Evaluation of Blood Stream and Biliary Tract Infections Related to Percutaneous Transhepatic Cholangiography and...

Percutaneous transhepatic cholangiography (PTC) is an invasive procedure used in patients with obstructive jaundice in the progress of some malignancies, and its most common complication is infection. We aimed to evaluate the patients who underwent PTC regarding their cultures, prophylaxis, and antibiotics used for treatment.

In this cross-sectional study, patients who underwent PTC and were followed up in a medical oncology outpatient clinic between 2010-2017 were evaluated retrospectively. Patients' data were obtained from the hospital record system (FONET), epicrisis forms, and patient progress files.

A total of 93 patients were included in the study. Prophylaxis was given in 50% of the cases. Complications developed in 68% of the cases after the intervention, and the infectious disease clinic consulted all. Blood cultures were obtained from 89% of the febrile patients; however, bile cultures were obtained only from 29%. The rate of resistant Gram-negative enteric bacteria in growing microorganisms was 52% (n=13). It was determined that 65% of the initiated empirical treatments were appropriate for the growth of microorganisms.

The growth rate was significantly higher in blood cultures than in bile cultures. The lower growth rate in bile culture was attributed to the low number of bile cultures. There was no significant difference regarding the growth rate and drug resistance of the microorganisms. Therefore, we think giving antibiotics as treatment rather than prophylaxis is more appropriate. Taking cultures will ensure that patients receive appropriate antibiotic therapy for the causative agent.
