Patients, whether outpatient or inpatient, want to understand the similarities and differences between open and minimally invasive breast lump removal surgery in order to help them decide on a surgical option prior to surgery. However, the information they provide is often very random because they have not done much similar surgery themselves or have only been exposed to open surgery in the past, because the US FDA passed a bill allowing the so-called minimally invasive, i.e., vacuum-assisted breast biopsy system to remove breast tumors in the 1990s (1996), and it is more common in China. It should have been carried out in the last decade or so. In our department, we have performed more than 400 cases of minimally invasive breast surgery, i.e., vacuum-assisted breast biopsy system, and we have performed various operations such as treatment of breast abscess, combined small incisional resection of huge tumor and removal of PAHG after breast augmentation by injection, etc. with good results. So to summarize some issues, I hope it will be helpful to you. Open surgery Common point Both open surgery and minimally invasive surgery can remove the tumor lesion completely, both can be performed in hospital and outpatient manner, and there is no significant difference in recurrence rate. Open surgery minimally invasive surgery is less technically challenging and easy to master. It is more expensive and requires ultrasound knowledge and hand-eye coordination. Under real-time ultrasound monitoring, the size of the surgical excision, the excision process and whether residuals remain after surgery Indications Only for excision of palpable lesions Can be used for palpable lesions and non-palpable lesions Complications Localized nodules, hemorrhage, less common Subcutaneous petechiae, hematomas, nodules, more common, appear and resolve over weeks or months Resolve over weeks or months, resolve.
