Background: Pelvic exenteration is a radical surgery performed in selected patients with locally advanced or recurrent pelvic malignancy. It involves radical en bloc resection of the adjacent anatomical structures affected by the tumor. The authors sought to evaluate the clinical application of a depithelized gracilis adipofascial flap for pelvic floor reconstruction after pelvic exenteration.
Methods: A total of 31 patients who underwent pelvic floor reconstruction with a gracilis adipofascial flap after pelvic exenterationat Peking University Third Hospital from 2014 to 2022 were enrolled in the study. The postoperative follow-up durations varied from 4 to 12 months.
Results: The survival rate of the flap was 96.77% with partial flap necrosis in one case. The total incidence of postoperative complications associated with the flap was 25.81%, with an incidence of 6.45% in the donor site and 19.35% in the recipient site. All complications were early complications, including postoperative infection and flap necrosis. All patients recovered after treatments, including anti-infectives, dressing change, debridement, and local flap repair. Long-term follow-up showed good outcomes without flap-related complications.
Conclusions: A depithelized gracilis adipofascial flap can be applied for pelvic floor reconstruction after pelvic exenteration. The flap is an ideal and reliable choice for pelvic floor reconstruction with few complications, an elevated survival rate, sufficient volume, and mild effects on the function of the donor site.
