Assessing antibiotic effectiveness for reducing postoperative infectious complications in acute cholecystitis: a...

Area of Science:

• Surgical Oncology
• Infectious Diseases
• Clinical Trials

Background:

• Patients with acute cholecystitis (AC) often receive antibiotics to prevent infectious complications post-cholecystectomy.
• This study evaluated the necessity of antibiotic prophylaxis in mild-to-moderate AC requiring emergency laparoscopic cholecystectomy.

Purpose of the Study:

• To determine the clinical significance and efficacy of antibiotic administration in patients undergoing emergency laparoscopic cholecystectomy for acute cholecystitis.

Main Methods:

• A multicenter, double-blind, randomized controlled trial involving 370 patients with AC.
• Patients were randomized to receive either intravenous cefazolin followed by oral antibiotics or intravenous normal saline (placebo).
• The primary endpoint assessed was the rate of postoperative infectious complications.

Main Results:

• No statistically significant difference in postoperative infection rates was observed between the antibiotic group (7.6%) and the placebo group (7%) (P=0.842).
• Non-infectious complication rates were also comparable between the groups (11.5% vs. 16.2%, P=0.591).
• The study met its non-inferiority margin, indicating that withholding antibiotics did not lead to worse clinical outcomes.

Conclusions:

• Routine antibiotic administration did not significantly decrease infectious complications in patients with acute cholecystitis undergoing emergency surgery.
• The findings suggest that antibiotics may not be necessary for all patients with mild-to-moderate AC undergoing laparoscopic cholecystectomy.
• Further research may refine antibiotic stewardship protocols for AC management.
