also been hypothesised. AIMS To evaluate anti-Saccharomyces cerevisiae antibody distribution in an unselected Italian inflammatory(More)
BACKGROUND MRCP and EUS have replaced ERCP in the diagnosis of biliary diseases, but the latter is needed for treatment. This study evaluates a new approach in the management of common bile duct stones, by using an oblique-viewing echoendoscope. METHODS Nineteen patients with acute abdominal pain associated with increased liver tests entered the study.(More)
OBJECTIVE Abdominal bowel ultrasound (US) is widely used in the management of Crohn's disease (CD). The aim of this study was to evaluate the prognostic role of bowel-wall US morphology on the short-term risk of surgery. MATERIAL AND METHODS The 147 CD patients recruited in a case-control study comprised 49 cases operated on within 30 days after US(More)
BACKGROUND Diagnosis of pancreatic masses is often difficult. Endoscopic ultrasound-fine needle aspiration has been proposed as the best single-step strategy. AIMS To prospectively evaluate feasibility, effectiveness and safety of endoscopic ultrasound-fine needle aspiration of pancreatic masses in a consecutive study of unselected patients. METHODS Two(More)
BACKGROUND Severe ulcerative colitis is potentially life threatening even though a policy of intensive medical management and early colectomy in recent years reduced mortality to almost zero. However, colectomy, with or without ileal-anal anastomosis, has its own problems (morbidity, pouchitis, cuffitis) and no reliable prognostic index of surgical outcome(More)
Approximately 15% of patients with ulcerative colitis have a severe attack requiring hospitalization at some time during their illness. This treatment leads to a remission in 60-80% of patients and non-responders may require a total colectomy. Mortality in severe episodes of ulcerative colitis decreased from 31-61% in the 1950s to 5-9% in the 1960s thanks(More)
BACKGROUND Thiopurines are increasingly used in the treatment of inflammatory bowel disease (IBD), being the most common immunosuppressive therapy; however, potentially harmful interactions between thiopurines and other drugs (especially 5-aminosalicylic acid, 5-ASA) were described. AIM To explore potential interactions between thiopurines and concomitant(More)
The use of biological and immunosuppressive therapy in Crohn's disease (CD) changed favorably the course of the disease and is currently suggested in the prevention of clinical recurrence. Symptomatic exacerbation is a feature of the natural course of the disease. Endoscopic recurrence may occur earlier than clinical manifestations and its rate is still(More)
Endoscopic evaluation of mucosal appearance is important for the clinical management of ulcerative colitis patients, as it offers valuable prognostic tools and data useful to change the management and treatment strategies. In the field of severe ulcerative colitis, partial endoscopy and bioptic sampling allows to obtain additional and relevant prognostic(More)
