Résumé
Polymerase chain reaction is a method to detect bacterial DNA and is widely used because it delivers results within a few hours with the potential to guide postoperative antibiotic treatment. This study aims to determine if polymerase chain reaction can accurately detect bacteria in the peritoneal fluid compared with conventional culture from patients operated for acute appendicitis. This prospective cohort study included patients above the age of 18 years who underwent laparoscopic surgery for acute appendicitis. Peritoneal samples were collected before the appendectomy procedure for conventional culture and polymerase chain reaction using the BioFire Blood Culture Identification 2 Panel for comparison. During surgery, the surgeon assessed the appendicitis as either complicated or noncomplicated. Samples from 102 patients were eligible for analysis. Twelve samples were polymerase chain reaction positive, and 14 samples were culture positive. The concordance of positive results when comparing these 2 methods was 71.4%. The most commonly found bacteria were Escherichia coli and Bacteroides fragilis. Of the 36 patients with complicated appendicitis, no bacteria were detected by either conventional culture or polymerase chain reaction in 21 (58%) of the patients. In patients with uncomplicated appendicitis, bacteria were demonstrated in 1 out of 66 (2%) patients. This study suggests that polymerase chain reaction can be used to detect bacteria in the peritoneal fluid and has the potential to guide postoperative antibiotic treatment.

BACKGROUND
BACKGROUND
Polymerase chain reaction is a method to detect bacterial DNA and is widely used because it delivers results within a few hours with the potential to guide postoperative antibiotic treatment. This study aims to determine if polymerase chain reaction can accurately detect bacteria in the peritoneal fluid compared with conventional culture from patients operated for acute appendicitis.
METHODS
METHODS
This prospective cohort study included patients above the age of 18 years who underwent laparoscopic surgery for acute appendicitis. Peritoneal samples were collected before the appendectomy procedure for conventional culture and polymerase chain reaction using the BioFire Blood Culture Identification 2 Panel for comparison. During surgery, the surgeon assessed the appendicitis as either complicated or noncomplicated.
RESULTS
RESULTS
Samples from 102 patients were eligible for analysis. Twelve samples were polymerase chain reaction positive, and 14 samples were culture positive. The concordance of positive results when comparing these 2 methods was 71.4%. The most commonly found bacteria were Escherichia coli and Bacteroides fragilis. Of the 36 patients with complicated appendicitis, no bacteria were detected by either conventional culture or polymerase chain reaction in 21 (58%) of the patients. In patients with uncomplicated appendicitis, bacteria were demonstrated in 1 out of 66 (2%) patients.
CONCLUSION
CONCLUSIONS
This study suggests that polymerase chain reaction can be used to detect bacteria in the peritoneal fluid and has the potential to guide postoperative antibiotic treatment.
