Background:
The primary cosmetic and functional outcome following successful upper limb salvage using free tissue transfer can often be unfavourable, which may motivate patients to undergo secondary procedures. In this study, we sought to identify predictors for secondary procedures and to analyse the type and number of these procedures.
Patients And Methods:
Patients who underwent free tissue transfer to the upper extremity between 2010 and 2017 were included in a retrospective cohort study: patients with secondary procedures to optimise the functional and aesthetic flap design (S cohort) vs. control cohort (C cohort). A multivariate regression analysis was used to identify predictors for secondary procedures.
Results:
One hundred and twenty-eight patients were included in the study (S cohort 36, C cohort 92). All in all, 56 secondary refinement procedures were performed in a mean of eight months after the initial free flap reconstruction. Most of the defects in the S cohort were localised at the hand (53 %), and upper limb salvage was mostly accomplished by fasciocutaneous and adipocutaneous free flaps (S cohort 89 %). The most frequently performed secondary refinement procedures were direct partial flap excision (61 %), followed by liposuction (16 %) and the combination of both (17 %). Furthermore, 64 % of the secondary refinement procedures from the S cohort were combined with further surgical interventions to improve hand function, e. g. tenolysis and arthrolysis. Patients with defects of the hand received secondary procedures 2.4 times more frequently (p = 0.05). Also, patients with a good general health condition (ASA 1 and 2) were six times more likely to undergo a secondary procedure (p = 0.03).
Conclusion:
Secondary procedures are safe and frequently requested by patients following successful free flap upper limb salvage. In particular, this applies to patients who are in a good health condition and with free flaps to the hand. Therefore, we recommend the implementation of secondary refinement procedures in the reconstructive plan to increase patient compliance and satisfaction.
