Reconstruction Guideline Summary: In March of 2013, the Executive Committee of the American Society Work Group of Plastic Surgeons approved an evidence-based guideline on breast reconstruc- Arlington Heights, Ill. tion with expanders and implants, as developed by a guideline-specific work group commissioned by the society’s Health Policy Committee. The guideline addresses ten clinical questions: patient education, immediate versus delayed reconstruction, risk factors, radiation therapy, chemotherapy, hormonal therapy, antibiotic prophylaxis, acellular dermal matrix, monitoring for cancer recur- rence, and oncologic outcomes associated with implant-based reconstruction. The evidence indicates that patients undergoing mastectomy should be offered a preoperative referral to a plastic surgeon. Evidence varies regarding the as- sociation between postoperative complications and timing of postmastectomy expander/implant breast reconstruction. Evidence is limited regarding the opti- mal timing of expand/implant reconstruction in the setting of radiation therapy but suggests that irradiation to the expander or implant is associated with an increased risk of postoperative complications. Evidence also varies regarding the association between acellular dermal matrix and surgical complications in the setting of postmastectomy expander/implant reconstruction. Data support the use of an appropriate preoperative antibiotic, but antibiotics should be dis- continued within 24 hours of the procedure, unless a surgical drain is present. Furthermore, postmastectomy expander/implant breast reconstruction does not adversely affect oncologic outcomes. (Plast. Reconstr.
