摘　　要：BACKGROUND Achromobacter xylosoxidans is a Gram-negative opportunistic aerobe,usually causing nosocomial infections in immunocompromised patients with manifestations including bacteremia,pneumonia,and catheter-related infections.However,A.xylosoxidans have not yet been reported to cause biliary system infections.CASE SUMMARY A 72-year-old woman presented to the outpatient department of our hospital with a chief complaint of jaundice.Computed tomography of her abdomen revealed the presence of a mass of approximately 2.4 cm in the hilar portion of the common hepatic duct,consistent with hilar cholangiocarcinoma.We performed endoscopic retrograde cholangiopancreatography(ERCP)to decompress the obstructed left and right intrahepatic ducts(IHDs)and placed 10 cm and 11 cm biliary stents in the left and right IHDs,respectively.However,the day after the procedure,the patient developed post-ERCP cholangitis as the length of the right IHD stent was insufficient for proper bile drainage.The blood culture of the patient tested positive for A.xylosoxidans.Management measures included the replacement of the right IHD stent(11 cm)with a longer one(12 cm)and administering culturedirected antibiotic therapy,solving the cholangitis-related complications.After the cholangitis had resolved,the patient underwent surgery for hilar cholangiocarcinoma and survived for 912 d without recurrence.CONCLUSION A.xylosoxidans-induced biliary system infections are extremely rare.Clinical awareness of physicians and endoscopists is required as this rare pathogen might cause infection after endoscopic procedures.
