[Endoscopic cholangiography in biliary tract diseases in HIV+ patients].

Unlabelled: Biliary tract involvement in the course of the infection by HIV was first described in 1983. Since then, various opportunistic infections have been responsible of different biliary lesions, coming to a new entity called "cholangiopathy associated to HIV". Our aim was to determined the use of ERCP in the management of HIV patients with cholestasis.

[Factors associated with high grade dysplasia and cancer in colorectal adenoma].

The aim of this study was to assess the risk factors associated with high grade dysplasia (HGD) and cancer (CA) in colorectal polyps. We studied prospectively all colorectal polyps endoscopically resected from 6/91 to 12/93. Analyzed variables were age, sex and initial symptoms of patients, and number, localization, size and histologic characteristics of polyps.

Endoscopic retrograde cholangiopancreatography: before and after laparoscopic cholecystectomy.

In 39 patients with indication of laparoscopic cholecystectomy (LC), an endoscopic cholangiopancreatography (ERCP) was performed before the procedure whenever intermittent cholestasis, acute pancreatitis or ultrasonografic biliary tract dilatation were detected. No abnormality was found in 24 of them. In 14, bile duct stones were removed by endoscopic sphincterotomy (EST).

[Treatment with extracorporeal shockwave (ESWL) in lithiasis of the common bile duct].

During 2 years (1988-1990) 373 patients were studied by ERCP in order to establish the etiology of cholestasis. Biliary duct stones were found in 190. Thirty-nine were treated surgically and 151 by endoscopic sphincterotomy and different extraction techniques.
