A Prospective Randomized Study Comparing Electrosurgical Bipolar Systems Versus Conventional Electrocautery After Sentinel Lymph Node Biopsy in Obese or Preoperative Chemotherapy Treated Breast Cancer Patients
The efficacy of electrosurgical bipolar systems in axillary lymph node dissection for breast cancer surgery is well known. In this study, the investigators aim to determine whether using electrosurgical bipolar systems helps reduce seroma formation in high-risk patients undergoing sentinel lymph node biopsy (SLNB) for breast cancer surgery. The investigators will focus on patients who are expected to experience high drainage output after SLNB, especially those who are obese (BMI\>25) or have undergone preoperative chemotherapy.
• Women aged 20-80
• Candidates for breast-conserving surgery and axillary sentinel lymph node biopsy
• BMI over 25 or those who have received preoperative chemotherapy
• Overall performance status of Eastern Cooperative Oncology Group (ECOG) 0-2
• Participants who understand the study contents and can provide written consent
• Participants without evidence of distant metastasis
