AIDS-related cholangiopancreatographic changes.

The cholangiographic and pancreatographic appearances of the acquired immunodeficiency syndrome (AIDS) associated cholangitis were evaluated in 26 patients. Twenty-four patients were diagnosed by retrograde cholangiography or endoscopic cholangiopancreatography (ERC or ERCP). One patient was diagnosed by T-tube cholangiography and another patient by transhepatic cholangiography. The radiographic findings ranged from intrahepatic ductal abnormalities with or without involvement of the extrahepatic biliary tree (eight patients) to irregularities and strictures involving the ampulla of Vater or the intrapancreatic portion of the common bile duct (CBD) with proximal dilatation (18 patients). Significant strictures involving the juxta-ampullary pancreatic duct were identified in six of 12 patients. Twenty-one of the 26 patients had associated infections which included: Cryptosporidium (CS), Mycobacterium avium intracellulare (MAI), cytomegalovirus (CMV), Microsporidium (MSP), and Isospora (ISP). Three patients were operated upon for acute acalculous cholecystitis. In each instance, organisms were identified in both the bile duct and the inflamed gallbladder.

Endoscopic management of biliary tract stones and stenosis.

The role of endoscopy in managing biliary tract stones and stenosis is surveyed. Rapid advances in endoscopic videoimaging with small diameter maneuverable or large instrument channel endoscopes allows diagnosis and therapy under visual or radiographic control at almost any site in the biliary tree. Techniques for cytology, biopsy, sphincterotomy, mechanical or laser lithotripsy, dilatation with balloon or bougie, large (15 F) or small stent insertion, "polypectomy" or excision with laser or electrosurgery, and brachytherapy provide a therapeutic armamentarium that must be considered as painless, low risk, and cost-effective alternatives to surgical or percutaneous therapy.
