Abstract: Objective To investigate the effect of the clinical application of the hollow core “2” incision technique in oncoplastic surgery of breast cancer. Methods The clinical and follow-up data of 28 breast cancer patients who underwent hollow core “2”incision breast oncoplastic surgery in the department of Breast Surgery, Guilin TCM Hospital, from May 2017 to September 2018 were retrospectively analyzed, and the postoperative complications, aesthetic effect and recurrence were analyzed. Results The mean age of the 28 patients was 57.3 years, the mean hospital stay was 6 days, the mean weight of the resected tissue was 50.1 g, the maximum tumor size was 4.0 cm×3.2 cm, the minimum was 1.8 cm×2.0 cm, the mean operation time was 82 min, and the intraoperative median blood loss was 30.5 mL.One patient underwent a second positive margin resection.There were no complications such as seroma, fat liquefaction and tissue necrosis in all patients within 1 month after surgery.One year after surgery, the cosmetic effect was excellent in 18 cases, good in 8 cases, and general in 2 cases.
