Gallbladder sepsis after stent insertion for bile duct obstruction: management by percutaneous cholecystostomy.

Of 364 patients undergoing insertion of a biliary endoprosthesis in 1989, six (1.6 per cent) developed gallbladder sepsis. Three patients had cholangiocarcinoma, two had carcinoma of the pancreas and one had a benign biliary stricture. Two of the five patients with malignancy had gallbladder stones, and the patient with a benign stricture developed stones after 3 years of stenting. Three patients developed gallbladder sepsis early after endoprosthesis insertion (less than 6 days), while in the other three it occurred late (greater than 6 months). All six patients failed to respond to antibiotics and were successfully managed by percutaneous cholecystostomy; the patient with a benign biliary stricture also had cholecystolithotomy. The gallbladder drainage tubes were removed or became dislodged at intervals varying from 2 weeks to 6 months without complications. Percutaneous cholecystostomy is the treatment of choice for gallbladder sepsis unresponsive to antibiotics in patients with a biliary endoprosthesis in situ.
