Abstract
Epidermoid carcinoma of the anal canal is a rare tumor, still unknown. Abdominoperineal resection (APR) is still required in about 20% of the patients during the evolution of the disease. Surgery has increased Overall Survival (OS) and Disease Free Survival (DFS), with a mean OS of 56% at five years. Mean prognostic factors are existence of metastases at time of diagnosis, size of tumor (T stage of TNM), nodes involvement, and complete surgical resection (R0). The surgery is especially mutilating, and has an important morbidity, with severe perineal wound healing. On the functional side, it is a traumatizing surgery, which impacts the quality of life because of confection of definitive colostomy, and has an important impact on several female sexual functions. A vertical rectus abdominis myocutaneous flap (VRAM) confection seems to improve morbidity and some functional sequels.
