[Reconstruction of oncological defects of the perianal region].

In addition to the progressive development of surgical oncological techniques for malignant tumors of the rectum, anal canal and vulva, reconstructive procedures after oncological interventions in the perianal region represent a cornerstone in the postoperative quality of life of patients. Modern treatment modalities for rectal cancer with neoadjuvant chemoradiotherapy increase the survival rate and simultaneously reduce the risk of local recurrence to 5-10%, especially by cylindrical extralevatory extirpation of the rectum. The price for increased surgical radicality and improved oncological safety is the acceptance of larger tissue defects. Simple suture closure of perineal wounds often does not primarily heal, resulting in wound dehiscence, surgical site infections and formation of chronic fistulas and sinuses. The interdisciplinary one-stage or two-stage reconstruction of the perianal region with well-vascularized tissue has proven to be a reliable procedure to prevent or control such complications.
