ABSTRACT
Background: Antibiotic policy and appropriate antibiotic prophylaxis cannot be designed unless data is available about bacteria colonizing the bile associated with gall bladder disease. Authors aim was to assess the clinical profile and pattern of bacterial isolates from bile aspirates of cholecystectomy patients seeking care at a tertiary care teaching hospital.Methods: Patients who underwent cholecystectomy for various hepatobiliary ailments during year 2017-18 formed the study population. Bile aspirates were collected during cholecystectomy and sent to the microbiology laboratory. Ultrasonography, computed tomography and MRCP were done to confirm the gall bladder pathology before surgery.Results: Out of total eighty-six patients, bacterial growth was observed in 28 (32.56%) subjects. As per division of bile samples, maximum number of study participants (39.29%) having bactibilia were seen in Group II. Group with second highest number of patients showing bactibilia was Group III with 9 subjects (32.14%). Eight subjects (28.57%) exhibited bacterial growth in bile aspirates in Group I subjects. Three patients (10.71%) showed bile infected with multiple bacteria i.e. polymicrobial infection. The gram-negative preponderance was seen in all the three groups with Escherichia coli being most common in group I and II. Pseudomonas aeruginosa was isolated in majority of the patients in group II and III.Conclusions: It is advised that all patients undergoing cholecystectomy must have their bile aspirated during cholecystectomy and sent for microbiological examination and culture. It will help in choosing appropriate antibiotic to prevent infection.
ABSTRACT
Background: A good and an effective empirical treatment of SBP is not possible unless bacteriological spectrum and their antibiogram is clear. This becomes more important in country like India due to high antibiotic resistance. Authors aim was to assess the prevalence of SBP, clinical and microbiological profile of its variants, in patients with cirrhosis seeking care at a tertiary care teaching hospital.Methods: Patients of liver cirrhosis with ascites seeking care at study subject during January- December 2018 formed the study population. Diagnosis was based on clinical examination, biochemical investigation and ultrasonography. Diagnostic abdominal paracentesis was performed on subjects within 24 hours of admission. Ascitic fluid was aspirated. It was sent for microbiological examination.Results: Prevalence of SBP was 16.12%. Out of total ten subjects with Spontaneous Bacterial Peritonitis (SBP), six subjects were of Culture Negative Neutrocytic Ascites (CNNA). Thus most common (60%), variant of Spontaneous Bacterial Peritonitis (SBP) was Culture Negative Neutrocytic Ascites (CNNA). Prevalence of Mono-microbial Non-neutrocytic Bacterascites (MNBA) and Classic-Spontaneous Bacterial Peritonitis (C-SBP) was 20%. Two subjects found positive for MNBA, Staphylococcus aureus and Acinitobacter spp. was detected in each patient. Klebseila pneumonia, Escherichia coli and Coagulase negative Staphylococcus were found in ascitic fluid culture of C-SBP. In clinical variants of SBP, 80% subject’s complaint about abdominal pain. Hepatic-encephalopathy and fever was seen in 7(70%) patients. Rebound tenderness was seen among 60%.Conclusions: Diagnostic paracentesis should be advised to all cirrhotic patients with ascites. Ascitic fluid analysis should be sent for better selection of antibiotics thus better outcome of cirrhotic patients.
