    Abstract:
    INTRODUCTION: Percutaneous stenting is established in the palliation of malignant biliary obstruction. We examined the indications, success rate, complications, and long-term postoperative course of patients undergoing this procedure. METHODS: All patients undergoing percutaneous transhepatic cholangiography (PTC) and metal stenting over a 12-month period in a tertiary referral center were studied. Data regarding diagnosis, number and type of procedures, complications, and survival were collected from multidisciplinary case notes and general practitioner records. RESULTS: There were 21 patients of median age 70 (mean, 71; range, 54-93), 56.5% (11) had pancreatic cancer and 33% (7) cholangiocarcinoma. The mean number of PTC procedures was 2.43 and mean length of stay in hospital 20.66 days (range, 3-99). Serum bilirubin fell post drainage from 397 to 226 (μmol/L; p < 0.001) on discharge, however, in 19% (4) there was no significant reduction. Complications included cholangitis (19%) and acute pancreatitis (10%). Mortality was high and 9 patients (43%) died within 30 days, of whom 2 died in the hospital (1 from ascending cholangitis and another from pneumonia). The median time between discharge and death was 25 days (mean, 59.1 days) and no patient was alive after 193 days. CONCLUSIONS: The prognosis following PTC stenting of malignant biliary obstruction is extremely poor despite adequate drainage. The procedure can lead to significant morbidity and a lengthy hospital stay. Patient selection is therefore of paramount importance and an expedient treatment protocol and early return home recommended.
