ABSTRACT
Background:
Elective laparoscopic cholecystectomy has very low risk for infectious complications, ranging the infection rate from 0.4% to 1.1%. Many surgeons still use routine antibiotic prophylaxis
Aim:
Evaluate the real impact of antibiotic prophylaxis in elective laparoscopic cholecystectomies in low risk patients.
Method:
Prospective, randomized and double-blind study. Were evaluated 100 patients that underwent elective laparoscopic cholecystectomy divided in two groups: group A (n=50), patients that received prophylaxis using intravenous Cephazolin (2 g) during anesthetic induction and group B (n=50), patients that didn't receive any antibiotic prophylaxis. The outcome evaluated were infeccious complications at surgical site. The patients were reviewed seven and 30 days after surgery.
Results:
There was incidence of 2% in infection complications in group A and 2% in group B. There was no statistical significant difference of infectious complications (p=0,05) between the groups. The groups were homogeneous and comparable.
Conclusion:
The use of the antibiotic prophylaxis in laparoscopic cholecystectomy in low risk patients doesn't provide any significant benefit in the decrease of surgical wound infection.
HEADINGS:
Laparoscopic cholecystectomy; Antibiotic prophylaxis; Surgical infection.
