Objective:
To describe the use of percutaneous cholangioscopy in older patients with complex diagnostic and therapeutic bile duct disorders.
Design:
Case series.
Setting:
Tertiary care center.
Patients:
Fourteen patients with a mean age of 74 (SD +/- 9) years (range, 60-91 years) underwent percutaneous cholangioscopy. Eleven of these patients presented with endoscopically irretrievable bile duct stones. These 11 patients represent 4.1% of a group of 342 patients (age > or = 60 years) with a mean age of 76 (SD +/- 9) years who were treated endoscopically because of common bile duct stones between January 1993 and January 1996. Three patients presented with obstructive jaundice resulting from a bile duct stricture. In these three patients, brushing cytology of the strictures had proved to be negative.
Intervention:
After creation and dilatation of a percutaneous transhepatic tract, cholangioscopy was carried out with a flexible cholangioscope. All procedures were performed under mild sedation and analgesia. Stone disintegration was obtained by electrohydraulic lithotripsy, applied through the working channel of the cholangioscope.
Results:
Complete stone disintegration and removal was obtained after one to three cholangioscopic sessions in all 11 patients with stones. A histological diagnosis of malignancy was obtained in the three patients with biliary strictures.
Conclusions:
Percutaneous cholangioscopy is a well tolerated and promising technique in our diagnostic and therapeutic strategy in older patients with complex biliary disorders not responsive to peroral endoscopic diagnosis or treatment.
