Abstract

PURPOSE
To evaluate the technical feasibility and clinical efficacy of percutaneous transhepatic biliary drainage (PTBD) through the normal duct in patients with post-operative bile leakage.
MATERIALS AND METHODS
From January 1998 to December 2003, fourteen patients (male: 12, female: 2, mean age: 56) with biliary leak after laparoscopic cholecystectomy (n=5), T-tube removal (n=5), choledochojejunostomy due to small bowel perforation (n=1), right lobectomy (n=1), laparoscopic adrenalectomy (n=1), and subtotal gastrectomy (n=1) were treated by means of PTBD; this was performed with the two-step approach. The central bile duct was cannulated using a 21-G Chiba needle to map the intrahepatic biliary tree. An 8.5-F drainage catheter tip was positioned at the CBD after puncturing peripheral bile duct with an additional Chiba needle. We evaluated the technical feasibility, the procedure-related complications, clinical efficacy and the duration of catheter placement.
RESULTS
PTBD of the normal duct with the two-step approach was successful in all but two cases. In these two cases, the two-step approach was failed due to the rapid disappearance of the targeted peripheral duct, and this was the result caused by biloportal fistula. PTBD was performed through the central bile duct in one patient, and through the remnant cystic duct in one patient. There were no procedure-related complications except for mild abdominal pain in seven patients. Bile leakage was demonstrated on cholangiogram in 10 of 14 patients; this occurred at the T-tube exit site (n=4), cystic duct stump (n=2), choledochojejunostomy site (n=1), resection margin of liver (n=1), caudate lobe (n=1), and GB bed (n=1). In 13 patients, the biliary leak stopped after drainage (mean duration: 32.1 days). In one patient, surgical management was performed one day after PTBD due to the excessive amount of bile leakage.
CONCLUSION
PTBD is a technically feasible and clinically efficacious treatment for post-operative bile leakage, and it can replace the more invasive surgical or endoscopic management procedures.
