Summary
Sodium 2-mercaptoethane sulfonate (mesna) may improve capsulectomy outcomes. This study found mesna facilitated dissection, reducing operating time and difficulty in rabbit models, suggesting its potential as a surgical aid.
Area of Science:
- Plastic Surgery
- Surgical Innovation
- Biomaterials Science
Background:
- Capsular contracture is a common complication following breast implant surgery.
- Capsulectomy, the removal of the scar tissue capsule, can be challenging and risks tissue damage.
Purpose of the Study:
- To evaluate the efficacy of sodium 2-mercaptoethane sulfonate (mesna) in facilitating periprosthetic dissection during capsulectomy.
- To assess mesna's impact on operative time, blood loss, and dissection difficulty.
Main Methods:
- A rabbit model with textured saline implants was used to induce capsular contracture.
- Capsulectomy was performed, with mesna instilled on one side and saline on the other as a control.
- Surgical parameters (blood loss, duration, difficulty) and histological capsule characteristics were analyzed.
Main Results:
- Mesna significantly improved histological capsule intactness (p = 0.005).
- Operating time (p = 0.003) and surgeon-assessed difficulty (p = 0.003) were significantly reduced with mesna.
- No significant difference in blood loss was observed between mesna and saline groups.
Conclusions:
- Sodium 2-mercaptoethane sulfonate (mesna) shows potential as a chemical dissector to aid in capsulectomy procedures.
- Further clinical studies are warranted to confirm mesna's utility in human patients undergoing breast implant revision or removal.
