ObjectiveTo evaluate the safety and efficacy of endoscopic techniques for diagnosis and treatment of breast diseases. MethodsRelated literatures of recent years were reviewed. ResultsA minimally invasive endoscopic technique can be performed through small incisions. This can contribute greatly to reducing postoperative pain, shortening recovery time, and achieving a good cosmetic outcome. Under endoscopy, meticulous dissection and hemostasis can be achieved. Endoscopeassisted subcutaneous mastectomy, immediate mammary reconstruction, sentinel lymph node biopsy and axillary lymph node dissection, for breast cancer can be performed safely. Endoscopic surgery can also be applied for the diagnosis and treatment of benign breast tumor and transaxillary removal of glandular tissue in gynecomastia. In addition, fiberoptic ductoscopy can be used to diagnose patients with nipple discharge. Endoscopic surgery for patients with breast diseases can offer an excellent cosmetic outcome and maintain normal physiologic functions without a noticeable scar. It helps to give the patients confidence and improve the quality of life. ConclusionBreast surgery is a good candidate for endoscopic techniques.
The sonographic features of male breast lesions, which underwent ultrasound examination in our hospital for the past 10 years, were retrospectively analyzed. Sonographic features of these lesions were standardized as BI-RADS image lexicon. The differences in ultrasonic malignant signs were assessed between the benign and the malignant diseases. Between the two groups, incomplete boundary was statistically different. The specificity was above 95% within the two groups in terms of speculated margin, echogenic halo, calcification, axillary lymphadenopathy, thickening of skin and eccentric of mass to the nipple. High-frequency sonographic examination has a high level of differential diagnosis for male breast lesions.
ObjectiveTo explore the value of ultrasound real-time tissue elastography in the differential diagnosis between benign and malignant breast lesions.Methods A total of 131 cases of patients with breast lesions who underwent ultrasound examination in the People’s Hospital of Guangan City between December 2010 and December 2015 were enrolled as the research object. The patients took conventional color Doppler ultrasound diagnosis firstly, and then took ultrasound real-time tissue elastography diagnosis. The lesions were scored with improved 5-scoring system respectively. By the strain ratio measure method equipped with the ultrasonic machine, strain ratio of the lesion was calculated, with 3.08 as the cut-off pont. The results were campared with the pathologic diagnosis.ResultsThere were 182 breast lumps in the 131 patients. The conventional ultrasound examination detected 128 benign lesions and 54 malignant lesions. By ultrasound real-time tissue elastography examination, there were 121 benign tumors and 61 malignant tumors. For the benign tumors, the elasticity imaging score was 1.74±0.81, and the elastic strain rate ratio was 1.83±1.22; for the malignant tumors, the elasticity imaging score was 4.45±0.59, and the elastic strain rate ratio was 8.68±5.58. The 182 breast lumps were all removed by surgical resection, and the pathologic examination showed there were 121 benign lesions and 61 malignant lesions. The accuracy, sensitivity and specificity of conventional ultrasonic diagnosis of breast malignant lesions was 76.4%, 59.0% and 85.1%, respectively; while the indexes of ultrasound real-time tissue elastography diagnosis of breast malignant lesions was 96.7%, 95.1% and 97.5%, respectively, and the differences were statistically significant (P<0.05).ConclusionReal-time tissue elastography is helpful in the differential diagnosis between malignant and benign breast lesions.
ObjectiveTo understand the application of vacuum assisted rotary cutting technique in benign and malignant breast diseases.MethodThe related literatures about the application of vacuum assisted rotary cutting technique in the breast benign and malignant diseases were reviewed.ResultsThe technique of vacuum assisted rotary cutting had been applied to the treatment of intraductal and phyllodes tumors. The non-lactation mastitis lesions could all be removed by this technique, and as a minimally invasive treatment for gynecomastia. It could guided by the color Doppler ultrasound, mammography and MRI, which could obtain enough tissue specimens for the screening and biopsy of early breast cancer. The indication of vacuum assisted rotary cutting technique should be further discussed in the breast conserving treatment of breast cancer.ConclusionsVacuum assisted rotary cutting technique has been widely used in treatment of various benign diseases of the breast and diagnosis and treatment of breast cancer. The best indication for operation should be determined based on clinical manifestations and auxiliary examination results.
Objective To review the research progress related to endoscopic surgery and robotic surgery for breast diseases, aiming to provide references for clinical practice. Methods The recent domestic and international literature on endoscopic surgery and robotic surgery for breast diseases was reviewed, then the challenges in their development, the innovative evolution of endoscopic surgery combined with clinical practice by our team, and its clinical applications were summarized. ResultsTraditional endoscopic surgery, despite its advantages such as minimal invasiveness, good cosmetic outcomes, and high patient’s satisfaction, has been limited in its development due to specific difficulties in establishing the operative field. Our team innovatively proposed the “reverse sequence method” and the Huaxi Hole 1 theory and methods, cleverly altering the surgical procedure sequence, adding small operative orifices to transform single-port operations into multi-port ones, effectively overcoming the challenges restricting the advancement of endoscopic surgery in the field of breast diseases, thereby enabling further proliferation of endoscopic procedures. In terms of breast endoscopic reconstruction surgery, the parachute patch technique has broadened the indications for reconstruction surgery, benefiting patients with a certain degree of breast ptosis; and the postoperative adjustment concept, through early intervention in the post-reconstruction breast shape, has further refined the reconstruction procedure. Robot-assisted surgery derived from endoscopic surgery theory has further enhanced the precision and stability of surgeries, reducing surgical risks; however, excessive time and economic costs are urgent issues that must be addressed. Conclusion Through theoretical innovations, endoscopic surgery has been applied in the excision and reconstruction of breast lesions, while robotic surgery shows promising applications in autologous breast reconstruction, especially in the latissimus dorsi reconstruction field. Nevertheless, the lack of high-level large-sample, multi-center randomized controlled clinical trials to confirm its surgical safety, oncological safety, and postoperative cosmetic outcomes is an important direction for future research.
