OBJECTIVE Large full thickness abdominal wall defects following malignancies can be a reconstructive challenge. The purpose of this study was to analyze long-term outcomes and complications following abdominal wall reconstruction using composite antero-lateral thigh (ALT) flaps. METHODS The study retrospectively investigated 16 consecutive patients who underwent abdominal wall reconstruction with autologous flap between May 2003 and March 2018. Volumetric flap analysis was used to assess flap atrophy over time, evaluating the role of denervation and reinnervation. The long-term outcome was assessed to compare the two groups (free vs. pedicled ALT flap reconstructions). RESULTS All flaps successfully covered the defects. We found a significant increase in flap resorption in free flaps when compared to pedicled ones. Abdominal bulging was seen in 3 out of 16 (19%) patients after more than 12 months follow-up, in close correlation with mesh absence. CONCLUSIONS Free flaps were shown to be equally effective as their pedicled counterparts, without significant increase in complication rate.

D012189 Retrospective Studies Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.

D013524 Surgical Flaps Tongues of skin and subcutaneous tissue, sometimes including muscle, cut away from the underlying parts but often still attached at one end. They retain their own microvasculature which is also transferred to the new site. They are often used in plastic surgery for filling a defect in a neighboring region.
