Brief Summary

SUMMARY Rationale: Prophylactic antibiotics in laparoscopic surgeries, including Metabolic Bariatric Surgery (MBS), are routinely provided to reduce postoperative infections, especially at wound incision sites. However, since incisional wound infections in laparoscopic MBS are rare and morbidity is very low, the benefit of antibiotic prophylaxis is questionable. Objective: Evaluate the non-inferiority of omitting antibiotic prophylaxis in MBS. Compare postoperative outcomes between Group A (no antibiotics) and Group B (standard antibiotic care) to determine if omission increases complications, particularly wound infections. Study Design: Randomized controlled trial (RCT), double-blind. Study Population: Patients with obesity eligible for MBS. Intervention:

  • Group A (No Antibiotic Prophylaxis): Undergo MBS without antibiotics to test safety regarding postoperative complications, focusing on surgical site infections (SSIs).
  • Group B (Standard Antibiotic Prophylaxis): Receive standard one-time antibiotics before incision. Main Study Parameters/Endpoints: Compare the incidence of incisional and organ/space SSIs within six weeks post-surgery between Group A and Group B to determine if omitting antibiotics affects infection rates.

Outcome Measures

Primary Outcomes (1)

  • Comparison of incidence of postoperative wound infections in both treatment arms

    Aims to evaluate the non-inferiority of foregoing antibiotic prophylaxis in MBS. The study will compare postoperative outcomes between two groups: Group A, which will not receive antibiotic prophylaxis, and Group B, which will receive standard care including a one-time administration of antibiotics, to test the hypothesis that omitting antibiotic prophylaxis does not significantly increase the incidence of postoperative complications, in particular wound infections.

    until 6 weeks post operative

Study Arms (2)

NACL0.9%

EXPERIMENTAL

Group A will receive 100 ml NACL0.9% without any antibiotics in it.

Drug: NACL 0.9% 100 ml

Cefazolin +Metronidazole

ACTIVE COMPARATOR

Group B will receive 2000 mg of Cefazolin and 500 mg of Metronidazole IV dissolved in 100 ml NACL0.9%. Both antibiotics will be administered at least 30 minutes before surgery to ensure adequate tissue concentrations at the time of incision.

Drug: 2000 mg of CefazolinDrug: 500 mg of Metronidazole IV
