Line production system for multiple lymphaticovenular anastomoses

Area of Science:

• Microsurgery
• Vascular Surgery
• Lymphedema Treatment

Background:

• Multiple lymphaticovenular anastomoses (LVAs) traditionally require multiple surgeons and microscopes, posing resource challenges.
• A novel line production system (LPS) was developed to overcome these limitations in performing LVAs.

Purpose of the Study:

• To evaluate the efficacy of the novel LPS compared to the conventional dual microscope (DM) system for multiple LVAs.
• To assess the impact of LPS on lymphatic detection, LVA quality, and lymphedema improvement.

Main Methods:

• A comparative study involving an LPS group (novice surgeon with loupes, expert with microscope) and a DM group (both surgeons with microscopes).
• Data collected included lymphatic detection rate, lymphatic diameter, number and quality of LVAs, and lymphedema improvement (LEL index).

Main Results:

• The LPS group demonstrated a high lymphatic detection rate (81%) with a mean lymphatic size of 0.44 mm.
• Significantly higher rates of total and successful LVAs per hour were observed in the LPS group compared to the DM group (p < 0.01).
• The LPS group showed a significantly greater mean improvement in the Lymphedema Energy Level (LEL) index compared to the DM group (p < 0.01).

Conclusions:

• The LPS enhances the number and quality of LVAs, leading to improved lymphedema outcomes.
• This system requires fewer microscopes and surgeons, and reduces overall operating time, making it a more efficient approach.
