There are still some outstanding clinical technical challenges in breast surgery that are difficult to solve with conventional surgical methods. To address these problems surgeons have introduced the concept of minimally invasive surgery and lumpectomy techniques for the surgical treatment of breast diseases, as well as for the removal of anterior lymph nodes in breast cancer. Stage I-II breast cancer. The lumpectomy axillary lymph node dissection by liposuction method has significantly reduced axillary bleeding, prolonged operation time, shortened removal of axillary drains, reduced surgical incision, no incision infection, accidental injury, subcutaneous emphysema, fat embolism, etc. In the lumpectomy group, the incidence of restricted shoulder joint movement and numbness and pain in the upper arm were significantly reduced. The lumpectomy of axillary lymph node dissection by liposuction method can achieve the effect of traditional surgery, relatively reduce the complications, narrow the surgical incision, shorten the postoperative recovery time, and has a better effect of minimally invasive surgery. Regional lymph node metastasis is an important sign of poor prognosis of breast cancer. In addition to axillary lymph nodes, internal breast lymph nodes are also the first regional lymph nodes of breast cancer metastasis, especially for breast cancer occurring in the upper inner quadrant or central part. Metastasis or recurrence of internal breast lymph nodes is an important factor affecting the prognosis of breast cancer. The lymphatic chain of the internal breast at the level of the first to fifth rib cartilage should be cleared. The traditional extended radical surgery for breast cancer requires resection of 2 cm of the second and fourth rib cartilage on top of the conventional radical surgery, but the extended radical surgery is gradually replaced by radiotherapy because of the high trauma and complications. However, its application is limited by radiotherapy to the internal mammary lymphatic chain. In recent years, with the development of minimally invasive surgery, thoracoscopic endolymph node dissection for breast cancer occurring in the upper inner quadrant or central site has been advocated over conventional radical mastectomy. Istagilov reported that lumpectomy of lumpectomy endolymph nodes in breast cancer is superior in terms of postoperative pain level, amount of anesthetic, length of hospital stay, and incidence of intraoperative and postoperative complications, and that thoracoscopic endolymph node dissection is an efficient and less invasive diagnostic method. nechushkin also concluded that. Endoluminal lymph node dissection for breast cancer has demonstrated high diagnostic value by completing radical breast cancer surgery with minimal invasion, and has made it possible to reliably determine disease staging and to plan radiotherapy. In addition, the large field of view of the lumpectomy allows the detection of other metastases in the chest cavity. There are also some disadvantages to lumpectomy of endoluminal breast lymph nodes. For example, it requires double-lumen tracheal intubation and access to the chest cavity, which may increase the chance of complications such as pulmonary infection, pulmonary atelectasis, lung and vascular injury, and hemopneumothorax.
