[Congenital cystic dilatation of the bile ducts: case report and review of the literature]. / Le dilatazioni cistiche congenite delle vie biliari: case report e revisione della letteratura.

Congenital cysts of the biliary tract are rare anomalies generally observed in pediatric age, exceptionally in adults. The different extension and the morphology of cystic lesions make possible a classification in subtype. This disease, of Len asymptomatic, is characterized by high incidence of complications such as pancreatitis, cholangitis, and cancer. For these reasons, congenital cystic dilatation of bile duct should be radically treated by complete resection of the dilated extraepatic biliary tract. A review of the International Literature and a rare case of congenite dilatation of the intra and extraepatic biliary ducts in a female 54 years old, treated by choledochal resection with hepatico-jejunostomy on Roux en Y segment, are presented.

[Comparison of traditional methods and digital technics in the study of the biliary and pancreatic systems using endoscopic retrograde cholangiopancreatography (ERCP)]. / Confronto tra metodica tradizionale e tecnica digitale nello studio delle vie biliari e pancreatiche mediante colangiopancreatografia retrograda per via endoscopica (ERCP).

ERCP holds a key role in the diagnosis of pancreatic-biliary disease. In this technical paper the authors report their experience with computed radiography (CR) in ERCP diagnostic imaging. A stimulable phosphor system was employed (Toshiba TCR-201). Fifteen pancreatic-biliary patients were studied with both conventional and CR techniques. With the same diagnostic output and radiological system, CR was superior to conventional technique in: dramatic exposure-time reduction, image post-processing (exposure error amendment, contrast change, spatial filtering, zooming, gray-scale inversion, etc.), patient exposure reduction, and digital archiving.
