Abstract
Autologous breast reconstruction, especially using the deep inferior epigastric artery perforator (DIEP) flap, is increasingly seen as a reliable, safe, and long-term alternative to implant-based reconstruction. Despite the recognized advantages of the DIEP flap for breast reconstruction, successful realization demands excellent anatomical knowledge, a thorough understanding of autologous breast reconstruction concepts and advanced microsurgical skills. Given that the porcine model is widely employed in microsurgical training, our study aims to assess this model using validated outcomes, with the objective of evaluating the enhancement in a surgeon's learning curve following training with this model. Forty DIEP flaps were harvested on 20 swines by a single surgeon in "Pius Branzeu Center" (Timisoara, RO) and "Drazan Institute" (University of veterinary of Brno, CZ) laboratories for microsurgical training in 6months (January 2015-June 2015). Then we analyzed data from 40 DIEP flaps harvested by the same surgeon on first 20 consecutive patients undergoing DIEP flap breast reconstruction. Perforator dissection time, surgeon-determined dissection difficulty score (DDS) and venous congestion rate were collected for each flap in porcine model and in patients, then compared and analyzed. The mean of DDS score analysis in first and second swines group dissection resulted as statistically significant (P-value 0.0001), while it was not statistically significant between those analyzed in the second group of swines dissected and patients (P-value 0.8037). Reduction in perforator dissection time between the two swines' groups and in venous congestion rates from the first swines groups to the second to the human group resulted statistically significant too (P-value respectively 0.0001 and 0.0079). The porcine model has been used for a long time together with other animal models for microsurgical training. Our study confirms and objective by validated scores that it is a valid and reliable model, comparable to the human one and which mimics the dissection of human perforating vessels.
