Percutaneous biliary drainage : a12-year experience

Abstract EN

To report 12 years (108 patients, 273 procedures) experience and clinical outcome of percutaneous biliary drainage, with and without stent application, in benign and malignant obstruction.

A retrospective study of patients who presented biliary obstruction and who had percutaneous biliary drainage, with or without stent application.

The technical success of external biliary drainage (EBD), dual biliary drainage (DBD) and stent application was 97 %, 91 %, and 98 %.

EBD patients with obstructive jaundice and cholangitis (36) showed good clinical outcome in 67 % and was poor in 33 %.

EBD patients with obstructive jaundice, (39) only showed good clinical outline in 62 %, fair in 31% and poor in 7 %.

The mean potency for soft stents is 32.7 and 7.4 months in benign and malignant strictures.

The mean potency for metallic stents is 26.8 and 4.5 months in benign and malignant strictures.

Adequate laboratory results were not obtained in (33) patients whose general condition improved after (EBD).

The complication rate is 11% for (EBD) and (DBD), 20 % for all stents.

The 30-day mortality for (EBD) and (DBD) is 3 % and none was noted post stent application.

Percutaneous biliary drainage, with or without stent application, is useful in the diagnosis and management of patients with malignant or benign biliary tract obstruction.
