[Cylindric Abdominoperineal Rectum Exstirpation with Partial Vulvar and Vaginal Resection as well as Perineal and Vaginal Defect Reconstruction by a Vertical Rectus Abdominis Myocutaneous (VRAM) Flap].

Introduction Patients with low rectal cancer or anal cancer undergoing abdominoperineal excision (APE) benefit from extended surgery and the subsequent avoidance of surgical "waisting" at the level of the puborectalis muscle. The method of cylindrical APE was introduced by T. Holm and led to a reduction of intraoperative perforations and involvement of circumferential resection margins, and subsequently reduced the risk of local recurrence. The use of myocutaneous flaps reduces perineal wound complications, which occur in up to 60% of patients with primary closure of perineal defects, especially following neoadjuvant radiochemotherapy. Flaps obliterate pelvic dead space, recruit well-vascularised tissue into irradiated regions, facilitate wound closure and allow for vaginal and perineal reconstructions. This video shows the technique of extended cylindrical APE with partial vulvar and vaginal resection and subsequent reconstruction of the posterior vaginal wall and the pelvic floor defect by a vertical rectus abdominis myocutaneous (VRAM) flap. Indication Locally advanced anal cancer with infiltration and fistula to the posterior vaginal wall without metastatic spread following neoadjuvant radiochemotherapy. Procedure Extended cylindric APE with partial vulvar and vaginal resection, construction of a descending colostomy with parastomal intraperitoneal onlay mesh augmentation, pelvic reconstruction with a VRAM flap and inlay mesh augmentation of the anterior rectus sheath. Conclusion From the oncological point of view, extralevator APE is superior to standard surgery. The use of myocutaneous flaps improves postoperative wound healing and quality of life.
