{Abstract}: UNASSIGNED: The large resection area of perianal tumor makes the skin defect hard to reconstruct. The keystone flap has demonstrated a growing application in skin defects. Herein, we aimed to explore the efficacy of keystone flap in the repair of skin defect after perianal tumor resection.
UNASSIGNED: This study is a retrospective review of patients diagnosed with perianal tumor from January 2010 to November 2021. A standardized data collection template was used to collect variables. The detailed process of the reconstructive surgery is carefully described in this article. After surgery, the healing process was closely observed.
UNASSIGNED: Twenty patients underwent keystone flap repair. The average wound size before closure measured 3.5 × 4.9 cm2. Primary wound healing was achieved, and the flap survived during the follow up period, which ranged from 6 to 24 months. No severe complications occurred; slight edema was noticed in one patient.
UNASSIGNED: The application of keystone flap is a promising way to repair skin defect after tumor removal, and the complications rate was low after surgery. It can be concluded that this method is an effective and reliable way to repair perianal skin defect.
