Transposition Flaps for Reconstruction of Perianal Skin Defects After Tumor Resection

ABSTRACT Objective To investigate the application of transposition flaps in the reconstruction of perianal skin defects after tumor resection. Methods From September 2018 to December 2019, 16 cases of perianal skin defects were repaired with unilateral or bilateral transposition flaps. The wound size before closure ranged from 4 cm × 8 cm to 7 cm × 10 cm. Fourteen patients achieved primary healing. Wound dehiscence occurred in one patient at the flap tip, whereas a slight infection occurred in another patient, which healed after a dressing change. During the follow-up period of 3–6 months, all patients were satisfied with the perianal area both aesthetically and functionally. Conclusion Transposition flaps are a promising option for the repair of perianal skin defects after tumor removal. Owing to the simplicity of the flap design, the wide popularity of this flap type among surgeons is anticipated.
