QS22. Top Surgery in Transmasculine and Non-binary Patients With Obesity

Abstract

The flap success rate in the DIEP group was 100%. The alternative flap group had two partial flap failures, but none were total flap loss. The stacked flap group had only one total and one partial flap loss (success rate 97.7%). The overall complication rate was 19% in the DIEP group, 43% in the alternative flaps, and 13.6% for stacked flaps. The reconstruction flap method did have a significant difference in complication risk between the three groups (p-value 0.011). Compared to the DIEP flap group, alternative flaps (PAP or LAP) had a 3.107 higher risk of overall complication (p= 0.037). Stacked flaps, however, had a comparable risk for any complication to the DIEP flaps. There was no statistical difference in the number of secondary revisions needed or the total fat grafted between the three methods.Conclusions: Autologous breast reconstruction in low BMI patients yields successful and durable results in DIEP flap. This study shows that predictable results in the thin patient population can be obtained via alternate autologous methods beyond the gold standard DIEP flap.
