EP.WE.858Risk of Post-Operative COVID-19 Infection Following Breast Surgery

Aims To study the risk of post-operative COVID-19 infection in patients undergoing breast surgery during the height of the pandemic in 2020. Methods We continued to perform surgery for breast cancers and other urgent breast conditions during the pandemic in a dedicated “Green” operating theatre in a COVID-19-free hospital. NHS guidance regarding staff and patient COVID-19 screening and patient self-isolation period changed frequently during the study period, and recommended guidance was followed. PPE was worn by theatre team. Patient records were subsequently reviewed for a positive COVID-19 swab or a COVID-19-related hospital admission within 8 weeks of surgery. Results 96 consecutive operations were performed by 4 consultants between April and August 2020. All but 14 were for breast carcinoma. Median age 56 (21-89). Median ASA grade 2 (1-3). 64 patients had negative preoperative COVID-19 swabs, others in the early stages were screened with chest X-ray or CT. 83% (n = 80) were done as day cases. Among breast cancer operations there were 17 mastectomies, bilateral in 2 cases. There was no cases of COVID-19 positivity or COVID-19-related hospital admission post-operatively. Conclusions Breast surgery, done mainly as day case, did not predispose patients to COVID-19 infection in the postoperative period when guidelines were followed. Concern about postoperative COVID-19 infection should not be a cause of surgical delay in any future waves, which can be potentially harmful to breast cancer patients.
