Clinical History
Elderly female patient with end-stage infiltrative gastric cancer was previously treated by percutaneous biliary drainage. The patient pulled the catheter one month after placement and was re-admitted. A bilio-cutaneous fistular canal was persistent with bile oozing on the skin surface.
Imaging Findings
A year after initial diagnosis and partial gastrectomy followed by chemotherapy and radiotherapy, CT findings show progression of the tumour mass, infiltrating distal part of the common bile duct, duodenum, pancreatic head and spreading toward the hepatic porta. Additional ultrasound study confirms dilatation of intrahepatic biliary ducts due to common bile duct obstruction by a solid mass.

ERCP stenting was attempted to relieve the patient's symptoms (jaundice) but was aborted because of distal obstruction of the common bile duct.

Finally the patient had permanent percutaneous drainage catheter placed in the common hepatic duct, after which the bilirubin levels returned to normal and the clinical symptoms of jaundice subsided (Fig. 5).
Discussion
The patient had a partial gastrectomy, followed by chemotherapy and radiotherapy.

The patient was admitted to our hospital a year after the initial diagnosis and subsequent oncologic treatment. CT showed further progression of the tumor mass and infiltration of the surrounding structures. In cases of malignant biliary obstruction, the first course of treatment is drainage by endoscopically placed stent (ERCP stenting) [11]. However, in cases of very distal obstruction of the common bile duct, endoscopic access may often be impossible. Internal drainage by percutaneously placed stent is the second option, followed by external drainage as the preferred course of action [10, 5].

ERCP as well as percutaneous internal stenting was attempted but unsuccessful due to hard and rigid obstruction of the common bile duct. Finally, a percutaneous, external biliary drainage was performed which relieved the imminent symptoms caused by jaundice. This was a palliative procedure, but causing a significant improvement in patient's quality of life [1, 4, 8] (Fig. 1, 2).

One month after the original procedure, the patient was readmitted because she accidentally pulled the catheter. The fistular canal remained patent with bile leakage. This time we performed a twofold procedure, first inserting a new 8F catheter to ensure adequate biliary drainage. A percutaneous biliography was performed via this catheter, which also proved that the patent fistular canal was connected to the main hepatic duct. A second catheter was inserted in this canal and it was embolised with a mixture of acrylate and lipiodol (Fig. 3, 4). The embolisation procedure gave good results and the fistular canal was closed [11, 2].

While our approach and choice of materials are non-standard, this was an unusual case with a complicated, terminal patient who was admitted from an outside institution just for this procedure (no follow-up).

Percutaneous liver biliary drainage (PTBD) is a complicated procedure in interventional radiology and it is the best palliative treatment for patients with malignant obstructive jaundice where ERCP stenting is not possible [3, 7]. Acute periprocedural complications of PTBD include haemorrhage, septicaemia, AV fistula formation and subphrenic abscess formation. They are seen in 5 - 10% of cases, while minor periprocedural complications include fever and haemobilia (20 - 30% of cases). Chronic complications are experienced in almost every patient and include catheter obstruction, dislodgement, peri-catheter bile leakage and others [9, 6]. Catheters should be flushed with saline at least once a day and, exchanged every 3 - 4 months.
