A Simple Technique Using Peri-Prosthetic Irrigation Improves Implant Salvage Rates in Immediate Implant-Based Breast...

Background and objectives: Implant-related complications leading to implant loss contribute to major morbidity in immediate breast reconstruction (IBR). Various techniques have been advocated to improve rates of reconstruction salvage. The objective of our study was to assess if a peri-prosthetic irrigation system was an effective adjunct to the conventional wash-out technique in improving reconstruction salvage rates. Methods: The study included patients who had immediate implant-based breast reconstruction from January 2015 to November 2020. The conventional technique of reconstruction salvage, using debridement, wash-out, and implant/expander exchange with systemic use of antibiotics, was performed for patients undergoing exploration for infection until May 2019. A simple technique using a continuous peri-prosthetic irrigation system with vancomycin (1 g/L normal saline over 24 h) for 2 days was added as an adjunct to the conventional technique. Treatment details and clinical outcomes were compared between the groups. The study was approved by the Clinical Governance department. Results: During the study period, 335 patients underwent IBR. A total of 65 patients (19.4%) returned to the theatre due to post-operative complications, of which 45 (13.4%) were due to infection. A conventional technique was used in 38 (84.4%) patients, and peri-prosthetic irrigation was used as an adjunct in 7 patients (15.6%). A total of 16 (42.1%) in the conventional group and all 7 (100%) in the irrigation group had successful reconstruction salvage. No patients had complications due to antibiotic irrigation. Conclusions: The peri-prosthetic irrigation system is a simple, safe, and effective adjunct to conventional techniques in improving reconstruction salvage in IBR.
