The purpose of this study was to determine the occurrence and clinical characteristics of PBTIs. A retrospective case series review was conducted from January 2006 to August 2014 at a tertiary referral university hospital in Japan. Patients with a blood or bile culture positive for Streptococcus pneumoniae diagnosed with definite cholangitis or cholecystitis according to Tokyo Guideline 2013 were enrolled in this study. Data on clinical information, treatments, and outcomes were collected. During 104 months, 48 cases of positive blood cultures and 13 cases of positive bile cultures were recorded, and after excluding 43 and 5 of these, respectively, a total of 10 patients were diagnosed with PBTI. Most patients (9/10) had biliary tract problems and biliary devices in place. PBTIs were not rare; conversely, they were a relatively common cause of pneumococcal bacteremia in this center treating a high volume of biliary tract illnesses.}, pages = {415--418}, title = {Pneumococcal biliary tract infections – How rare are they?}, volume = {23}, year = {2017} }
