Three-dimensional computed tomographic (3D-CT) lymphography precisely identifies sentinel lymph nodes (SLNs) for less invasive video-assisted breast surgery (VABS). This technique improves accuracy in SLN detection and aids in oncologic procedures.
Area of Science:
- Oncology
- Surgical Innovation
- Medical Imaging
Background:
- Video-assisted breast surgery (VABS) offers improved aesthetics and reduced invasiveness for various breast conditions.
- VABS is increasingly utilized for benign and malignant diseases, as well as sentinel lymph node biopsy (SLNB).
- The study evaluates the efficacy of 3D-CT lymphography in conjunction with VABS.
Purpose of the Study:
- To assess the precision of 3D-CT lymphography in identifying sentinel lymph nodes (SLNs) during VABS.
- To evaluate the cosmetic and therapeutic outcomes of VABS procedures.
- To determine the utility of 3D-CT lymphography for guiding SLNB within VABS.
Main Methods:
- VABS performed via a small incision (2.5 cm, or 1 cm for SLNB) using retraction.
- 3D-CT lymphography conducted the day prior to surgery, injecting contrast near the tumor/areola.
- Image reconstruction produced 3D visualizations for precise SLN marking and biopsy guidance.
Main Results:
- VABS was performed for 150 patients (19 benign, 131 malignant diseases).
- 115 SLNBs were performed, 74 utilizing 3D-CT lymphography.
- 3D-CT lymphography accurately depicted SLNs and their lymphatic pathways, crucial for metastasis assessment.
Conclusions:
- 3D-CT lymphography is a valuable tool for precise sentinel lymph node biopsy (SLNB) within video-assisted breast surgery (VABS).
- The combined approach enhances the safety and minimally invasive nature of SLNB.
- Accurate SLN identification via 3D-CT lymphography supports oncologic treatment planning.
