Efficacy of single-dose versus triple-doses perioperative antimicrobial prophylaxis in patients undergoing laparoscopic cholecystectomy
Abstract
Introduction: Although debatable, prophylactic antibiotics may be required for patients undergoing cholecystectomy for symptomatic gallstone disease with certain associated risk factors. Our study aimed to perform a non-randomised prospective comparative trial evaluating a single-dose pre-operative antibiotic versus a triple-dose prophylactic post-operative antibiotic in patients with symptomatic uncomplicated cholelithiasis undergoing laparoscopic cholecystectomy. Methodology: This study was a non-randomised prospective comparative study in a single institution. Two hundred patients were enrolled and allocated to two groups. Group A patients were given a single dose of pre-operative prophylactic antibiotic, and Group B patients received a triple dose of prophylactic antibiotic therapy. We also studied the bacteriological profile of bile in all the patients using bile culture and antibiotic sensitivity, and we analysed their association with post-operative surgical site infection (SSI). Results: All the patients were followed up on post-operative days 7 and 30. On post-operative day 7, 2% of patients in Group A and 1% of patients in Group B were found to have SSI, and no statistically significant difference in SSI between the two groups was noted (P = 0.558). On post-operative day 30, no patient was found to have a SSI in either of the two groups. Moreover, post-operative bile culture was obtained in all the cases, and 6% of patients had a positive bile culture. However, none of them developed SSIs on post-operative day 7. Conclusion: A single-dose pre-operative antibiotic is as effective as three perioperative doses in preventing SSI in laparoscopic cholecystectomy for symptomatic, uncomplicated gallstone disease. Our study did not associate port-site SSI with a positive bile culture.
