Summary
A porcine model effectively trains minimally invasive reconstructive breast surgery techniques, enhancing surgeon skills and preventing complications. This study explored latissimus dorsi flaps and silicone implants in pigs.
Area of Science:
- Surgical Innovation
- Experimental Surgery
- Animal Models
Background:
- Minimally invasive reconstructive breast surgery techniques are under investigation.
- Surgical proficiency and complication prevention are key goals for human application.
Purpose of the Study:
- To evaluate a porcine model for training in minimally invasive reconstructive breast surgery.
- To assess the feasibility of latissimus dorsi flap and silicone implant reconstructions in pigs.
Main Methods:
- Four pigs underwent bilateral mastectomy and immediate reconstruction using latissimus dorsi (LD) flaps or silicone implants.
- Ultrasound-guided marking and endoscopic dissection were employed for LD flap elevation.
- Silicone implants were placed via a single incision.
Main Results:
- Eight reconstructive procedures were successfully performed without serious complications like bleeding.
- One pig experienced a second-degree burn due to heat dispersion during endoscopic dissection.
Conclusions:
- The porcine model is highly valuable for practicing minimally invasive breast reconstruction.
- It aids in verifying anatomy, planning incisions, selecting instruments, and improving operator skills.
- This model helps in preventing surgical complications before human trials.
