Local Antibiotic Administration Decreases Surgical Site Infections Following Extremity Sarcoma Surgery

Area of Science:

• Orthopedic Oncology
• Surgical Infection Prevention

Background:

• Extremity sarcoma resection carries significant morbidity.
• Surgical site infection (SSI) is a common complication.
• Effective strategies to prevent SSIs are crucial.

Purpose of the Study:

• To compare SSI rates in extremity sarcoma resection patients treated with local antibiotic powder versus those without.
• To evaluate the efficacy of intra-wound antibiotic powder in preventing postoperative infections.

Main Methods:

• A cohort study involving 83 patients undergoing extremity sarcoma resection.
• 25 patients received local vancomycin and/or tobramycin antibiotic powder.
• 58 patients underwent routine closure without local antibiotics.

Main Results:

• The local antibiotic group had larger tumors and longer surgeries.
• Postoperative SSI rate was 16% in the antibiotic group vs. 40% in the no-antibiotic group (p=0.043).
• Local antibiotics showed a significant reduction in SSI odds (OR=0.0747, p=0.0075).

Conclusions:

• Local antibiotic powder administration is effective in preventing postoperative infections after extremity sarcoma surgery.
• This prophylactic measure is beneficial despite increased tumor burden and surgical complexity.
