Abstract
Background Autologous breast reconstruction offers superior long-term patient reported outcomes
compared with implant-based reconstruction. Universal adoption of free tissue transfer
has been hindered by procedural complexity and long operative time with microsurgery.
In many specialties, co-surgeon (CS) approaches are reported to decrease operative
time while improving surgical outcomes. This systematic review and meta-analysis synthesizes
the available literature to evaluate the potential benefit of a CS approach in autologous
free tissue breast reconstruction versus single-surgeon (SS).
Methods A systematic review and meta-analysis was conducted using PubMed, Embase, and MEDLINE
from inception to December 2022. Published reports comparing CS to SS approaches in
uni- and bilateral autologous breast reconstruction were identified. Primary outcomes
included operative time, postoperative outcomes, processes of care, and financial
impact. Risk of bias was assessed and outcomes were characterized with effect sizes.
Results Eight retrospective studies reporting on 9,425 patients were included. Compared with
SS, CS approach was associated with a significantly shorter operative time (SMD −0.65,
95% confidence interval [CI] −1.01 to −0.29, p < 0.001), with the largest effect size in bilateral reconstructions (standardized
mean difference [SMD] −1.02, 95% CI −1.37 to −0.67, p < 0.00001). CS was also associated with a significant decrease in length of hospitalization
(SMD −0.39, 95% CI −0.71 to −0.07, p = 0.02). Odds of flap failure or surgical complications including surgical site infection,
hematoma, fat necrosis, and reexploration were not significantly different.
Conclusion CS free tissue breast reconstruction significantly shortens operative time and length
of hospitalization compared with SS approaches without compromising postoperative
outcomes. Further research should model processes and financial viability of its adoption
in a variety of health care models.
