The need for antibiotic prophylaxis in elective laparoscopic cholecystectomy: a prospective randomized study

Area of Science:

• Surgical Infection Prevention
• Antibiotic Prophylaxis Efficacy
• Laparoscopic Cholecystectomy Outcomes

Background:

• The necessity of antibiotic prophylaxis in elective laparoscopic cholecystectomy is debated.
• Postoperative infection rates are a key concern following this common surgical procedure.

Purpose of the Study:

• To assess the actual efficacy of antibiotic prophylaxis in reducing postoperative infection rates.
• To determine if routine antibiotic use impacts infection incidence or severity in elective laparoscopic cholecystectomy.

Main Methods:

• A prospective randomized study was conducted with 84 patients undergoing elective laparoscopic cholecystectomy.
• Patients were divided into two groups: one received cefotaxime sodium (Group A), and the other received a saline placebo (Group B).
• Intraoperative gallbladder bile samples were cultured, and various clinical parameters were recorded and analyzed for correlation with septic complications.

Main Results:

• No statistically significant difference in the overall incidence or severity of postoperative infections was observed between the antibiotic and placebo groups.
• Bile culture positivity in patients with sepsis complications was similar across both groups (P = .91).
• Multivariate analysis identified diabetes mellitus and preoperative colic episodes as independent risk factors for infectious complications.

Conclusions:

• Antibiotic treatment did not demonstrate a significant impact on the incidence or severity of infections after elective laparoscopic cholecystectomy.
• The degree of bile contamination was also not significantly affected by antibiotic prophylaxis.
• Risk factors for infection include diabetes and recent colic episodes, suggesting targeted preventive strategies may be more effective.
