Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Efforts to reduce seroma after breast cancer surgery include meticulous techniques such as sharp dissection, the use of monopolar energy devices, and ligation of blood vessels and lymphatics. Recently, the bipolar energy sealing system has been increasingly used. LigaSure, which uses electric energy and pressure to denature collagen and elastin in tissue, has been shown to reduce surgical time and medical costs compared to traditional clamp-and-tie methods and advanced sealing systems in various surgeries, including breast cancer.
In breast cancer surgery, using a electrosurgical bipolar systems for ligating blood vessels and lymph nodes has several potential advantages. Traditional ligation using sutures or monopolar energy devices can be influenced by surgical technique and has drawbacks such as thermal injury to surrounding tissue. In contrast, the bipolar energy sealer applies both electric energy and pressure simultaneously, minimizing thermal injury to surrounding tissue while ensuring permanent vessel and lymphatic ligation.
A 2008 prospective study showed that using bipolar energy sealers in axillary dissection allowed for earlier removal of drains compared to conventional methods. Other studies have shown less blood loss, lower drainage output, and shorter hospital stays during surgery. Recent research has also reported new applications of bipolar energy sealers in skin-sparing mastectomy, indicating active use in breast surgery overseas. A study conducted at Severance Hospital in South Korea found that using bipolar energy sealers reduced drainage.
However, most of these studies were conducted abroad with a small number of reported cases, and the results mainly concern axillary lymph node dissection (ALND), which is where seroma is most often formed. With the decreasing trend of ALND due to advances in preoperative chemotherapy and radiotherapy, there is a lack of studies on whether using electrosurgical bipolar systems helps reduce seroma formation after sentinel lymph node biopsy.
