Lymphedema Prevention Surgery: Improved Operating Efficiency Over Time.

BACKGROUND: Lymphedema prevention surgery (LPS), which identifies, preserves, and restores lymphatic flow via lymphaticovenous bypasses (LVB), has demonstrated potential to decrease lymphedema in breast cancer patients requiring axillary lymph node dissection. Implementing this new operating technique requires additional operating room (OR) time and coordination. This study sought to evaluate the improvement of LPS technique and OR duration over time. METHODS: A prospective database of patients who underwent LPS at our institution from 2016 to 2019 was queried. Type of breast and reconstruction surgery, number of LVB performed, and OR times were collected. LPS details were compared by surgical group and year performed. RESULTS: Ninety-four patients underwent LPS, and 88 had complete OR time data available for analysis. Average age was 51 years, body mass index of 28, with an average of 15 lymph nodes removed. Reconstructive treatment groups included prosthetic reconstruction 56% (49), oncoplastic reduction 10% (9), and no reconstruction 34% (30). The number of patients undergoing LPS increased significantly from 2016 to 2019, and average number of LVB per patient doubled. In patients without reconstruction, the average time for LPS improved significantly from 212 to 87 min from 2016 to 2019 (p = 0.015) and similarly in patients undergoing LPS with prosthetic reconstruction from 238 to 160 min (p = 0.022). CONCLUSIONS: LVB is an emerging surgical lymphedema prevention technique. While requiring additional surgical time, our results show that with refinement of technique, over 4 years, we were able to perform double the number of LVB per patient in half the OR time.
