Microbiology in Obstructive BIliary Disease

July 19, 2022 updated by: Dr. med. Hector Eloy Tamez Perez, Hospital Universitario Dr. Jose E. Gonzalez

Clinical-Microbiological Evaluation of the Obstructive Biliary Disease

Patients admitted to hospital due to obstructive biliary disease secondary to benign and malign etiologies, undergoing ERCP, will be selected. Bile sample will be taken in ERCP procedure with sterile technique. Its macroscopic appearance will be assessed and biliary culture will be performed.

Conditions

Detailed Description

The sample of biliary aspirate will be assessed as follows.

  1. Its macroscopic appearance will be analyzed: yellow, black, or purulent.
  2. Biliary culture will be performed; if bacterial growth is observed, its identification will be carried out by means of MALDI-TOF MS mass spectrometry and antibiotic susceptibility tests will be carried out, using the automated VITEK system.

Patients with obstructive biliary disease
Patients admitted to hospital due to obstructive biliary disease secondary to benign and malign etiologies, undergoing ERCP, will be selected. Bile sample will be taken in ERCP procedure with sterile technique. Its macroscopic appearance will be assessed and biliary culture will be performed.

The sample of biliary aspirate will be assessed as follows.

  1. Its macroscopic appearance will be analyzed: yellow, black, or purulent.
  2. Biliary culture will be performed; if bacterial growth is observed, its identification will be carried out by means of MALDI-TOF MS mass spectrometry and antibiotic susceptibility tests will be carried out, using the automated VITEK system.
Other Names:
  • MALDI-TOF MS mass spectrometry for bacteria identification
  • Antibiotic susceptibility for identified bacteria

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Prevalence of bacterial isolation in the obstructive biliary disease measured by percentage calculation
Time Frame: 1 year
Determine the prevalence by percentage measurement of bacterial isolation in bile fluid in the obstructive biliary disease in patients undergoing ERCP.
1 year

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Bacteria in the obstructed bile duct
Time Frame: 1 year
Isolate and identify most common bacteria that colonize and infect the obstructed bile duct by means of biliary culture and MALDI-TOF MS mass spectrometry, respectively
1 year
Antibiotic susceptibility of isolated bacteria in bile fluid
Time Frame: 1 year
Determine antibiotic susceptibility of the isolated bacteria in bile fluid of patients with obstructed bile duct by means of the automated VITEK system
1 year
Bacteria and etiology of obstructive biliary disease
Time Frame: 1 year
Association between isolated bacteria and the etiology of obstructive biliary disease
