Aim In this study, the technical aspects of intraoperative radiotherapy (IORT) application and its effect on early wound complications were evaluated. METHODS Fifty consecutive patients operated with upper outer quadrantectomy and intraglandular flap mobilisation and given IORT between 2013 and 2014 were included. Radiotherapy at a boost dose of 10 Gy was given to 21 patients. The control group consisted of 29 patients who were operated with the same surgical technique but were not given IORT. RESULTS The median age of the patients was 51.5±10.9 years. The average specimen weight was 266±83 g. The surgical resection margin evaluation with frozen section was negative in all patients. Four patients were reported to have involved margins at permanent sections. When both groups were compared in terms of early postoperative complications, there were 6 (28.5%) patients with seroma in the IORT group and 2 patients (6.8%) in the control group. While 5 (23.8%) patients were seen to have surgical site infection (SSI) in the IORT group, there was no SSI in the control group. There were 7 (33.3%) patients with delayed wound healing in the IORT group and 2 patients (6.8%) in the control group. While 2 (6.8%) patients had hematoma in the control group, there was no hematoma in the IORT group. While one (4.7%) patient was seen to have minor wound dehiscence in the IORT group, there was no wound dehiscence in the control group. CONCLUSION In this study, we concluded that IORT may negatively impact wound healing by increasing the incidence of seroma, SSI, and delayed wound healing in patients undergoing oncoplastic breast surgery. Increased awareness and preventive measures are necessary, especially in centers newly implementing IORT.
