摘要

Purpose

Complex abdominal wall defects present major reconstructive challenges when restoration of fascial continuity must be combined with durable soft-tissuecoverage, visceral protection, and, in selected cases, functional repair. Although autologous flap reconstruction is well established for selected indications, its overall role across defect types has yet to be established.

Methods

A systematic review was performed in accordance with PRISMA guidelines (PROSPERO: CRD42023491916). PubMed/MEDLINE, Embase, Scopus, Web of Science, Cochrane Library, and Google Scholar were searched from inception to April 2026 for studies reporting adult autologous flap-based abdominal wall reconstruction. Given substantial clinical and methodological heterogeneity, data were analysed descriptively.

Results

172 studies comprising 4,421 patients were included. Pedicled flaps predominated (n=4,095, 92.6%), with free flaps used in 146 patients (3.3%) and mixed approaches in 180 (4.1%). Hernia-related pathology was the commonest indication (n=3751, 84.8%), followed by malignancy (n=470, 10.6%). Frequently used flap categories included anterolateral thigh, tensor fascia lata, rectus-based, and latissimus dorsi-based flaps. Flap selection was primarily defect-driven: fascia-bearing regional and turnover techniques were used mainly for structurally focused hernia repair, whereas composite flaps were used more often for oncologic, fistulating, traumatic, contaminated, or full-thickness defects. Common short-term complications include seroma, surgical site infection, and wound dehiscence. Flap failure and reported long term hernia recurrence were low. Free flaps were used more often for larger defects weighted mean 401 cm² vs 250 cm² for pedicled flaps), although size ranges overlapped.

Conclusions

Autologous flap reconstruction is a durable and versatile option for selected complex abdominal wall defects. Reconstructive strategy should be guided primarily by defect composition.
