Background:
Whether perioperative administration is required in elective laparoscopic cholecystectomy (LC) in patients with low risk of infection remains controversial.
Objective:
To investigate whether perioperative use of prophylactic antibiotics during elective LC can reduce the incidence of postoperative infection using a meta-analysis.
Methods:
Pubmed, Cochrane Library, Embase, and reference lists were searched up to October 26, 2020, for randomized controlled trials (RCTs) of the perioperative use of antibiotics during LC. A systematic review with meta-analysis, meta-regression, and GRADE (Grading of Recommendations Assessment, Development and Evaluation) of the evidence was conducted. The Cochrane (RoB 2.0) tool was used to assess the risk of bias.
Result:
A total of 14 RCTs were ultimately included in the meta-analysis, involving a total of 4360 patients. The incidence of surgical site infections, distant infections, and overall infections was investigated and the relationship with the perioperative use of prophylactic antibiotics during LC analyzed. The results indicated that in low-risk patients undergoing elective LC, prophylactic antibiotics reduce the incidence of surgical site infections (RR 0.66; 95% CI 0.45-0.98), with a moderate GRADE of evidence, distant infections (RR 0.34; 95% CI 0.16-0.73), with a low GRADE of evidence and overall infections (RR 0.57; 95% CI 0.40-0.80), with a moderate GRADE of evidence.
Conclusions:
The present meta-analysis demonstrates that the perioperative use of antibiotics in LC is effective in low-risk patients, possibly reducing the incidence of surgical site infections, distant infections, and overall infections. However, in view of the limitations of the study, it is recommended that studies with a more rigorous design (for downgraded factors) and larger sample size should be conducted in the future so that the conclusions above can be further verified through key result indicators.
